Wordpress 3.5: own gallery with included images doesn't work

I figured it out: If you use a gallery with images, which are already uploaded to the media library, the gallery shortcode looks like [gallery ids=1,2,3], what means, that images are only linked (and not attached) to the gallery, so post_type=attachment doesn't work.

Now i'm using regular expressions to get the image IDs:

$post_content = $post->post_content;preg_match('/\[gallery.*ids=.(.*).\]/', $post_content, $ids);$array_id = explode(",", $ids[1]);

It's now possible to pull all the galleries or even a single gallery using the $post->ID and get_post_galleries(). Each gallery will contain the image id list in ids as well as a list of the image urls in src. The gallery object is basically the shortcode arguments so you have access to those as well.

if ( $galleries = get_post_galleries( $post->ID, false ) ) {    $defaults = array (        'orderby'    => 'menu_order ASC, ID ASC',        'id'         => $post->ID,        'itemtag'    => 'dl',        'icontag'    => 'dt',        'captiontag' => 'dd',        'columns'    => 3,        'size'       => 'full',        'link'       => 'file',        'ids'        => "",        'src'        => array (),    );    foreach ( $galleries as $gallery ) {        // defaults        $args = wp_parse_args( $gallery, $defaults );        // image ids        $args[ 'ids' ] = explode( ',', $args[ 'ids' ] );        // image urls        $images = $args[ 'src' ];    }}
