ajax_cart_remove Firefox ve IE çalışır, ancak güncelleme Firefox ile çalışır, ancak IE 7/8 ile değil.
Herkes bana bazı öneriler verebilir misiniz.
Sen orijinal prototype code here görebilirsiniz.
kontrolörleri ajax_cart ve ajax_cart_remove şunlardır.
function ajax_cart(){
$this->MOrders->updateCartAjax($this->input->post('ids'));
}
function ajax_cart_remove(){
$this->MOrders->removeLineItem($this->input->post('id'));
}
Ve Moders için modelleri takip ediyoruz.
function removeLineItem($id){
$id = id_clean($id);
$totalprice = 0;
$cart = $_SESSION['cart'];
if (isset($cart[$id])){
unset($cart[$id]);
foreach ($cart as $id => $product){
$totalprice += $product['price'] * $product['count'];
}
$_SESSION['totalprice'] = $this->format_currency($totalprice);
$_SESSION['cart'] = $cart;
echo "Product removed.";
}else{
echo "Product not in cart!";
}
}
function updateCartAjax($idlist){
$cart = $_SESSION['cart'];
$records = explode(',',$idlist);
$updated = 0;
$totalprice = $_SESSION['totalprice'];
if (count($records)){
foreach ($records as $record){
if (strlen($record)){
$fields = explode(":",$record);
$id = id_clean($fields[0]);
$ct = $fields[1];
if ($ct > 0 && $ct != $cart[$id]['count']){
$cart[$id]['count'] = $ct;
$updated++;
}elseif ($ct == 0){
unset($cart[$id]);
$updated++;
}
}
}
if ($updated){
$totalprice=0;
foreach ($cart as $id => $product){
$totalprice += $product['price'] * $product['count'];
}
$_SESSION['totalprice'] = $this->format_currency($totalprice);
$_SESSION['cart'] = $cart;
switch ($updated){
case 0:
$string = "No records";
break;
case 1:
$string = "$updated record";
break;
default:
$string = "$updated records";
break;
}
echo "$string updated";
}else{
echo "No changes detected";
}
}else{
echo "Nothing to update";
}
}
