Thread: Function won't return value

Here is our first post in programming;

I have a very simple problem that has left me stuck and I was hoping you might be able to spot the error. This method will echo the value but will not return. Can you help me spot the error. The method works perfectly fine but will not return the value.

PHP Code:

     public function get_link_id ($permalink){
        $addition = 'WHERE PERMALINKS LIKE "%'.$permalink.'%"';
        if ($data = $this->get_data ($this->permalinks_table, '0', '1', $addition)){
            $link_id = $data[0]['LINK_UNIQUEID'];
            return $link_id;
        } else {
            return false;
        }
    } 


External code:

PHP Code:

$cached_uniqueid = $permalinks_obj->get_link_id ($post_perma);
echo $cached_uniqueid; 


Thanks...
