如何通过用户id laravel 5.4从单行获取数据

Question

我是laravel的新手,我希望按用户ID获取用户的单个记录并在输入值中显示.请指导我

调节器

public function profile(){

    $userdata = User::all();

    return view('pages/edit-profile')->with('userdata',$userdata);
}

路线

Route::get('profile', 'PageController@profile_c');

表单视图

  <form class="form-horizontal" role="form" action="/edit_profile" method="post">
                    {{  csrf_field() }}
 <div class="form-group">
    <label class="col-lg-3 control-label">First name:</label>
      <div class="col-lg-8">
        <input class="form-control" name="firstName" id="firstName" type="text" value="Jane">
      </div>
 </div>
 <div class="form-group">
   <label class="col-lg-3 control-label">Last name:</label>
     <div class="col-lg-8">
       <input class="form-control" name="lastName" id="lastName" type="text" value="Bishop">
     </div>
 </div>
 <div class="form-group">
  <label class="col-lg-3 control-label">Display name:</label>
    <div class="col-lg-8">
       <input class="form-control" name="displayName" id="displayName" type="text" value="Jane Bishop">
    </div>
 </div>
  <div class="form-group">
    <label class="col-lg-3 control-label">Email:</label>
     <div class="col-lg-8">
      <input class="form-control" name="email" id="email" disabled type="email" value="janesemail@gmail.com">
     </div>
  </div>
 </form>

Answer 1

通过他们的id获取用户

$user = User::find(id);
return view('pages/edit-profile', compact('user));

如果您从用户那里了解其他与用户电子邮件类似的独特内容

$user = User::where('email', $email)->first();
return view('pages/edit-profile', compact('user));

在表单中,如果您使用刀片

<input name="email" value={{ $user->email }} />
