Laravel 5表单请求和用户注册

Question

问题是，您需要同时注册用户，并使用其数据表单输入另一个表，并分配ID。

我试过了

$data = Request::all();

    $user = new App\User();
    $user->username = $data['name'];
    $user->email = $data['email'];
    $user->password = bcrypt($data['password']);
    $user->save();

如何立即获得新的用户ID？

记录其他数据，如

$question = new App\Question();
$question->name_q = $data['name_q'];
$question->body_q = $data['body_q'];
$question->user_id = ?

Answer 1

应该为此定义关系，以便在不创建两个不同表的对象的情况下轻松插入数据。让我们先看看你的情况，然后我将告诉你如何做更好的方法。

$data = Request::all();

$user = new App\User();
$user->username = $data['name'];
$user->email = $data['email'];
$user->password = bcrypt($data['password']);
$user->save();

$question = new App\Question();
$question->name_q = $data['name_q'];
$question->body_q = $data['body_q'];
$question->user_id = $user->id;
$question->save();

我们就完了。但是在这种情况下，您必须创建两个不同表的对象，并编写到现在为止还好的所有内容，但是当您必须一次将数据插入到多个表中时会发生什么。让我们看看：

首先定义您已经拥有的关系，让我们看看我们在模型中应该拥有什么：

//User model should have a questions function
public function questions()
  {
      return $this->hasMany('App\Question');
  }

//Question model should have a user model
public function user()
 {
        return $this->belongsTo('App\User');
 }

现在我们要做的是

$user = new App\User();
$user->username = $data['name'];
$user->email = $data['email'];
$user->password = bcrypt($data['password']);
$user->save();


$user->questions()->create([
            'field' => $somevariable,
             'field' => $someothervariable
        ]);
//here questions is the function name in User model
