Registration Hooks don't appear to be working

Question

I am trying to hook in to automatically sign-in the user after registration. (using a GravityForms registration form).

None of the hooks seem to be working. I've tried: gform_user_registered, user_register, a filtered 'update_user_metadata'....

Why would this not kill the script after a registration happens?

add_action("user_register", "my_auto_login");
function my_auto_login($user_id) {
    die('x');
}

Login after registration seems like it should not be that complicated.

Answer 1

Use the Gravity forms gform_user_registered hook. It fires after the registration and will return the $user_id.

function my_auto_login( $user_id ) {
wp_set_auth_cookie( $user_id, false, is_ssl() );
wp_redirect( admin_url( 'profile.php' ) );
exit;
}

add_action( 'gform_user_registered', 'my_auto_login' );
