Show the Intro to Password Protected Posts in WordPress

This is a small hack for WordPress that allows you to show the first part of password protected posts. It will display the content you have before the ‘more’ tag, followed by the standard password box. I wrote this up for a member of the WordPress forum, and I thought I would share it here. Update: Instructions are now provided for WordPress 2.2 More »

Change Default Thumbnail Size in WordPress

WordPress 2.5 and later include a built-in option to change the size of thumbnails, but for those of you out there using an older version, it is quiet easy to change. It just requires modification of one WordPress file. When WordPress 2.1 was released, it changed the way this was done, and once again with the release of WordPress 2.3, so I have included instructions below for multiple versions. More »

WordPress Search Form without Search Button

This article explains a method for displaying a WordPress search form without a search button. The user simply enters they text they would like to search for, and hits enter. While this is easy to do with the use of a hidden submit button, this method also allows for the use of a default message in the search box (such as “Enter your search”), which keeps you from having to display a label next to the form explaining what it is for. This default message automatically clears when the user clicks to start typing, and puts itself back if the user clicks away. This allows you to have a search form that looks nice and clean, and is still just as functional. More »

Specify the user level needed to skip comment moderation in WordPress

This simple WordPress hack allows you to specify the minimum user level needed to post comments without moderation. By default, WordPress allows administrators (and the author of the post) to skip moderation checks when posting comments, but it is easy to adjust this so that you can choose the user level yourself. This can be useful for those of you who have strict comment moderation enabled (manual comment approval), as it allows you to let registered users of your site post immediately without having to wait for approval.

Prevent author impersonation in WordPress comments

This modification to WordPress prevents unregistered comment authors from using the names or email addresses of the registered authors on your site. It does this by first checking to see if the comment author is logged in. If they are not, it compares their name and email address to the registered author data. If there is a match, the comment is blocked and a custom message is displayed. The name and email address comparison is case-insensitive. More »

WordPress Hook for Entire Page Using Output Buffering

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.

WordPress 2.3+ Database Structure for Categories

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 »
