yii dropDownList使用Javascript动态填充数据以发布空值

Question

How do I retrieve the value which is populating data dynamically with Javascript in yii framework? When I post the data it's inserting the database as null

in view

<ul class="birthday">
    <li><?php echo $form->dropDownList($model, 'otherdate',array());?></li>
    <li><?php echo $form->dropDownList($model, 'othermonth',array());?></li>
    <li><?php echo $form->dropDownList($model, 'otheryear',array());?></li>
<script type="text/javascript">
    date_populate("EmailForm_otherdate", "EmailForm_othermonth", "EmailForm_otheryear");
</script>
</ul>

in controller

$model = new EmailForm;
if (isset($_POST['EmailForm'])) {
$model->attributes = $_POST['EmailForm'];
echo $model->otherdate; //value null
}

Answer 1

Have you added 'otherdate', 'othermonth' and 'otheryear' to the rules of your model?

public function rules() 
{
    return array(
        array('otherdate, othermonth, otheryear', 'safe'),
    );
}
