Set value from Database to ActiveForm

Hi guys i am new to yii2

so i know i am asking stupid question

but i could not figure out the solution

i have 2 tables


Organiser

Event



Organiser is logged in using the username and password

and he/she can create event

not there are couple of fields are almost same in Organiser and Event

so rather than asking them again to fill it up

i want to check the organiser_id on Event create action and send those value to

Create form

But i dont know how to do it

Do i need to pass 2 models to the create form

1 with organiser model and 2nd event model

or i can do it some other way

ok here is what i have done until now




public function actionCreate()

    {

        $model = new Event();


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


            $model->save();


            return $this->redirect(['view', 'id' => $model->id]);

        } else {

            $model2 = new User();


            $model2 = $this->findModel2(Yii::$app->user->id);


            return $this->render('create', [

                'model' => $model,

                'model2' => $model2

            ]);

        }

    }



Until now its good

But how can i check on the view form that the form is Create form or update form

It the form is create form than only i want to set the value from $model2

If its update form than it should take values from $model

How can i check that on form

here is code of my form





<div class="event-form">


    <span class="label label-danger">Fields marked with * are mandatory</span>

    <p></p>

    <?php $form = ActiveForm::begin([

        'options' => [

            'id' => 'create-event-form'

        ]

    ]); ?>


    <?= $form->field($model, 'interest_id')->dropDownList(

        ArrayHelper::map(Areaintrest::find()->all(),'id','area_intrest'),

        ['prompt'=> 'Select Event Category']

    ) ?>


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


    <?= $form->field($model, 'description')->widget(CKEditor::className(), [

        'options' => ['rows' => 6],

        'preset' => 'basic'

    ]) ?>


    <?= $form->field($model, 'location')->textInput(['class' => 'placepicker form-control']) ?>


    <di"form-group">

        <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-danger' : 'btn btn-primary']) ?>

    </div>


    <?php ActiveForm::end(); ?>


</div>
