I have a php file in my Drupal 8 module.The name of my custom module is fb. Within the fb folder I have a php file fb.php .The content of that file is loaded as an iframe using the follwing code
public function buildForm(array $form, FormStateInterface $form_state) { $extpath = take_control_fb_ext_client_path(); $fbpath = take_control_client_path(drupal_get_path('module', 'fb') . '/fb.php?extpath=' . $extpath); global $base_url; $form['#attached']['take_Control_fb']['library'][] = 'fb/fb'; $form = array( 'take_control_fb_container' => [ '#type' => 'inline_template', '#template' => '', '#context' => [ 'url' => '/modules/fb/fb.php?extpath=/libraries/extjs/ext-3.4.1' ], ],
); return $form; } .I need to check drupal login is set or not in the fb.php file. I have used the following code to check that
$logged_in = \Drupal::currentUser()->isAuthenticated();
Ref link : https://docs.acquia.com/articles/there-drupal-function-check-if-user-logged
But it resulted the error 'PHP Fatal error: Class 'Drupal' not found'.
Please help me to figure out some solution to fix this.
