Page Redirection Problem :(

[chinmay235]

I have faced some problem while i am login my account.

Please check my code.

Code Select Expand


<?php
include('forum/SSI.php');
$_SESSION['login_url']='http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']; //http://localhost/2015/myproject/index.php
$_SESSION['logout_url']='http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']; //http://localhost/2015/myproject/index.php
//print_r($_SESSION);exit;
ssi_login();
ssi_logout();
?>




Above code is working fine and page redirected successfully my current page while i am giving correct information.

But when i am giving wrong username and password. Page redirect to the forum log-in page http://localhost/2015/myproject/forum/index.php?action=login2 [nofollow] I want to show error message in the same page.

How i am showing the error message in my current page?

First things first, you don't need to write to $_SESSION, the function does that for you.

You can call both ssi_login and ssi_logout with a parameter $redirect_to, eg:
ssi_login($redirect_to = 'http://localhost/2015/myproject/index.php');

About your issue, there's really not much that can be done via SSI, I'm sorry. The function sends the login data to SMF's "login2" action and, in that, when you fail the login, you are sent to SMF's login page...

You might get luckier by using the SMF API developed by Andre N, although it is not so simple to use...

Up

Recently I looking for this too, about how error message from login2 can back to same page using SSI, but no fixes yet.

So I make my own fix.
For example, I make chat.php which is outside SMF.

Look at this code from Sources/LogInOut.php:

Code Select Expand

// You forgot to type your username, dummy!
if (!isset($_POST['user']) || $_POST['user'] == '')
{

Then add after it:

Code Select Expand

if (strstr($_SERVER['HTTP_REFERER'], 'pokemonstars.com/forum/chat.php') !== false) {
    header('Location: http://pokemonstars.com/forum/chat.php?error=nouser');
}

Change the URL to your current page. Try login without username and password.
It should work back to your current page.

You'll also need some $_GET to your current page to show the error message.

Code Select Expand

if ($_GET['error'] == "nouser")
echo "Username is empty";

User filled but pass is empty.

Code Select Expand

// Hmm... maybe 'admin' will login with no password. Uhh... NO!
if ((!isset($_POST['passwrd']) || $_POST['passwrd'] == '') && (!isset($_POST['hash_passwrd']) || strlen($_POST['hash_passwrd']) != 40))
{
if (strstr($_SERVER['HTTP_REFERER'], 'pokemonstars.com/forum/chat.php') !== false) {
    header('Location: http://pokemonstars.com/forum/chat.php?error=nopass');
}
$context['login_errors'] = array($txt['no_password']);
return;
}

User is not exist

Code Select Expand

// Let them try again, it didn't match anything...
if ($smcFunc['db_num_rows']($request) == 0)
{
if (strstr($_SERVER['HTTP_REFERER'], 'pokemonstars.com/forum/chat.php') !== false) {
    header('Location: http://pokemonstars.com/forum/chat.php?error=usernoexist');
}
$context['login_errors'] = array($txt['username_no_exist']);
return;
}

Wrong password

Code Select Expand

// We'll give you another chance...
else
{

// Log an error so we know that it didn't go well in the error log.
log_error($txt['incorrect_password'] . ' - <span class="remove">' . $user_settings['member_name'] . '</span>', 'user');
if (strstr($_SERVER['HTTP_REFERER'], 'pokemonstars.com/forum/chat.php') !== false) {
    header('Location: http://pokemonstars.com/forum/chat.php?error=incorrectpass');
}
$context['login_errors'] = array($txt['incorrect_password']);
return;
