如何将购物车中的商品摘要从$ _SESSION显示到另一个页面

Question

I need my cart page to show a summary "line item" like view of all vending machines purchased on my vend page with $_SESSION['cart']

Here is my code which allows me to add multiple items to the cart: (Vend Page)

 session_start();

 //Check if $_SESSION['cart] exists
 if (!isset($_SESSION['cart'])) {

 //initiate cart as empty array      
    $_SESSION['cart'] = [];
 }

 if (isset($_POST['add'])) {

 //add product id to session cart
 $_SESSION['cart'][$_POST['add']] =1;
 }

 else if (isset($_POST['remove'])) {

    //remove product id from session cart
    unset($_SESSION['cart'][$_POST['remove']]);
}

I just need a way to display the items I "Add to Cart" on the Vend Page" to display in a list onto another page "Cart page". Ive made an image to show how it should be displayed: HERE

Answer 1

in your cart page add this -

session_start();
if (isset($_SESSION['cart'])) {
foreach ($_SESSION['cart'] as $name => $price){
    echo $name . " - " . $price;
 }
}else{
// optional(if cart is empty it will redirect to another page)
  header("location:products.php");
}
