Update data to related tables yii2 - php

Question

I have table USR and ORGANIZATION :
USR table
|ID | ID_APP | NAMA_APP|
ORGANIZATION table
|ID | NAMA |
I tried to insert data to USR table (ID_APP and NAMA_APP) from ORGANIZATION by ID (relationship). This my code :
UsersController :
public function actionUpdate($id)
{
$model = $this->findModel($id);
if (Yii::$app->request->post()) {
try {
$state = true;
$data = Yii::$app->request->post();
$transaction = Yii::$app->db->beginTransaction();
$model->ID_APP = $data['USR']['ID_APP'];
$model->NAMA_APP = $data['USR']['NAMA_APP'];
if (!$model->save()) {
$ErrorMessage = $model->getErrorMessage($model->getErrors());
throw new Exception($ErrorMessage);
}
$transaction->commit();
$message = "Success update Application ";
} catch (Exception $e) {
$state = false;
$transaction->rollback();
$message = $e->getMessage();
}
if ($state) {
Yii::$app->session->setFlash('successApplication', $message);
return $this->redirect(['view', 'id' => $model->ID]);
} else {
Yii::$app->session->setFlash('errorApplication', $message);
return $this->render('view', ['id' => $model->ID]);
}
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
My View :
<?php $org = \app\models\ORGANIZATION::find()->all(); ?>
<?= $form->field($model, 'ID_APP')->dropDownList(
ArrayHelper::map($org,'ID', 'NAMA'))->label('ID APP') ?>
I'm still beginner on php and yii2 framework How to get NAMA_APP (USR table) from NAMA (ORGANIZATION)?

Answer 1

Based on you view assumuning that you post the ID_APP and need to retrive the NAMA_APP for a separated store in USR
// make accessible your ORGANIZAZTION model with use eg:
// use common\models\ORGANIZATION; or
use yourapp\models\ORGANIZATION;
public function actionUpdate($id)
{
$model = $this->findModel($id);
if (Yii::$app->request->post()) {
try {
$state = true;
$data = Yii::$app->request->post();
$transaction = Yii::$app->db->beginTransaction();
$model->ID_APP = $data['USR']['ID_APP'];
// then you can use eg: the find method
// related to ORGANIZAZTION active record
$modelOrg = ORGANIZATION::find()->where(['ID_APP']=> $data['USR']['ID_APP'])->one();
$model->NAMA_APP = $modelOrg->NAMA_APP
