I found this thread:
https://toolset.com/forums/topic/create-wp-gallery-from-multiple-image-field/

and am trying to do the same thing (Create gallery out of a repeating image field), but cannot get it to work.

I have a repeating image field named "Image Gallery" with the slug 'partner-image-gallery'

I placed this in functions.php

add_shortcode( 'gallery_from_image_fields', function( $atts ){
 
    global $wpdb;
 
    $postid = $atts['postid'];
    $slug = 'wpcf-partner-image-gallery' . $atts['slug'];
 
 
    // Retrieve image field urls
    $images = (array) get_post_meta( $postid, $slug, false);
 
    $ids = array();
    // Convert the urls to post ids for the images
    foreach ($images as $image) {
 
        $attachment = $wpdb->get_col( $wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE guid='%s';", $image ) ); 
        $ids[] = $attachment[0];
    }
 
    $ids_list = join( ',', $ids );
 
    $gallery = '[gallery ids="' . $ids_list . '"]';
 
    $out = do_shortcode( $gallery );
 
    return $out;
});

and then this in my page template

[gallery_from_image_fields postid='[wpv-post-id]' slug='partner-image-gallery']

But I can't get it to work. Any idea what I may be doing wrong?

Thanks so much!!

Dear staceyz,

I assume the custom image filed "partner-image-gallery" is created with Types plugin, Types will pre-pend "wpcf-" before the field slug, please try this, edit this line from:

    $slug = 'wpcf-partner-image-gallery' . $atts['slug'];

To:

    $slug = 'wpcf-' . $atts['slug'];

And test again
