WordPress 2.x Filter List for Plugin and Theme Developers

WordPress Filters are functions through which data flows or is changed. They’re good for making on-the-fly changes to data (like adding acronyms to certain words). An exhaustive list of all filters available in WordPress 2.x along with annotations (where available) are provided.

Note: Filters are sitting between the database and the browser. Everything that flows from the database to the browser has to pass through a filter. By adding a filter you can change what the user sees without changing the content of your database. On the other hand, other filters can preprocess the inputs before their storage in your database.

The WordPress filters are displayed alphabetically below. Please click on appropriate (guess if required) alphabet to view all filters starting with that alphabet.

Note: Additionally there are few template filters which apply filters to Templates as described here.
