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