Hey guys, im doing a form login script using mysql. Im using a class file that i wrote to store all of my mysql prodecures.
Now i got this error after parsing in all of my login stuff. The script works basically but im wonderin what do these error's mean?

session_start() must be the first line of your code

well whats on line 51 and 59?

the "headers already sent" message means that you've started outputting the page itself. the headers must be sent before any other data. that seems to be what you're doing wrong.

[edit] the error msgs says output started at index.php:7, which means line 7. I would check what's on line 7 if I were you

Well...line 7 is my < ?php tag.
haha..

hm..i dont get ya snake. care to explain? the part about the headers

The lines before your <?php tag need to be blank if you use session_start() later.

SnakeBite · March 25th, 2004

that's right. iirc, there's a blank line between the headers and the document itself. iow, you would have to do ALL header-stuff BEFORE outputting ANY data.

[edit] that means all non-php code too. at the begnning of your page, you must start with the php tag, then do all your header work before you start outputting any data.

session calls are headers instuctions

you can't send an header after outputting something...
so you must do all this php stuff at the top of the page..
no spaces before the "< ?php" tag and no echoes

that's what I'm trying to say. NO output until you're done with the headers.
