我正在开发一个小插件，其中一部分需要向所有自定义帖子类型添加几个元框。我尝试过以各种方式循环使用自定义端口类型的数组，但我不断遇到错误，我已经调用了add\\u meta\\u box等函数。下面的脚本是我的最新成果，它没有保存最后三个元框（仅第一个）中的值。

我真的想缩小这个尺寸。我正在使用一个类，根据我在网络图茨插件课程上学到的一些东西。它在其他方面还可以，但PHP不是我的强项，所以我被卡住了！是否有人可以帮助我循环或将自定义帖子类型的数组传递给函数add\\u meta\\u box？

这是相关脚本的一部分，对不起，这是一个很大的。。

//meta boxes...
    public function meta_boxes(){
    //load the array into a var
    $all_post_types = $this->post_types;

        $just_trades = array();
        foreach($all_post_types as $trade){
            $just_trades[] = $trade[\'post_type_name\'];  
        }
        //call the action 
        add_action(\'add_meta_boxes\',\'make_meta_box\');
        function make_meta_box(){
        //make array of all meta boxes we want to show..

        add_meta_box(\'landline\',\'Landline Phone Number\',\'landline_function\',$just_trades);//id, UI, the function, what page it shows on
        add_meta_box(\'mobile\',\'Mobile Phone Number\',\'mobile_function\',$just_trades);//id, UI, the function, what page it shows on
        add_meta_box(\'email\',\'Email Address\',\'email_function\',$just_trades);//id, UI, the function, what page it shows on
        add_meta_box(\'website\',\'Website URL\',\'website_function\',$just_trades);//id, UI, the function, what page it shows on
