This weekend, my life purpose was reawakened. And it was important.
I had the chance to not only attend, but also speak, at the inaugural WordCamp US in Philadelphia.
But before we go there, let me share some related feelings.
The first WordCamp was held in 2006 in SF and I was one of a few people who had the privilege to speak to that audience. I don’t even remember what I spoke about but it was designed as an unconference.
Ok let’s go remedial for a moment to explain what an unconference is. A decentralized get-together where people who have an idea can share it… As opposed to an organized conference of your traditional means.
All this to say… WordCamps have trended more toward traditional conferences as opposed to a community-driven “dinner table” sort of thing.
But, while there have been hundreds, if not thousands of WordCamps since, across the globe – of which I’ve organized two – the “big one” that attracts attendees from all over the globe, has been WordCamp SF where it all began. And it has largely been spearheaded from the top down. It was an important move, inline with open source ethos, to democratize the big one. And so the Philadelphia WordPress community and WordCamp Philly organizers were given the opportunity to do “the big one”.
And boy did they do it.
There was a tone to this WordCamp that was different than every other WordCamp that, to my knowledge, has ever been organized.
You typically find WordCamps, generally organized for the regional community, catering to every level of user… From non-technical users wanting to understand how to market their content on Google, to talks about leaving a day job to freelance.
Wash, rinse, repeat.
There’s a reason why veterans in the industry typically hang out in the hallway talking to each other instead of going to sessions.
This WordCamp had a forward-thinking tone that had sessions oriented in such a way to challenge the norm and looked at what WordPress could be instead of what it was. It was truly amazing and inspiring.
Look, WordPress runs one out of every four websites you’ll visit today. It’s a gigantic responsibility but… Those of us who work with it every day also are the first to forget that. We treat WordPress like a job.Freelancers find a way to find gigs that will get them to their next gig. Agency folks take the tasks assigned by project managers and make them reality knowing that next week, we’ll have another task. Product folks keep building out features because a couple people want them.
We forget that every line of code we write contributes to humanity.
Every line of code enables a freedom fighter in the Middle East.
Every line of code expands the ability for an activist to achieve her intended goal.
Every line of code allows a young man in a Congolese village to communicate with his community isolated by physical obstacles like jungle.
Or sell a product they hand craft online to customers who can’t reach them.
It builds economy. It builds relationships. It builds humanity. It gives those who have less opportunity the ability to compete with those of us who have more.
I watched as Anthony D. Paul built a website using nothing more than a smart phone. Important because developing countries are being flooded with free smart phones where there is no Google Fiber or Comcast.
And what’s the most fundamental means of human evolution? Storytelling. Passing knowledge from one generation to another.
I got into this world… I spent hours of many nights over many years pouring myself into WordPress and I have admittedly allowed it to become my job. I forgot why I got into it. I lost my inspiration.
This weekend, I remembered. I want to change the world. Literally.
So thank you everyone who organized, sponsored with real money, the speakers and every single one of the hundreds of people I spoke with. You made WordCamp. You gave yourself to me, to the community and… By definition… The world.
Ever have those times that you’d like to share a piece of media but have it start at a particular time? I did recently, and figured I’d share my solution.
It turns out, WordPress does not support this feature out of the box (though you could argue, theoretically, that it should).
We just remembered the 50 year anniversary of the Selma march which was nicknamed Bloody Sundy as 600 civil rights marchers were attacked viciously by law enforcement in 1965. It seems appropriate to sample the MLK “I have a dream speech for this demo.
Now of course, it’s all a great speech worth listening to, but what if I want to start the audio at the place we all know?
Boom, just like that. The nuts and bolts of this are tied up in this code:
Simply, I filter the shortcode attributes for the audio and video shortcodes adding a new argument – “start”. This is in seconds.
Caveat: This will not work for media that is simply cut and paste. While WordPress will translate appropriate media URLs into embeds, it does not pass anything more than the required `src` argument.
Full source code, as a WordPress plugin, can be found on Github. (Pull requests encouraged)
If you’re in Baltimore and are a developer, or if you are in Baltimore and know someone who is a developer… Heck, if you’re in DC and are a developer or know a developer, we need you. (You can be to work in under an hour on the MARC train).
Some of you know what I do and who I do it for. I work for a company that has consistently been rated in the top 3 companies to work for. We’re fun and relaxed and our content producers focus on publishing in the financial industry.
