/** |

|
|
* Can be used for early stopping the validation process of the value when the validation on the stage was failed. |
|
14
|
|
|
* |
|
15
|
|
|
* For example, we have several rules, but we want not to process the rest rules when fail was ocurred: |
|
16
|
|
|
* |
|
17
|
|
|
* ```php |
|
18
|
|
|
* $request = [ |
|
19
|
|
|
* 'username' => 'yiisoft', |
|
20
|
|
|
* ]; |
|
21
|
|
|
* ``` |
|
22
|
|
|
* |
|
23
|
|
|
* So to make validation we can configure it like this: |
|
24
|
|
|
* |
|
25
|
|
|
* ```php |
|
26
|
|
|
* $rule = new StopOnError([ |
|
27
|
|
|
* new HasLength(min: 3), |
|
28
|
|
|
* // Heavy operation. It would be great not to call it if the previous rule was failed. |
|
29
|
|
|
* new ExistsInDatabase(), |
|
30
|
|
|
* ]); |
|
31
|
|
|
* ``` |
