Opencart 页面意外停止并显示消息 "Use of undefined constant VERSION - assumed 'VERSION' "？

Question

Warning: Use of undefined constant VERSION - assumed 'VERSION' (this will throw an Error in a future version of PHP) in /home/xxxxxxx/you-r.in/public_html/catalog/controller/extension/module/so_extra_slider.php on line 193

站点已停止工作并突然显示此消息警告。 php 和 Opencart 版本都没有更新。代码如下所示：

// Check Version
if(version_compare(VERSION, '2.1.0.2', '>')) {
    if ($this->customer->isLogged() || !$this->config->get('config_customer_price')) {
        $price = $this->currency->format($this->tax->calculate($product_info['price'], $product_info['tax_class_id'], $this->config->get('config_tax')), $this->session->data['currency']);
    } else {
        $price = false;
    }
}

Answer 1

查看通常定义版本的 index.php。例如

<?php
// Version
define('VERSION', '2.3.0.2.3');

您可以像这样添加版本定义

define('VERSION', 'your-version-number');
// Check Version
if(version_compare(VERSION, '2.1.0.2', '>')) {
