In admin page (CGridView) I have columns (for example):
Start_time End time
10:00:00 11:00:00
11:00:00 15:00:00
14:00:00 16:00:00
In above example, times may not overlap. What is the way to check it (I have no idea)? Times are in database, the best result would be select the times that overlap by ‘cssClassExpression’ in CGridView ( 15:00:00 and 14:00:00 ), but not necessairly.
