How to display data in smarty when using PDO with prepared statement and executing inside foreach?

Question

$dbh = new PDO($dsn, $user, $password, array( 
 PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true));

$selectNumberTitle = $dbh->prepare("SELECT AdvertNumber, AdvertTitle FROM `adverts` WHERE AdvertNumber = ? ");

foreach ($advertnumber as $i => $number) {
    $selectNumberTitle->execute(array($number));
    foreach ($selectNumberTitle as $row) {
        echo $row['AdvertNumber'] . ') ' . $row['AdvertTitle'] . "<br/>";
    }
}

Above code works nicely. I need the same output in smarty.

Answer 1

$selectNumberTitleMerge = array();    
foreach ($advertnumber as $i => $number) {
    $selectNumberTitle->execute(array($number));
    foreach ($selectNumberTitle as $row) {
        $selectNumberTitleMerge[] = $row;
        echo $row['AdvertNumber'] . ') ' . $row['AdvertTitle'] . "<br/>";
    }
}
$smarty->assign('selectNumberTitleMerge', $selectNumberTitleMerge);

and code inside my template:

{foreach $selectNumberTitleMerge as $r} 
    {$r.AdvertNumber})
    {$r.AdvertTitle}
    <br>
{foreachelse}
    .. no results .. 
{/foreach}
