Php 在opencart中安装模块时创建表

我知道在安装插件时如何在wordpress中创建表。但在opencart中我不知道。请帮助了解如何在安装模块时创建新表。我已经粘贴了用于安装模块的test.php代码

您可以在控制器中添加install（）方法，该方法将在安装时运行。只需在那里执行SQL即可

[09/08/2013]您可以在这里看到，希望这也能帮助其他人解决这个问题

这可能有助于您在安装模块期间创建表

上面提到的两页都有一点错误： 它们在

查询的末尾缺少
引擎…
，因此请修复：

$this->db->query("CREATE TABLE IF NOT EXISTS `" . DB_PREFIX . "table_Name` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `date_added` datetime NOT NULL,
      `status` tinyint(1) NOT NULL,
      `fieldName` text(2) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=0;");

是的，我知道了。但我不知道怎么做。你能让我知道吗
