Mixing
Update quantity In PHP Session Based Shopping Cart
Hello and a happy new year to everyone!
I work with php sessions...I have a cart...I want to update the quantity via session...
Here is my update action within the main file
if(isset($_POST["update"]))
{
if ($_SESSION["item_id"] = $_GET["id"])
{
$_SESSION['quantity'] = $_POST['quantity'];
}
}
And here is the form within the foreach loop to display the checked product
$total = 0;
foreach ($_SESSION['cart'] as $item) {
?>
<tr>
<td><?php echo $item['name']; ?></td>
<td>
<form method="post" action="index2.php?action=update&id=<?php echo
$item["item_id"]; ?>">
<input type="text" name="quantity" value="1" class="form-control" />
<input type="submit" name="update" style="margin-top:5px;" class="btn btn-success" value="update" />
</form>
<?php echo $_SESSION['quantity']; //here I try to dislpay the new quantity that the user sets
echo $item["item_id"]; ?></td>
Problem
It changes the quantity in all the products within the basket and not in the specific one I want.
Please forgive me because I am a new bye.

Ummm - that looks like you only have one single quantity value in the session ... and item_id is looking pretty scalar as well...?

Yes the session takes value from previous add to basket form. All I want is to change the value that the session has!

Sessions are user based. You only have 1 quantity session variable so if you change it then anywhere that you use it will have that value for that user's browser session. You'd need a different variable for each quantity or perhaps and array with the values.

I added one more dimension to the $_SESSION array, using the item ID:
$_SESSION['item'][$_GET['id']]['quantity'] = $_POST['quantity'];
Then when updating the quantity in the form:
echo $_SESSION['item'][$item['item_id']]['quantity'];
