I have a calendar script that displays up to 6 appointments per morning and per afternoon on any given day. It counts how many are remaining and if all 6 are taken then displays FULL. What I would also like to do is to be able to block out a morning, afternoon, whole day or even whole week (for a holiday for example) and mark them as FULL without having to add 6/12/84 individual rows to the db.
I have tried adding a column called 'block' and setting it's value to 1 for a given day, 0 as default, but I can't get both queries to run at the same time. It then doesn't display the days that still have 6 appointments (i.e. don't have any rows in the db therefore don't have a block value of 0 OR 1). I've tried every which way of nesting 2 while loops and I've tried IF EXISTS in the sql, exists/isset in the PHP but just can't get it to work. Can anyone please help?
