Question

I have a shooping cart and I would like to save the $_SESSION[‘cart’] which contains the $product_id => $quantity of the products that the user have choosen.
For example:

[cart] => Array
    (
        [366] => 2000
        [215] => 456
    )

First I serialize the $_SESSION[‘cart’] before I INSERT IT in my data base.

<?php
if($_SESSION['cart']) 
{
    $pedido= serialize($_SESSION['cart']);
}
?>

$sql1="insert into pedido(orden) values ('$pedido')";

Now in a different page I want to view the $_SESSION[‘cart’]. So I use:

$sql2 = "SELECT orden FROM pedido where id_pedido = '$ID'";
$rs2 = mysql_query($sql2, $conexio) or die("Error al consultar: ".mysql_error()); 
$row2 = mysql_fetch_row($rs2);
$id_usuario=$row2[0];
$_SESSION['cartguardado']= unserialize($id_usuario);

I know that In this last step I am doing something wrong. Any body could help me and help me finding the mistake?

Answer 1

Try to output $row2

$sql2 = "SELECT orden FROM pedido where id_pedido = '$ID'";
$rs2 = mysql_query($sql2, $conexio) or die("Error al consultar: ".mysql_error()); 
$row2 = mysql_fetch_row($rs2);
print_r($row2);
$id_usuario=$row2[0];
$_SESSION['cartguardado']= unserialize($id_usuario);

if $row2[0] is empty so something wrong with your data