Dogs are regularly in the office. We wear shorts and sandals to work. It’s an a-political group – as in office politics. Everyone works well together from the execs down to customer service.
We believe in “Fail cheap and quick” as a lean startup sort of mentality and everyone is empowered to just try stuff if it makes sense.
What *I* do is build awesome web technology to support the business. Plenty of WordPress but now we’re building out huge APIs for reporting and consumer-facing tools. And that’s not WordPress. That’s Laravel and MVC, if you’re curious.
We are looking to add another developer with real chops. PHP, JS, REST APIs, SQL for now with NoSQL as a viable thing for the future. We largely operate on Rackspace and Amazon EC2.
I’d love to hear from you or your developer friend. Send me your resume and cover letter but let me see your github as well!
Today, I went about setting up a local WordPress install for some development I am doing at work. The problem that existed is that I didn’t want to bring the database from the existing development server site into my local MySQL instance. It’s far too big. I figured this could be done via an SSH tunnel and so, I set abut trying to figure it out. The situation worked flawlessly and so, for your sake (and for myself for the future), I give you the steps.
Setting up the SSH Tunnel
I run a local MySQL server and that runs on the standard MySQL port 3306. So as these things go, I can’t bind anything else to port 3306 locally. I have to use an alternate port number. I chose 5555, but you can use whatever you want.
the -N flag means that when connecting via SSH, we are not going to execute any commands. This is necessary for tunnelling as, we literally, will not execute any commands on the remote server. Therefore, we won’t get a command prompt.
the -L flag tells SSH that we are going to port forward. The following portion, 5555:127.0.0.1:3306 combined with the -L flag means, literally, forward all traffic on localhost (127.0.0.1) connecting on port 5555 to the remote server’s port 3306 (standard MySQL listening port).
The remote server and ssh connection is handled by firstname.lastname@example.org. This seems obvious, but just in case. You may be prompted to enter your SSH password.
The final part can be omitted, but I like to keep it there so I know what’s happening. The -vv flag tells the SSH daemon to be extra verbose about what is happening with the connection. It’s sort of a good way to debug if you need to, and to know that the port forwarding is actually taking place.
Configuring WordPress to use the Tunnel
Now that we have a successful SSH tunnel, you have to configure WordPress to use it. In the wp-config.php file, simply modify the DB_HOST constant to read:
You need to add two more variables, though, to override WordPress’ existing siteurl and home options to allow you to work with the localhost domain, instead of redirecting to the remotedomain.com that is configured in WordPress.
With these configurations in place, loading up WordPress should now load in the database content from the remote host and you can get to work on local development. Word to the wise… don’t close the terminal window with the tunnel or the tunnel will be severed. If you have to minimize it so it’s not annoying you, go for it… just don’t close it.
For 7 years, I’ve been publishing these articles every time a new version of WordPress comes out. Since version 2.0. It’s been a long run. It began as a need to fill people in about new features in WordPress (and there were a lot in 2.0). There wasn’t anybody doing these at the time, and certainly WordPress wasn’t nearly as popular as it is now (22% of the internet is powered by WordPress).
But many more people have stepped up in recent releases and have started updating readers with new features and expectations. My job here is done. I’m passing the baton but really the baton has already been passed and I’m happy about that. This will be my final 10 things article. Thank you for sticking around and following along all these years.
On Wednesday (likely), December 5th, WordPress 3.5 will drop with all it’s gooey goodness. A BIG shoutout needs to go out to Andrew Nacin, the lead developer on 3.5, for project managing this release while also planning his wedding, and to his best man, core developer Daryl Koopersmith for leading the media efforts. And of course, all the other core contributors to this release (I, sadly, am not one this cycle).
So without further adieu, let’s get into the guts of 3.5.
One of the most anticipated revamps in WordPress history has finally arrived. Since the days of implementing the media upload integration, core developers, users and everyone in between has cried for a new way of managing media. It’s finally here and it is one of the biggest undertakings in WordPress core development history.
The new media manager in WordPress 3.5 simplifies the process of uploading various media formats (usually, but not limited to, images). Everything is right up front and easy to understand. Instead of having cryptic icons over top of the edit area on a post editing screen, you now have an obvious “Add Media” button.
Clicking Add Media brings up a dialog that has a very large, and obvious “drop zone” where you can drag and drop files into. This aspect has actually been around for a few versions, but now it’s a much smoother experience. Of course, you can also click the prominent “Select Files” button in the drop zone to pull up a more traditional dialog for selecting those media files and uploading.
