Getting data for 2 different models - Yii2

Question

I have a form that inside looks like that:

<?= $form->field($model, 'comment')->textarea(['rows' => 6]) ?>

<?= $form->field($presentation, 'attendance')->textInput(['maxlength' => true]) ?>

<?= $form->field($presentation, 'couples')->textInput(['maxlength' => true]) ?>

<?= $form->field($model, 'hire_price')->textInput(['maxlength' => true]) ?>

Then I collect received data with controller, like that:

$model = new PresentationPlaceHistory();
$presentation = new Presentations();

if ($model->load(Yii::$app->request->post()) && $model->save() && $presentation->load(Yii::$app->request->post())) {
    $pres = $presentation->findOne($model->presentation_id);
    $pres->attendance = $presentation->load(Yii::$app->request->post('attendance'));
    $pres->couples = $presentation->load(Yii::$app->request->post('couples'));
    $pres->save();
    return $this->redirect(['view', 'id' => $model->id]);
}
else {
    return $this->render('create', [
        'model' => $model,
        'presentation' => $presentation,
    ]);
}

But in the effect, it saves all, beside 'attendance' and 'couples', which are set to 0 (before this form they were null).

It doesn't matter what number I put, I get zero. It doesn't even have to be number, because validation doesn't work at all.

Answer 1

Change following two lines:

$pres->attendance = $presentation->load(Yii::$app->request->post('attendance'));
$pres->couples = $presentation->load(Yii::$app->request->post('couples'));

// to this
$pres->attendance = $presentation->attendance;
$pres->couples = $presentation->couples;

You have already loaded $presentation values here $presentation->load(Yii::$app->request->post()) and should be available to access directly.

Kinda messy code u got here. First of all, I suggest you not to use load() method, but its my personal preference. Read more about load . This method returns boolean , that is why you are getting 0 in model properties. In general, your code should look more like:

$model->load(Yii::$app->request->post());
if ($model->save()) {
    $pres = $presentation->findOne($model->presentation_id);

    $pres->attendance = $presentation->attendance;
    //etc ...
    $pres->save()
}

I dont know what is the point of your code, but this looks kinda pointless. Try to work with attributes , it is an array of all model properties. Or assign manually wanted properties of the model.

problem with your controller code, change following two lines

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

        $post_data=  Yii::$app->request->post();

        $pres = $presentation->findOne($model->presentation_id);

        /* change these two lines */
        $pres->attendance = $post_data['Presentations']['attendance'];
        $pres->couples =$post_data['Presentations']['couples'];
        /* change these two lines */

        $pres->save();
        return $this->redirect(['view', 'id' => $model->id]);
  } 
  else 
  {
        return $this->render('create', [
            'model' => $model,
            'presentation' => $presentation,
        ]);
  }
