This is the documentation for ConfiForms Server/Data Center app


This tutorial shows how to design a form with custom validation rule to ensure date time intervals registered with this form dont overlap

Here is what we have in our form - just 2 fields

  • one of type text to hold a title for our event
  • date/time interval field to hold an event's interval

We want to ensure the events dont overlap, so we will add a custom validation rule to our form

With action "Validation rule" agains dataset

And condition to check that intervals dont overlap like this

(eventDT.startDate:<=[entry.eventDT.endDate] AND eventDT.endDate:>=[entry.eventDT.startDate] AND !id:[entry.id])


We will show the form data in a CalendarView like this:

This is done by simply configuring CalendarView to use our form and have a calendar built using "eventDT" field

When you try to register an event with dates overlapping the ones we have already registered an error message is shown (the one we have defined in our custom validation rule)
