/** |
|
23
|
|
|
* Can be used for validation of nested structures. |
|
24
|
|
|
* |
|
25
|
|
|
* For example, we have an inbound request with the following structure: |
|
26
|
|
|
* |
|
27
|
|
|
* ```php |
|
28
|
|
|
* $request = [ |
|
29
|
|
|
* 'author' => [ |
|
30
|
|
|
* 'name' => 'Dmitry', |
|
31
|
|
|
* 'age' => 18, |
|
32
|
|
|
* ], |
|
33
|
|
|
* ]; |
|
34
|
|
|
* ``` |
|
35
|
|
|
* |
|
36
|
|
|
* So to make validation we can configure it like this: |
|
37
|
|
|
* |
|
38
|
|
|
* ```php |
|
39
|
|
|
* $rule = new Nested([ |
|
40
|
|
|
* 'author' => new Nested([ |
|
41
|
|
|
* 'name' => [new HasLength(min: 3)], |
|
42
|
|
|
* 'age' => [new Number(min: 18)], |
|
43
|
|
|
* )]; |
|
44
|
|
|
* ]); |
|
45
|
|
|
* ``` |
