Hello:

I am trying to add a small poll to my page and I am having a slight problem with the setting of the cookie, or so I think that is my problem. My idea of this working would be to see if the cookie was set (person answered the poll) or not. If it was answered, display the ads.php page. If it was not set, then display the poll.php page. I really do have everything working except when I try to set the cookie, it says errors with headers already sent. Can someone please help me with this. Also, because it is not working just yet, after the poll is completed, I want the ads.php to be loaded. Here are the files I have…

please, do not “dump” code.

Show us the relevant parts. If you’re not sure, describe the problem as clearly as possible, and link to the code elsewhere (e.g., make a gist on github).

when I try to set the cookie, it says errors with headers already sent

Have you done any research yet? It’s a very common problem. I’m sure you could find hundreds of answers on google just by copy+pasting the message.

There are two parts to a HTTP response: the headers, and the body. (Not to be confused with the <head> and <body> of an HTML document.) Cookies are a type of HTTP header. The headers must be sent first:. this means as soon as you send regular output (which goes in the body), the headers must be sent, and you can’t send any more afterwards. Any output counts, even (for example) whitespace or a BOM.
