Hi. I am trying to add my own Carousel to the Single Products. Ideally, I would like to display the Images selected under “Product Gallery” (meta key = _product_image_gallery). I am having a most difficult time doing this.
WooCommerce appears to be storing the images as IDs, but the GenerateBlocks Query Block v2 does not seem to enumerate through those IDs. Of course, I need the URLs – but first just prove out the IDs.
I have seen several forum posts here on a similar topic and George typically responds with some flavor of shortcode. I really do not want to use a shortcode – it is important for me to use the GenerateBlocks GUI to style instead of writing CSS for this.
I have been debugging this all day using hooks like render_block or generateblocks_query_loop_args trying to find a solution. Any ideas?

I put together a hacky workaround that hijacks the Query Block when Query Type is set to ‘Post Query’ (does not work with the desired ‘Post Meta’).
The filter I used is ‘generateblocks_query_wp_query_args’. I look at the classes associated with the Query Block to isolate the hijacking. Ultimately, I set $query_args[‘post__in’] to the list of IDs stored in the ‘_product_image_gallery’ Post Meta.
At this point, the Loop Item is actually being hit with something and I can largely proceed as I would expect using a GB Query Block.
Hope this helps someone.
If the GB team has any better ideas, please share. This is the best I could figure out after almost two days.

Hi there,
Your workaround is actually the right general approach here.
The Post Meta query type expects the meta value to be an actual array. WooCommerce stores
_product_image_galleryas a comma-separated string of attachment IDs, so the Query block can’t loop through it directly.
