setcookie problems!

oPt1k

Hello, I used the totally secure auth system that was on this site, and I’m having 1 problem.

After you register for an account, wait for the email, activate it, then try to login. You get this error after you click submit to login with your details.

Warning: Cannot modify header information - headers already sent by (output started at /home/camkb/public_html/index.php:41) in /home/camkb/public_html/modules/auth/user.php on line 86

Warning: Cannot modify header information - headers already sent by (output started at /home/camkb/public_html/index.php:41) in /home/camkb/public_html/modules/auth/user.php on line 87

on line 86 and 97, there is 2 set cookie functions.

setcookie('user_name',$user_name,(time()+2592000),'/','',0);
setcookie('id_hash',$id_hash,(time()+2592000),'/','',0);

Any help would be greatly appreciated.
Thanks.

Try sending the cookies after you send your headers. Cookies are actually headers, too.

You should also look at this:
output started at /home/camkb/public_html/index.php:41

This is where the output of headers start (usually echo'ing html), and no additional headers may be sent after this line.

just make sure that you send headers (including cookies) as the first thing in the file - i.e. before the <html> tag - right at the top of the page.

alright, ive tried a few different way at getting around it, none worked.

Someone suggested that i tried useing JavaScript to set the cookies. I was just wondering at how i would go about doing this?

here are the 2 functions with the setcookie function in them. Any help would be greatly appreciated.

function user_logout() {
	setcookie('user_name','',(time()+2592000),'/','',0);
	setcookie('id_hash','',(time()+2592000),'/','',0);
}

function user_set_tokens($user_name_in) {
	global $hidden_hash_var,$user_name,$id_hash;
	if (!$user_name_in) {
		$feedback .=  ' ERROR - User Name Missing When Setting Tokens ';
		return false;
	}
	$user_name=strtolower($user_name_in);
	$id_hash= md5($user_name.$hidden_hash_var);

setcookie('user_name',$user_name,(time()+2592000),'/','',0);
setcookie('id_hash',$id_hash,(time()+2592000),'/','',0);
}

you have to set the cookies at the beginning of the script and nowhere else - and not in a function. if you are taking user data on that page, process it on the next one and set the cookies there.

my site doesn't work that way! everything runs through the index.php!

it will work through the javascript cookies i just need someone to explain to me how to go about doing it

you'd be better checking a javascript forum for that - most here tend (not surprisingly) to be php bods, so if you're not going to be using php for it you may find answers difficult to come by.

i figured it out anyway

php.net/manual = the new bible!

a good old "ob" does the trick!

ob_start();
	echo "Hello\n";
	setcookie('user_name',$user_name,(time()+2592000),'/','',0);
	setcookie('id_hash',$id_hash,(time()+2592000),'/','',0);
	ob_end_clean();
