如何在OpenCart 2.3.0.2中设置全局变量? [英] How to setting global variables in OpenCart 2.3.0.2?

问题描述

当我想在模板(.tpl文件)中设置全局变量时，我只在opencart 2.2或更早版本中使用global.

When I want to set a global variable in template (.tpl files), I just use global in opencart 2.2 or older version.

例如:

<?php global $config; if($config->get('my_options')== 1) { ?>....<?php } ?>

但是，它在最新的OpenCart 2.3.0.2中不起作用

因为在控制器中预定义的global $config相当不方便(我们在许多模板文件中使用了config值). 希望有更多经验的人可以解决这个问题.

Because predefined global $config in controller rather inconvenient (we have use config value in many template file). Hopefully someone with more experience will have an answer to this problem.

推荐答案

在config.php或admin/config.php中，根据所需的位置，将它们定义为常量的最少代码.这将使这些常量在整个目录或管理上下文中立即可用.

The least code you will get defining them as constants in config.php or admin/config.php, depending on where you will need them. This will make these constants immediately available throughout the catalog or admin context.

另一种方法是通过在控制器中使用$ this-> config将键/值从设置表中获取到模型或控制器中.

Another way is by using $this->config in controllers to get key/values out of the setting table into your models or controllers.
