Greetings. I do edit the user profile, saving does not work. I found out experimentally that reading form fields in the model properties ( $model->load(Yii::$app->request->post()) ) does not work. Please help find out why. So, I give the code:

(I don’t cite all use and namespace - they are there, leaving only the essence)

 UserController.php (контроллер)  public function actionProfile()  {    $model = new ProfileForm(); // создаем объект модели с формой ProfileForm    if ($model->load(Yii::$app->request->post())) { // вот тут условие проходит, но функция не срабатывает - $model не содержит полей из формы      if ($user = $model->update()) {        return $this->redirect('/user/profile');      }    }    return $this->render('profile', [      'model' => $model    ]);  }

ProfileForm.php (form model)

 class ProfileForm extends Model {  public $username;  public $email;  public $firstname;  public $middlename;  public $lastname;  public function update()  {    $user = \Yii::$app->user->identity;    $user->country = $this->username;    $user->country = $this->email;    $user->firstname = $this->firstname;    $user->middlename = $this->middlename;    $user->lastname = $this->lastname;    return $user->save() ? $user : null;  } }

profile.php (view profile forms)

 $user = \Yii::$app->user->identity; <?php $form = ActiveForm::begin(['id' => 'form-signup']); ?> <?= $form->field($model, 'username')->label('Имя пользователя')->textInput(['value' => $user->username, 'readonly' => true]) ?> <?= $form->field($model, 'email')->label('Ваш e-mail')->textInput(['value'=>$user->email, 'readonly' => true]) ?> <?= $form->field($model, 'firstname')->label('Имя')->textInput(['value'=>$user->firstname]) ?> <?= $form->field($model, 'middlename')->label('Отчество')->textInput(['value'=>$user->middlename]) ?> <?= $form->field($model, 'lastname')->label('Фамилия')->textInput(['value'=>$user->lastname]) ?> <?= Html::submitButton('Сохранить', ['class' => 'btn btn-primary', 'name' => 'signup-button']) ?> <?php ActiveForm::end(); ?>

The object \Yii:$app->user->identity is implemented in the Users model. There is nothing interesting here (just in case):

 <?php namespace frontend\models; use yii\db\ActiveRecord; use yii\web\IdentityInterface; class Users extends ActiveRecord implements IdentityInterface {  public static function tableName() {    return 'users';  }  public function setPassword($password) {    $this->password_hash = md5($password);  }  public function validatePassword($password) {    return $this->password_hash === md5($password);  }  public static function findIdentity($id) {    return self::findOne($id);  }  public function getId() {    return $this->id;  }  public static function findIdentityByAccessToken($token, $type = null) {  }  public function getAuthKey() {  }  public function validateAuthKey($authKey) {  } }

So, by experience, I found out that the problem is in the controller (at the very beginning):

 if ($model->load(Yii::$app->request->post())) {

condition is triggered. But as far as I understand, the $model = load($post_data) must read the elements of the $post_data and fill them in the $model array, provided that both elements have the same indices.

That is, it was:

 ['username' => 'тут старые данные из базы'], ['email' => 'тут старые данные из базы'], ['firstname' => 'тут старые данные из базы'], ['middlename' => 'тут старые данные из базы'], ['lastname' => 'тут старые данные из базы'], Yii::$app->request->post() [ ['username' => 'тут новые данные из формы'], ['email' => 'тут новые данные из формы'], ['firstname' => 'тут новые данные из формы'], ['middlename' => 'тут новые данные из формы'], ['lastname' => 'тут новые данные из формы'], ]

After if ($model->load(Yii::$app->request->post())) should be:

 $model [ ['username' => 'тут новые данные из формы'], ['email' => 'тут новые данные из формы'], ['firstname' => 'тут новые данные из формы'], ['middlename' => 'тут новые данные из формы'], ['lastname' => 'тут новые данные из формы'], ]

But the $model data is not updated. I have been looking for examples of using the load() function for a long time, and it seems to me that I understood correctly how it works. But why then does not save occur? When creating a new user, I did the same and everything worked, and when editing it does not work. Please help. Thank you in advance.

    Because all the fields of your model are not secure by default and the load() method does not work.

    In ProfileForm you need to add the rulse() method, at least with just an indication that you trust your attributes:

     public function rules() { return [ [['username', 'email', 'firstname', 'middlename', 'lastname'], 'safe'] ]; }

    You can use any other validator, which will also indicate that the attribute is safe (that is, it is validated by the validator).

    PS Check if ($model->load(Yii::$app->request->post())) will be equal to if(!empty($_POST)) or if(isset($_POST['ModelName'])) depending on the situation. This is what would be clear why the test is underway.
