Inhalt eines Cookies in Webform anzeigen

Ich würde zu diesem Zwecke ein kleines Modul schreiben, das hook_form_alter implementiert, darin das Cookie ausliest und das Feld vorbesetzt.

Hallo , ich habe den obigen Rat befolgt und mein erstes Modul geschrieben.

In webform_cookies.module ist folgende Funktion.

Das funktioniert für jeden Node auf der Seite, d.h. das Modul wird erkannt.

Jetzt ist mir aber nicht klar, wie ich auf den Formularseiten mit dem Component "name_des_kindes" den Cookie-Wert als default erscheinen lasse. Mir schwebt Folgendes vor:

function webform_cookies_form_alter(&$form, &$form_state, $form_id){
if ( $_COOKIE['Drupal_visitor_name']&& $form['name_des_kindes']){
$form['name_des_kindes']['value'] = $_COOKIE['Drupal_visitor_name'];
}
}

Das führt aber für jeden node zu folgender Fehlermeldung.

Notice: Undefined index: name_des_kindes in webform_cookies_form_alter() (line 7 of C:\xampp\htdocs\mysites\drupal\sites\all\modules\webform_cookies\webform_cookies.module).

Wie spreche ich die Felder eines Formulars in einem hook richtig an?

Vielen Dank für Eure Mühe
Carla

du musst dir zunächst einmal die Struktur des Form- Arrays ansehen. Wenn du keine IDE mit Debugger benutzt, am Besten das Devel Modul installieren. Dann kannst du dir mit dpm($form); innerhalb des form alter hooks die Formular Array- Struktur genau ausgeben lassen. Da wirst du dann so etwas wie

setzen können.

Hallo, leider funktioniert das immer noch nicht.
dpm($webform) gibt folgende Fehlermeldung:
Notice: Undefined variable: webform in webform_cookies_form_alter() (line 13 of C:\xampp\htdocs\mysites\drupal\sites\all\modules\webform_cookies\webform_cookies.module)

Devel zeigt diese Struktur an:

Wie muß ich da ['#default_value'] einbauen, damit der Cookie im Feld"Name des Kindes" erscheint?
