Digitalpoint would know. He's pretty awesome with code.

I know what it means.. but it wont help you..
why its there is problem..

what its doing is sending headers after output has been started.. not sure how to fix it... never delt with osCommerce before.. paste general.php lines 1250-1270 and ill try to help

Basically means the system is trying to set something in the HTTP headers (since it's within the sessions.php file, I would guess it's a cookie or something along those lines).

The problem is that the request to the cart has already spit something out to the browser (which started in general.php).

And since you have to send the HTTP headers before you can send anything else to the user's browser, once you spew something out, the HTTP headers are sent at that point (and can't go back and be changed).

Truthfully, it probably would not be terribly difficult to debug. osCommerce has a pretty clean (from a coding standpoint) foundation to start with.

So, what should I do?

Looks like it's been answered several times on their support forum.

digitalpoint · 01-20-2004, 04:56 PM

Well, if you can't find an answer in their forums or anywhere else, let me know... I'll be happy to have a look at it for you...

I found a post over there that helped. I had white space after the ?> on one of the pages. Got rid of it and everything works now.

Thanks

Annoying when it's something as simple as that, eh?

Yea, I had no idea that white space at the end of the page could hurt anything. Guess I know now

The number ONE error for headers already sent in oscommerce is a blank line at the end of the file. I've seen it so many times I know it by heart

I have around 10 OsC sites running. if you customize then alot you get use to seeing that error

Would you belive i was going to suggest you look for extra lines after the ending php tag?

I have seen the same "headers already sent" message on multiple scripts including gallery scripts, phpbb and other php scripts. Often this line is added at the end of the file when its edited by cpanels file manager.

Solution: In your /catalog/includes/configure.php at the very bottom
configure your shopping cart to save sessions in your database (mysql)
instead of the default /tmp

Yes, error messages were sent from general.php before the cart could be displayed.
