The WordPress Hook Sniffer plugin is a tool for plugin developers that helps determine the sequence in which action and filter functions are fired.
As mentioned in the Installation section of this readme file, this plugin should not be installed on an active WordPress-based site (a production site). There will be
no support for broken production sites. You have been warned! Of course, you can technically install this plugin on your production site if you wish to provide your site's users with a screen full of text output that will confuse them!
If you've selected
To Screen in the Output Location settings section, then look for the output to begin just below your theme's footer. If you've selected the
To File output option, then look for the text file "wp-hook-sniff.txt" in the "hook-sniff-report" folder of the wordpress-hook-sniffer directory.
To appreciate the value of this plugin, you must first have an understanding of WordPress action hooks and filter hooks. Also, experience in tying into hooks and modifying function output via action functions and filter functions is desirable. Once you have a solid working knowledge of WordPress' Plugin API, you should then read my article, WordPress Hooks, Barbs, and Snags.
