Allow members ability to display and edit specific info in MySQL table

[kemper]

I am hosting a sports website and am processing schedules for the particpating clubs to assign times and field assignments.  An example table is as follows:

What I want to do allow schedules from each club to see and edit their own specific schedules (eq. Club 1 would display only their own rows and be able to input times into "Time" column and specific field assignments into "Field" column).

I am not exactly sure where to start.  I have the complete schedule with 30 different clubs and 12 different ages in a MySQL database table already.  Site, membership, database already setup.  This has been in the works for years now.

Let's say "Club 1" Scheduler logs in. How can I write the script to display and allow editting to only "Club 2"?

Assistance is greatly appreciated.
