Question

I can’t figure out the error above. Has anyone seen this before. I am using PHP with Smarty and incorporating PDO into my code.

PHP var_dump of code $data $smarty->assign("results", $data);

 object(PDOStatement)#22 (1) { 
  ["queryString"]=> string(236) "SELECT p.id,p.brag,p.brag_desc,p.brag_id,p.user_id, p.panel_id,p.domainurl,p.type,p.price FROM ruj_users_bg as p left join ruj_users as u on p.user_id=u.id WHERE u.status !=0 and 1 and p.status = 1 GROUP BY p.id DESC LIMIT 0 OFFSET 25" }

PHP Error from Smarty template:

Notice: Object of class PDOStatement could not be converted to int in /var/www/vhosts/somesite.com/httpdocs/templates_c/3d14690fd8419657273a6dce45bbca85dfc1e261.file.bragsdata.tpl.php on line 25

Line 25 from Smarty template:

$_smarty_tpl->tpl_vars[‘smarty’]->value[‘section’][‘res’][‘loop’] = is_array($_loop=$_smarty_tpl->getVariable(‘results’)->value) ? count($_loop) : max(0, (int)$_loop); unset($_loop);

Not sure where the problem is here. Your help is very appreciated.

update: Function call with fetchAll(PDO::FETCH_ASSOC);

 $data = fetchData($limit_start,$page_records);

 function fetchData$limit_start,$page_records){
            $db = Core::getInstance();
            $sql = "SELECT id FROM ruj_users_bg WHERE
                   (type = :type3 OR type = :type4) 
                   AND status =:uno 
                   ORDER BY id DESC LIMIT :lim OFFSET :page";

    $res = $db->dbh->prepare($sql);
            $res->bindValue(':type3',3, PDO::PARAM_INT);                
            $res->bindValue(':type4',4, PDO::PARAM_INT);
            $res->bindValue(':uno',1, PDO::PARAM_INT);
            $res->bindValue(':lim',(int)$limit_start, PDO::PARAM_INT);
            $res->bindValue(':page',(int)$page_records, PDO::PARAM_INT);
    $res->execute();
        $res->fetchAll(PDO::FETCH_ASSOC);       

    return $res;

}

That’s because PDOStatement is strictly not an array type. It implements Traversable though, so I’m surprised that Smarty doesn’t accept it as something that can be looped over.

To turn your database results into a standard array, you’d have to use ->fetchAll():

$smarty->assign('results', $data->fetchAll(PDO::FETCH_ASSOC));
