Did you even read your code? You call session_start(), then immediately you call session_destroy(), then you call session_start() yet again.

trecool999 · October 6, 2008

Why are you starting a session, then destroying it and starting it again? Why not just use session_unset?

genericnumber1 · October 6, 2008

do you have any line breaks above the <?php in the file?

and as he said, your code is.. messy

OriginalBoy · October 6, 2008

I got it made for me by a friend I don't know anything about sessions

DarkWater · October 6, 2008

It appears that your friend doesn't either.

OriginalBoy · October 6, 2008

He does he just did it in a rush or maybe I put it together wrong....

Can someone help me fix this?

We already told you. Remove every session_* function in there, and just put ONE session_start() ABOVE the first include.

Can I see your new code? That second error will go away when the first one's fixed, btw.

Put session_start(); as your first line of code. Then read the error and see what it's telling you for where output was started.

revraz · October 6, 2008

Also, this code at line 87 wont work

header("location:./?page=register&register=success");

You've already sent output to the browser. Use a HTML or Javascript redirect.

Nah, the output is from PHP sending out the error from the session. The header() redirect should be fine after the sessions are sorted out.
