# 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:
|
|
|
|
```php
|
|
v::stringType()->length(1, 5)->validate('abc'); // true
|
|
```
|
|
|
|
You can also validate only minimum length:
|
|
|
|
```php
|
|
v::stringType()->length(5, null)->validate('abcdef'); // true
|
|
```
|
|
|
|
Only maximum length:
|
|
|
|
```php
|
|
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:
|
|
|
|
```php
|
|
v::arrayVal()->length(1, 5)->validate(['foo', 'bar']); // true
|
|
```
|
|
|
|
A third parameter may be passed to validate the passed values inclusive:
|
|
|
|
```php
|
|
v::stringType()->length(1, 5, true)->validate('a'); // true
|
|
```
|
|
|
|
Message template for this validator includes `{{minValue}}` and `{{maxValue}}`.
