如何检查是哪个钩子触发了对函数的调用？

我有一种情况，我有一个连接到多个自定义挂钩的函数。如何检入回调函数哪个自定义挂钩触发了调用？

否则代码中的问题将是

add_action(\'my_test_hook_1\',\'my_test_callback_function\');
add_action(\'my_test_hook_2\',\'my_test_callback_function\');
add_action(\'my_test_hook_3\',\'my_test_callback_function\');
add_action(\'my_test_hook_4\',\'my_test_callback_function\');

function my_test_callback_function(){

    $called_action_hook = ; //Some magic code that will return current called action the hook

    echo "This function is called by action: " . $called_action_hook ;

}

add_action(\'my_test_hook_1\',\'my_test_callback_function\'); add_action(\'my_test_hook_2\',\'my_test_callback_function\'); add_action(\'my_test_hook_3\',\'my_test_callback_function\'); add_action(\'my_test_hook_4\',\'my_test_callback_function\'); function my_test_callback_function(){ $called_action_hook = current_filter(); // ***The magic code that will return the last called action echo "This function is called by action: " . $called_action_hook ; }

add_action(\'my_test_hook_1\',\'my_test_callback_function\'); add_action(\'my_test_hook_2\',\'my_test_callback_function\'); add_action(\'my_test_hook_3\',\'my_test_callback_function\'); add_action(\'my_test_hook_4\',\'my_test_callback_function\'); function my_test_callback_function( $called_action_hook ){ echo "This function is called by action: " . $called_action_hook ; } do_action(\'my_test_hook_1\',\'my_test_hook_1\'); do_action(\'my_test_hook_2\',\'my_test_hook_2\'); etc.

Conditional action hooks

我正在开发一个使用AJAX的插件，但我在控制代码流方面遇到了困难。我想在运行条件后挂接函数。我的钩子在控制结构内部添加时不会启动，但在外部会启动。我还有一个触发AJAX请求的事件，这只能在用户点击触发事件后，在加载所有DOM之后发生。AJAX请求告诉PHP函数设置cookie。它设置了cookie，但在阅读关于cookie的PHP文档时，我发现它们只能在发送任何输出后设置，但我还是做到了这一点？我读过WordPress初始化序列，但这并没有帮助我解决这个问题。这是我的密码：add_action(\'wp_
