以下代码将所有注册的WP自定义帖子类型（仅针对管理员）列为管理员仪表板小部件。记住，如果“Wordpress自定义帖子类型”小部件被隐藏，请启用它。

默认情况下，$cpt\\u remove变量包含我不想显示的帖子类型的名称，您可以添加更多名称以保持列表简短。

Use this in your theme\'s functions.php or within a plugin:

add_action(\'wp_dashboard_setup\', \'siv_admin_listall_cpts\');

function siv_admin_listall_cpts() {

    if( current_user_can(\'manage_options\') ) {
        wp_add_dashboard_widget(
                     \'siv_list_cpts\',                        // Widget slug.
                     \'Wordpress Custom Post Types\',         // Title.
                     \'siv_show_all_cpts\' // Display function.
            );  
    }
}
add_action( \'wp_dashboard_setup\', \'siv_admin_listall_cpts\' );


// Create the function to output the contents of our Dashboard Widget.   
function siv_show_all_cpts() {
    global $wp_post_types;
    $posttypes = array_keys( $wp_post_types );

    // Remove unwanted if any
    $cpt_remove = array("attachment","nav_menu_item","customize_changeset","revision");


    foreach ( $posttypes as $post_type ) {
        if ( in_array($post_type, $cpt_remove) ) continue;
        echo \'<ul>\';
        echo \'<li>\'.$post_type.\'</li>\';
        echo \'</ul>\';
    }
}
