Adding property to an object

[eluser]Marcelo Kanzaki[/eluser]
Sorry, i don't know if this is the right place to ask this. But i really could use some help.

I'm using CI with PHP5 and when i went testing on the server, some bugs happened.

I have this function in on of my models and i didn't know that php4 doesn't support adding properties to objects the way i did. Can someone tell me how to get around this problem?

Code:

function find_ ($page_id)
    {
        $this->db->where('page_parent_id', $page_id);
        $this->db->order_by('page_created', 'DESC');
        $query = $this->db->get('fala_pages');
        
        foreach ($query->result() as $row)
        {
            $row->subpages = count( $this->find_($row->page_id) );
        }
        
        return $query->result();
    }

Code:

function find_ ($page_id)
    {
        $this->db->where('page_parent_id', $page_id);
        $this->db->order_by('page_created', 'DESC');
        $query = $this->db->get('fala_pages');
        
        foreach ($query->result() as &$row)
        {
            $row->subpages = count( $this->find_($row->page_id) );
        }
        
        return $query->result();
    }

Notice the & before the $row in your foreach. This means the $row is passed by refference and not by value, meaning you can modify that variable and change the original value.

You need to not only bind the new property to the row but you have to bind it to the array too.

Code:

$rows = $query->result();

foreach ($rows as $key=>$row)
{
   $rows[$key]->subpages = count( $this->find_($row->page_id) );
}
// php5 only
$rows = $query->result();

foreach ($rows as &$row)
{
   $row->subpages = count( $this->find_($row->page_id) );
}
