到debug a hook 查看相关的操作和筛选器。它们列在中$GLOBALS[\'wp_filter\'].

调试插件示例

<?php # -*- coding: utf-8 -*-
/**
 * Plugin Name: T5 Debug Hook
 * Description: Adds a list of registered filters and action for a hook. Call a page with <code>?hook=NAME</code> to see it.
 */

add_action( \'shutdown\', \'t5_debug_hook\' );

function t5_debug_hook()
{
    if ( ! isset ( $_GET[\'hook\'] ) or ! current_user_can( \'update_core\') )
    {
        return;
    }

    $f = $GLOBALS[\'wp_filter\'];

    if ( ! isset ( $f[ $_GET[\'hook\'] ] ) )
    {
        print \'Nothing found for \' . esc_html( $_GET[\'hook\'] );
        return;
    }

    print \'<pre>\' . esc_html( var_export( $f[ $_GET[\'hook\'] ], TRUE ) ) . \'</pre>\';
}

的样本输出example.com/?hook=wp_footer

array (
  20 => 
  array (
    \'wp_print_footer_scripts\' => 
    array (
      \'function\' => \'wp_print_footer_scripts\',
      \'accepted_args\' => 1,
    ),
  ),
  1000 => 
  array (
    \'wp_admin_bar_render\' => 
    array (
      \'function\' => \'wp_admin_bar_render\',
      \'accepted_args\' => 1,
    ),
  ),
)

现在，您可以停用单个操作和筛选器，直到找到最慢的操作和筛选器。

remove_action( \'wp_footer\', \'wp_admin_bar_render\', 1000 );

你的网站对我来说呈现得很好，所以我猜这是管理栏或是只为登录用户加载的脚本。
