# register_prefilter()

register_prefilter() -- dynamically register prefilters

## Description

void register_prefilter ( mixed function)

Use this to dynamically register prefilters to run templates through before they are compiled. See template prefilters for more information on how to setup a prefiltering function.

The php-function callback `function` can be either:

- A string containing the function `name`

- An array of the form `array(&$object, $method)` with `&$object` being a reference to an object and `$method` being a string containing the method-name

- An array of the form `array(&$class, $method)` with `$class` being the class name and `$method` being a method of the class.

See also `unregister_prefilter()`, `register_postfilter()`, `register_ouputfilter()`, `load_filter()`, `$autoload_filters` and template output filters section.
