这取决于功能myAction() 正在做。

您的订单如下：

插入定义动作挂钩do_action( \'bp_members_delete_account_after_submit\' );

add_action( \'bp_members_delete_account_after_submit\',
            \'action_bp_members_delete_account_after_submit\' );

功能action_bp_members_delete_account_after_submit() 然后添加一个名为\'myAction\' 并将两个参数作为字符串传递给它\'arg1\' 和\'arg2\'.

但是在上面的代码中没有什么可以“发生”的，除非您有一个连接到myAction.

add_action( \'myAction\', \'my_function\', 10, 2 );

function my_function( $first_arg, $second_arg ) {
     //here, $first_arg would be literally equal to text \'arg1\'
     // $second_arg would be literally equal to the text \'arg2\'

     //you would do stuff here
}

当然，您可以跳过其中的一部分，在action_bp_members_delete_account_after_submit() 通过以下方式实现功能：

function action_bp_members_delete_account_after_submit() {
    //you would do stuff here, 
    //no need to make another hook if you are not going to hook things to it
}
