Adding Stuff To WordPress “Screen Options”

June 29th, 2010

The Screen Options pull-down is the perfect place for those “rarely used but nice to have” settings. It’s unobtrusive and saves screen space. Some plugins could even put all of their settings in this panel and avoid cluttering the Dashboard menu with yet another “Settings” page. While Screen Options were already present in older WP […]

How To Filter The Whole Page In WordPress

May 20th, 2010

WordPress has numerous hooks for filtering posts, comments, feed items and more, but no built-in filter that would let you intercept and modify an entire page. However, you can do that fairly easily with PHP’s output buffering functions. Today I’m going to show you how. Crash-Course In Output Buffering As the name implies, output buffering […]

Only 2% Of WordPress Plugins Compatible “For Sure”

March 25th, 2010

Last October, the WordPress.org plugin directory introduced a new “Compatibility” feature that allows users to vote on whether a given plugin version works or doesn’t work with a specific version of WordPress. The idea was to provide a more reliable indicator of plugin compatibility so that you wouldn’t need to worry if upgrading will break […]

The Barest Page Templates Possible

February 25th, 2010

Some WordPress themes include custom page templates that let you add a custom layout or some nifty feature to specific pages. But sometimes you need the exact opposite – a page to be as bare, unadorned, downright plain as possible. No header, no menus, no nothing – just the HTML that you entered in the […]

The Viralogy Offer

February 4th, 2010

In this post I will explain what the “Viralogy.com script” thing mentioned in the Broken Link Checker survey was all about, discuss the user response and attempt to verbalize my rather unclear thoughts on the issue.

How To Make WordPress Check For Updates Immediately

October 1st, 2009

WordPress automatically checks for plugin, theme and core updates once every 12 hours. This is normally fine, but it can become annoying when you know there’s an important update or bugfix available yet it won’t show up in your Dashboard until the next time WP gets around to checking for it. Of course, you can […]

Spam Killed My Backups

April 21st, 2009

Having up-to-date backups is an essential safeguard in case something goes wrong with your website. So some time ago I installed WP-DBManager and configured it to send a daily backup of my WordPress database to my GMail account. All was well, until last week the backup process failed five times in a row. Upon checking […]

Make Your Plugin Faster With Conditional Tags

February 22nd, 2009

One of the reasons why WordPress can be slow is that it loads all active plugins on each and every page, even if some of those plugins aren’t actually used on that page. For example, an active anti-spam plugin will still be loaded even if the current page doesn’t contain a comment form (e.g. category […]

February 15th, 2009

Say you stumble upon a WordPress blog that has a gorgeous design. Amazed, you wonder what theme they’re using. Of course, it would be straightforward to just email the blog’s author and ask, but it might take a few hours (or days) until they get back to you. Here are three simple ways to identify […]

Top WordPress Plugin Niches

February 11th, 2009

As a plugin developer, I sometimes wonder what makes a plugin popular. How come some plugins garner hundreds of comments and thousands of downloads, while others pass quietly into the archives? What kind of plugin do the users want? Obviously the plugin’s niche (what kind of stuff it does) would be a huge factor. For […]

WordPress API Resources

January 14th, 2009

[Here’s some list-cliche-filler stuff while I fight off a (hopefully) temporary bout of unproductivity and dentists] WordPress internals are documented pretty well, but sometimes finding the right API/Codex page can take a while. That’s why I’ve decided to put together a comprehensive list of all APIs used by WordPress to serve as a “jump-off point” […]

How To Speed Up Sociable

January 10th, 2009

I’ve always cared about WordPress performance. I’ve optimized my database, tweaked the server’s configuration, used plugin profilers and installed WP Super Cache and PHP Speedy WP – the “heavy artillery” of performance-related plugins. However, only recently did I decide to finally track down and fix all the remaining subtle issues that may cause slow loading […]

Displaying Recent Posts On a Non-WordPress Page

November 15th, 2008

Listing recent posts on a WordPress page is easy – there are various widgets and theme functions available just for that purpose. But what about a non-WP page, or even a different site? That’s not that hard either – simply grab some posts from the blog’s RSS feed and output them on your page. In […]

The Benefits of Using Hooks Instead Of Plugin-Specific Functions

September 21st, 2008

Lets talk about that plugin-related code you have to put in your theme files when you want to add something nifty to your blog, like a “Related posts” feature or AdSense ads. It occurs to me that most plugin authors have been handling this the same way – you get a custom function that you […]

WordPress Version Survey

March 10th, 2008

A while ago I saw the blog version survey at BlogSecurity.net and got an idea to do my own. The previous survey is more than 8 months old and several new WordPress version have been released since then, so I think a new study is in order 🙂 I collected a large list of WordPress […]

Comment Spam Down By 96% – It’s Simple

November 17th, 2007

For months I’ve been getting dozens of spam comments, sometimes over a hundred per day. Most of them are caught by Akismet, which is great. The problem is that with high numbers of spam comments it’s virtually impossible to look through the spam filter logs and de-spam false positives. The bandwidth and processing power wasted […]

Make A WordPress Plugin Now! – Plugin Generators of Doom

November 10th, 2007

I’ve been following WP plugin development-related news for a week or two now, and I’ve noticed something that could make creating a plugin easier – plugin generators. These tools can create a handy template for your new plugin so you don’t need to start completely from scratch; you still need to know (at least) PHP to make your plugin do anything useful, though. In this post I’ll review three WordPress plugin generators I’ve come across.

WordPress Killed My Code

August 2nd, 2007

…but that’s okay – WP-Syntax resurrected it. After looking at one of my earlier posts I noticed that all the backslashes were gone from my code examples, most notably my regular expressions. I had the code wrapped in <pre></pre> tags. As some searching revealed, this seems to be a recurrent bug in WordPress 2.2.1 (I […]
