# When
|
||
|
|
|
||
|
|
- `v::when(v $if, v $then, v $else)`
|
||
|
|
- `v::when(v $if, v $then)`
|
||
|
|
|
||
|
|
A ternary validator that accepts three parameters.
|
||
|
|
|
||
|
|
When the `$if` validates, returns validation for `$then`.
|
||
|
|
When the `$if` doesn't validate, returns validation for `$else`, if defined.
|
||
|
|
|
||
|
|
```php
|
||
|
|
v::when(v::intVal(), v::positive(), v::notEmpty())->validate($input);
|
||
|
|
```
|
||
|
|
|
||
|
|
In the sample above, if `$input` is an integer, then it must be positive.
|
||
|
|
If `$input` is not an integer, then it must not me empty.
|
||
|
|
When `$else` is not defined use [AlwaysInvalid](AlwaysInvalid.md)
