添加新页面到opencart管理员

Question

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。

数据库表：

CREATE TABLE IF NOT EXISTS `oc_recipes` (
  `recipe_id` int(255) NOT NULL AUTO_INCREMENT,

  `item4` int(255) NOT NULL,
  `item5` int(255) NOT NULL,
  `item6` int(255) NOT NULL,
  `item7` int(255) NOT NULL,
  `item8` int(255) NOT NULL,
  `item9` int(255) NOT NULL,
  `product_id` int(11) NOT NULL,
  `sort_order` int(255) NOT NULL,
  PRIMARY KEY (`recipe_id`),
  UNIQUE KEY `product_id` (`product_id`)

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。

Answer 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
