Есть подобный код, который добавляет галерею к стандартным постам вордпресс, но как вывести результат того что он сохраняет?
function add_gallery(){
add_meta_box( 'catalog-product-images', __( 'Gallery', 'site_name' ), 'metabox_galler', 'post', 'side', 'low' ); //Тип поста post или images
}
add_action('add_meta_boxes', 'add_gallery');
function metabox_galler($post){ ?>
<div id="images_container">
<ul class="images">
<?php global $post;
if ( metadata_exists( 'post', $post->ID, '_image_gallery' ) ) {//Тип поста post или images
$image_gallery = get_post_meta( $post->ID, '_image_gallery', true );
} else {
$attachment_ids = get_posts( 'post_parent=' . $post->ID . '&numberposts=-1&post_type=attachment&orderby=menu_order&order=ASC&post_mime_type=image&fields=ids&meta_value=0' );
$attachment_ids = array_diff( $attachment_ids, array( get_post_thumbnail_id() ) );
$image_gallery = implode( ',', $attachment_ids );
}
$attachments = array_filter( explode( ',', $image_gallery ) );
if ( $attachments ) {
foreach ( $attachments as $attachment_id ) {
echo '<li class="image" data-attachment_id="' . esc_attr( $attachment_id ) . '">
' . wp_get_attachment_image( $attachment_id, 'thumbnail' ) . '
<ul class="actions">
<li><a href="#" class="delete tips" data-tip="' . __( 'Delete image', 'site_name' ) . '">' . __( 'Delete', 'site_name' ) . '</a></li>
</ul>
</li>';
}
}
?>
</ul>
<input type="hidden" id="image_gallery" name="image_gallery" value="<?php echo esc_attr( $image_gallery ); ?>" />
</div>
<p class="add_images hide-if-no-js">
