Php Error when calling the cart() control function

krifur · November 17th, 2008, 01:46 PM

Hello,
If i understand everything

,when it call the cart() function from the controller,

Code:

    function cart($productid){
    if ($productid > 0) {

If customer click on add to cart then the $productid will be pass but this function is also dispyaing the content of the cart and this time the $productid is NULL (echo " ".anchor("shopping/cart","view cart");)

so this is causing two notice php error, i think i can find a way to fix but maybe i miss something here?
Any idea?
thx, and great book so far :)

I'm having this same issue. Anyone know what the problem is. It's the books code so it would be great if the author could pitch in to renedy this otherwise I, and others can't finish building the app.

Not sure if this helps, I can't remember if this fixed it when I was going through the book but I made a note on page 111 that where it says:

Code:

$nav['navlist'] = $this->MCats->getCategoriesNav();

it should read

Code:

$data['navlist'] = $this->MCats->getCategoriesNav();

I remember that this was the source of an error message I was getting but not sure if it the same one you are getting.

That's worked a treat. Thanks for that!!!!

In \system\application\models\morders.php, after //pull in existing cart first!
just put this line :

Code:

$cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : array();

It should look like this now :

Code:

function updateCart($productid,$fullproduct){
	//pull in existing cart first!
	$cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : array();

And no more "Undefined Index : cart" anymore !!!!

Quick reply. Haven't tried it yet but a big thanks!

Guys, I am so sorry. I've been answering questions via email. Yes on both counts, the $nav array should be $data, and yes, the original code has an isset() for the shopping cart, but didn't get inserted back into the text of the book.

if anyone wants to see my copy of the code, simply send an email to tom AT tripledogs DOT com. I will send you an archive.

Hi

Can you or anyone else please tell me how did you solve this problem?

I am trying to get around it, but I am unable to solve it?

I am getting those two errors thrown at my face again and again:

A PHP Error was encountered

Severity: Warning

Message: Missing argument 1 for Welcome::cart()

Filename: controllers/welcome.php

Line Number: 68

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: productid

Filename: controllers/welcome.php

Line Number: 70
