php shopping cart deleting an item - php

Question

I am trying to build a shopping cart for a PHP project, however, I have ran into a problem. When I add items to the cart session, I have them displayed in a cart summary.
Item 1 Item 2 Item 3
Whenever I delete an item, the other items below it deletes.
For example, if I delete Item 2 then Item 3 deletes, as well.
If I delete
Item 1,
Items 2 and 3 deletes, too.
update-cart.php
<code>
if(isset($_GET["removep"]) && isset($_GET["return_url"]) && isset($_SESSION["products"]))
{
$prod_id = $_GET["removep"];
$return_url = base64_decode($_GET["return_url"]);
foreach($_SESSION["products"] as $cart_itm)
{
if($cart_itm["prod_id"]!=$prod_id)
{
$products[] = array('prod_name'=>$cart_itm["prod_name"],'prod_id'=>$cart_itm["prod_id"], 'prod_price'=>$cart_itm["prod_price"], 'prod_percent'=>$cart_itm["prod_percent"], 'prod_qty'=>$cart_itm["prod_qty"]);
}
else
{
$_SESSION["products"] = $products;
}
}
header('Location:'.$return_url);
}
</code>
widget_summary.php
<code>
if(isset($_SESSION['products']))
{
$total = 0;
echo '<ul>';
foreach ($_SESSION["products"] as $cart_itm)
{
$new_price = discount($cart_itm["prod_price"], $cart_itm["prod_percent"]);
echo '<table class="cart-items">';
echo '<tr>';
echo '<td>'.$cart_itm["prod_name"].'</td>';
echo '<td><span class="remove-item right">×</span></td>';
echo '</tr>';
echo '<tr>';
echo '<td id="qty">Qty: '.$cart_itm["prod_qty"].' × $'.$new_price.' = </td>';
$sub = $cart_itm["prod_qty"] * $new_price;
echo '<td class="right subtotal">$'.number_format($sub,2).'</td>';
echo '</tr>';
echo '</table>';
$subtotal = ($new_price*$cart_itm["prod_qty"]);
$total = number_format($total + $subtotal, 2);
}
echo '<table class="tbl-summary-footer">';
echo '<tr>';
echo '<td> Total </td>';
echo '<td><span class="price_now right"><strong>$'.$total.'</strong> </span></td>';
echo '</tr>';
echo '<tr>';
echo '<td><span class="empty-cart">Clear Cart</span></td>';
echo '<td><span class="right">Check-out!</span></td>';

Answer 1

Declare $products before the foreach loop.
You will need to set the session key 'products' after the loop.