You can also get a much more intuitive view of your already uploaded media attachment, select any number of photos and insert them into a post or create a gallery. This was all supported before, but the logical workflow makes the process a million times easier.
Also, gone are the days of uploading an image, having to close the media dialog to then re-open it to create a gallery or futz around with details for each image. This was always kludgey before. You could assign an image as a featured image without having to close the dialog, but then inevitably you’d end up in a situation where the dialog had to be closed to get into another image mode.
I’m really curious what the reaction to this feature will be.
Twenty Twelve is the new theme that is coming with 3.5 A few cycles ago, the core team decided to retire the old default “Kubrick” theme and release a new standard theme once a year. Twenty Ten came in 2010. Twenty Eleven came in 2011 and, well, obviously, Twenty Twelve is dropping in at the tail end of 2012.
Twenty Twelve is a fun theme. It’s fully responsive, so it conforms to different viewport sizes – monitors, iPads, smart phones, etc. In WordPress 3.4, the Admin got responsive love, and now the default theme gets it as well.
You can actually download and install it now, as it is also compatible with WordPress 3.4 and is on the theme repository.
This default theme has better typography, a home page template, various options for columns and widgeted areas and would serve well as a handy theme framework for child themes as well.
In addition, if you haven’t started leveraging post formats (available since WordPress 3.1), you can do that now with Twenty Twelve. The theme has built in styling defaults the match the sort of thing you’d expect from Post Formats (to me, still one of the most neglected things in WordPress)
HiDPI “Retina” Admin
For those of you on the retina display bandwagon, both Twenty Twelve and the entire administrative interface are all retina ready. No pixelation on those high-end Macs!
In WordPress 3.4, the first steps were made by providing quite a few retina (or hi-def, if you will – it will make more sense in a minute why I offer that clarification) icons in the admin. Now, the CSS (specifically for print) also supports this hi-def rendering. If you must print a tree, the print stylesheets will be printing in hi definition.
This also opens up opportunity as browsers and CSS3 continue to advance and provide developers with new tools.
Retina not only gives print versions additional clarity, and those high end Macs more beauty, but it also renders things better for you iPhone 5, iPad 3, Kindle HD and various new Android device users. Rejoice! (but I have an iPhone 4S, so meh!)
Removing the Links Manager
Oh my God. We finally got rid of this antiquated thing!
Remember back in the day when people actually kept blogrolls? And WordPress had this feature in the menu called “Blogroll”. And then people started realizing, as possibly one of the earliest turns toward WordPress not being only a blogging tool but also a full-blown Content Management System, that Blogroll just didn’t seem appropriate (or whatever the thinking was), so it was renamed to Links.
It’s now coming out entirely. Existing WordPress install retain the Links manager but new WordPress 3.5 installs no longer have this functionality.
If you still need it, you can install the Links Manager as a plugin.
As a developer, I am constantly setting up WordPress installs, setting up new WordPress installs, resetting WordPress installs, etc. so perhaps my favorite new feature in WordPress 3.5 is the “Favorite Plugins” doohickey. I always have a subset of plugins I use for development and functionality I consider a “must have” for a client project, etc.
If you go to the WordPress plugin repo (and are logged in with your WordPress.org username), you will see a new “Favorite” button on every plugin page.
This becomes incredibly useful in WordPress 3.5 where you can now pull down your favorite plugins with one-click install. When you visit the Plugins > Add New admin page, you will see a new “Quick Link” along side the “Upload”, “Popular” and other links that have been there all along. Now you just have a new menu.
This brings up a page where you can enter your WordPress.org username and get a list of all the plugins you’ve favorited on the plugin repo and install as you need.
Protip: Now you can stop emailing me and asking me what plugins I recommend. Enter MY username – technosailor – and find out which plugins I prefer.
Tumblr Importer Support
One of the most popular blog types and platforms in the past few years is Tumblr. Up until now, there hasn’t been a way to get Tumblr content imported into WordPress. That’s no longer the case.
On the Settings > Import page, you can now activate Tumblr import support. Warning: The process of importing Tumblr is a little kludgey and that is due to Tumblr’s own systems. You will need to register an app with Tumblr, enter certain key information about your WordPress install into the Tumblr app registration page, and copy certain key information into WordPress.
The instructions are all on the Import admin screen. I suggest opening up the Tumblr app registration page in a separate tab as you’ll have to go back and forth between Tumblr and WordPress.
