Session Error in PHP

Randhy · October 23rd, 2004, 01:09 AM

I have a problem with my session in PHP with code like these :
cek_login.php

<?
 session_start();
 session_register("username");
 if ((!$username) or (!$pass))
 {
 echo "Login tidak lengkap ";
 }
 else
 {
 $koneksi = mysql_connect("localhost", "", "") or die (mysql_error());
 mysql_select_db("latihan_php");
 $passwd = md5($pass);
 $query_login = mysql_query("select count(*) as login from anggota where username= '$username' and pass = '$passwd'") or die (mysql_error());
 $row = mysql_fetch_array($query_login);
 if ($row["login"] == "1")
 {
 session_register("username");
 header("location:member.php");
 }
 else
 {
 header("location:non_member.php");
 }
 }
?>

When I login form login.html and click submit button there are error messages like these :

Warning: Cannot send session cookie - headers already sent by (output started at C:\apache\htdocs\latihan_session\cek_login.php:12) in C:\apache\htdocs\latihan_session\cek_login.php on line 13

Warning: Cannot send session cache limiter - headers already sent (output started at C:\apache\htdocs\latihan_session\cek_login.php:12) in C:\apache\htdocs\latihan_session\cek_login.php on line 13

Some one help me, please !!!!

Are there any lines left above the code that you posted here? If so, move the session_start(); to the top of this page. This should be the first line of code on your page.

Try this simple example.

Code:

<?
session_start();
$_SESSION['abc'] = "hello world";?>
<html>
<head>
<title>test session</title>
</head>
<body>
<? echo "The content of sess variable is $_SESSION['abc']";?>
</body>
</html>

Try to play around with this by adding some lines on top of this page and see how that behaves.

Hope that helps.
Cheers!

What is the OS that you use? Unix/linux/Windows?

Windows XP Professional edition.

Okay, look for php.ini under PHP installed folder, and that should be having session.save_path that defaults to the UNIX '/tmp' folder, which you got to uncomment(if commented) and change it to point to Windows TEMP folder.

That should solve this problem.

Cheers!

I have replaced the value of session.save_path to be : C:\Documents and Settings\mahasiswa\Local Settings\Temporary Internet Files, but the cookie is still have errors.

Warning: Cannot send session cookie - headers already sent by (output started at C:\apache\htdocs\latihan_session\cek_login.php:12) in C:\apache\htdocs\latihan_session\cek_login.php on line 13

Warning: Cannot send session cache limiter - headers already sent (output started at C:\apache\htdocs\latihan_session\cek_login.php:12) in C:\apache\htdocs\latihan_session\cek_login.php on line 13

So you are out of that error now.

setcookie() defines a cookie to be sent along with the rest of the
header information. Cookies must be sent before any other headers are
sent (this is a restriction of cookies, not PHP). This requires you to place calls to this function before any <html> or <head> tags.

And see to that you don't leave unnecessary extra carriage returns at the top.

Hope that helps.
Cheers!
