Making a Login Work After Cache, Cookies, etc. Have Been Cleared
- by John
Hello,
I am using the code below for a user login. The first I try to login after cache / cookies, etc. have been cleared, the browser refreshes and the user name is not logged in. After that, logging in works fine.
Any idea how I can make it work the first time?
Thanks in advance,
John
index.php:
<?php
if($_SERVER['REQUEST_METHOD'] == "POST"){header('Location: http://www...com/.../index.php?username='.$username.'&password='.$password.'');}
require_once "header.php";
include "login.php";
require_once "footer.php";
?>
login.php:
<?php
if (!isLoggedIn())
{
if (isset($_POST['cmdlogin']))
{
if (checkLogin($_POST['username'], $_POST['password']))
{
show_userbox();
} else
{
echo "Incorrect Login information !";
show_loginform();
}
} else
{
show_loginform();
}
} else
{
show_userbox();
}
?>
show_loginform function:
function show_loginform($disabled = false)
{
echo '<form name="login-form" id="login-form" method="post" action="./index.php?'.$_SERVER['QUERY_STRING'].'">
