It uses the following parameters: type defines the type of the filter. Valid values are "pre", "post", "output" and "variable". callback defines the PHP callback. it can be either: 1.A string containing the function name 2.An array of the form array(&$object, $method) with &$object being a reference to an object and $method being a string containing the method-name 3.An array of the form array($class, $method) with $class being the class name and $method being a method of the class. 本函數在模板中動態地注冊過濾器。其參數如下： “type”定義過濾器的類型，其值為下列之一：“pre”、“post”、“output”和“variable”； “callback”為定義的php回調函數，其類型為下列之一： 1、包含函數名的字符串； 2、格式為(&$object, $method)的數組，其中，&$object為引用對象，$method為包含方法名的字符串； 3、格式為($class, $method)的數組，其中，$class為類名，$method為類中的方法。 <table width="80%" border="0" cellpadding="2" cellspacing="2" class="note"><caption> 技術提示 </caption> <tr><td>Technical Note<br/> If the chosen function callback is of the form array(&$object, $method), only one instance of the same class and with the same $method can be registered. The latest registered function callback will be used in such a scenario. <br/> 如果選擇array(&$object, $method)格式的回調函數，帶相同方法（$method）的相同類，只能注冊一個實例。在這種情況下將使用最后注冊的回調函數。</td> </tr></table> 譯注 | 預過濾器（Prefilters）、后過濾器（Postfilters）和輸出過濾器（Output Fiters）都可以使用本方法注冊。 | |-----| A prefilter runs through the template source before it gets compiled. See template prefilters for more information on how to setup a prefiltering function. A postfilter runs through the template code after it was compiled to PHP. See template postfilters for more information on how to setup a postfiltering function. A outputfilter operates on a template's output before it is displayed.
