PHP EfrontUser::isStudentRole方法代码示例

 /**
  * Add users to course
  *
  * This function is used to register one or more users to the current course. A single login
  * or an array of logins may be specified
  * <br/>Example:
  * <code>
  * $course -> addUsers('joe', 'professor');         //Add the user with login 'joe' as a professor to this course
  * $users = array('joe', 'mary', 'mike');
  * $types = array('student', 'student', 'professor');
  * $course -> addUsers($users, $types);             //Add the users in the array $users with roles $types
  * </code>
  *
  * @param mixed $login The user login name
  * @param mixed $role The user role for this course, defaults to 'student'
  * @param boolean $confirmed If false, then the registration is set to 'pending' mode and the administration must confirm it
  * @since 3.5.0
  * @access public
  * @todo deprecated
