Recursive function

  • Hello.

    I was wondering if i could get some help. I want to create a function to count all the unread documents in a group.

    I already did that for members, but now i’m struggling with this one. This is my approach:

    function bp_docs_get_unread_count_group($user_id = false, $group_id) {
	if ( false === $user_id ) {
		$user_id = bp_loggedin_user_id();
	}

	$unread_post_count = 0;
	if (bp_group_hierarchy_has_subgroups()) {
		// recursively call bp_docs_get_unread_count_group for every child
	} else {
		// for every member in the group call bp_docs_get_unread_count and add all the counts
	}

	if( $unread_post_count == 0) {
		$unread_post_count = '';
	}

	return $unread_post_count;

}

    Can anyone help me?

    Hi laurahreniucu –

    You can use this method call in place of bp_group_hierarchy_has_subgroups() to get a list of the immediate children:

    BP_Groups_Hierarchy::has_children( $group_id )

    Thank you David Dean for the response.

    I’m actually struggling with the recursive function. I can’t seem to make it work.

    This is my code so far (the ‘else’ is just a dummy for now):

    function bp_docs_get_unread_count_group($user_id = false, $group_id) {
	if ( false === $user_id ) {
		$user_id = bp_loggedin_user_id();
	}

	$unread_post_count = 0;
	$children = BP_Groups_Hierarchy::has_children( $group_id );

	if($children.length > 0) {
		foreach($children as $child) {
			$unread_post_count = $unread_post_count + bp_docs_get_unread_count_group($user_id,$group_id);
		}
	} else {
		$unread_post_count = 1;
	}

	if( $unread_post_count == 0) {
		$unread_post_count = '';
	}

	return $unread_post_count;

}
