New in version 12.0

min (type => text)






This option allows to define a minimum number of characters for the <input> field and adds a minlength attribute to the field. If at least one character is typed in and the number of characters is less than min, the FormEngine marks the field as invalid, preventing the user to save the element. DataHandler will also take care for server-side validation and reset the value to an empty string, if min is not reached.

When using min in combination with max, one has to make sure, the min value is less than or equal max. Otherwise the option is ignored.

Empty fields are not validated. If one needs to have non-empty values, it is recommended to use required => true in combination with min.
