Filter all fields in field group?

We have a field group with a number of regular text fields. Data will be imported into these fields from an outside source, so the fields are just for viewing the information and not editing.

I know you can filter a single field to be read-only with this which works fine:

function my_acf_load_field( $field ) {
	$field['disabled'] = 1;
	return $field;
}
add_action('acf/load_field/name=field_name', 'my_acf_load_field');

But, is there any way to filter all of the fields in a field group the same way? If we have 20 fields in a group that need to be read-only, is there any way to set them all as read-only that doesn’t involve 20 lines of add_action hooks?

Thanks!

You may be able to use the field parent and check for the group, but I’m not sure

I would also use prepare_field, not load_field

function my_acf_load_field( $field ) {
  if ($field['parent'] == 'group_XXXXXXXXX') {
	$field['disabled'] = 1;
   }
	return $field;
}
add_action('acf/prepare_field', 'my_acf_load_field');

Thanks, John!

I had to modify this a little bit, but it seems like it does the trick. I found that if I didn’t look for a parent value first, things went a little haywire in different spots – for example, when trying to create a new field group.

Updating to this seems to be doing the trick in my quick test:

function my_acf_load_field( $field ) {

	// If no parent is found, everything kind of breaks.
	if ( ! $field['parent'] ) {
		return $field;
	}

	// Match only the key of the group we want to change.
	if ( 'group_XXXXXXXXX' == $field['parent'] ) {
		$field['disabled'] = 1;
	}

	return $field;
}
add_action( 'acf/prepare_field', 'my_acf_load_field' );

Thanks again for the suggestion!

Yes, I forgot about flex fields. Field in a flex field do not have ‘parent’ they have ‘parent_layout’ or some such thing.

you can still to it in a single if like this

if ( !empty$field['parent'] &&  'group_XXXXXXXXX' == $field['parent'] ) {

Just dropping a big thank you because this is EXACTLY what I needed to solve.

Thanks!
