未定义的变量类别和未定义的变量i。发生错误。我无法显示控制器的数组值，所以请帮我解决这个错误 这是我的header.php控制器文件：

这是我的HTML代码：
<li><a href="<?php echo $category['manufacturer'][$i]['href']; ?>"><?php echo $category['manufacturer'][$i]['name']; ?></a></li>
答案 0 :(得分：1)
正如我在控制器中所理解的那样，您将$key作为字符串'0 - 9'或从$result['name']获取的单个大写字母。？
如果好，现在？
你从哪里得到$i？因为我还没有在你的控制器中看到它！并且你的html行在$ categories foreach循环中吗？
要在您的视图中访问$i，您必须在控制器中$data['i'] = something;
