在命令 Prestashop 中使用 getOrderTotal

Question

我正在尝试在 Prestashop 1.7 模块中创建一个命令来创建订单客户端购物车。 当我尝试使用

$cart->getOrderTotal

时，我总是收到致命错误。

 protected function execute(InputInterface $input, OutputInterface $output){
    try{
        $cart = new Cart(2433);
        $total = (float)$cart->getOrderTotal(true, Cart::BOTH);
        $output->writeln('total '. $total);
    }catch (Exception $e){
        $output->writeln('error'. $e->getMessage());
        die();
    }
}

错误详细信息是：

您遇到的问题似乎是由于 PrestaShop 核心未在您的脚本中正确初始化，这可能导致您在 getPriceStatic() 方法中提到的错误。

要解决此问题，您需要确保 PrestaShop 的环境设置正确。

确保包含 init.php ，类似

require_once('/path/to/prestashop/config/config.inc.php');

还要确保 Context 和 Employee 已初始化

$context = Context::getContext();
$context->employee = new Employee((int)Configuration::get('PS_EMPLOYEE_ID'));

如果您不确定员工 ID，您可以在默认 PrestaShop 设置中使用 1 作为超级管理员帐户。
