Display a Custom Post Type’s Media Library Inline

Are you looking for a way to display a custom post type’s media library inline? While there’s probably a plugin for this, we have created a quick code snippet that you can use to display a custom post type’s media library inline in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

  define('MY_POST_TYPE', 'my');
  define('MY_POST_SLUG', 'gallery');

  function my_register_post_type () {
  	$args = array (
  		'label' => 'Gallery',
  		'supports' => array( 'title', 'excerpt','thumbnail' ),
  		'register_meta_box_cb' => 'my_meta_box_cb',
  		'show_ui' => true,
  		'query_var' => true
  	);
  	register_post_type( MY_POST_TYPE , $args );
  }
  add_action( 'init', 'my_register_post_type' );

  function my_meta_box_cb () {
  	add_meta_box( MY_POST_TYPE . '_details' , 'Media Library', 'my_meta_box_details', MY_POST_TYPE, 'normal', 'high' );
  }

  function my_meta_box_details () {
  	global $post;
    $post_ID = $post->ID; 
  	printf( "<iframe frameborder='0' src=' %s ' style='width: 100%%; height: 400px;'> </iframe>", get_upload_iframe_src('media') );
  }
