Hi all,

I got this problem. I just started using session in my page. The this is, its my first time to use it. When I opened the page, the error is:

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\web\apds new\html\Athlete_Info.php:1) in c:\web\apds new\html\Athlete_Info.php on line 398

Warning: Cannot modify header information - headers already sent by (output started at c:\web\apds new\html\Athlete_Info.php:1) in c:\web\apds new\html\Athlete_Info.php on line 400



Here is my code: Athlete_Info.php

Code:

    if (mysql_num_rows($result) ==0) {
      echo "Can not find record.";
    }
    else {
       // display the result
       while ($row=mysql_fetch_assoc($result)){

        // Start the session, register the values & redirect.
	session_name ('YourVisitID');
	ini_set ('session.use_cookies', 0);
	session_start();  // this is line 398
	$_SESSION['Student_number'] = $row['studno'];
	header ("Location:  http://" . $_SERVER['HTTP_HOST']    . dirname($_SERVER['PHP_SELF']) . "/Athlete_Info.php?" . SID); // this is line 400
	exit();

       echo    $student_number = $row['StudNo'];
       echo    $last_name = $row['lname'];
       echo    $first_name = $row['fname'];
       echo    $middle_name = $row['mname'];
       echo    $nick_name = $row['nname'];
       echo    $present_address = $row['presentadd'];
       echo    $course = $row['course'];
       }
    }

What is wrong with my code? I don't understand the meaning of this Warning message. Can can somebody explain it to me?. Any help is very much appreciated.

Starting a session occurs before anything is outputted to the screen...Jose

Thanks for the tip alabaster_lynch, I'll try moving my session_start() on top and see if it works.

I tried to move the session_start() and the first WARNING disappeared thanks for the help. But the second warning is still there. can you explain what is the meaning of the second warning?

header ("Location: http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . "/Athlete_Info.php?" . SID); // this is line 400

if you want to have header information further down in the page, you need to put ob_start(); at the top of the page with session_start(), this will fix your redirect problem
