E-shop

The cart accepts products from anywhere: CMS products or an external catalogue. The theme provides each product with productData(). Every time the cart is shown, prices and stock are synchronised and the customer is told if something changed.

// functions.php in the theme
function productData($productKey): array
{
    $p = PageDetail($productKey);              // here: a CMS product; it can also be an external catalogue
    return [
        'product_key' => $productKey,
        'product_sku' => $p['sku'] ?? $productKey,
        'title'       => $p['title'],
        'image'       => $p['thumb'] ?? '',
        'link'        => $p['url'],
        'price'       => (float)$p['price'],        // list price
        'sale_price'  => (float)$p['sale_price'],   // final price
        'vat'         => 24.0,
        'stock'       => (float)$p['stock'],
        'product_status' => 1,                      // 0 = unavailable
        'min_qty' => 1, 'max_qty' => 50, 'step_qty' => 1,
        'weight' => 0.35, 'width' => 12.0, 'height' => 10.0, 'length' => 9.0,   // kg / cm
        'shipping_time' => 1,                       // dispatch days
        'is_service'  => 0,                         // 1 = service, no shipping
    ];
}
