在Yii2中将数据从一个表单传递到另一个表单

Question

I am currently having problems trying to send data from one form to another form using a button. I have a program where by the client is requesting a new part for their vehicle. The user then applies online and when the part is approved, the user then enter the information into the system. The problem i have is that i am trying to send the relevant data from one form to another that form. Please assist

 <p>
        <?php
        if($model->status=="Approved")
        {
        echo Html::a('Insert into Parts', ['/parts/create?'.$model->lp], ['class' => 'btn btn-primary']) ;
        }
        ?>

    </p>

When the user click the button they are redirected to the send form to insert the part (that is the second image) but i want when the user click the button the information that is related to it is then transferred to the other form. sorry for my english

Answer 1

In your part controller in create method you should handle to scenario

GET request: here you will load the vehicle using id submitted using the button then you will populated needed fields in the form.

POST request: here you will validate your model before saving it and then you will show the view model page if things went well.

public function actionCreate($id){
  $vehicle = Vehicle::findOne($id);
  $part = new Part();
  //now we have both Vehicle and new part object 
  //based on your desgin if you want to duplicate both your will do this 
  $pary->lincense_plate = $vehicle->lincense_plate;
  //do it for all then the fields will have values if you use ActiveForm

  //better desgin to avoid duplication and have a relation one to many between vehicle and part
  //send both models and show vehicle data as disable field or span 

  //here we handel post case
  if (Yii::$app->request->isPost) {
    $part->load(Yii::$app->request->post());
    if ($part->save())
      //render view page
      return $this->redirect(['view', 'id' => $part->id]);
  }
  return $this->render('create', [
            'vehicle' => $vehicle,
            'part' => $part,
        ]);
}
