问题描述

我正在尝试从此处在catalog/view/theme/default/template/checkout/confirm.tpl中实现以下代码

I am trying to implement below code from here in catalogue/view/theme/default/template/checkout/confirm.tpl

<?php if ($this->cart->getSubtotal() >= 1000) { ?>
<div id="payment"><?php echo $payment; ?></div>
<?php } else { ?>
<div class="warning">Minimum 10 Euro to checkout</div>
<?php }  ?>

但是我遇到错误

Notice: Undefined property: Loader::$cart in C:\xampp\htdocs\optest\catalog\view\theme\default\template\checkout\confirm.tpl on line 51
Fatal error: Call to a member function getSubtotal() on null in C:\xampp\htdocs\optest\catalog\view\theme\default\template\checkout\confirm.tpl on line 51

推荐答案

方法不一样，但您可以这样做:

Not the same way but you can do it like this:

将此行添加到checkout.php控制器文件中.

Add this line in your checkout.php controller file.

if ($this->cart->getSubtotal() < 1000) {
    $this->session->data['error'] = 'Your warning message';
    $this->response->redirect($this->url->link('checkout/cart'));
}

之后

if ((!$this->cart->hasProducts() && empty($this->session->data['vouchers'])) || (!$this->cart->hasStock() && !$this->config->get('config_stock_checkout'))) {
    $this->response->redirect($this->url->link('checkout/cart'));
}

就这样.
