I have the most current MB AIO. I want to connect a post to a product to get cart information to place on the post. I am using the POST field which in Bricks does return the product title and link, but I want the product ID to plug it into the cart.
If you use Meta Box helper function $post_id = rwmb_meta( 'post_field_id' ); it will return the post ID by default. Maybe the Bricks builder filters the value and returns the title and link for displaying in the frontend.
