Instructions below
To extend an Activity properties do:
public function onActivityPubValidateActivityStreamsTwoData(string $type_name, array &$validators): bool {
if ($type_name === '{Type}') {
$validators['attribute'] = myValidator::class;
}
return Event::next;
}
The Validator should be of the form:
use ActivityPhp\Type;
use ActivityPhp\Type\Util;
use Plugin\ActivityPub\Util\ModelValidator;
class myValidator extends ModelValidator
{
/**
* Validate Attribute's value
*
* @param mixed $value from JSON's attribute
* @param mixed $container A {Type}
* @return bool
* @throws Exception
*/
public function validate($value, $container): bool
{
// Validate that container is a {Type}
Util::subclassOf($container, Type\Extended\Object\{Type}::class, true);
return {Validation Result};
To act on received activities do:
public function onActivityPubNew{Type}(&$obj): bool {
To add information to Activities being federated by ActivityPub do:
public function ActivityPubAddActivityStreamsTwoData(string $type_name, &$type): bool {
To implement an ActivityStreams 2.0 representation do:
public function onActivityPubActivityStreamsTwoResponse(string $route, arrray $vars, ?TypeResponse &$response = null): bool {
if ($route === '{Object route}') {
$response = ModelResponse::handle($vars[{Object}]);
return Event::stop;
}
return Event::next;
