This might be useful. See the Utilizing CodeIgniter Resources within Your Library section.

Fatal error: Call to a member function red_alert() on a non-object in /home/corpusad.com/httpdocs/faceapp/application/modules/lansinoh_app/controllers/lansinoh_app.php on line 66

this is the error that i recieved.

Not sure, the code you posted doesn't seem to be related to your problem. According to the error message, your error is in the controller, lansinoh_app, not the Alerts library.

Are you using a 3rd party extension? "Modules" is not part of CI, and could be where the problem is coming in.
