Below code should work. However you should not use mysql but PDO or mysqli because mysql is deprecated.
<?php
require_once "include/include.php";
global $db;
global $lng;
$smarty = new Smarty;
$smarty = common($smarty);
$ads = array();
$featured_ads = mysql_query("SELECT * FROM class_ads where active=1 and featured=1 limit 50");
while ($temp = mysql_fetch_assoc($featured_ads)) {
$record = array();
$record['ad_id'] = $temp['id'];
$record['ad_title'] = $temp['title'];
//check for image if featured ad have image (Need to fetch only single image)
$featured_ads_images = mysql_query("select * from class_ads_pictures where ad_id={$record['ad_id']} order by order_no");
$img = mysql_fetch_assoc($featured_ads_images);
$record['img_id'] = $img['id'];
$record['ad_img'] = $img['picture'];
$record['img_folder'] = $img['folder'];
$ads[] = $record;
}
$smarty->assign('ads', $ads);
$db->close();
if($db->error!='') { $db_error = $db->getError(); $smarty->assign('db_error',$db_error); }
$smarty->display('header_featured.html');
close();
?>
In Smarty you can simple use it:
{foreach item=item from=$ads}
{$item.ad_id}
{$item.ad_title}
{$item.img_id}
{$item.ad_img}
{$item.img_folder}
{/foreach}
