The exact way of adding item to the Cart is like follows its an ajax call function .

var data = "quantity[]="+qty+"&virtuemart_product_id[]="+pid
    //data      =   encodeURIComponent(data);
    jQuery.ajax({               

                    type: "GET",
                                    dataType: 'json',
                    url: "index.php?option=com_virtuemart&nosef=1&view=cart&task=addJS",
                    data: data,
                    success: function(data) {
                        alert(data);
                    }
         });

If you want to do it from php section go to the cart controller file and check function addJS then pass the corresponding param to that function.

Hope this may help you..

Please use the VirtueMart API for correct cart handling. http://forum.virtuemart.net/index.php?topic=125870.msg431290#msg431290

In short, VirtueMart uses by default a call done with jQuery.getJSON which is a shorthand for an Ajax function. So all this above is not necessary. In doubt it is also unsecure. You should use the VM API to retrieve and store the cart object.
