如何在WP上創建此幻燈片的新實例？

Question

我試圖複製並粘貼此代碼段並更改ID，但由於某種原因它破壞了我的主題。如果有人能提供一些有用的建議，我將不勝感激！謝謝！

/*幻燈片*/

$prefix = 'sgt_'; 

$meta_box = array(
    'id' => 'slide', 
    'title' => 'Slideshow Options',

    'fields' => array(
     array(

      'id' => $prefix . 'slide', 
      'type' => 'checkbox' 
     ) 
    )

add_action('admin_menu', 'sight_add_box'); 


// Add meta box 
function sight_add_box() { 
    global $meta_box; 

    add_meta_box($meta_box['id'], $meta_box['title'], 'sight_show_box', $meta_box['page'], $meta_box['context'], $meta_box['priority']);

// Callback function to show fields in meta box

    echo '<input type="hidden" name="sight_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />'; 

    echo '<table class="form-table">'; 

    foreach ($meta_box['fields'] as $field) { 
     // get current post meta data 
     $meta = get_post_meta($post->ID, $field['id'], true);

使用此代碼來創建新的幻燈片後類型..

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');
