After Registration/Signin auto redirect url question

[mudmin]

Register - In version 4.3 and up, there is a file called
usersc/includes/scripts/during_user_creation.php

It's at the perfect spot for what you need.
Put this code at the bottom (editing your redirection page).

Code:

$user = new User();

Code:

$login = $user->loginEmail(Input::get('username'), trim(Input::get('password')), 'off');

Code:

if ($login) { Redirect::to('mypage.php');}

For facebook, you put your redirect after login on the admin dashboard under social logins.
For the others, you put it in usersc/includes/scripts/custom_login_script.php

I think that about covers it. Let me know if you have any issues.
