Need Help with a scheduler

[sidarian]

I am trying to code a program in PHP that would allow a user to schedule a stay at this place, it would save that to a database. If a particular day has 5 people booking it, it is no longer able to be scheduled. I can't get the scheduler page to check how many people have booked or my calendar to display a day in red if it is booked.

can you give us an example of what the scheduler page looks like... this should be a simple check... run a query, see if there are 5 results, if so, deny adding of more
