我刚设置了一个自定义的帖子类型，主要是以下内容this tutorial.

我现在正在我的网站上设置东西，做了很多CSS修改之类的，每隔几分钟，帖子就会忘记自定义元框中的所有内容。

我确信我在add\\u action/update\\u post\\u meta部分中做了一些错误，但我不知道它是什么，因为我并不真正理解代码的全部功能。

无论如何，事情是这样的：

add_action(\'init\', \'portfolio_register\');

function portfolio_register() {

    $labels = array(
        \'name\' => _x(\'My Portfolio\', \'post type general name\'),
        \'singular_name\' => _x(\'Portfolio Item\', \'post type singular name\'),
        \'add_new\' => _x(\'Add New\', \'portfolio item\'),
        \'add_new_item\' => __(\'Add New Portfolio Item\'),
        \'edit_item\' => __(\'Edit Portfolio Item\'),
        \'new_item\' => __(\'New Portfolio Item\'),
        \'view_item\' => __(\'View Portfolio Item\'),
        \'search_items\' => __(\'Search Portfolio\'),
        \'not_found\' =>  __(\'Nothing found\'),
        \'not_found_in_trash\' => __(\'Nothing found in Trash\'),
        \'parent_item_colon\' => \'\'
    );

    $args = array(
        \'labels\' => $labels,
        \'public\' => true,
        \'publicly_queryable\' => true,
        \'show_ui\' => true,
        \'query_var\' => true,
        \'menu_icon\' => get_stylesheet_directory_uri() . \'/article16.png\',
        \'rewrite\' => true,
        \'capability_type\' => \'post\',
        \'hierarchical\' => false,
        \'menu_position\' => null,
        \'supports\' => array(\'title\',\'editor\',\'thumbnail\')
      ); 

    register_post_type( \'portfolio\' , $args );
}

register_taxonomy("portfolio_cat", array("portfolio"), array("hierarchical" => true, "label" => "Categories", "singular_label" => "Category", "rewrite" => true));
