/** |

|
|
|
* Nested rule can be used for validation of nested structures. |
21
|
|
|
* |
22
|
|
|
* For example we have an inbound request with the following structure: |
23
|
|
|
* |
24
|
|
|
* ```php |
25
|
|
|
* $request = [ |
26
|
|
|
* 'author' => [ |
27
|
|
|
* 'name' => 'Dmitry', |
28
|
|
|
* 'age' => 18, |
29
|
|
|
* ], |
30
|
|
|
* ]; |
31
|
|
|
* ``` |
32
|
|
|
* |
33
|
|
|
* So to make validation with Nested rule we can configure it like this: |
34
|
|
|
* |
35
|
|
|
* ```php |
36
|
|
|
* $rule = new Nested([ |
37
|
|
|
* 'author.age' => [ |
38
|
|
|
* (new Number())->min(20), |
39
|
|
|
* ], |
40
|
|
|
* 'author.name' => [ |
41
|
|
|
* (new HasLength())->min(3), |
42
|
|
|
* ], |
43
|
|
|
* ]); |
44
|
|
|
* ``` |
