Browsers and Variables.

nova

I have a shopping cart script which adds to a list and allows people to select item numbers in small input boxes. The cart can be checked out here:

www.assetguard.ws/services.html

Everything works flawlessly in IE and Netscape, but for some reason it doesnt work in AOL 7.0. According to some testers, the variable ammount is returned as 0, instead of the ammount of items chosen, and in turn an error message is discplayed instead of checking the person out.

Each item has a PIN number, and when it is added to the cart, a small input box is generated with the number 1 as default. At checkout, if you set this to 0, or anything other than 1 and above, it gives you an error message.

The name of this field is generated with PHP. Its basicaly get "x" and add the PIN number to the end for each item. So for item 10, the input box code would be:

<input name=x10 value=1 size=2>

Now the the only thing that determines wether $ammount is 0 or other, is on the checkout.php itself. The code is this:

      $x = "x".$rpin;
      $ammount = (int)$$x;

Im thinking maybe its the double variable. Any help would be appreciated.

surely this should be

$$x = "x".$rpin;
      $ammount = (int)$$x;

note the double $ on the first x - it is a variable variable.

No, $x = "x".$rpin; because thats the name of the input box on the previous page. $$x is the variable with the name "x".$rpin.

Anyway..

I redid my coding a little. I made it so that the PIN number which is an integer runs through chr() and turns into a letter. Just incase AOL doesnt like numbers.

$pinint = $row[pin] + 96;
$pins = chr($pinint);

Then on the next page, i used this code to read the variable.

$rpinx = $rpin + 96;
$rpins = chr($rpinx);
$ammount = (int)$$rpins;

It works in mozilla, IE, and netscape, but I am not sure about AOL. I do not have AOL, so could someone with it please do me a favour and just check if you can add, and get to the checkout page without any errors? Because if there is an error, i will suspect the double variable, even tho it should now have any affect...

Thank you.
