Yii2 dropdown list value not persisted to database
I created a model called AssignForm:
<?php
namespace app\models;
use yii\db\ActiveRecord;
class AssignForm extends ActiveRecord
{
public $username;
public $organ_name;
public $role;
}
Then I added a function called actionAssign in SiteController:
public function actionAssign(){
$model = new AssignForm();
if($model->load(Yii::$app->request->post()) && $model->validate()){
Yii::$app->db->createCommand()
->update('users', ['post' => $model->post], "username = '$model->username' ")
->execute();
}
return $this->render('assign',['model' => $model]);
}
I also have a view file called assign.php:
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
?>
<?php $form = ActiveForm::begin(); ?>
<?php
echo $form->field($model, 'username')->dropDownList(\yii\helpers\ArrayHelper::map(\app\models\Users::find()->all(),'id','username'),
[
'prompt' => 'Select User!!'
]);
echo $form->field($model, 'role')->dropDownList(['0' => 'employee', '1' => 'responsible'],['prompt'=>'Select Option']);
?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
This displays the correct information, but does not save to the database. But when I use the following code in actionAssign it works fine:
Yii::$app->db->createCommand()
->update('users', ['post' => 'ssss'], "username = 'soghra' ")
->execute();
But I want to write using database information. How to add to database dynamically?
