Store items in SESSION from array on link click

Question

I currently have a table populated from an array. The issue i'm having is storing the products on "Add to Cart"

    <?php
session_start();
$products = array(
array('SKU'=>'test1', 'name'=>'ProductTest1', 'Price'=>10.00),
array('SKU'=>'test2', 'name'=>'ProductTest2', 'Price'=>11.00),
array('SKU'=>'test3', 'name'=>'ProductTest3', 'Price'=>12.00)
);

if(isset($_GET['action' && $_get['action'] == "addToCart"))
{
$id = $_GET['product']);
if(isset($_SESSION['cart'][$id])){
$_SESSION['cart'][$id]['quantity']++;
}
else
{


?>

Below is also the table php which populates correctly.

<?php foreach ($products as $key => $product) {
echo '<tr>';
echo '<td>' . $product['SKU'] . '</td>';
echo '<td>' . $product['name'] . '</td>';
echo '<td>' . '&pound;'. number_format($product['Price'],2) . '</td>';
echo '<td><a href="?action=addToCart&product='. $key.'">Add To Cart </a></td>';
echo '</tr>';
}
?>

I can't figure out how to store the name and price of the items using the GET function, which should take the value from the URL.

Any help would be great!

Answer 1

Copy the element from $products into the session variable to get the name, SKU, and price.

if(isset($_SESSION['cart'][$id])){
    $_SESSION['cart'][$id]['quantity']++;
} else {
    $_SESSION['cart'][$id] = $products[$id];
    $_SESSION['cart'][$id]['quantity'] = 1;
}

Now other scripts can access $_SESSION['cart'][$id]['name'] and $_SESSION['cart'][$id]['Price'] .

Another option would be to put the $products definition in an include file, which is loaded by the other page to get this information.

Eventually you'll probably want to put your product information in a database, which could be accessed by both pages.
