Getting error when pages are being requested

Question

I had someone build out a custom CMS for a small site and now I can't get a hold of the developer. I get this error when trying to view my site:

You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version
for the right syntax to use near 'order by sortorder' at line 1:

select path, title
from pages
where parent_id =
order by sortorder

After some help I was able to I think pin point where the problem is:

public function getChildLinks()
{
    $list = array();
    $WHERE_path = substr($_SERVER['REQUEST_URI'], 1);
    $WHERE_path = strlen($WHERE_path) ? '= "'.$WHERE_path.'"' : 'IS NULL';
    $parentPageRowset = Axl_Db::query('SELECT id, parent_id FROM '.$this->_name.' WHERE path '.$WHERE_path);
    $parent_id = $parentPageRowset[0]['parent_id'] ? $parentPageRowset[0]['parent_id'] : $parentPageRowset[0]['id'];
    $listRowset =  new Axl_Db_Rowset('SELECT path, title FROM '.$this->_name.' WHERE parent_id = '.$parent_id.' ORDER BY sortorder');
    while($listRowset->next())
    {
        $list['/'.$listRowset->path] = $listRowset->title;     
    }
    return $list;
}

This is the function causing the problem.

Answer 1

Well after getting great feed back from Adam I was able to really pin point what file I needed to fix and or look into a little deeper.

It turns out that I needed to quote out the parent_id variable

like so:

$listRowset =  new Axl_Db_Rowset('select path, title from '.$this->_name.' where parent_id = "'.$parent_id.'" order by sortorder');

Thanks Adam for your help
