php - Call to undefined method AuthenticationControllerComponentAuthenticationComponent::user()

one text

Solution:

You were probably looking at the wrong docs, specifically at the docs of the deprecated Auth component that belongs to the CakePHP core.

You should refer to the docs of the new authentication plugin, which is where its Authentication component usage is documented. The method for accessing the user via the Authentication component is called getIdentity:

$identity = $this->Authentication->getIdentity();

Furthermore, for your specific use case there is also a view helper that provides a method for checking whether the user is logged in. In your AppView::initialize() method (src/View/AppView.php) load the helper:

$this->loadHelper('Authentication.Identity');

Then you can use its isLoggedIn method in your view templates, no further code needed in your controller:

<?php if($this->Identity->isLoggedIn()): ?>
    ...
<?php endif; ?>