Once you do this, you can connect WordPress to your Tumblr blog and slurp in all the data you’ve had over there. I know y’all love Tumblr, but this is your opportunity to get off of it and onto a more widely used and customizable platform. Plus, you have Press This in WordPress to allow you to continue your Tumblings.
The Dashboard has always been a bit of a sore spot for new users unfamiliar with WordPress. What is all this information? Unfortunately, that’s not going away quite yet. However, WordPress now makes it easier for users to get up to speed with common things like writing an about page, setting up a theme, etc.
In addition to Dashboard fixes, there have been a number of smaller UI changes in the admin, including the Privacy page being removed and merged into the Reading Settings pages. Lots of effort was put into a simpler user experience.
It’s the little things that help users get up to speed and using WordPress quickly and effectively and reduces the learning curve.
There are a couple of Multisite improvements for developers. For the longest time, well before the merge of WPMU into WordPress, the way developers could switch “context” from one site to another would be through switch_to_blog(). Even after the merge, that function still remained the way to do it. But it has always come at the price of performance and caching. It was an extremely expensive function to use, filled with unnecessary database queries and other fudge.
It left developers looking for ways to accomplish the same task in a different way – which is really not the WordPress way. We encourage developers to use the tools WordPress provides and not to try to get around them. This mentality is almost universal and prevents problems with backwards compatibility in the case of database schema changes, etc. However, this beast had never been tamed for this specific functionality.
As of WordPress 3.5, this function has now been refactored and performs significantly better than what it did, including massive caching changes. Developers should feel far more comfortable using it. Hooray!
Multisite: Sub Directory
Another Multisite improvement is the ability to install WordPress Multisite in a folder. Up until now, WordPress Multisite could not be installed in a subdirectory. It had to be installed in the document root which was… silly.
In WordPress 3.5, a lot of work was put into making it possible to do just that. Specifically, this came out of Hack Day at WordCamp San Francisco in August. Nice work Mark Jaquith and company.
One final developer tool that was added in WordPress 3.5 is a modification to the post__in argument that can be passed to WP_Query to affect what posts are pulled in a custom query/Loop. While post__in has been around awhile, and takes a comma separated list of post IDs to be retrieved, now, if the orderby parameter is set to post__in, the order of the IDs matter. Specifically, the order of the IDs in post__in is the order they are retrieved in the resulting dataset. Before they were simply ordered in numerical order (or whichever custom order parameter was supplied – post_name, post_title, etc) .
This is pretty effective for CMS-style usage of WordPress where a developer may want to have granular control of how specific content pages are listed, displayed, etc.
So that’s it! Nice big release. A lot of under the hood stuff for developers, but really this release is less of a developer’s release and more of a user experience release. When WordPress 3.5 drops on Wednesday (assuming that happens as expected), I’d love to hear feedback.
Thanks for reading all these years. I’m not disappearing. I’m just retiring from this column. Of course, I’m always looking for full-time or consulting work. Please feel free to contact me if you think we might be able to work together.
Six years ago, the first WordCamp ever was held in SF and it became the launching point for many local regions and cities to continue the conversation, learning and educating around WordPress. It was always meant to be a hyper-local thing. Actually, as a correction, it was never meant to be a thing at all. It was meant to be a get-together of SF WordPress people.
But surprise, it caught the attention of WP developers, users and designers worldwide (including myself), and we came in by storm!
The following year, the decision was made that, due to such high demand in SF, and to try to encourage WordPress user groups in other cities, WordCamps should be distributed and locally organized. That kicked off a slew of WordCamps that (seemingly) doubles every year. I organized WordCamp Mid-Atlantic (the roots for WordCamp Baltimore and WordCamp DC today) back in 2009 and 2010.
Personally, I’ve been at or spoken at dozens of WordCamps (Mark your calendars… if you’re in Las Vegas on October 6, I’ll be speaking there too). To name a few, I’ve been to WordCamps in SF, San Diego, Las Vegas, Raleigh, Baltimore, Miami, Atlanta, Dallas, Houston, and New York to name a few. I’ve been to San Francisco every year except one, and that was due to another travel conflict.
I’ve been an organizer, speaker, sponsor and attendee.
In other words, I am no rookie and I am in good standing in the community!
