Smarty成員方法:registerFilter()

• type defines the type of the filter. Valid values are "pre", "post", "output" and "variable".

• callback defines the PHP callback. it 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.

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.
