//pull in existing cart first!
$cart = $_SESSION['cart'];
$totalprice = 0;
if (count($fullproduct)){
if (isset($cart[$productid])){
$prevct = $cart[$productid]['count'];
$prevname = $cart[$productid]['name'];
$prevprice = $cart[$productid]['price'];
$cart[$productid] = array(
'name' => $prevname,
'price' => $prevprice,
'count' => $prevct + 1
);
}else{
$cart[$productid] = array(
'name' => $fullproduct['name'],
'price' => $fullproduct['price'],
'count' => 1

foreach ($cart as $id => $product){
$totalprice += $product['price'] * $product['count'];

and here is my javascript
Code: function jsUpdateCart(){
var parameter_string = '';
allNodes = document.getElementsByClassName("process");
for(i = 0; i < allNodes.length; i++) {
var tempid = allNodes[i].id;
var temp = new Array;
temp = tempid.split("_");
var real_id = temp[2];
var real_value = allNodes[i].value;
parameter_string += real_id +':'+real_value+',';
}
var params = 'ids='+parameter_string;
var ajax = new Ajax.Updater(
'ajax_msg','/shop/ajax_cart', {method:'post',parameters:params,onComplete:showMessage}
);
}
function showMessage(req){
$('ajax_msg')[removed] = req.responseText;
location.reload(true);
}
function jsRemoveProduct(id){
var params = 'id='+id;
var ajax = new Ajax.Updater(
'ajax_msg','/welcome/ajax_cart_remove', {method:'post',parameters:params,onComplete:showMessage}
);
}
When i press update or delete it doesn’t work. Could someone please tell me what’s wrong with my code? I'm already call this javascript in my template with this code
Code: < script type="text/javascript" src="<?php echo base_url();?>js/customtools.js"> < /script >
