Hi James,

Thanks again for you time.
There is obviously informations missing on my side, so please allows me to provide some details:

All of the following is for the admin backend only
• I’m editing an article, on which is attached a flexible content field.
• This flexible content, contains (among others) a gallery group of fields (I’m using the “clone” field type into my flexible content field for that).
• This gallery group of fields contains (among others), a repeater field named “image_size”
• This “image_size” repeater contains the select (image_reference) I want to hook and populate with the database value.

Here’s a draw:

So far, my code (ultra basic, still not working) is the following:

if (is_admin()){
	$fieldKey = 'field_5831de130046f';

	function my_acf_load_field($field){
		global $post;
		$db_value = get_field('image_size', $post->ID, false);
		return $field;
	}
	add_filter('acf/load_field/key=' . $fieldKey, 'my_acf_load_field', 10, 1);
}

First question: If I want to hook the ‘image_reference’ select, the $fieldKey should be the ‘image_reference’ key right?

Second question: what should be the field I’m asking for with get_field? If my hook (add_filter) is set on ‘image_reference’, I should have get_field(‘image_reference’)?

I’ve to admit I’m completely lost here…
Depending the get_field I’m doing (with nothing more than this action), even the “return $field” doesn’t work anymore.

I tried to contact you in private, but looks like it’s not possible.
If you want, you can try contacting me on iMessage (same nickname [at] mac.com) or Skype (same nickname).

Best regards.
