laravel形式模型綁定未定義$用戶

Question

我得到的錯誤

未定義的變量：用戶（查看： d：\ wamp64 \ WWW \項目\資源\意見\ ADMIN \用戶\ updateUser.blade.php ）

但我找不到爲什麼$ user是一個未定義的變量。 對於我使用laravel表單模型綁定的表單。

UserController.php

<?php namespace App\Http\Controllers; 
use App\Http\Requests\UserFormRequest; 
use App\Http\Controllers\Controller; 
use Illuminate\Support\Facades\Session;

public function index() 
{ 
    // show the list of all users 
    $users = \App\User::all(); 
      $User = new \App\User(); 
      $userRoleOptions = \App\Roles::pluck('role_name', 'id'); 
    return view('admin.user.indexUser', ['users' => $users, 'User' => $User, 'userRoleOptions' => $userRoleOptions]); 
} 
/**

    $user = \App\User::findorfail($id); 
      // delete the found user 
    $user->delete(); 
    $users = \App\User::all(); 
    return view('admin.user.indexUser')->with('users', $users); 
}

    $this->validate($request, [ 
      'name' => 'required|max:255',

    Session::flash ('flash_message', 'Account is succesvol aangemaakt!'); 
    $users = \App\User::all(); 
     $User = new \App\User(); 
     $userRoleOptions = \App\Roles::pluck('role_name', 'id'); 
    return view('admin.user.indexUser', ['users' => $users, 'User' => $User, 'userRoleOptions' => $userRoleOptions]);

    return view('admin.user.updateUser', array('user' => $user, 'User' => $User, 'userRoleOptions' => $userRoleOptions)); 
} 
public function update(UserFormRequest $request)

    $user = \App\User::findorfail($request->input('id')); 
     // validate user input 
    $this->validate ($request, [

    $user->name = $request ['name']; 
    $user->email = $request ['email']; 
    if (strlen ($request ['password']) > 6) { 
     $user->password = bcrypt ($request ['password']); 
    } elseif (strlen ($request ['password']) > 0) { 
     return redirect()->back(); 
    } 
    $user->role_id = $request['role_id']; 

    $user->save(); // no validation implemented 
    Session::flash ('flash_message', 'Account is succesvol gewijzigd!'); 
    $users = \App\User::all(); 
    $User = new \App\User(); 
    $userRoleOptions = \App\Roles::pluck('role_name', 'id'); 
    return view('admin.user.updateUser', ['users' => $users, 'User' => $User, 'userRoleOptions' => $userRoleOptions]); 
} 
    } 

模型用戶

<?php namespace App; 

    use Illuminate\Auth\Authenticatable; 
    use Illuminate\Database\Eloquent\Model; 
    use Illuminate\Auth\Passwords\CanResetPassword; 
    use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;

    class User extends Model implements AuthenticatableContract, CanResetPasswordContract { 

use Authenticatable, CanResetPassword; 

/**

* @var string 
*/ 
protected $table = 'users'; 

/** 
* The attributes that are mass assignable.

protected $fillable = ['name', 'email', 'password', 'role_id']; 

/** 
* The attributes excluded from the model's JSON form. 
* 
* @var array 
*/ 
protected $hidden = ['password', 'remember_token']; 

public function mail_entry(){ 
    return $this->hasOne('\App\Mail_entry'); 
} 


public function role() 
{ 
    return $this->hasMany('\App\Roles', 'id', 'role_id'); 
} 
    }

Answer 1

的不傳遞變量$用戶作爲重定向提供的視圖。

通常當您編輯用戶時，您想要將back()返回到編輯頁面並進行更改。

我會建議使用更簡單的語法傳遞變量視圖：

return view('path.to.view', compact('user', 'users', 'foo', 'bar'));

可以改進的另一點是在路線。請閱讀Laravel Implicit Binding。
