Redirect to user course after login

Aim: When I login to Moodle, the system will redirect the user to his last accessed course.

Add the following code to \moodle\login\index.php (just before the "Go to my-moodle page instead of site homepage if defaulthomepage set to homepage_my" comment):

==================================================
//redirect user to his course (ignore if it is his first time login)
   if ( !empty( $user->lastcourseaccess ) ) {
      $mostRecent = 0;
      $mostRecentCourse = 0;
      foreach ( $user->lastcourseaccess as $k => $v ) {
         if ( $v > $mostRecent ) {
            $mostRecent = $v;
            $mostRecentCourse = $k;
         }
      }
      if ( $mostRecent != 0 ) {
         $urltogo = $CFG->wwwroot.'/course/view.php?id='.$mostRecentCourse;
      }
   }
}
