The above line is showing output from HTML code.

Controller code:

 public function actionGetQuotes()
 {
    $model = new GetQuotesForm();

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

          $model= array_key_exists('type_of_service_requires', $_POST)? $_POST['type_of_service_requires']:"";

          $model= array_key_exists('residential_commercial', $_POST)? $_POST['residential_commercial']:"";

          $model= array_key_exists('work_start_when', $_POST)? $_POST['work_start_when']:"";

          if ($model->save(false))
          {
               Yii::$app->getSession()->setFlash('success', 'New Info Was Saved.');
          }
    }
    return $this->render('get-quotes',['model' => $model,]);
}

It's showing: PHP Fatal Error – yii\base\ErrorException

Call to a member function save() on a non-object

Can anyone please help about this issue?

The problem is happening here for bellow lines-

      $model= array_key_exists('type_of_service_requires', $_POST)? $_POST['type_of_service_requires']:"";

      $model= array_key_exists('residential_commercial', $_POST)? $_POST['residential_commercial']:"";

      $model= array_key_exists('work_start_when', $_POST)? $_POST['work_start_when']:"";

Comment all 3 lines and try to submit the form again. It should work without error.

If you want to save submitted values with all above 3 lines then modify them in bellow format-

      $model->type_of_service_requires = $_POST['type_of_service_requires'];

      $model->residential_commercial = $_POST['residential_commercial'];

      $model->work_start_when = $_POST['work_start_when'];

Now model->save(false) will work after form submission. But if the form submission contains any empty value for any of three attributes then it will display error.

To solve this you can use following way for all three attributes-

 if(isset( $_POST['type_of_service_requires'] ))
    $model->type_of_service_requires = $_POST['type_of_service_requires'];

 if(isset( $_POST['residential_commercial'] ))
    $model->residential_commercial = $_POST['residential_commercial'];

 if(isset( $_POST['work_start_when'] ))
    $model->work_start_when = $_POST['work_start_when'];

Please add comments if the solution does not work. Add your error details in comments.
