Hi,
Could anyone please tell me how to go about linking some folders which are already in php to the login page. For example once you have logged in successfully, the next thing you want to see is the admin homepage. How do you link the login page to the admin page and then from the admin page to the student page etc. Please i would be greatful if anyone could provide the code. This is my code for both the checklogin.php and login_success.php
checklogin.php
<?php
ob_start();
$host="localhost"; // Host name
$username="root"; // Mysql username
$password="abby1"; // Mysql password
$db_name="test"; // Database name
$tbl_name="members"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Define $myusername and $mypassword
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
ob_end_flush();
?>
login_success.php
<?
// Check if session is not registered , redirect back to main page.
// Put this code in first line of web page.
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>
<html>
<body>
Login Successful
</body>
</html>

Using menus ? If a user is valid, redirect him to the next page which has a menu to navigate to all the pages. You can use the same header function to redirect the user after successful login.
In adminpage.php, have a menu to navigate to other pages.

yep.
header("location: $url");
where $url can be
1. A url eg. $url="http://www.yahoo.com";
2. The screen where you want to redirect the user.
Eg. $url="path/to/admin/index.php";
header("location: $url");

Oh btw, you cant give localhost. You should give the relative path. For example, if your executing script is in webpaos and you want to redirect the user to admin/index.php, you can do it this way.
header("location: ./admin/index.php"); Ignorance is definitely not bliss!

Umm.. Did it solve your problem ? And yep! dont give the absolute path. If you host this site some day, you should search for localhost in your script and change it to the url. So, its better if you give relative path of the file.

if(!session_is_registered(myusername)){
header("location:main_login.php");
}
session_destroy();
?>
