Session array not updating

amber.long83 · #1 19-Dec-2009, 00:36

Hello everyone,

i am trying to build a simple online shopping cart. Been strugling with 2 dimensional sessions array and when i finally got it working the session array is not updating.

I want to be able to browse through each product page and keep adding the productid,quantity to $_session[cart].

But each time i add to cart the previous product ids and quantities are deleted from the session. Am i doing it correctly.

Somebody please help.Thanks in advance.

Code:

PHP Code:


<?php
foreach($_POST as $var => $value)
{
if($value != '')
{
// add to session
$_SESSION['cart'][$var] = $value;
}
}
?>
<?
foreach($_SESSION['cart'] as $pid => $qty)
{
echo "Product id: $pid, Quantity:$qty ";
echo "<br>";
}
?>

Thanks in Advance

From page to page, there should be a call to session_start(), or else the information will be lost between page transitions.

Typically, that function is at the top of each page where session use is involved. See this PHP api reference for more info.
