Attach the uploaded media file to the post

I have found a code to automatically update media attachment to be attached to the current post it was uploaded to :

<?php

add_action('save_post', 'update_image_data');

function update_image_data($post_id){
    $images = get_post_meta($post_id, 'mg_projet_galerie_images', true);
    if(!empty($images)){
        foreach($images as $image){
            wp_update_post(array('ID' => $image, 'post_parent' => $post_id));
        }
    }
}
?>

It would be nice to have this feature natively. For example, in Bricks Builder you could query the medias attached to the current post this way : https://academy.bricksbuilder.io/article/query-loop/#media-query
At the moment, if medias are not attached to the post, then you can not query them without adding more custom code such as this one (it was given to me by Bricks support - replace with your own ID and custom field names) :

<?php 

add_filter( 'bricks/posts/query_vars', function( $query_vars, $settings, $element_id ) {

    if ( $element_id !== 'yeamho') return $query_vars;
        
    $gallery_images = (array) rwmb_meta( 'mg_projet_galerie_images', ['size' => 'full'] );
    $gallery_images_ids = array_keys($gallery_images);
    
    // if no gallery images, set empty string array
    $gallery_images_ids = count($gallery_images_ids) > 0 ? $gallery_images_ids : [''];
    
    $query_vars['post__in'] = $gallery_images_ids;

    return $query_vars;
}, 10, 3 );
?>

Hi,

Well, as of yesterday, it did not work. The Media Attachment is not attached to the current post it is uploaded to. At least, it does not show as attached to when displaying Media Library (in WP backend) as a list, where it should.

using the snippet I provided above, it does work nicely. But if the Media Attachment is removed from the custom field (Advanced Images), it does unfortunately not update the attachment to the post (by removing it).

There is still work to be done, hope MB can implement this all the way.
