how to add input value from session using ajaxlink in yii - yii

Question

I am kind of lost on how to do this in my view.
I want to add the quantity. Right now, it adds but how do I get the input value into my ajaxlink?
My controller is using session to add.
<input id="quantity" type="text" value="1" class="span1">
<div id="cart-text">
<?php echo CHtml::ajaxLink(' Add ',
Yii::app()->createUrl('controller/basketAjax',array('id'=>$_GET['id'])),
array('success'=>'function(data){...
controller:
$session=new CHttpSession;
$session->open();
if (!isset(Yii::app()->session['cart']))
{
$quantity = 1;
$session->add('cart',array(
'product_id.'.$id=>array("id"=>$id,
'quantity'=>$quantity)
));
}
else
{
$cart = Yii::app()->session['cart'];
$array = $cart['product_id.'.$id];
if (isset($array)){
$array['quantity']=$array['quantity']+1;
} else {
$t = array('product_id.'.$id=>array("id"=>$id,'quantity'=>$quantity));
array_push($cart,$t);
}
$session->add('cart', $products);
}

Answer 1

you can do this by using keyup function of jquery. First set the id of link as "mylink". Compute the url by using createUrl.
<script type="text/javascript" >
$("#quantity").keyup(function(){
var url=<?php echo Yii::app()->createUrl('controller/basketAjax') ?>;
$("#mylink").attr("href","");
$("mylink").attr("href",url +$(this).val());
});
</script>
Now i explain whats happening above. first i catch the event keyup on input you are using. It will be called each time you press a key on input. Now url=<?php echo Yii::app()->createUrl('controller/basketAjax') ?>; this code is returning you the base url to your action without any parameters being passed.this line $("#mylink").attr("href",""); will set the href of your link to " "( means nothing). Now this line $("mylink").attr("href",url +$(this).val()); is appending the value of the input you are getting from the input.
Remember you have to put the separator in between like
$("mylink").attr("href",url+"/" +"id"+"/"+$(this).val());
Above i have assumed that the href in your case looks like "projectname/index.php/controller/action/id/something". Thats y i have used separators in between but you can customize it according to your needs.

ajaxLink will not work (from what I know), just build it the old fashion way with jquery. Your best solution is actually to put it in a form and submit the form. Something like
<?php
Yii::app()->clientScript->registerCoreScript('yiiactiveform');
$form=$this->beginWidget('CActiveForm', array('action'=>Yii::app()->createUrl('cart/addProduct')));?>
<input type="text" name="quantity" value="1">
<input type="hidden" name="Product_id" value="<?php echo $model->id;?>">
<?php echo CHtml::ajaxSubmitButton('Save',CHtml::normalizeUrl(array('cart/addProduct','render'=>true)),
array(
'dataType'=>'json',
'type'=>'post',
'success'=>'function(data) {
if(data.status=="success"){
$("#formResult").html("form submitted successfully.");
}
else{
$.each(data, function(key, val) {
$("#user-form #"+key+"_em_").text(val);
$("#user-form #"+key+"_em_").show();
});
}
}',
)); ?>
<?php $this->endWidget(); ?><!-- .contact -->
