未显示自定义类型的元框

这是我的自定义类型邮编。我想在那里添加元框。。。

function events_cust(){
      $label = array(
            \'name\' => _x(\'Events\'),
            \'singular_name\' => _x(\'events\'),
            \'menu_name\'  => __(\'Events\'),
            \'add_new\' => __(\'Add Event\'),
            \'add_new_item\' => __ (\'Add New Event\'),
            \'all_item\' => __(\'All Event\'),
            \'edit_item\' => __(\'Edit Event\'),
            \'new_item\' => __(\'New Event\'),
            \'view_item\' => __(\'View Event\'),
            \'update_item\' => __(\'update Event\'),
            \'search_item\' => __(\'Search Event\')
            );
            $attr = array(
            \'label\' => __(\'Events\'),
            \'description\' => __(\'Event\'),
            \'labels\' => $label,
            \'supports\'  => array(\'title\',\'editor\',\'thumbnail\'),
            \'taxonomies\' => array(\'genres\'),
            \'hiecrarhical\' => false,
            \'public\' => true,
            \'show_ui\' => true,
            \'show_in_menu\' => true,
            \'show_in_adim_bar\' => true,
            \'menu_position\'       => 5,
   \'can_export\'          => true,
   \'has_archive\'         => true,
   \'exclude_from_search\' => false,
   \'publicly_queryable\'  => true,
   \'capability_type\'     => \'post\',
            );
            register_post_type(\'events-lists\',$attr);
      }
      add_action( \'init\', \'events_cust\', 0 );

   add_action(\'add_meta_boxes\',\'create_events_metaboxes\');
   function create_events_metaboxes(){
      add_meta_box(\'events-meta-box\',\'Events Details\',\'show_events_metaboxes\',\'events-lists\',\'normal\',\'hight\');
   }

   function show_events_metaboxes(){
    echo \'Hello Meta box\';
   }

我们怎么了。

add_action(\'add_meta_boxes\',\'create_events_metaboxes\'); function create_events_metaboxes() { add_meta_box(\'events-meta-box\',\'Events Details\',\'show_events_metaboxes\',\'events-lists\'); } function show_events_metaboxes($post){ echo \'Hello Meta box\'; }

function event_custom_meta_boxes( $post_type, $post ) { add_meta_box( \'my-meta-box\', __( \'My Meta Box\' ), \'render_my_meta_box\', \'post\', //post type, event, product etc. \'normal\', \'default\' ); } add_action( \'add_meta_boxes\', \'event_custom_meta_boxes\', 10, 2 ); function render_my_meta_box(){ echo "Hello World!"; }
