Ok James,
I think I made it, but doing my own database request:
if (is_admin()){
$fieldKey = 'field_5831de3000470'; // image_reference
function my_acf_load_field($field){
global $post;
global $wpdb;
$query = "SELECT * FROM 'myDatabaseName'.'wp_postmeta' WHERE 'meta_key' LIKE 'taz_shortcodes_%_image_size_%_image_reference' AND 'post_id' = $post->ID";
$rows = $wpdb->get_results($query);
$field['choices'] = array();
foreach ($rows as $row) {
$field['choices'][$row->meta_value] = $row->meta_value;
}
return $field;
}
add_filter('acf/load_field/key=' . $fieldKey, 'my_acf_load_field', 10, 1);
}
Let me know what you’d have done differently.
Thanks in advance.
