I tried to create user controller using crud, it’s created but when I try to access my view I get an error message
Unable to find ‘frontend\controllers\UserController’ in file: I:\zzerver\Uwamp -port 84\uw-cms-p8585\www\yii26a/frontend/controllers/UserController.php. Namespace missing?
and the file I have it on frontend\controllers\UserController
can you paste the UserController.php’s code here

Namespace missing?
but it’s generated by CRUD, using gii; In crud I can’t generate using frontend I have to use app
if I use frontend I get this error message : Class ‘frontend\models\User’ does not exist or has syntax error.
But if I use app it generated
What’s “frontend”? Where do you want to use that word? Your app seems to run without any problem if you don’t insist using that word.
Where and when do you get this error?
when I try to generate a crud for user if I use : frontend\models\User
I get an error so I have to use app, and when I generate crud for user using app\models\User,
it’s generated but if I try to access user page I get the error
"Unknown Class – yii\base\UnknownClassException

I did some pictures

And what configurations do you have for frontend and backend in your web server?
BTW, didn’t you run “Gii” in the frontend and tried the CRUDs in the backend?
And is "app\models\User" different from "common\models\User"?
your namespaces are wrong gii does allow you to specify the namespace, what you need to change is your namespace here is your code modified
<?php
namespace frontend\controllers;
use Yii;
use app\models\User;
use app\models\UserSearch;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
/**
* UserController implements the CRUD actions for User model.
*/
class UserController extends Controller
{
//...
I run CRUd on frontend not on the backend, After I changed the namespace frontend\controllers; on my controller it’s working
but why CRUD don’t accept frontend or backend when I try to generate Controllers so I have to change the namespace on every Controller
Your screenshot shows the model generator.
As @alrazi says, you should be able to specify the controller namespace with the 3rd field of the CRUD generator.
And if "app\models\User" and "common\models\User" share the same table, you should not create "app\models\User". You could specify "common\models\User" in the CRUD generator.
THANK YOUUUUUUUUUUUUU
