在yii框架上进行一次验证来收集多个输入

Question

I'm using Yii framework and I have form with 3 inputs for phone number. I split it for this format (XXX-XXX-XXXX) every split by minus is input.
I want to validate it after user change/pass all 3 fields and give one error message if it is not valid. I want to save it with the same order and split it back to the same format.

This is example of my code.

    <?php echo $form->labelEx($model,'phone'); ?>

<?php echo $form->textField($model,'phone[0]'); ?>
<?php echo $form->textField($model,'phone[1]'); ?>
<?php echo $form->textField($model,'phone[2]'); ?>

How can I do that?

Answer 1

You can validate inputs at the controller and add error if needed:

// ...
$validator = new CRegularExpressionValidator;
$validator->pattern = '/^[0-9]{3}\-[0-9]{3}\-[0-9]{3}/';
if ( !$validator->validate( $model->phone[0] ) ) // Do this for all of your phone fields!
{
    // add error if not added yet: $model->addError( ... );
}
if ( $model->validate( null, false ) ) // notice the 2nd argument!
{
    // ...
}

Or you can define your own validator at the model class with pretty the same code (this is the better option I believe).
