Attribute

  • v::attribute(string $name)
  • v::attribute(string $name, v $validator)
  • v::attribute(string $name, v $validator, boolean $mandatory = true)

Validates an object attribute.

$obj = new stdClass;
$obj->foo = 'bar';

v::attribute('foo')->validate($obj); //true

You can also validate the attribute itself:

v::attribute('foo', v::equals('bar'))->validate($obj); //true

Third parameter makes the attribute presence optional:

v::attribute('lorem', v::string(), false)->validate($obj); // true

The name of this validator is automatically set to the attribute name.
