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".

• accepted The field under validation must be yes, on, 1, or true. Useful for validating "Terms of Service" acceptance.

• alpha Only alpha characters (including latin) are present (a-z, A-Z)

• alpha_spaces Only alpha characters (including latin) and spaces are present (a-z, A-Z)

• alpha_num Only alpha-numeric characters (including latin) are present (a-z, A-Z, 0-9)

• alpha_num_spaces Only alpha-numeric characters (with latin & spaces) are present (a-z, A-Z, 0-9)

• alpha_dash Only alpha-numeric characters + dashes, underscores are present (a-z, A-Z, 0-9, _-)

• alpha_dash_spaces Alpha-numeric chars + dashes, underscores and spaces (a-z, A-Z, 0-9, _-)
