session in php

26 Days Ago

i'm a newbie in php and maybe my question is so silly.

i tried to create a session in a file named login.php

 Help with Code Tags 
 PHP Syntax (Toggle Plain Text) 
<?php
include "koneksi.inc.php";
$name=$_POST['name'];
$password=$_POST['password'];
 
$hasil=mysql_query("SELECT * FROM TabelPegawai WHERE nama='$name' AND password='$password'");
$row=mysql_fetch_array($hasil);
 
if ($row[nama]==$name AND $row[password]==$password)
{
        session_start();
        $_SESSION['namauser']=$row[nama];
        $_SESSION['passuser']=$row[password];
        $_SESSION['level']=$row[jabatan];
 
	if($_SESSION['level']=="Manager")
		{header("location: manager.php");}
	else if($_SESSION['level']=="Kasir")
		{header("location:kasir.php");}
	else if($_SESSION['level']=="Gudang")
		{header("location:gudang.php");}
	else
		{header("location:http://www.google.com");}
}
else
       {header("location:http://www.yahoo.com");}
?>
<?php
include "koneksi.inc.php";
$name=$_POST['name'];
$password=$_POST['password'];

$hasil=mysql_query("SELECT * FROM TabelPegawai WHERE nama='$name' AND password='$password'");
$row=mysql_fetch_array($hasil);

if ($row[nama]==$name AND $row[password]==$password)
{
        session_start();
        $_SESSION['namauser']=$row[nama];
        $_SESSION['passuser']=$row[password];
        $_SESSION['level']=$row[jabatan];

	if($_SESSION['level']=="Manager")
		{header("location: manager.php");}
	else if($_SESSION['level']=="Kasir")
		{header("location:kasir.php");}
	else if($_SESSION['level']=="Gudang")
		{header("location:gudang.php");}
	else
		{header("location:http://www.google.com");}
}
else
       {header("location:http://www.yahoo.com");}
?>

but, $_SESSION['level'] is not recognized in other files like manager.php, gudang.php, and kasir.php

is there something wrong with my code?
thanks for your helps.

Did you start the session on all the pages where you need to access your session variables?

oh, it works if i start the session in every page that needs session variables. i also must start the session in a php file that destroy the session right? like this :

<?php
session_start();
session_destroy();
?>
<?php
session_start();
session_destroy();
?>

Yes but obviously, not until you are finished with it. You should also test whether a session has already been started or not before you try and start another one i.e.

if (!isset($_SESSION)) {
  session_start();
}
if (!isset($_SESSION)) {
  session_start();
}

You don't need to check. session_start() will not start a new session overwriting the old one. It just propagates.
session_destroy wouldn't be used very often, unless in a logout page or similar. You wouldn't have a session_start in this file as well (I don't think).

OK .. that's your choice. It is simply good practice.
