# OneOf
|
|
|
|
- `OneOf(Validatable ...$rule)`
|
|
|
|
Will validate if exactly one inner validator passes.
|
|
|
|
```php
|
|
v::oneOf(v::digit(), v::alpha())->validate('AB'); // true
|
|
v::oneOf(v::digit(), v::alpha())->validate('12'); // true
|
|
v::oneOf(v::digit(), v::alpha())->validate('AB12'); // false
|
|
v::oneOf(v::digit(), v::alpha())->validate('*'); // false
|
|
```
|
|
|
|
The chains above validate if the input is either a digit or an alphabetic
|
|
character, one or the other, but not neither nor both.
