I have a site where I created a page that takes the gallery images from a post and puts them into a slider.
I used the following code:
// gets the gallery info $gallery = get_post_gallery( $post->ID, false ); // makes an array of image ids $ids = explode ( ",", $gallery['ids'] );
Then I inserted the images using wp_get_attachment_image().
Unfortunately, with WP 5.0 and Gutenberg, get_post_gallery no longer works with newly added content. It seems that get_post_gallery used a shortcode that no longer works with Gutenberg.
I am still getting up to speed on Gutenberg and the block system. Until I understand that all better, I was wondering if anyone has any advice on how to get the image ids from a gallery in Gutenberg?
