Am creating complex forms. I have two Model Classes Courses and CourseStructure
public function actionCreate()
{
$model = new Course();
$request = Yii::$app->request;
if ($model->load(Yii::$app->request->post()) && Yii::$app->request->isAjax) {
//The course was created successfully, so we can use its data to make course structure
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
if ($model->load(Yii::$app->request->post())) {
$model->attributes = $_POST['Course'];
$model->course_start_date = date('Y-m-d', strtotime($_POST['Course']['course_start_date']));
$model->created_at = new \yii\db\Expression('NOW()');
$coursefile = UploadedFile::getInstance($model, 'coursefile');
if(!is_null($coursefile))
{
foreach ($this->coursefile as $file) {
$model->course_file_name = $coursefile->name;
$ext = end((explode(".", $coursefile->name)));
// generate a unique file name to prevent duplicate filenames
$model->course_file_path = Yii::$app->security->generateRandomString().".{$ext}";
Yii::$app->params['uploadPath'] = Yii::$app->basePath . '/../web/data/course_admin_files/course_files/';
$path = Yii::$app->params['uploadPath'] . $model->course_file_path;
$file->saveAs($path);
}//foreach
}
$model->save(false);
if($model->save(false))
//The course was created successfully, so we can use its data to make course structure
{
// check if topic format
if($model->course_format == Course::TYPE_TOPIC)
{
for( $i = 1; $i <= $model->course_format_no; $i++ )
{
$structure = new CourseStructure();
$structure->course_id = $model->course_id;
$structure->structure_name = $model->course_format . $i;
$structure->structure_id = $i;
// fill in other course structure data here
$structure->save();
}
}
}
else
return $this->render('create', ['model' => $model,]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
From CourseControllers, if course_format = TYPE_TOPIC, then based on the course_format_no selected,
some rows are added in course_structure table (CourseStructure) using
if($model->course_format == Course::TYPE_TOPIC)
{
for( $i = 1; $i <= $model->course_format_no; $i++ )
{
$structure = new CourseStructure();
$structure->course_id = $model->course_id;
$structure->structure_name = $model->course_format . $i;
$structure->structure_id = $i;
// fill in other course structure data here
$structure->save();
}
}

It works fine in CourseCreate Action in CourseControllers
Now how do I do it for the CourseUpdate Action, so that if that either reduce the number of rows or increase it in course_structure table based on the course_format_no added in the update.
This what I have, but how do I improve it to update CourseStructure
public function actionUpdate($id)
{
$model = $this->findModel($id);
$old_model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && Yii::$app->request->isAjax) {
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
if ($model->load(Yii::$app->request->post())) {
$model->attributes = $_POST['Course'];
$model->course_start_date = Yii::$app->dateformatter->getDateFormat($_POST['Course']['course_start_date']);
$model->updated_by = Yii::$app->getid->getId();
$model->updated_at = new \yii\db\Expression('NOW()');
if($model->save(false))
return $this->redirect(['view', 'id' => $model->course_id]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
I only write code for Courses, but dont know how to include course_structure into it.
