I have been stuck on this session error for a day now and have tried a million different techniques to try and solve it.
Basically when the session is empty or a new request to the page there is no data in the session variable which means as I load the page it is giving the following errors:
Message: Undefined index: totalprice
Filename: main/cart.php
Line Number: 4,
Severity: Notice
Message: Undefined index: cart
Filename: main/cart.php,
Message: Undefined index: cart
Filename: controllers/welcome.php
Line Number: 79,
It is the code from the wrox book professional codeigniter, i have already read the posts on here but they do not answer my problem I have tried again and again but still nothing so someone please help on this one..
Controller
Code:
function cart($productid = -1) {
if ($productid > 0){
$fullproduct = $this->MCart->getProduct($productid);
$this->MCart->updateCart($productid,$fullproduct);
redirect('welcome/paving_stone/'.$productid, 'refresh');
} else {
$data['title'] = "Venus Stone | Shopping Cart";
if (count($_SESSION['cart']) == true) {
$data['cats'] = $this->MCats->getTopCategories();
$data['main'] = 'cart';
$this->load->vars($data);
$this->load->view('index');
} else {
$data['cats'] = $this->MCats->getTopCategories();
$data['main'] = 'cart';
$this->load->vars($data);
$this->load->view('index');
$this->session->set_flashdata('conf_msg', "Your Cart Is Empty.");
}
}
}
Model
Code:
function updateCart($productid,$fullproduct){
$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'];
}
$_SESSION['totalprice'] = $this->format_currency($totalprice);
$_SESSION['cart'] = $cart;
$this->session->set_flashdata('conf_msg', "We've added this product to your cart.");
}
}
So if anyone has a clue please enlighten me...
If you add a product to the cart the error then stops as it has started a valid session with the variables inside..
Not had a great deal of experience dealing with session data so if some kind person would point me in the right direction I would be ever so grateful...
Thanks in advance Paul
