This WordPress plugin allows you to create sections of text in your post or page which expand/collapse when clicked on. You simply wrap the special tags around your text, and set the ‘expand link’ (the link visitors click on to show the text). If your visitors do not have javascript enabled, the ‘expand link’ is not shown, and the text is displayed normally. More »

This is the WordPress plugin version of my secure PHP form mailer script. This plugin has a wide range of features including: Support for multiple instances, an easy to use dynamic form generation system (any number of fields, in any order), multiple recipients, multiple file attachments, optional auto reply feature, an image verification system, numerous security features (including protection against email header injection), a message template system, multiple languages, and too many other things to list. This plugin was designed to be easy to use, while still being extremely flexible. If you just want a simple contact form, you can set one up with just a few clicks. For those of you who need something a bit more advanced, you can completely customize the plugin to fit your needs - whether it is 5 fields or 500. A non-WordPress version is also available. ReCaptcha support has also been added, as well as support for storing the data in a delimited file. More »

The WordPress plugin API provides a large number of action and filter hooks to make plugin creation easier. While the provided hooks cover just about everything you would need for plugin development, it can occasionally be useful to have a hook that can process the entire html output of WordPress. This article describes a method that can be used to create a ‘virtual’ hook which allows processing of everything between the end of the header section, and the footer of the theme, using the output buffering feature of PHP.

With the release of WordPress 2.3, there were several major changes to the database structure. Most notably was the new taxonomy schema, which replaced the categories, post2cat, and link2cat tables in favor of a new term based system with three new tables - terms, term_taxonomy, and term_relationships. While there are plenty of guides on the new structure, this is a simple visual guide to the relationships of these tables - specifically for category handling. This information is really only useful for those who are writing plugins or other code that interface with the database directly, and want a handy reminder of the table relationships. More »

This plugin uses the built-in scheduling feature of WordPress to periodically take a draft post and publish it. You can define the time between occurrences, and choose to have it publish the oldest draft each time, or a random draft. By default, it publishes drafts in any category, but you can define one, or multiple, categories for it to take the drafts from. More »
