Awesome thank you! Using the code like this did the trick –
add_action('current_screen', 'maybe_add_filters');
function maybe_add_filters() {
if (function_exists('get_current_screen')) {
$screen = get_current_screen();
if ($screen->ID == 'acf') {
return true;
} else {
return false;
}
}
}
// Add in Rule Type
add_filter('acf/location/rule_types', 'acf_location_rules_types');
function acf_location_rules_types( $choices ) {
if (maybe_add_filters()) {
$choices['Other']['custom_field_types'] = 'ACF Custom Field Type';
return $choices;
} else {
return $choices;
}
}
I’ll add this once I move all of the corresponding ACF field groups to the PHP code and everything should be good to go!
