Category: Laravel Controller

Controllerでは、viewの指定なしにredirect()->back();と書ける。

一覧や編集ページから削除ボタンを押すと、$idを渡したcontroller destroyメソッドでdelete()で削除する。画像の場合は、unlink。
削除完了メッセージは、Session::flashでsetして、遷移後のページで、@if(Session::has())で、メッセージを表示する方法がある。

edit.blade.php

{!! Form::open(['method'=>'DELETE', 'action'=>['AdminUsersController@destroy', $user->id]]) !!}
        {{ csrf_field()}}
        
        <div class="form-group">
            {!! Form::submit('Delete User', ['class'=>'btn btn-danger']) !!}
        </div>
    {!! Form::close() !!}

AdminUsersController.php

public function destroy($id)
    {
        //
        User::findOrFail($id)->delete();
        return redirect('/admin/users');
    }

### flushの利用

use Illuminate\Support\Facades\Session;
public function destroy($id)
    {
        //
        User::findOrFail($id)->delete();

        Session::flash('deleted_user', 'The user has benn deleted');
        return redirect('/admin/users');
    }

index.blade.php

@if(Session::has('deleted_user'))
		<p class="bg-danger">{{session('deleted_user')}}</p>
	@endif

deleteする際には、belongsToでコネクトしている画像も削除する

public function destroy($id)
    {
        //
        $user = User::findOrFail($id);

        unlink(public_path() ."/". $user->photo->file);
        $user->delete();

        Session::flash('deleted_user', 'The user has benn deleted');
        return redirect('/admin/users');
    }

User.php

public function isAdmin(){
        if($this->role->name == "administrator" && $this->is_active == 1){
            return true;
        }
        return false;
    }

### ログイン後のページ設定
app/Http/Auth/AuthController.php

protected $redirectTo = '/admin';

ユーザ削除の仕様は、要件定義によって変わってくると思います。その場合は、controllerで制御する。

$ php artisan make:controller –resource PostsController

なるほど、method名がdeleteではなくdestroyってのは若干違和感を感じるが、こんなもんかしらね。
