Why is table data not updating in Yii2?

Question

Yii

there is a form

<?php
use yii\helpers\Html;
use yii\bootstrap\ActiveForm;
$baseUrl = Yii::$app->request->baseUrl; 
?>
<div>
<? 
$username = $user -> username;
$mail = $user -> email;
$phone = $user -> phone;
$ava = $user -> ava;
$status = $user -> status;
$pass = $user -> password;
$id = $user -> id;
?>
<?php $form = ActiveForm::begin([ 'method' => 'POST', 'options' => ['enctype' => 'multipart/form-data']]) ?>
          <?= $form->field($EditUserAdmin, 'username')->textInput(['value' => $username]) ?>
          <?= $form->field($EditUserAdmin, 'email')->textInput(['value' => $mail]) ?>
          <?= $form->field($EditUserAdmin, 'phone')->textInput(['value' => $phone]) ?>
          <?= $form->field($EditUserAdmin, 'password') ?>
          <?= $form->field($EditUserAdmin, 'status') ?>
          <?= $form->field($EditUserAdmin, 'id')->textInput(['value' => $id]) ?>
          <?= $form->field($EditUserAdmin, 'ava')->fileinput() ?>
          <img src='<?='../../web/'.$ava?>'> <br>
          <?= Html::submitButton('Сохранить', ['class' => 'btn btn-success']) ?>
          <?php ActiveForm::end() ?>

</div>

Controller

public function actionUsers()
    {

                if(Yii::$app->request->get()){
                  $EditUserAdmin = new EditUserAdmin();
                  $user = $_GET['user'];
                  $user_result = User::find()->where(['username' => $user]) -> one();					
                  return $this->render('Edituseradmin',[
                  'EditUserAdmin' => $EditUserAdmin,
                  'user' => $user_result ]);
                }
 								if(Yii::$app->request->post()){	    
                  $id = $_POST['EditUserAdmin']['id'];			
                  $user = User::find()->where(['id' => $id]) -> one();
                  
                      $user->username=$_POST['EditUserAdmin']['username'];
                    $user->email=$_POST['EditUserAdmin']['email'];
                    $user->phone=$_POST['EditUserAdmin']['phone'];
                    $user->password=md5($_POST['EditUserAdmin']['password']);
                    $user->ava=$_POST['EditUserAdmin']['ava'];
                    $user->status=$_POST['EditUserAdmin']['status'];
                    $user->update();
                                    
                    return Yii::$app->response->redirect(Url::to('index'));
                } 
    $users = user::find()->all();	
    return $this->render('users',[
            'users' => $users,
        ]);  
    }

the data is passed to the POST array, but as I understand it, the if(Yii::$app->request->post()) condition in the controller does not work, I can’t understand why. Please tell me what I missed, there are no errors in the Yui debugger and there are no errors on the form, the data is simply sent and that's it, but they should be sent, go to the condition and work out the code after the condition.

Answer 1

1) Wildness .... Why do you directly access $ _POST when there is a load method
2) Instead Yii::$app->request->post()
, use
Yii::$app->request->isPost

Answer 2

1 Use instead of such constructions $_POST['EditUserAdmin']['username']on such

Yii::$app->request->post('EditUserAdmin')['username']

Well, if you use Yii2
Usually they use it differently Yii::$app->response->redirect(Url::to('index')
And like this this->redirect(['controller/index'])
The second point is usually not update() but save(), at least that's how I use it in my projects.
Include first errors something like this

if($user->save()){
return $user->getErrrors();
}

If it doesn't save it will throw an error.
If the post does not reach, then use approximately var_dump () And check whatever you want there to understand if the post is going through for you or not. Let's sayvar_dump(Yii::$app->response->post());

Answer 3

It is necessary to check the result of the call
which, unlike save() returns FALSE or the number of records changed, and save() only TRUE/FALSE.
Data may be rejected during validation.
