我正在尝试在opencart的admin部分添加一个新页面，并设法创建所有必要的文件和权限以显示它，但它不会显示任何结果。我正在尝试创建一个页面，我可以添加/编辑/删除我的世界食谱。但是，不是在数据库中显示每个配方的结果，而是显示“没有结果！”请帮助我，我被卡住了。

在View页面上，我打印出$recipes，它只显示array()，所以我猜测问题出现在Controller内，$recipes将数据插入其中。但据我所知，看起来它的设置正确！我很困惑大声笑。
答案 0 :(得分：1)
您需要在管理面板中启用控制器以显示您的控制器
管理员菜单＆gt;设置＆GT;用户组＆gt; 启用您的控制器
之后，您可以按此模式打开新页面
[admin url] /index.php?route=catalog/recipe
