I have a web service on third party system that return property of doctor and I have a content type named "doctor". I want when user go to a url like doctor/23 drupal create a node of type doctor based on url arg and show this node to user. for that and with @zaporylie help i create a custom controller like bellow

create a Routing:

  path: 'doctor/{doctor_id}'
    _controller: '\Drupal\showdoctor\Controller\LoadDoctorController::load'
    _title: 'load'
    _permission: 'access content'

and my controller like this:

    class LoadDoctorController extends ControllerBase
    public function load($doctor_id)
        $result = RestCurl::post("http://myrest_server.com", [
            'filter' => ['doctor.id' => $doctor_id],

        $fullname = $result['data']->message->data[0]->firstName;
        $fullname = $fullname . ' ' . $result['data']->message->data[0]->lastName;
        // Fetch doctor node with EFQ
        $query = \Drupal::entityQuery('node');
        $query->condition('type', 'doctor');
        $query->condition('field_doctor_id', $doctor_id);
        $nids = $query->execute();
        if (!$nids) {
            $node = Node::create([
                'type' => 'doctor',
                'title' => $fullname,
                'uid' => 1,
            $node->set('field_doctor_id', $doctor_id);
            $element = array(
                '#markup' => $node,
            return $element;
        } else {
            $element = array(
                '#markup' => $node,
            return $element;


Now for example when in go to doctor/23 page i see a page with load title. and if i refresh this page i see doctor page correctly. i think my problem is return value.

You should create a custom Controller rather than hook on page load. This way you won't have an overhead on every page load. In the Controller (accessible under movie/{movie_id} route) try to load movie by movie_id (entityQuery), and if it does not exists simply create one based on data from 3rd party service and display in a display mode of your choice.

  • Thanks @zaporylie. in Controller how return value for show created movie?
