Hi Darshan,
You were right. The code from Ravi used an API function that did not return hidden group if the user is context was not logged.

Here is the updated code. Please make sure to update the profile field id with your own.

/**
 * Retrieves all group ids of which the user is a member or has requested membership or is banned.
 *
 * @param int $user_id user id.
 * @param int $limit per page.
 * @param int $page page number.
 *
 * @return array
 */
function bd_get_user_group_ids( $user_id, $limit = false, $page = false ) {
	global $wpdb;

	$pag_sql = '';

	if ( $limit && $page ) {
		$pag_sql = $wpdb->prepare( " LIMIT %d, %d", intval( ( $page - 1 ) * $limit ), intval( $limit ) );
	}

	$bp = buddypress();

	$group_sql = $wpdb->prepare( "SELECT DISTINCT group_id FROM {$bp->groups->table_name_members} WHERE user_id = %d {$pag_sql}", $user_id );

	return $wpdb->get_col( $group_sql );
}

/**
 * Sync user's groups
 *
 * @param int   $user_id       User id.
 * @param array $new_group_ids New group ids.
 */
function buddydev_sync_user_groups( $user_id, $new_group_ids ) {

	if ( ! $user_id || ! $new_group_ids || ! function_exists( 'groups_leave_group' ) ) {
		return;
	}

	$existing_user_group_ids = bd_get_user_group_ids($user_id );

	$removable_group_ids = array_diff( $existing_user_group_ids, $new_group_ids );
	$new_join_group_ids  = array_diff( $new_group_ids, $existing_user_group_ids );

	foreach ( $removable_group_ids as $group_id ) {
		groups_leave_group( $group_id, $user_id );
	}

	foreach ( $new_join_group_ids as $group_id ) {
		groups_join_group( $group_id, $user_id );
	}
}

/**
 * Sync user's groups on field save.
 */
add_action( 'xprofile_data_after_save', function ( BP_XProfile_ProfileData $object ) {
	$field_id = $object->field_id;

	// Replace field id with yours field id.
	$group_field_id = 5;

	// If not our field id return.
	if ( $group_field_id != $field_id ) {
		return;
	}

	$new_group_ids = wp_parse_id_list( $object->value );

	if ( empty( $new_group_ids ) ) {
		// should we remove existing groups?
		// let us avoid that for now.
		return;
	}

	buddydev_sync_user_groups( $object->user_id, $new_group_ids );
} );

This code does not need the the Auto group join plugin. You can still use the plugin for other purpose.

Hi mdc,
Thank you for the question.

No, The plugin is not able to handle multiple conditions currently. The plugin does not load fields/options via ajax, It simply shows/hides them.

If you are referring to our Ajax Registration plugin, then yes, the current code is compatible.

Hi James,
Thank you for the question.

Yes, you can do that with Profile Visibility Manager.

Hi James,
The search functionality is not offered by Xprofile Custom Field Types plugin.

It is offered by the BuddyBoss platform and is same for the native fields/custom fields. If you are able to use the link for native fields(such as Web etc), you can apply the same for custom field types.

Hi James,
Thank you for confirming. I am glad it worked.
