# Each
|
|
|
|
- `Each(Validatable $rule)`
|
|
|
|
Validates whether each value in the input is valid according to another rule.
|
|
|
|
```php
|
|
$releaseDates = [
|
|
'validation' => '2010-01-01',
|
|
'template' => '2011-01-01',
|
|
'relational' => '2011-02-05',
|
|
];
|
|
|
|
v::each(v::dateTime())->validate($releaseDates); // true
|
|
```
|
|
|
|
You can also validate array keys combining this rule with [Call](Call.md):
|
|
|
|
```php
|
|
v::call('array_keys', v::each(v::stringType()))->validate($releaseDates); // true
|
|
```
|
|
|
|
This rule will not validate values that are not iterable, to have a more detailed
|
|
error message, add [IterableType](IterableType.md) to your chain, for example.
|
|
|
|
If the input is empty this rule will consider the value as valid, you use
|
|
[NotEmpty](NotEmpty.md) if convenient:
|
|
|
|
```php
|
|
v::each(v::dateTime())->validate([]); // true
|
|
v::notEmpty()->each(v::dateTime())->validate([]); // false
|
|
```
