Answer 1

I am assuming your table name is areas, and Areas is Model for that table.
Bellow i am repeating(not exactly) view code from your question and i am attaching ajax call on your pincode field and class property on your other text fields.
<?php echo $form->labelEx($model,'pin'); ?>
<?php echo $form->textField($model,'pin',array(
'size'=>6,
'maxlength'=>6,
'style'=>'height:34px;',
//Ajax call to get the pin related values, onBlur.
'ajax' => array
(
'type' => 'POST',
'dataType'=>'JSON',
'url' => CController::createUrl('site/getValuesByPincode'),
'success'=>'js:function(output){$(".setVillage").val(output.village); $(".setStreet").val(output.street);}'
)
)); ?>
<?php echo $form->error($model,'pin'); ?>
<br/><br/>
<?php echo $form->labelEx($model,'street'); ?>
<?php
//adding a class
echo form->textField($model,'street',array('size'=>25,'maxlength'=>25,'style'=>'height:34px;','class'=>'getStreet'));
?>
<?php echo $form->error($model,'street'); ?>
<br/><br/>
<?php echo $form->labelEx($model,'village'); ?>
<?php
//Ading a class
echo $form->textField($model,'village',array('size'=>25,'maxlength'=>25,'style'=>'height:34px;','class'=>'getVillage'));
?>
<?php echo $form->error($model,'village'); ?>
And i am creating an action getValuesByPincode in my controller(ex: site controller) to serve my ajax call.
public function actionGetValuesByPincode()
{
$pincode = $_POST['Areas']['pin'];
$data = Areas::model()->find('pin=:pin', array(':pin' => $pincode));
$output = array();
if (count($data) > 0)
{
$output['village'] = $data->village;
$output['street'] = $data->street;
echo json_encode($output);
}
}
