Warning: Cannot modify header information

Hello,
I'm getting this Warning: Cannot modify header information error just on the remote server when I click on the Add to cart button, and won't load the cart page. On the local server it looks ok. Can you help out? Thanks!

tende_ecart.php?categoria=tenda&style=Colors%20STYLE

the headers already sent error is caused by having output on the page before the header function is called.

in your case, you have the code for the ecart add to cart button behavior in the HTML body of the page.

the add to cart button code should be in the head of the page before the doctype tag, not in the HTML body.


by adding it in the HTML body, there is already HTML output to the page before the add to cart button calls the header function to perform the redirect. this is causing the error.

Thanx for your reply.
I put the ecart code within html because I had made a query within a query in order to show all the different product colours. Is there a workaround, maybe with ob_start? or javascript in order to load the cart page? The cart loads properly with all the selected products but it just won't load the cart page.

use another products recordset in the head of the page that will be used by eCart, that way eCart does not need to be in the body of the page.
