			0 ignored issues – show Bug introduced 2017-04-24 07:50 UTC by Report Bug Copy Issue Report It seems like you code against a concrete implementation and not the interface `Sylius\Component\Resourc...el\TranslationInterface` as the method `getName()` does only exist in the following implementations of said interface: `Sylius\Component\Attribu...el\AttributeTranslation`, `Sylius\Component\Core\Model\ProductTranslation`, `Sylius\Component\Payment...aymentMethodTranslation`, `Sylius\Component\Product...ociationTypeTranslation`, `Sylius\Component\Product...uctAttributeTranslation`, `Sylius\Component\Product...roductOptionTranslation`, `Sylius\Component\Product\Model\ProductTranslation`, `Sylius\Component\Product...oductVariantTranslation`, `Sylius\Component\Shippin...ippingMethodTranslation`, `Sylius\Component\Taxonomy\Model\TaxonTranslation`. Let’s take a look at an example: interface User { /** @return string / public function getPassword(); } class MyUser implements User { public function getPassword() { // return something } public function getDisplayName() { // return some name. } } class AuthSystem { public function authenticate(User $user) { $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName())); // do something. } } In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes Change the type-hint for the parameter: class AuthSystem { public function authenticate(MyUser $user) { / ... / } } Add an additional type-check: class AuthSystem { public function authenticate(User $user) { if ($user instanceof MyUser) { $this->logger->info(/* ... /); } // or alternatively if ( ! $user instanceof MyUser) { throw new \LogicException( '$user must be an instance of MyUser, ' .'other instances are not supported.' ); } } } Note:* PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
