Is it possible to combine validators?

[JorindeReijnierse]

Is it possible to either have two validators on one input or use an existing validator within a custom validator? For a form input for a birthdate I have to check if the date that's entered is a real date (birthdate validator) but also if the age is between 18 & 65 (custom validator).

You can apply several validators on one input, separating them with space or comma.

<input type="text" data-validation="alphanumeric length" data-validation-length="5-20" />

So in your case it would be something like data-validation="birthdate mycustomvalidator"

btw, The age-range should be part of the birthdate validator, I'll add that as a feature request.

As of version 2.3.64 it's possible to constrain allowed age when using the validator birthdate (provided by the date module)

<input data-validation="birthdate"> // allows any age between 0-124 years
<input data-validation="birthdate" data-validation-age-range="18-65">
