This option allows to define a minimum number of characters for the
<input>
field and adds aminlength
attribute to the field. If at least one character is typed in and the number of characters is less thanmin
, 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, ifmin
is not reached.When using
min
in combination with , one has to make sure, themin
value is less than or equalmax
. 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 withmin
.Note
This option does not work for text fields, if RTE is enabled.
