Add personal note. Only visible to administrators

Set Settings in PHP

It is possible to set this setting in PHP using the acf/load_field_group hook. Note that this hook is used everywhere, including in ACF admin and tools screen. Usage example:

add_filter('acf/load_field_group', 'my_acf_field_group');
function my_acf_field_group($field_group){
    
    // Target a specific key
    if($field_group['key'] !== 'group_5f20935b9a777')
        return $field_group;
    
    // Settings
    $field_group['acfe_note'] = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.';
    
    // Return
    return $field_group;
    
}

Retrieve Settings

The note is saved in the Field Group array, under acfe_note key. It can be retrieved using acf_get_field_group(). Usage example:

$field_group = acf_get_field_group('group_5f20935b9a777');
