未定义的索引：RegisterController.php中的user_role

Question

我想将单选按钮值保存到用户数据库。但有一个 ERROR：

Undefined index: user_role in RegisterController.php

可我知道如何解决这个问题？

迁移：

Schema::table('users',function(Blueprint $table) 
    { 
     $table->integer('user_role'); 

    }); 

注册控制器：

protected function create(array $data) 
{ 

    return User::create([ 
     'name' => $data['name'], 
     'email' => $data['email'], 
     'password' => bcrypt($data['password']), 
     'stuID'=> $data['stuID'], 
     'user_role'=>$data['user_role'], 
    ]); 
} 

刀片文件：

<form class="form-horizontal" role="form" method="POST" action="{{ 
     route('register') }}"> 
       {{ csrf_field() }} 

<label for="user_role" class="col-md-4 control-label ">Role</label> 

     <div class="user_role" id="user_role" data-toggle="buttons"> 
      <label class="btn btn-default user_role"> 
       <input type="radio" name="user_role" id="lecturer" value="1"> 
        <span class="radio-dot"></span> 
         <span class="user_role-word">Lecturer</span> 
      </label> 

      <label class="btn btn-default user_role"> 
       <input type="radio" name="user_role" id="student"value="2"> 
        <span class="radio-dot"></span> 
        <span class="user_role-word">Student</span> 
       </label> 
     </div>

如果提交表单时，你会不会选择一个单选按钮，你数组中不会有$data['user_role']索引。您可以通过制作表单中所需的单选按钮来防止此错误，或者在使用前检查阵列中的user_role索引。

return User::create([ 
     'name' => $data['name'], 
     'email' => $data['email'], 
     'password' => bcrypt($data['password']), 
     'stuID'=> $data['stuID'], 
     'user_role'=> isset($data['user_role']) ? $data['user_role'] : null 
    ]);
