I really need help with this shopping cart!!

Can someone please help me? I am trying to build a shopping cart for a class project that is due next week and can't seem to get it working properly. I have attached a zip file with 3 files inside. Could someone please please please take a look at them and tell me what I am doing wrong (or right, whichever is less)?

You can take a look at what I have so far by going to www.whatnott.com/project/products2.php

It will put the items in the cart but doesn't display the price or totals for each product or overall total. Nor does it display the product name selected. It just displays $0.00.

The update button doesn't work either, if I try to get rid of one by putting the qty to '0' and hitting update, it just puts the qty back to '1'. Also, if you click refresh or go back to the previous page and then back to the shopping cart using the arrows on your browser, it increments the qty by 1 every time.

I really hope someone can help me out here.

Thanks in advance.

@ $new = $HTTP_GET_VARS['prodID'];

you are posting the prodID so you should use @ $new = $HTTP_POST_VARS['prodID'];

also , depending on your version of php its better to use

$GET instead of $HTTP_GET_VARS
$POST instead of $HTTP_POST_VARS
$_SESSION instead of $HTTP_SESSION_VARS

lemme know if it works

nope, I still get the exact same results. It isn't pulling the product name or price and the update section doesn't work either. I am using a php and mySQL web development book shopping cart example and trying to make it my own. There are functions in it that i have left out because it uses categories. Depending on the category selected, it then does a query on books by $isbn to display the results. Which I don't have categories of products.

I have the query on the products working fine. It is basically just not posting the product name and price using the key and value of $prodID and $prodQty.

It also shows in the book to append the $prodID to the end of the url when calling the view_shopping_cart.php page. I tried doing it like the book shows by doing this: /view_shopping_cart.php?new=$prodID and getting rid of the hidden fields, but when I do that, it never adds anything to the cart, just keeps displaying that the cart is empty.

So the only way I have found to pass it is by using a hidden field like this: <input type='hidden' name='prodID' value=".$prodID.">

Only thing is that then I have to change @ $new= $GET['prodID']; to @ $prodID = $GET['prodID']; It also won't display anything if I use $POST instead of $GET.

I am totally lost.

Thanks for your help.

Okay, I'm starting to get it worked out. I can get it to display the product name and price now. I only have 7 products in the db to display. However, no matter which product I select to add to the cart from the product list, it always displays the name and price of the last product on the list in the shopping cart. So if I selected the first or second product on the list, it will display the seventh product in the shopping cart.

The total per item seems to be working but the overall total is not, nor is the update section.

I would really appreciate it if someone could take a look at what I have and see if you can help me out. I have attached an updated .zip with the changes added since the last time I posted it.

You can take a look at it in action by going to www.whatnott.com/project/products2.php

Thanks again in advance.
