How to check if the user is logged in

Task

Check if the user is logged in (ie: user identity widget)

Solution

There are three ways.

View

ZfcUser provides a View Helper (zfcUserIdentity) which you can use from any view script in your application. Just add the following call to the location in your markup where you want the form to be rendered:

<?php echo $this->zfcUserIdentity(); ?>

You can also get user's fields (if the user is logged in), like email:

<?php echo $this->zfcUserIdentity()->getEmail(); ?>

The view helper may also return the Authentication Service :

<?php $authService = $this->zfcUserIdentity()->getAuthService(); ?>

Controller

ZfcUser provides a Controller Plugin (zfcUserAuthentication) which you can use from any controller in your application. You can check if the user is connected and get his data:

<?php
if ($this->zfcUserAuthentication()->hasIdentity()) {
    //get the email of the user
    echo $this->zfcUserAuthentication()->getIdentity()->getEmail();
    //get the user_id of the user
    echo $this->zfcUserAuthentication()->getIdentity()->getId();
    //get the username of the user
    echo $this->zfcUserAuthentication()->getIdentity()->getUsername();
    //get the display name of the user
    echo $this->zfcUserAuthentication()->getIdentity()->getDisplayname();
}
?>

Service Manager

$sm = $app->getServiceManager();
$auth = $sm->get('zfcuser_auth_service');
if ($auth->hasIdentity()) {
    echo $auth->getIdentity()->getEmail();
}
