It must be an array of values?
{$smarty.session.minhalista.0}
will show the first one. Or you can loop with foreach. |

what might be happening? I really need it.
see
in php
| Quote: | if ($_SESSION && $_SESSION['minhalista'] != null){
foreach($_SESSION['minhalista'] as $key => $value)
{
$id = $_SESSION['minhalista'][$key];
$sel = mysql_query("SELECT * FROM classificados WHERE business_id = '".$id."'");
while($row = mysql_fetch_array($sel)){
echo "id: ".$row['business_id']." | "."nome: ".$row['business_name']." <a href='#' class='del' rel='".$id."' nm='".$nome."'>DEL FAVORITOS</a><br /> ";
}
}
} |

You are selecting data from the database inside the loop. You don't want to do that in Smarty, do that in PHP.
In php in the while loop, instead of echoing push the contents to an array, then assign the array to smarty and loop over the array in the template.
Something like:
PHP:
| Code: | while($row = mysql_fetch_array($sel)){
$rows[] = $row;
}
$smarty->assign('rows',$rows); |
Smarty:
| Code: | {foreach $rows as $row}
{$row.id} | {$row.business_name} (etc)
{/foreach} |
