PHP how to store the quantities alongside the products which the user has added to their cart.

[220061]

Hello I'm trying to create this shopping cart and I dont understand how to store the quantities alongside the products which the user has added to their cart. I know I need a session but thats all i know. I have tried to do:

$_SESSION['quantity'] = $_POST['quantity'];

or making an array and put these two in there

$_SESSION['qty'][] = $row['broodnaam'];
$_SESSION['qty'][] =  $_POST['quantity'];

but these things don't work either does anyone else have an idea?

<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errrors', '1');

include "config.php";
        ?>
        <div class="text-center" style="font-size: 100px;">&#128717;</div>
        <h2 class="text-center">Winkelmandje</h2><br>
        <section class="container content-section">
            <!-- <h2 class="section-header">CART</h2> -->
            <div class="cart-row">
                <span class="cart-item cart-header cart-column">ITEM</span>
                <span class="cart-item cart-header cart-column">PRICE</span>
                <span class="cart-item cart-header cart-column">QUANTITY</span>
                <span class="cart-item cart-header cart-column">berekening</span>
                <!-- <span class="cart-item cart-header cart-column">Verwijderen</span>   -->
            </div>
            <?php
            $broodjes = $_GET['broodjes_ID'];
         
            if (isset($_SESSION['basket'])){
                if( in_array( $broodjes ,$_SESSION['basket']) )

Hi,

it is hard to help others just by seeing their code and not without trying.

You can try to debug

$_SESSION

after value has been set to it using

var_dump($_SESSION);
