WordPress Hooks Search Tool

This tool scans all the PHP files in a directory you specify and lists out the Actions (from do_action) and Filters (from apply_filters) defined in these files. To search all files and subdirectories leave the Search in field empty. You may also specify a keyword to search for in the hook name.
