[RESOLVED] sessions and cookies in one page.

dougal85

Am i right in thinking that you need to do start_session() and setcookie() before headers are sent?

and they also set headers when you use them?

soo... how do i set a cookie on a page that's already using sessions?

In response to both of your first two questions: yes.

In the same way you use sessions... just put the setcookie() call (in addition to the session_start() call, of course) before any data is outputted (which causes HTTP headers to be sent and set in stone). Before you output data, HTTP headers are completely in your (the server's) hands to modify however you please.

ok thanks, i thought that when you used one it set the headers and then meant you couldnt use the other (that did seem silly i know) ... so it seems ive got something outputting that ive not realised... interesting...

the hunt begins.

What makes you think that? If headers are already sent, and you try to use setcookie(), PHP will detect this and tell you what line of what file started output (meaning there shouldn't really be any guesswork or 'hunting' to find the culprit).
