Redirect user after login

[Julian F]

Hello,
How can I make DoLogin() redirect user to custom URL, I use this function to login user from Facebook social login

Code Select Expand


if ($user_info['is_guest'])
  {
  require_once($sourcedir . '/LogInOut.php');
  $modSettings['cookieTime'] = 3153600;
  DoLogin();
  }

Any help will be appreciated .
Thank you.

what is doLogin()?

the SSI login function (in theory) allowed for the redirect... but doLogin is not an SMF function at all -- you would probably have to ask the mod author

[Suki]

DoLogin()'s only job its to set up the cookie and check if the user isn't banned.  It has a hardcoded redirectexit() call so you cannot make it to redirect the user wherever you want it.

The easiest way its to just clone that function and remove the parts you don't need, of course thats just a wild guest since I have no idea on what you are trying to achieve.

thanks Suki!

Thank you Suki for your replay,
Can you please tell me witch line from this code  make that redirectexit??

function DoLogin()

// Get ready to set the cookie...
$username = $user_settings['member_name'];
$user_info['id'] = $user_settings['id_member'];

// Bam!  Cookie set.  A session too, just in case.
setLoginCookie(60 * $modSettings['cookieTime'], $user_settings['id_member'], sha1($user_settings['passwd'] . $user_settings['password_salt']));

// Reset the login threshold.
if (isset($_SESSION['failed_login']))
unset($_SESSION['failed_login']);

$user_info['is_guest'] = false;

{
$_SESSION['admin_time'] = time();
unset($_SESSION['just_registered']);
}

// Don't stick the language or theme after this point.
unset($_SESSION['language'], $_SESSION['id_theme']);

// First login?
$request = $smcFunc['db_query']('', '
SELECT last_login
FROM {db_prefix}members
WHERE id_member = {int:id_member}
AND last_login = 0',
array(
'id_member' => $user_info['id'],
)
);
if ($smcFunc['db_num_rows']($request) == 1)
$_SESSION['first_login'] = true;
else
unset($_SESSION['first_login']);
$smcFunc['db_free_result']($request);

// You've logged in, haven't you?
updateMemberData($user_info['id'], array('last_login' => time(), 'member_ip' => $user_info['ip'], 'member_ip2' => $_SERVER['BAN_CHECK_IP']));

// Get rid of the online entry for that old guest....
$smcFunc['db_query']('', '
DELETE FROM {db_prefix}log_online
WHERE session = {string:session}',
array(
'session' => 'ip' . $user_info['ip'],
)
);
$_SESSION['log_time'] = 0;

// Just log you back out if it's in maintenance mode and you AREN'T an admin.
if (empty($maintenance) || allowedTo('admin_forum'))
redirectexit('action=login2;sa=check;member=' . $user_info['id'], $context['server']['needs_login_fix']);
else
redirectexit('action=logout;' . $context['session_var'] . '=' . $context['session_id'], $context['server']['needs_login_fix']);

}

What i want to do is to make this mod  http://www.smfpacks.com/sociallogin/ [nofollow] to redirect after login to custom link stored in session.

Do note what Suki said:

since I have no idea on what you are trying to achieve.

Why don't you provide some further detail?
What, specifically, are you trying to accomplish?

[Julian F]

I have provide more details in my previews replay. Check it please.

Here is the login function for facebook

Am not familiar with Facebook, and not sure exactly what you're trying to do, but looks like at the end of this function user is redirected to Facebook.  If that's what you want to change, it's here -

// Redirect to Facebook
else
{
  $loginUrl = $helper->getLoginUrl(
  array('scope' => 'email')
  );
  header("Location: http://www.simplemachines.org");

The part I want to change is this

Code Select Expand


elseif ($user_info['is_guest'])
  {
  require_once($sourcedir . '/LogInOut.php');
  $modSettings['cookieTime'] = 3153600;
  DoLogin();
  }
In this part of the code user from Facebook is log in the forum using DoLogin() function.

[Sir Osis of Liver]

Changing $_SESSION['login_url'] should work.  DoLogin() returns to Login2(), which redirects to $_SESSION['login_url'] when login is successful.

Changing $_SESSION['login_url'] should work.  DoLogin() returns to Login2(), which redirects to $_SESSION['login_url'] when login is successful.

So each time when DoLogin() is call will go in Login2()?  Because I have change all the location where $_SESSION['login_url'] get new value and is not working... still going to forum index page. This is very strange.

[Sir Osis of Liver]

Have you tried setting $_SESSION['login_url'] in DoLogin()?

[Julian F]

Have you tried setting $_SESSION['login_url'] in DoLogin()?

No, where do I need to add that code in DoLogin()?

[Sir Osis of Liver]

DoLogin() is called from FacebookLogin(), it then goes to Login2(), which completes the login process and redirects the user to $_SESSION['login_url'].  All you're doing is assigning a value to $_SESSION['login_url'], you need to place it somewhere where it's not changed later in the login sequence.

[Julian F]

Hello,
I have search all the SMF project for $_SESSION['login_url'] and change it with custom link but seams when I login using social login is going to index page of the forum. If I use normal login with user and password all working fine.
Happy New Year!

Hello,
I have found the solution. It was very simple. Thank you.

[rockmanx4]

it is redirect 301 ? yes or no

[Sir Osis of Liver]

Redirect 301 is used in .htaccess to redirect from one url to another, and has nothing to do with this discussion.  Please open a new thread and provide details for what you're trying to do.
