There are at least a dozen places on the web where you can find a discussion forum for help building WordPress sites including WordPress Development, WPChat, Advanced WordPress and PostStatus' Slack to name four. And on those various forums hardly a week goes by when someone does not ask a question of the form: "How… Continue reading
Embrace the Circularity! Recursion in PHP for WordPress
Background I recently commented on Tom McFarlin’s blog post entitled “Updating a WordPress Post in the Save Post Action” and suggested the use of a simple static variable rather than go through the hassle of removing and re-adding the save post hook.

Always Omit Closing PHP Tags in WordPress Plugins
Reader Odai left a great question in his comment today on our plugin tutorial: Looking at the code for The Complete Plugin, do you need to have a closing ?> for the opening <?php? Or is it okay to just end with a }? I learned the answer to this a long time ago, so… Continue reading

In our tutorial “Using Classes as Code Wrappers for WordPress Plugins” we took a plugin that used a global function for its filter hook and converted it to using a PHP class as a code wrapper. Unfortunately the approach we showed didn’t allow other plugins and/or themes to remove or chain the actions and/or filters… Continue reading
Using Classes as Code Wrappers for WordPress Plugins
Many tutorials that explain how to write a WordPress plugin (including ours) show the use of global functions for implementing action and filter hooks. In our case we used global functions so we had less to explain. But now that we’ve gotten past that first tutorial we think once you understand using classes you’ll find no… Continue reading
