Disable the dropdown option when the database table has that option

[Ishan Shah]

Hello!

I have the table tbl_booking with field book_id,reg_id,preferred_date,timeslot,serviceprovider_id,and,services. I used select dropdown for the timeslot, to select the timeslot which will check on the tbl_booking and check that the particular serviceprovider_id and particular timeslot should select only 2 times on the particular date. Then the timeslot option should be disabled if the condition is true.