The WordPress Foundation
A few years ago, after some financial mis-management for a large WordCamp, the WordPress Foundation was setup. The Foundation was designed to promote the use of WordPress, protect trademarks of WordPress and related WordPress trademarks, including WordCamp. As part of this responsibility, the Foundation has issued rules around WordCamps via WordCamp Central. Today, I could not run WordCamp Mid-Atlantic the way I did before as the rules are quite rigid. On the other hand, I would also not have taken a nearly $3k personal loss on Mid-Atlantic in 2010, so the rules, in my opinion, aren’t all bad.
A sampling of these rules include that any WordPress-based commercial sponsors who distribute code must distribute 100% GPLv2 compliant software and having organizers approved. Also, all sponsorship money goes through the Foundation at this point.
Which leads me to a problem I feel the need to weigh in on. WordCamp San Francisco is no WordCamp. It is a conference in every rightful way of the word, as it should be. And it should be renamed as the WordPress Conference or something other that WordCamp. WordCamp SF is commanding massive sponsorship levels, of which one sponsor is gladly paying a whopping $30,000 for “California Street” level sponsorship.
Other sponsorship levels are at $10k, $7500, $5k and $2k.
This is against an unstated, yet enforced, Foundation policy surrounding limits for sponsorships. These rules were put in effect to encourage big companies, like Dreamhost who is in for $30k at WCSF, to spread the wealth among a variety of WordCamps instead of just one. The idea is that if, say Microsoft, was well-connected to an organizer of one WordCamp, the Foundation has mechanisms in place to move funds around to other less-connected, but still necessary, WordCamps. It also ensures that WordCamps don’t put their eggs in one basket and then have a major sponsor flake and leave them holding the bag. Fine, I can get behind that rule.
WordCamps also have rules about content. It used to be that every WordCamp had some session on using social media. While that is perhaps important to WordPress users, it’s not WordPress! So sessions need to be WordPress related. I totally get that and have no gripe with that provision. For the first WordCamp Mid-Atlantic, I invited Anil Dash to keynote, knowing that at the time, Anil was an SVP and Founder of a WordPress competitor. But it was open source and I felt that the competition only made us as a WordPress community stronger. I expected push-back from inviting Anil, and if the rules were in place then… he may not have been able to Keynote.
We know WordCamp SF is Matt’s baby and he chooses content, not based on whether if it’s WordPress-related, but whether it’s inspired him. At least that was true until last year when Jane Wells organized.
We also know food, photography and Jay Z inspire Matt, but I don’t think Rachael Ray would be a speaker at WordCamp SF… though perhaps I wouldn’t be surprised if she did end up speaking there. I digress.
Matt Mullenweg, who is both the President of Automattic, the commercial arm of WordPress, and the President of the WordPress Foundation responded to my request for comment by admitting that some content in the past has drifted from WordPress but that he still stands by them. “None of those speakers normally speak at WordCamps, but we’re able to attract them and orient them to contributing something interesting to the WordPress community because of WCSF’s location and prominence.”
I suppose, again, Rachael Ray could speak and discuss the merits of using WordPress for a food blog.
Related, ticket prices are kept artificially low, but sponsorship levels are extremely high. It feels wrong.
The Foundation does suggest lower ticket prices (around $20 is typical), but one wonders why WordCamp San Francisco could not charge a reasonably low rate of $200 for an attendee ticket, given that people would still come from all over the world to attend. This would also lower sponsor levels and cause less controversy. DrupalCon is charging $400-$450. RailsConf is approximately $800. Why does the official WordPress conference have to sell at $20 when sponsorship levels feel inappropriate?
The Foundation Risks Major Implications from Non-Enforcement
When the Foundation was established, it’s stated goals were inspired by the Mozilla Foundation, as much of the philosophy of open-source development and products in the WordPress world are. It’s important to point out that, from a governance standpoint, the Mozilla Foundation and Mozilla Corporation, though closely tied, are governed by different people with similar but differently stated goals.
If Mozilla Corp goes outside the bounds of protected Mozilla.org auspices, you better believe that Mozilla.org is going to have something to say about it. The reason is simple… if you don’t enforce your own policies with your closest ally, friend and organization made from the same DNA, you leave yourself open to risk later on. Otherwise, you have a conflict of interest which is both legally and publicly difficult to reconcile.
Trey Roberts, a well-decorated Intellectual Property attorney of Roberts & Roberts in Austin, TX, commented to me that, “Though there is no ‘discrimination’ in a legal sense, since an organization has the right to choose what aspects of their licensing contract to enforce, if a pattern of suspended enforcement occurs, there is a risk of legal repercussions.”
