Hi,
Another feature request :)
What would be a nice addition to the Forms module. That you can set some kind of validation on fields, for instance to check if an e-mail address field really contains an e-mail address.
To give you a pointer in the right direction, maybe you can think of the following.
Per field allow to have a regular expression that must be matched in order for the field to be valid.
And per field allow to have a custom message, so that I can tell the user something like "Please enter an e-mail address".
Kind Regards,
Emil
