Available Validators (rules)

All validators are written as snake_case but it's up to the user's taste and could also be used as camelCase. So for example alpha_dash_spaces and alphaDashSpaces are both equivalent.

NOTE: on an input type="number", the + sign is an invalid character (browser restriction) even if you are using a signed validator. If you really wish to use the +, then change your input to a type="text".