Of course, some organizers see a level of subjectiveness in Foundation rules. Tony Perez, one of the organizers of WordCamp San Diego, lamented, “Often case when a request would be made, the response would be,’we would prefer not.’ When the question was asked, ‘well why not?’ the response was not very clear or decisive, so the decision felt as if it was in limbo. At the same time, you almost felt bad going against the recommendation, so it starts to become easier not to ask, than to ask.”
Opportunity exists though. “I can say though that it’s a necessary evil, but perhaps its time to think outside the box on the approach,” says Perez.
I love WordPress
I write this post not to bash WordCamp, the WordPress Foundation or any individual involved. In fact, I love WordPress. My professional career is Proudly Powered by WordPress. I want the Foundation to succeed as an organization charged with the governance of the software and events around it – and it is making strides to become a respected, independent governing organization. But conflicts of interest (or perceived COIs) do not provide a healthy community atmosphere and it causes bad blood among other WordCamp organizers. It, in fact, keeps potential organizers from wanting to jump in the mix. Or former organizers (like myself) from wanting to participate.
One former organizer, Amanda Blum, who has been a frequent critic of the Foundation tells me she won’t organize another WordCamp but she “still actively advises other camps [sic]” and “all I hear is complaints”. She goes on to express a concern about “the vast chasm between what the Foundation thinks Camps [sic] purpose is, and what the attendee interprets.”
Policies of the WordCamp Foundation around WordCamps are heavy-handed, in my opinion. There should be education (and there is some) around how WordCamps should be organized. Perhaps the rules that require WC money to be funnelled through the Foundation are merited (I actually do agree with this for non-profit reasons). However, where possible, it strikes me as necessary (and in fact, opportune) for local organizers to be able to blaze their own path and put their own local stamp on their own local WordCamp in almost every case. When it comes to sponsorship level, a WordCamp in NYC is likely going to cost more on orders of magnitude than a WordCamp in Omaha. One size shouldn’t fit all and the discretion should be left, with guidance from the Foundation, at the local level.
Mullenweg states, “The guidelines on Central encourage lower per-company sponsorship levels to encourage more sponsors per WC, decrease reliance on a single sponsor (we’ve had them flake out before), and have a level where even smaller firms can participate. It also hasn’t appeared to be a hindrance to larger city WordCamps, with NYC and Boston both raising 20k and putting on great events.”
Jane Wells, who helped to draft the original rules, tells me that the Foundation does try to not take a one size fits all approach to WordCamp’s and that they try to assist local WordCamps with financial assistance for venues, etc when needed. It does seem there is a perception among many organizers like Perez that this is not the case. One area where better communication between the Foundation and organizers may occur is at a new community blog that just went up.
With the spirit that this article is written with, I hope the Foundation, Automattic and the community take this as constructively confrontational. I do not wish to throw anyone under the bus, but change needs to happen for the integrity of the community. I cannot and will not be attending WordCamp SF this year or in the future, as long as these grievances continue year after year. I, however, will be at WordCamp Las Vegas and possibly Baltimore in the months to come, and I hope to see you there.
Corrections: Inserted a reference to WordCamp Central that serves as a central organization point for WordCamps. Also, updated the date for WordCamp Las Vegas to Oct 6, 2012. Corrected some content flow (paragraphs inserted in the wrong place) and noted that Matt did not choose content in 2011.
WordPress 3.4 is around the corner. It’s currently beta4 which means a Release Candidate or three will be needed before it drops officially. If you want to test what’s out there now, the way to do that is through SVN. As usual, however, pre-release WordPress is not supported. As usual, however, I have been running trunk throughout the entire development cycle without any problems.
Before I get into the guts of WordPress 3.4, I want to point you to a resource which highlights some of the thinking that is going into the development, now and in the future, of how WordPress is built. Andrew Nacin sent an email to the “hackers” mailing list discussing object-oriented development that informs the thinking of the core developers now that WordPress supports PHP 5.2 and true object-oriented programming.
While it may be over the head of non-developer types, the gist is that now that we (used loosely) can write code smarter, we’re working our way in that direction. Some of the code in WordPress has existed for “generations” of versions and is bulky and inefficient. With new tools at our fingertips, we can begin to approach the idea of refactoring some of this code in better ways. Backwards compatibility is always retained, however, in 99 out of 100 times.WE ARE NOT DRUPAL!
Without further adieu, however, let’s get into what you can expect in the new version of WordPress.
