php - model->save() Not Working In Yii2

Question

Previously, I was not using $model->save() function for inserting or updating any data. I was simply using createCommand() to execute query and it was working successfully. But, my team members asked me to avoid createCommand() and use $model->save();

Now, I started cleaning my code and problem is $model->save(); not working for me. I don't know where i did mistake.

UsersController.php (Controller)

<?php
namespace appmodulesuserscontrollers;
use Yii;
use yiiwebNotFoundHttpException;
use yiifiltersVerbFilter;
use yiiswiftmailerMailer;
use yiifiltersAccessControl;
use yiiwebResponse;
use yiiwidgetsActiveForm;
use appmodulesusersmodelsUsers;
use appcontrollersCommonController;

class UsersController extends CommonController 
{
    .
    .

    public function actionRegister() {
    $model = new Users();

        // For Ajax Email Exist Validation
   if(Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())){
     Yii::$app->response->format = Response::FORMAT_JSON;
     return ActiveForm::validate($model);
   } 

   else if ($model->load(Yii::$app->request->post())) {
      $post = Yii::$app->request->post('Users');
      $CheckExistingUser = $model->findOne(['email' => $post['email']]);

      // Ok. Email Doesn't Exist
      if(!$CheckExistingUser) {

        $auth_key = $model->getConfirmationLink();
        $password = md5($post['password']);
        $registration_ip = Yii::$app->getRequest()->getUserIP();
        $created_at = date('Y-m-d h:i:s');

        $model->auth_key = $auth_key;
        $model->password = $password;
        $model->registration_ip = $registration_ip;
        $model->created_at = $created_at;

        if($model->save()) {
          print_r("asd");
        }

      }

    } 
    }
    .
    .
}

Everything OK in this except $model->save(); Not printing 'asd' as i echoed it.

And, if i write

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

}

It's not entering to this if condition.

And, if i write

if($model->save(false)) {
    print_r("asd");
}

It insert NULL to all columns and print 'asd'

Any help is appreciable. Please Help me.

Answer 1

It could be a problem related with your validation rules.

Try, as a test, to save the model without any validation in this way:

$model->save(false);

If the model is saved you have conflict with your validation rules. Try selectively removing your validation rule(s) to find the validation conflict.

If you have redefined the value present in active record you don't assign the value to the var for db but for this new var and then are not save.

Try removing the duplicated var.. (only the vars non mapped to db should be declared here.)
