Useful Plugins for WordPress Theme Developers

Many plugins are ready for download at the Word-Press Plugin Repository. Many plugins are no longer maintained and may only work with older versions of WordPress; and conversely, many newer plugins are developed exclusively Useful Plugins for Theme Developers.

Here are Thirteen plugins that I have found to be virtually indispensable for theme development: (Reference: )

1. Custom Query String


After installing it you will be able to set the number of posts (custom queries) for every single page on your website.

2. The Excerpt Reloaded


Based on the_excerpt, the_excerpt Reloaded, when a post does not contain an excerpt, displays the contents of the post (typically abbreviated), which can be customized on which HTML tags to allow, length of the excerpt (in words), “more…” link, and filtering type. The plugin’s function the_excerpt_reloaded() must be used in The Loop.

3. Theme Switcher

Allow users to switch which theme they use on your WordPress, WordPress MU, or BuddyPress site. Includes a widget for easily putting the theme-switcher as a list or dropdown in your sidebar.

4. Theme Test Drive

Theme Test Drive WordPress plugin allows you to safely test drive any theme on your blog as administrator, while visitors still use the default one. It happens completely transparently and they will not even notice you run a different theme for yourself. Best part is you can even set the testing theme options (if it has them) in the Admin panel while you are testing the theme.

8. Raw HTML

This plugin lets you use raw HTML or any other code in your posts. One way to use it is to wrap a part of your post in special tags (below) to prevent WordPress from converting newlines to HTML paragraphs, escaping apostrophes and so on. This is very useful if you need to add a CSS block or JavaScript to your post.
