Question

我尝试复制并粘贴此代码段并更改ID，但由于某种原因，它正在破坏我的主题。如果有人能提出一些有用的建议，我感激不尽！谢谢！

使用此代码创建新的幻灯片类型..

    function slider(){
    $labels = array( 'name' => 'Slider', 'singular_name' => 'Slider', 'add_new' => 'Add New', 'add_new_item' => 'Add New Slider', 'edit_item' => 'Edit Slider', 'new_item' => 'New Slider', 'all_items' => 'All Sliders', 'view_item' => 'View Slider', 'search_items' => 'Search Sliders', 'not_found' =>  'No Sliders found', 'not_found_in_trash' => 'No Sliders found in Trash', 'parent_item_colon' => '', 'menu_name' => 'Sliders' );

    $args = array( 'labels' => $labels, 'public' => true, 'publicly_queryable' => true, 'show_ui' => true,  'show_in_menu' => true, 'query_var' => true, 'rewrite' => array( 'slug' => 'slider' ), 'capability_type' => 'post', 'has_archive' => true, 'hierarchical' => false,'menu_position' => null,'supports' => array( 'title', 'thumbnail', 'excerpt' ) ); 
    register_post_type( 'slider', $args );

    $labels = array( 'name' => 'News', 'singular_name' => 'News', 'add_new' => 'Add New', 'add_new_item' => 'Add New News', 'edit_item' => 'Edit News', 'new_item' => 'New News', 'all_items' => 'All Newss', 'view_item' => 'View News', 'search_items' => 'Search Newss', 'not_found' =>  'No Newss found', 'not_found_in_trash' => 'No Newss found in Trash', 'parent_item_colon' => '', 'menu_name' => 'Newss' );

    $args = array( 'labels' => $labels, 'public' => true, 'publicly_queryable' => true, 'show_ui' => true,  'show_in_menu' => true, 'query_var' => true, 'rewrite' => array( 'slug' => 'news' ), 'capability_type' => 'post', 'has_archive' => true, 'hierarchical' => false,'menu_position' => null ); 
    register_post_type( 'news', $args );
    }
add_action('init','slider');

如何在WP上创建此幻灯片的新实例？
