I need to create a timetable in php.
Example: we need to create timetable for two classes as LKG-A and LKG-B. There are 5 periods and 5 teachers for both the classes.
Suppose if we choose a teacher for first period in LKG-A that teacher should not be visible for LKG-B at the same time. we should create a
drop down box for each column to see the teachers list. Please help me to do this.
