Hi, there!
I need to show if user name is not unique by ajax request (before user submit registration form).
How can i do that using validation rules and activeform?
array('username', 'unique', 'message' => UserModule::t("This user's name already exists."))
rule works, but only when user’s submited form
i’ve tried bind own onchange-event on input field.
When I send ajax-request to specify action, it also works
$item = new User;
$item->username = $login;
if (!$item->validate('username',$login))
{
if ($item->hasErrors())
{
...
i get ‘duplicate user’ error by validator!
But when i try to show it in error-field it seems conflict with activeform onchange-event function and not appears
tried options:
'on'=>'scenario'... 'enableClientValidation' => true...
not working 
has a solution?
This is actually built into Yii already. You don’t really need to create any custom code for it.
-
Create model + CRUD using gii.
-
Ensure model has unique validator.
array('username', 'unique', 'message' => UserModule::t("This user's name already exists."))
- Go into CRUD controller and uncomment ajax validation.
// Uncomment the following line if AJAX validation is needed
$this->performAjaxValidation($model);
- Go into view file _form.php and enable ajax validation.
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'register-form',
'enableAjaxValidation'=>true,
'enableClientValidation'=>true,
)); ?>

It’s clear…
Ajax validation is working
I need ajax validation of username (check unique rule) working before submit
Strange, but only this rule not responde on ‘change’ event.
Other rules are working!
array('username', 'unique', 'message' => UserModule::t("This user's name already exists.")),
array('username', 'length', 'max'=>20, 'min' => 3,'message' => UserModule::t("Incorrect username (length between 3 and 20 characters).")),
array('username', 'match', 'pattern' => '/^[A-Za-z0-9_]+$/u','message' => UserModule::t("Incorrect symbols (A-z0-9).")),
After form submitted unique-rule also working!
What could be wrong?

In controller, action create() check the code like this
$model=new User;
$this->performAjaxValidation($model);
also check the ajax validation function
protected function performAjaxValidation($model)
{
if(isset($_POST['ajax']) && $_POST['ajax']==='user-form')
{
echo CActiveForm::validate($model);
Yii::app()->end();
}
}
Post your complete rules.
Thanks.
Hi,
Actually one of the model form element was not defined properly .
When i fixed that then both ajax and client validation worked properly as specified in the above posts.

For others who may also have a problem with the validation:
I use 2 different models in 1 form. Here the ajax validation function looks as follows:
if(isset($_POST['ajax']) && $_POST['ajax']==='user-form') {
echo CActiveForm::validate(array($model1, $model2));
Yii::app()->end();
}
Maybe this helps
