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​

LmcUser provides a View Helper (lmcUserIdentity) which you can use from any view script in your application.

<!-- Test if the User is connected -->
<?php if(!$this->lmcUserIdentity()): ?>
    <!-- display the login form -->
    <?php echo $this->lmcUserLoginWidget(['redirect'=>'application']); ?>
<?php else: ?>
    <!-- display the 'display name' of the user -->
    <?php echo $this->lmcUserIdentity()->getDisplayname(); ?>
<?php endif?>

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

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

Controller​

LmcUser provides a Controller Plugin (lmcUserAuthentication) 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->lmcUserAuthentication()->hasIdentity()) {
    //get the email of the user
    echo $this->lmcUserAuthentication()->getIdentity()->getEmail();
    //get the user_id of the user
    echo $this->lmcUserAuthentication()->getIdentity()->getId();
    //get the username of the user
    echo $this->lmcUserAuthentication()->getIdentity()->getUsername();
    //get the display name of the user
    echo $this->lmcUserAuthentication()->getIdentity()->getDisplayname();
}
?>

You can get the lmcuser_auth_service in a controller by doing:

$authService = $this->lmcUserIdentity()->getAuthService();

Service Manager​

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