PHP delete item from Shopping cart - php

Question

I created a very simple shopping cart that just add item s to it and delete items from it and empty the cart too now I know I have a lot of issues in my code but I am trying to fix them as well
first see my code
if (isset($_SESSION['cart'])) {
foreach ($_SESSION['cart'] as $c) {
echo $c['name'] . '<br />';
echo $c['price'] . '<br />';
echo 'Remove item<br />';
}
}
if (isset($_POST['buy'])) {
//header("Location:?pid=18&pl=" . $pl);
if (isset($_POST['buy'])) {
$getData = $db->prepare('SELECT * FROM plans WHERE id=?');
$getData->bind_param('i', $pl);
if ($getData->execute()) {
$res = $getData->get_result();
if (($pn = $res->fetch_object()) !== null) {
$proCode = rand(1, 100);
$item['name'] = $pn->plan_name;
$item['price'] = $pn->price_dollar;
$item['code'] = $proCode;
$_SESSION['cart'][] = $item;
}
}
}
}
echo 'Empty Cart';
if (isset($_GET['rc']) && isset($_SESSION['cart'])) {
$rem = $_GET['rc'];
$ses = $_SESSION['cart'];
foreach ($_SESSION['cart'] as $cartItem) {
if ($cartItem["code"] == $rem) {
unset($ses[$rem]);
}
}
/*if (($key = array_search($rem, $ses)) !== false) {
unset($ses[$key]);
}*/
var_dump($ses);
}
if (isset($_GET['ac']) == 'empty' && isset($_SESSION['cart'])) {
unset($_SESSION['cart']);
}
for now the adding new products is working fine with me but the issue
comes when I am trying to remove one item from the caret it return back and noting seems to happened, and the item still there in the cart

Answer 1

you are unsetting $ses variable not $_SESSION...
Please have a look at the updated code, you dont even need to use a forloop, you can just unset the variable as I done below
if (isset($_GET['rc']) && isset($_SESSION['cart']))
{
$rem = $_GET['rc'];
if(isset($_SESSION['cart'][$rem]))
{
unset($_SESSION['cart'][$rem]);
}
}
let me know if this help you
EDIT
Please update your buy product function to below one.. you are using auto increament key for array.. it should be the primary key (here your product code)
if (isset($_POST['buy'])) {
//header("Location:?pid=18&pl=" . $pl);
if (isset($_POST['buy'])) {
$getData = $db->prepare('SELECT * FROM plans WHERE id=?');
$getData->bind_param('i', $pl);
if ($getData->execute()) {
$res = $getData->get_result();
if (($pn = $res->fetch_object()) !== null) {
$proCode = rand(1, 100);
$item['name'] = $pn->plan_name;
$item['price'] = $pn->price_dollar;
$item['code'] = $proCode;
$_SESSION['cart'][$proCode] = $item;
}
}
}
}

try to change your deleting cycle to this:
foreach ($_SESSION['cart'] as $key=>$cartItem) {
if ($cartItem["code"] == $rem) {
unset($_SESSION['cart'][$key]);
}
