I have a very simple login script , my problem is that I have no idea how to display my [b]index.php[/b] once the user has successfully logged in. Please will someone be able to assist. Thank you for all your help so far , it is much appreciated.

Regards.

[b]main_login.php[/b]
























Member Login
Username:
Password:
  
[b]
checklogin.php[/b]

<?php
ob_start();
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // 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'];

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($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";

    You can redirect there from your login_success.php. You can either redirect using header(), or if you want to show the 'login successful' first, use a HTML META tag with REFRESH attribute.

    One option would be to use the index.php as just a controller page and then pass parameters (current_page) to this page in the post or get fields.
    $_REQUEST["current_page"] = "{what ever page u want to go to}"
    the index.php would

    have function that check that the user is logged in (using a session)

    $task = check_user_login();

    $d_file = sprintf($file_path."%s.php",$task);

    if(file_exists($d_file)){
    include $d_file;
    }else{
    include($file_path."php_files/error.php");
    }
    exit(0);
    function check_user_login(){
    if(isset($_SESSION[user_token])){
    $task = $task // what ever task was passed in in the first place
    }else{
    $task= logout; // destroy all session values
    }

    if(!allowed_actions()){ // always good to check if the current user has permission to perform the task or view the page.
    task = logout;
    }
    return task;
    }

    so for ur login, $_REQUEST["current_page"] = "login". after the login form has been processed, u just redirect to the index.page using ur redirect function.

    One more thing after u redirect a page, always exit(); so it would be best to wrap the header(location:) inside a function.

    Hope this help, I know it might not be too clear. send me an email if you want more clarification.
