[SOLVED] Cannot modify header information error..

[sspoke]

Hello im having this error on atleast 5 pages (login,register,inside logged in page,forgotpassword) and it doesn't seem to redirect after seccessful login or register etc..

 

Warning: Cannot modify header information - headers already sent by (output started at C:\shttps\www\newproject\utils.php:70) in C:\www\newproject\mysession.php on line 85

 

Warning: Cannot modify header information - headers already sent by (output started at C:\shttps\www\newproject\utils.php:70) in C:\www\newproject\register.php on line 95

 

I know headers have to be first of any page but this worked yesterday I did no changes at all expect for defining new database settings and new host..

 

 

it says output started at utlis.php line 70 but that script edits at line 68 with a ?>  ..

 

mysession.php line 85 is     

setcookie("sessionid",$sessionid,0,'/','',0);

 

register is the page im calling and it starts off line this

 

<? 
require_once("alldefines.php");
require_once("mysession.php");

and line 95 is where error on register.php is

 

95.   			header("Location: " . REGISTER_DONE);
96.    			return;
97.    		}
98.		}
99.		break;
100.	}

?>

 

 

alldefines.php has

 

define(REGISTER_DONE,"registerc.php");

 

I been trying to fix it but no progress its....

 

well any help would help possibly

Have you tried buffering the output ? If there is any HTML or anything echoed to the browser before the header() call, the header will not redirect (becasuse at that point the header has been sent to the browser).

 

Try adding:

ob_start();

 

to he first line of your script. And also check any required/included scripts to make sure they do not echo or print anything to the browser before your header() call.

mysession.php has no echos just a bunch of functions  definings only has define()'s no html no echos

 

only include in mysessions.php is definings and utils i commented out ultils include and removed all its calls and still errors

[sspoke]

Says I cant edit my last reply.. anyways I wanted to add that out of the 2 modify header information - header already errors

 

removing the

 

  //  setcookie("sessionid",$sessionid,0,'/','',0);

 

removes one of the 2 errors.. but how is setcookie related its needed and I dont see any way around it

[wildteen88]

The cause of the error is on line 70 in utils.php as indicated by the error message (important bits highlighted in red).

 

Warning: Cannot modify header information - headers already sent by (output started at C:\shttps\www\newproject\utils.php:70) in C:\www\newproject\mysession.php on line 85

 

 

The problem is not with mysession.php, but utils.php. Also the other errors you are getting are caused by the first error. SO if you fix the first error message then all other errors will go away

 

Post lines 65 - 75 here from utils.php.

You dont need to edit the title to mark it solved any more. Just mark it solved by clicking the Solved button at the bottom of the page before the quick reply box and it does it for you. Looks like some one has already done it for you.
