[PHP] Help Please?

[ThisNameWillDo!]

Hey, basically I have got a simple login script, but if I put any html above the PHP or I include the login page on another page, it comes up with the following error and it won't log me in:

Warning: Cannot modify header information - headers already sent by (output started at IREMOVEDTHIS/index.php:12) in IREMOVEDTHIS/login.php on line 28

Warning: Cannot modify header information - headers already sent by (output started at IREMOVEDTHIS/index.php:12) in IREMOVEDTHIS/login.php on line 29

Any idea how I can stop this? +Rep to any help

Thanks,
Vince.

All uses of header in php must be before anything is output to the client.

Thanks, but the lines that are causing the error are:

setcookie("id", $user[id],time()+(60*60*24*5), "/", "");
setcookie("pass", $user[password],time()+(60*60*24*5), "/", ""); 

I don't see how I can put this before where it is, because it happens when the user is logged in and needs to be where it is, is there any way I can change it so it doesn't cause that error?

It sets cookies, which requires headers being sent. Just put whatever html you want after the PHP. I can't really help futher unless you post the whole file as I don't see why it should be a problem to add your HTML after the PHP.

Okay thanks, I really appreciate your help In attempt to resolve this, I just put everything on the index file in PHP echo so that there's no HTML above any PHP, but now I can't get it to include files by doing <? include 'login.php'; ?> because it's all in echo ""; arghhh, is there any way i can get it to include a file when it's inside an echo :S

Why can't you just end the echo, include the file and then re-start it?..

As I've said before, without the full code it is going to be difficult to help you.

Well if you listen to what people have said, you would understand that you cant have any function placed after any data is sent to the browser (for example: HTML)

So setcookie, header, functions arent going to work and are going to throw a error (or a paddy)

So inorder to by pass this, any data you wish to send needs to be after the function is initiated.

Code #1

<?php
setcookie("id", $user[id],time()+(60*60*24*5), "/", "");
setcookie("pass", $user[password],time()+(60*60*24*5), "/", "");

echo 'Cookies set';

?>

Code #2

<?php
echo 'Setting cookies';

setcookie("id", $user[id],time()+(60*60*24*5), "/", "");
setcookie("pass", $user[password],time()+(60*60*24*5), "/", "");  

?>

Code #3

<?php
include 'loads_of_html.html';

setcookie("id", $user[id],time()+(60*60*24*5), "/", "");
setcookie("pass", $user[password],time()+(60*60*24*5), "/", "");  

echo 'Cookies set';
?>

Just so we're on the right lines, which ones do you think will work? (Without testing it)
