# AllOf - `v::allOf(v $v1, v $v2, v $v3...)` Will validate if all inner validators validates. ```php v::allOf( v::intVal(), v::positive() )->validate(15); // true ``` This is similar to the chain (which is an allOf already), but its syntax allows you to set custom names for every node: ```php v::allOf( v::intVal()->setName('Account Number'), v::positive()->setName('Higher Than Zero') )->setName('Positive integer') ->validate(15); // true ``` *** See also: * [NoneOf](NoneOf.md) * [OneOf](OneOf.md) * [When](When.md)
