    Adding a new node and validating one field by comparing to another

    Trying to achieve the following:

    I have an Event doctype, with a Start Date and an End Date. If an End Date is chosen, I want to validate it by comparison with the Start Date, checking that an earlier date has not been chosen.

    I can only find regex validation options when setting up the Document Type, however.

    How would I go about doing this?

    you can only validate a single property and not another property's value, you could however:

    • -build your own datatype to include both start/end date on same property, or
    • -cancel out the save if start/end date values are not set correctly based on your specs.

    Both solutions would require some custom code, but it's quite straightforward to implement these.
