WordPress Code Snippets

A collection of WordPress PHP snippets. Every page documents one snippet: what it does, its version, its type, and its status.

The snippets were originally written for WP Codebox, but each one works the same as a mu-plugin, a plugin, or an entry in any snippet manager. Start with installing a snippet if you are new here, and read the header contract if you are adding one.

50 snippets in 21 categories. Each page lists the version, type and status, and links to the source file.
