我正在制作一个自定义滑块，管理员可以从后端添加滑块图像。我是在自定义帖子类型的帮助下完成的。

function.php

// Custom Post types for Feature project on home page 
   add_action(\'init\', \'create_feature\');
     function create_feature() {
       $feature_args = array(
          \'labels\' => array(
           \'name\' => __( \'Feature Project\' ),
           \'singular_name\' => __( \'Feature Project\' ),
           \'add_new\' => __( \'Add New Feature Project\' ),
           \'add_new_item\' => __( \'Add New Feature Project\' ),
           \'edit_item\' => __( \'Edit Feature Project\' ),
           \'new_item\' => __( \'Add New Feature Project\' ),
           \'view_item\' => __( \'View Feature Project\' ),
           \'search_items\' => __( \'Search Feature Project\' ),
           \'not_found\' => __( \'No feature project found\' ),
           \'not_found_in_trash\' => __( \'No feature project found in trash\' )
         ),
       \'public\' => true,
       \'show_ui\' => true,
       \'capability_type\' => \'post\',
       \'hierarchical\' => false,
       \'rewrite\' => true,
       \'menu_position\' => 20,
       \'supports\' => array(\'title\', \'editor\', \'thumbnail\')
     );
  register_post_type(\'feature\',$feature_args);
}
add_filter("manage_feature_edit_columns", "feature_edit_columns");

function feature_edit_columns($feature_columns){
   $feature_columns = array(
      "cb" => "<input type=\\"checkbox\\" />",
      "id" => "ID",
      "title" => "Title",
   );
  return $feature_columns;
}



add_action( \'add_meta_boxes\', \'cd_meta_box_add\' );
function cd_meta_box_add()
{
    add_meta_box( \'my-meta-box-id\', \'Link to Project\', \'cd_meta_box_cb\', \'feature\', \'normal\', \'high\' );
}

function cd_meta_box_cb( $post )
{
    $url = get_post_meta($post->ID, \'url\', true);
    wp_nonce_field( \'my_meta_box_nonce\', \'meta_box_nonce\' ); ?>

    <p>
        <label for="url">Project url</label>
        <input type="text" name="url" id="url" value="<?php echo $url; ?>" style="width:350px" />
    </p>

    <?php   
}

add_action( \'save_post\', \'cd_meta_box_save\' );
function cd_meta_box_save( $post_id )
{
    // Bail if we\'re doing an auto save
    if( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE ) return;

    // if our nonce isn\'t there, or we can\'t verify it, bail
    if( !isset( $_POST[\'meta_box_nonce\'] ) || !wp_verify_nonce( $_POST[\'meta_box_nonce\'], \'my_meta_box_nonce\' ) ) return;

    // if our current user can\'t edit this post, bail
    if( !current_user_can( \'edit_post\' ) ) return;

    // now we can actually save the data
    $allowed = array( 
        \'a\' => array( // on allow a tags
            \'href\' => array() // and those anchors can only have href attribute
        )
    );

    // Probably a good idea to make sure your data is set
    if( isset( $_POST[\'url\'] ) )
        update_post_meta( $post_id, \'url\', wp_kses( $_POST[\'url\'], $allowed ) );
}

给，我想要ID 之后Title. 这样管理员就可以从中设置幻灯片图像顺序ID.

谁能告诉我怎么做？
