php - Yii2 give array fields names and save to database -

can give each item saved array , database name.

for example have 3 form fields saved same array. can setup fields below or if below not correct best way it?

echo $form->field($model, 'arrayfields')->textinput([     'name'=>'field1inarray[]',     ]);  echo $form->field($model, 'arrayfields')->textinput([     'name'=>'field2inarray[]',     ]);  echo $form->field($model, 'arrayfields')->textinput([     'name'=>'field3inarray[]',     ]); 

also how go saving array database in controller/model?

i used below in view

<?= $form->field($model, 'example[arrayfield1]')->textinput(['maxlength' => 255])->label('array field 1') ?>  <?= $form->field($model, 'example[arrayfield2]')->textinput(['maxlength' => 255])->label('array field 2') ?> 

and within controller save database did following

    public function actioncreate() {     $model = new somemodel();      if ($model->load(yii::$app->request->post())) {         $array = $_post['somemodel']['example'];         $model->stockists = json_encode($array);          $model->save();         return $this->redirect(['view', 'id' => $model->id]);     } else {         return $this->render('create', [             'model' => $model,         ]);     } } 

open code improvements, need add validation check whether or not post value exists.

now need work way value populated in update form.
