WordPress:Function Reference/remove filter

描述

This function removes a function attached to a specified filter hook. This method can be used to remove default functions attached to a specific filter hook and possibly replace them with a substitute. See also remove_action(), add_filter() and add_action().

这个函数移除了附加在某个filter hook上的函数。这种方法可以用来移除附加在某个filter hook上的默认函数，同时可以将这些默认函数替换为另一个函数。也看看remove_action(), add_filter() 和 add_action()。

Important: To remove a hook, the $function_to_remove and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.

重点:要移除hook，添加hook时，$function_to_remove和$priority参数必须匹配。这也同样适用于filters和actions。移除操作失败，不会给通知。

例子

This function is identical to the remove_action() function.

<?php remove_filter($tag, $function_to_remove, $priority, $accepted_args); ?>

这个函数与remove_action()函数是相同的。 <?php remove_filter($tag, $function_to_remove, $priority, $accepted_args); ?>
