IPS 4.4 External Login

Cyber1 · May 25, 2019

Hi guys, anyone know how to do external login on IPS 4.4 version?

Code below is working on IPS4.2 btw .. question is how to do it on newest ips version.

require_once(dirname(__FILE__).'/../forums/init.php');
$IPSLogin = new \IPS\Login\Internal;
$IPSLogin->init();

try {
         $member = $IPSLogin->authenticate(array('auth' => $_POST['username'], 'password' => $_POST['password']));
         if ($member) {
            $expire = new \IPS\DateTime;
            $expire->add( new \DateInterval( 'P7D' ) );
            \IPS\Request::i()->setCookie( 'member_id', $member->member_id, $expire );
            \IPS\Request::i()->setCookie( 'pass_hash', $member->member_login_key, $expire );
            \IPS\Request::i()->setCookie( 'hasJS', true, $expire );
            print '<html><head><meta http-equiv="refresh" content="0;URL=\''.$prev_url.'\'"></head></html>';
         }
      } catch (Exception $e) {
         blahblah
      }

any sample script on how to make external login with this function?

any other suggestion?

If you want to use the external login with a website that supports API, ex VK/WordPress. Better use oAuth.

Alternative,

Or try restApi.
