i want to share my problem in my website

For the better understandng of my website, I want to tell all the details.

1. I have a database and i has a 2 tables 1 for the tbllogin which consist of Username and Department, and the second table is caltbl which i use for the calendar events.

2.When my website run the first webpage is the login form. If the Username and Department is correct she can browse the other webpages, like the calendar event.


3. In the calendar event you can see the calendar and when you click the date theirs a link "new event" appear and if theirs no existing event theres a text saying "No Events", when you click the link you can add events. I want that theirs a specific person that can only add events for the restriction of adding events. I want to happen that if the user is xxx and her department is yyy the link shoud appear and she can add events. i want that only to her the link should be appear..

here is the code:
