Programmatic Location Rules

Hi there!

I would like to load ACF fields for custom post types based on a set of conditions and NOT use Custom Location Rules. A brief use case / rationale:

If CPT A exists AND Theme Option Y is 1, then show Field Group 1 on CPT A in wp-admin

1. I want to set rules programmatically because I don’t want users to be able to override/mess up location rules via the field group options.
2. I’ve been poking around and according to some threads, it seems like hooking into acf/get_field_group is going to be the way to go, however it isn’t documented.

Is there any way I can do a filter hook to override a field group’s location rules based on programmatic conditions?

Thanks in advance!

I just gave an basic example of this filter here https://support.advancedcustomfields.com/forums/topic/hide-elements-for-specific-user-roles/

When I want to set things in the group what I do is export one to php so that I can see an example and then try to copy the example.

Hey John!

Thanks for pointing me in the right direction, this is what’ I’m using and it seems to accomplish what I need.

add_filter('acf/get_field_group', 'my_change_field_group');
function my_change_field_group($group) {

	$get_current_screen = get_current_screen();
	$get_current_post_type = $get_current_screen->post_type;
	$my_option = get_field('my-option','option');

	if (
		$get_current_post_type == 'my-cpt' &&
		$my_option == 'stuff' &&
		$group['key'] == 'group_123456789'
	) {
		$group['location'] = array(
			array(
				array(
					'param' => 'post_type',
					'operator' => '==',
					'value' => 'my-cpt',
				),
			),
		);
	}
	return $group;
};
