Some of my scheduled task needs to run as the user who triggered them (not anonymous neither admin); so I thought of writing two actions:

- One to impersonate a user, which will receive uid as an argument.

- Another to undo the impersonate.

All the called actions should be between them.

Anybody see any fault in this idea or the actions code?

Thanks.

function wu_action_impersonate($uid) {

  global $user;

  if (!array_key_exists('wu_action_impersonate', $_SESSION)) {

    $_SESSION['wu_action_impersonate'] = array();

  }

  array_push($_SESSION['wu_action_impersonate'], $user);

  session_save_session(FALSE);

  $user = user_load($uid);

  user_load($uid);

}

function wu_action_unimpersonate() {

  global $user;

  if (array_key_exists('wu_action_impersonate', $_SESSION)) {

    if (!empty($_SESSION['wu_action_impersonate'])) {

      $user = array_pop($_SESSION['wu_action_impersonate']);

    }

    if (empty($_SESSION['wu_action_impersonate'])) {

      unset($_SESSION['wu_action_impersonate']);

    }

  }

  session_save_session(TRUE);

}
