知道哪一个文件调用过滤器或某个操作不可能运行代码，您必须搜索并阅读源代码或使用一些文档。

有不同的插件可以帮助您调试页面中触发的钩子，搜索codex和/或Google。

不过，要想快速了解情况，请在您的functions.php

class MyTracker {

  static $hooks;

  static function track_hooks( ) {
    $filter = current_filter();
    if ( ! empty($GLOBALS[\'wp_filter\'][$filter]) ) {
      foreach ( $GLOBALS[\'wp_filter\'][$filter] as $priority => $tag_hooks ) {
        foreach ( $tag_hooks as $hook ) {
          if ( is_array($hook[\'function\']) )  {
            if ( is_object($hook[\'function\'][0]) ) {
              $func = get_class($hook[\'function\'][0]) . \'->\' . $hook[\'function\'][1];
            } elseif ( is_string($hook[\'function\'][0]) ) {
              $func = $hook[\'function\'][0] . \'::\' . $hook[\'function\'][1];
            }
          } elseif( $hook[\'function\'] instanceof Closure ) {
            $func = \'a closure\';
          } elseif( is_string($hook[\'function\']) ) {
            $func = $hook[\'function\'];
          }
          self::$hooks[] = \'On hook <b>"\' . $filter . \'"</b> run <b>\'. $func . \'</b> at priority \' . $priority;
        }
      }
    }
  }

}

add_action( \'all\', array(\'MyTracker\', \'track_hooks\') );

add_action( \'shutdown\', function() {
    echo implode( \'<br />\', MyTracker::$hooks );
}, 9999);
