Hi to all,
i am preparing an appointment booking web site for my uni project. However i am stuck on the last booking.php file. It enters the appointment start time and endtime however it shows Start Time: 11:00:00
Finish Time: 11:30:00
Duration: 0:30:00
Have been taken please select other times
and it inserts the information to the database however it does not overwrite it. Very interesting:))) Please take a look at the code and tell me what should i do cos i am not expert in php> Thanks - <?php

very poor technique to implement a web page. Its real hard to find error from page like this.
Why you expect information to be over written in database?
11:00:00
Finish Time: 11:30:00
Duration: 0:30:00
Have been taken please select other times
what is that mean?
And what you need? Please ask clearly.

Like johny10151981, I don't really understand your problem, but if I were to guess, I'd say you want to UPDATE data, not INSERT it.
Dear Sirs,
Thanks a lot for you replies. I am going crazy with this stuff because i am not php literate. My aim in here is to book an appointment. I have acquired all the selections to this page which has been made in the appointment process. What i really want is to book the selections made into the booking table and if same selections has been made and booked by the by client 1 previously, the system should ask the client2 to make different selection, however if the booking table is empty than it should insert all the selections to the booking table.
I know it sounds bit confusing but its straight forward, Example
Client 1: Books an appointment on 15th of september, at 11:00 with staff name alex. Once this is booked another person say client 2 should not make appointment with staff name alex on 15th of september, at 11:00 oclock.
Cheers. Mem
In that case think this way,
say staff Alex's id is $id. $id has five appointment. -
appointment_id time duration
-
01 9:30 30
-
04 10:15 30
-
08 11:00 30
-
10 12:30 30
-
11 13:00 30
-
forget the date for a while
look at the table status
after 01 appointment he has a break from 10:00 to 10:15 which mean 15 minutes
after 04 appointment he has a break from 10:45 to 11:00 which mean 15 minutes
after 08 appointment he has a break from 11:30 to 12:30 which mean 60 minutes
Now if you sort the table in time order not appointment_id order you can easily find out the empty duration to check whether the guest appointment can be fit or not
As well as you can find out the busy duration to find out whether you fit the appointment or not.
say a guest want an appointment at 12:15. He cant get an appointment cause his start time (12:00<12:15 and 12:30>12:15)==true which mean busy schedule.
again he cant get a schedule at 10:00 cause, his schedule end time 10:30 which would be in busy schedule too.
Rest figure out yourself cause its your school project.
