Even with the number of validations available in RSForm!Pro now, there's still times where there's a need for some merged types, that perhaps would be helpful to create as default validation types.

For example, you can currently validate if a field is an email address (so that you get a correct email address) or you can validate if the email address being used is a unique submission (so that value can only be entered once) but you can't validate 'out of the box' to confirm that it's a unique value + is a valid email address in the one go.

You would need to follow this article: www.rsjoomla.com/support/documentation/v...validation-rule.html but then if you're keeping RSForm!Pro up to date over time, you're likely to risk overwriting your custom validations.

As a feature suggestion, can the following be looked at being added:
- Unique Value + Email Address = Validates if they've entered the value before, and checks it's a valid email address.
- Same as Other Field Value + Email Address = validates same email is entered twice, and that it's a valid email address.

Any other suggestions from readers?

An additional issue that would be good to have as a feature is to have separate validation messages for when a field is required vs when a field is invalid.

For example, a required email address that's unique for the form submission should actually get three validation options:
- if it's blank, it should ask for a value
- if it's not an email address, it should ask for it to be an email address
- if it's not unique, it should say that it's been entered already.
