我正在尝试使用提供两个 php 脚本的控制器脚本创建一个简单的购物车,但我似乎遇到了一些问题。下面是我的三个脚本的代码,后面是我当前收到的错误消息。
<?php
$items = array(
array('radio_id' => '1', 'manufacturer' => 'Grundig', 'model' => 'G3', 'price' => 129.99),
array('radio_id' => '2', 'manufacturer' => 'Eton', 'model' => 'E5', 'price' => 99.99),
array('radio_id' => '3', 'manufacturer' => 'Eton', 'model' => 'E1', 'price' => 399.99),
array('radio_id' => '4', 'manufacturer' => 'Morphy Richards', 'model' => 'DRM Radio', 'price' => 199.99),
array('radio_id' => '5', 'manufacturer' => 'Sony', 'model' => 'ICF-SW7600GR', 'price' => 149.99),
array('radio_id' => '6', 'manufacturer' => 'TechniSat', 'model' => 'MultyRadio', 'price' => 149.99));
session_start();
if (!isset($_SESSION['cart']))
{
$_SESSION['cart'] = array();
}
print_r($_SESSION);
?>
