register_prefilter() — dynamically register prefilters
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
$method being a method of the class.
If the chosen function callback is of the form
array(&$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.
