Options

limit

type: integer [default option]

This required option is the "min" value. Validation will fail if the length of the give string is less than this number.

message

type: string default: This value is too short. It should have {{ limit }} characters or more

The message that will be shown if the underlying string has a length that is shorter than the limit option.

charset

type: charset default: UTF-8

If the PHP extension "mbstring" is installed, then the PHP function mb_strlen will be used to calculate the length of the string. The value of the charset option is passed as the second argument to that function.