Embed Tweets with oEmbed
Since version 2.9, WordPress has supported a technology called oEmbed that, simply put, has allowed the inclusion of rich media in content in a very simple way. Simply paste a YouTube link on a new line, and WordPress turns it into a properly sized video. No embed code needed. Same for Vimeo, Flickr, Scribd and more. The entire list can be found on the Codex. Now, however, Twitter is supported. Simply place the URL of a tweet on it’s own line and… bam, you have this:
Twitter is an oEmbed provider that is supported out of the box in WordPress 3.4
The common bottleneck for all WordPress users are database queries and data “munging”… that is, what WordPress does with data when it’s returned from the database. The query that brings in all the necessary content necessary to render a page used to look like this:
SELECT*FROM wp_posts WHERE...
This has been how the query has worked for years. Really since the beginning of WordPress. And while, in theory that works (and it does, again it has for years), the core reality of this approach is that all the data in the posts table matching the criteria in the WHERE clause is more data than is needed, thus causing potential performance problems.
This approach means the amount of data in memory and floating around WordPress is concise and compact. PHP doesn’t have to work harder to traverse arrays or objects… it is simply a smaller list of data.
But what about the other data? We need the other data! Yes, in fact we do. But since WordPress has an object cache, much of this data is in the object cache. We don’t need to retrieve it from the database.
The second step is to look to the object cache for posts with IDs matching any of the IDs in the first dataset. Anything we can’t find is followed with a second query to get all the information matching the non-matched IDs using MySQL’s IN() function:
SELECT*FROM wp_posts WHERE ID IN(10,34,78);
By changing how SQL and object caching is used, WordPress 3.4 finds new efficiencies. In the original ticket, developers were observing 2-3x speed performance improvements. I’ll drink to that.
Non-technical WordPress users will love the new Theme Customizer. Otto has a great write-up on this new feature. His video is above. The key takeaway from this new feature is that is possible now to customize a great number of things in a theme from right within WordPress. On the fly. with a live preview.
Change your title, tagline, background color, image and more with a click of a mouse. I can see this being used to create child themes in the future, but for now, it manages settings that are already in WordPress (and accessible in other areas of the WordPress Admin) on the fly. The best way to really appreciate this feature is via Otto’s video above. Related: The best way to leverage this as theme developers is outlined in great detail in his post…
Bundled ‘Touch’ Support
We live in a touchy-feeley world. And by that, I mean mobile. Specifically iOS and Android. In WordPress 3.3, we saw adaptive design come to portions of WordPress. Adaptive design, for the uninitiated, is a technology that elegantly resizes a website to adapt to the the screen it is rendered on. It is a way for developers to create a single experience that works on desktop/laptop browsers as well as mobile interfaces with arbitrary resolutions.
As mobile continues to lead the charge in today’s web, WordPress 3.4 has bundled the jQuery UI Touch Punch library that will give front-end developers more tools to work with in making a website mobile-friendly. Simply include the library via wp_enqueue_script() and now your element has the .draggable() method available. This method enables “drag and drop” support that was previously unavailable and the one major caveat is that it does not support Windows 7/7.5 phones due to limitations in the IE9 browser.
I’m trying to rotate between developer tools and user tools in this article, so at this time, I’d like to point out a simple yet important frustration in previous versions of WordPress. When you upload an image and use the media uploader to then insert an image, you have the option of writing a caption. Sadly, it was impossible to include HTML in previous WordPress versions.
Often times, linking the source of a photo is welcome and, possibly depending on the usage restrictions on a photo, required. Before, the only way to do that was to set a link in the media uploader and then the photo would be linked. Now, in WordPress 3.4, you can include basic HTML in your captions as I have done above.
XML-RPC. The thing that allows the WordPress apps for Android, BlackBerry and iOS to function. The thing that allows offline editors to function by remotely communicating with WordPress through a public-facing API.
XML-RPC is a venerable technology that is based mainly on the Metaweblog API invented a decade ago. WordPress has supported this iteration of XML-RPC as well as the Movable Type XML-RPC and Blogger XML-RPC APIs for a long, long time. However, WordPress has also extended the Metaweblog API and added it’s own methods along the way.
No more. Instead of band-aiding a solution on top of a limited set of methods intended for blogging only, WordPress 3.4 includes a brand new WordPress XML-RPC API designed to support all the rich features that have evolved since WordPress started focusing on CMS-style features. It incorporates all the methods introduced before as extensions to Metaweblog such as wp.getOptions, wp.getMediaItem, etc and introduces new ones such as wp.getPostTypes and wp.getTaxonomies to name just a few.
