Cannot add product to shopping cart

[Guest]

I get the following errors when trying to add a product to my shopping cart:

 

 

Notice: Undefined index: id in /home/waterloo/public_html/k-wbookworm.com/catalog/includes/application_top.php on line 374

 

Notice: Undefined index: id in /home/waterloo/public_html/k-wbookworm.com/catalog/includes/application_top.php on line 374

 

Warning: Cannot modify header information - headers already sent by (output started at /home/waterloo/public_html/k-wbookworm.com/catalog/includes/application_top.php:374) in /home/waterloo/public_html/k-wbookworm.com/catalog/includes/functions/general.php on line 33

 

Not sure why.

This only happens from the product's page. I tried to add from the New Products page and all worked fine.

Don't personally know much php, but a quick google search came up with this http://www.oscommerce.com/forums/topic/156547-header-errors-please-help/ not saying it will help but it never hurts to try.

No, does not pertain to my issue. No whitespace found.

Here are the lines causing the error:

 

 

// customer adds a product from the products page

case 'add_product' : if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {

$cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], HTTP_POST_VARS['id']))+1, $HTTP_POST_VARS['id']);

}

tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));

break;

 

Please note that the product does actually get added, then the error codes are displayed.
