Name
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$method
being a string containing the method-nameAn array of the form
array($class, $method)
with$class
being the class name and$method
being a method of the class.
Technical Note
If the chosen function
callback is of the form
array(&$object, $method)
, only one instance of the
same class and with the same $method
can be registered. The
latest registered function
callback will be used in
such a scenario.