It’s important to note that only WordPress products are likely to ship with support for this new API at first, but old capabilities will still exist and function, as backwards compatibility is ensured. As API clients add support for WordPress’ new capabilities, we will see more common usage.
Internationalization (i18n) Improvements
For international WordPress users, WordPress 3.4 continues the tradition of enhancing your experience. As we in the community have stated many times, i18n is incredibly important to WordPress growth and development. In discussing this article with someone inside of the WordPress core community, I am told 2 out of every 3 WordPress users are non-American. Additionally, I am told that 40% of WordPress installations are non-english.
The running list of i18n changes in WordPress 3.4 is here. Some notable changes include:
Comma translation. While most languages use a comma as a separater (or delimiter), some do not. This enhancement is useful for languages like Chinese and Arabic that don’t use a comma.
Single-Double quote translation. It’s odd to think, but some languages like Hebrew, actually have distinct meanings for jots that are punctuation marks in an English world.
Default Timezones. It’s possible now to override the timezone WordPress uses in a translation. This, as you can imagine, is important when a language is largely spoken in one region in a single timezone.
Page Template Handling
For theme developers looking to put more organization around their theme file structure, a new change has gone in that has both an obvious, front-facing benefit as well as a background benefit. Now, you can place any page template inside a subdirectory of a theme. So you can now have a /pages/ subdirectory and segregate all of your extraneous one-off or multi-use page templates to that folder (or any folder). WordPress will identify all page templates in the theme root or in a subdirectory of a theme root and make them available for pages to use.
The background benefit of this comes in a new WP_Theme API that is lighter weight, more efficient and handles all the work for you. It’s important to note that most developers will never need to use this API and it is largely considered an “internals” thing.
In relation to the i18n improvements discussed earlier, the headers in these page templates are also now translatable. Simply include a Text Domain: and Domain Path: header in your style.css where the textdomain is the defined textdomain for translations (i.e. twentyeleven) and the Domain Path is the path relative to the stylesheet directory (i.e. the proper place the theme is regardless of if it’s a parent theme or a child theme) where the POT file is (/langs). I don’t want to get too deep into this as Andrew Nacin, the architect of this feature, plans to put out a field guide going into detail. Stay tuned to that.
Custom Header API
For a few versions now, WordPress has supported two functions add_custom_header_image() and add_custom_background(). These two functions have added new menus for designating header and background images to the Appearances menu.
WordPress 3.4 introduces a new API for dealing with custom headers and backgrounds and introduces new flexibility in terms of image sizes, etc. The two functions above have been deprecated (which means they’ll work for awhile but will ultimately go away, so use the new techniques) and replaced with new theme support. If you recall from previous version, we use the add_theme_support() function to, well, add support for a feature in a theme. To integrate the new stuff, include these lines in your theme functions.php:
Both function calls can take a second argument which must be an array of presets, but it’s entirely optional. To omit the second argument renders behavior as we’ve known it for some time. To include it allows theme developers to designate designate parameters for both elements, that can then be customized by the end user.
For custom headers, you may include defaults along these lines (gregariously stolen from the Codex):
PHP end of file closing PHP tags are now removed. Those are these – ?> Why is this important? Including the closing tag means that if there is any white space at the end of a file, PHP is likely to break. Omission means that PHP assumes a close tag at the end of the file and whitespace can’t corrupt. Personally I’ve argued for this in the past. The main opponent must have been in a coma when this was slipped through by other core developers.
Distraction Free Writing, first introduced in WordPress 3.2 is now supported by all custom post types.
The theme installer now has infinite scroll which is just kind of pretty aesthetic thing. It also defaults to keyword searches when you’re browsing for a new theme on the WordPress Theme repository.
Internal functions and classes now output “rtl”, “ie7”, “ie8”, etc as classes for browser targetting.
Today, we get into customizations. It does us no good to have an SVN repository with WordPress if we don’t change it to be something other than what it is. In this episode I talk about adding plugins (and you can add any file, really) by adding it to the working copy folder and then checking it in.
I also touched quickly on svn:externals, although I note that I goofed in the screencast and typed
Last time, I talked to you a bit about setting up a clean subversion repository for your WordPress build. Today, I want to take that a step farther and help you bring WordPress into working copy and commit it into your repo.
