我相信这回答了你的两个问题（这和this), 看看My Meta box class 它允许在自定义元数据库中添加任何类型的字段。

一旦你上了这门课，你需要做的就是这样：

//include the main class file
require_once("meta-box-class/my-meta-box-class.php");
// configure your meta box
$config = array(
    \'id\' => \'event_review_box\',             // meta box id, unique per meta box
    \'title\' => \'Event Review\',          // meta box title
    \'pages\' => array(\'event\'),          // post types, assuming that your post type name is event
    \'context\' => \'normal\',              // where the meta box appear: normal (default), advanced, side; optional
    \'priority\' => \'high\',               // order of meta box: high (default), low; optional
    \'fields\' => array(),                // list of meta fields (can be added by field arrays) or using the class\'s functions
    \'local_images\' => false,            // Use local or hosted images (meta box images for add/remove)
    \'use_with_theme\' => false           //change path if used with theme set to true, false for a plugin or anything else for a custom path(default false).
);
// Initiate your meta box
$my_meta2 = new AT_Meta_Box($config);
//Add fields to your meta box
$my_meta2->addWysiwyg(\'wysiwyg_field_id\',array(\'name\'=> \'Event Recap\'));
//Finish Meta Box Deceleration
$my_meta2->Finish();

// configure your meta box
$config = array(
    \'id\' => \'event_date_box\',           // meta box id, unique per meta box
    \'title\' => \'Event date\',            // meta box title
    \'pages\' => array(\'event\'),          // post types, assuming that your post type name is event
    \'context\' => \'normal\',              // where the meta box appear: normal (default), advanced, side; optional
    \'priority\' => \'high\',               // order of meta box: high (default), low; optional
    \'fields\' => array(),                // list of meta fields (can be added by field arrays) or using the class\'s functions
    \'local_images\' => false,            // Use local or hosted images (meta box images for add/remove)
    \'use_with_theme\' => false           //change path if used with theme set to true, false for a plugin or anything else for a custom path(default false).
);
// Initiate your meta box
$my_meta = new AT_Meta_Box($config);
//Add fields to your meta box
$my_meta->addDate(\'date_field_id\',array(\'name\'=> \'Event Date \'));
//Finish Meta Box Deceleration
$my_meta->Finish();
