Length

  • v::length(int $min, int $max)
  • v::length(int $min, null)
  • v::length(null, int $max)
  • v::length(int $min, int $max, boolean $inclusive = true)

Validates lengths. Most simple example:

v::stringType()->length(1, 5)->validate('abc'); // true

You can also validate only minimum length:

v::stringType()->length(5, null)->validate('abcdef'); // true

Only maximum length:

v::stringType()->length(null, 5)->validate('abc'); // true

The type as the first validator in a chain is a good practice, since length accepts many types:

v::arrayVal()->length(1, 5)->validate(['foo', 'bar']); // true

A third parameter may be passed to validate the passed values inclusive:

v::stringType()->length(1, 5, true)->validate('a'); // true

Message template for this validator includes {{minValue}} and {{maxValue}}.
