如果用户类型为admin，则会转到admin页面；如果用户类型为normal，则会转到user页面及其所有数据。当用户类型不是admin时，您不发送任何用户数据。之所以生成此通知，是因为当用户不是管理员时，$records在usuario页面不可用 在具有相应数据的控制器中为admin和usuario方法创建admin方法

您的登录控制器： 添加这些方法

 // for admin data 
 public function admin (){

  $data['records']=$this->m_login->getDetails();
  $this->load->view('admin_view_page',$data);
}
// for user data 
public function usuario(){

    $data['records']=$this->m_login->getDetails();
    $this->load->view('usuario',$data);
}
修改

您在视图中有变量
$records
，但在控制器上没有

改变

$data['record'] = $this->m_login->getDetails();
到

另一种方法是在控制器上

查看usuario.php

<?php if ($records) {?>
<?php foreach($records as $record) {?>
<tr>
<td><?php echo $record['id'];?></td>
<td><?php echo $record['User'];?></td>
<td><?php echo $record['name'];?></td>
<td><?php echo $record['grade'];?></td>
<td><?php echo $record['date'];?></td>
</tr>
<?php } ?>
<?php } else { ?>
<tr> 
<td>No Results Found</td>
</tr>
<?php } ?>

仅举一个使用php哈希的示例 提示不要将计划密码存储在dbvarchar的数据库哈希密码列中 255

问问自己，
$records
在传递到和查看之前，如何以及在何处分配值？我是否已尽我所能确保分配的值有效？伙计，也许我有点头晕，但我不明白，问题出在哪里：/@DFriend可以帮我解决吗？：S:（，出现了什么dude？抱歉，还有其他事情要做。请确保您从模型中获得了良好的数据。换句话说，
$st[0]
是您所需要的吗？但是您没有添加admin/usuario函数dude:S。那怎么办？dude，我应该在哪里输出这个？：>另一种方法是在控制器上$results=$this->m_login->getDetails（）；$data['records']=array（）；if（$results）{foreach（$results as$result）{$data['records'][]=array（'id'=>$result['id']，'User'=>$result['User']，'name'=>$result['name']，'grade'=>$result['grade']，'date'=>$result['date']））}$this->load->view（'usuario'，$data）；在你的主页功能中，我重新编辑了它。还有登录示例我发誓，你帮了我很多。你实现了很多，非常感谢。但是我不明白，我的程序工作不正常，我尝试过，但不知道如何修改查询：/看一看：
