opencart - 如何在标题打开购物车中显示购物车中的计数项目？

Question

我需要在页眉中显示购物车中的商品数量。

我试图将header.php文件编辑为：

$products = $this->cart->getProducts();
$data['total'] = count($products);

然后在模板中显示这个header.tpl：

<?php echo $total?>

Answer 1

Your code should work, but you can also use command $this->cart->countProducts()
