function ajax_example_simplest($form, &$form_state) {
  $form = array();
  $form['changethis'] = array(

    '#ajax' => array(
      // #ajax has two required keys: callback and wrapper.
      // 'callback' is a function that will be called when this element changes.
      'callback' => 'ajax_example_simplest_callback',
      // 'wrapper' is the HTML id of the page element that will be replaced.
      'wrapper' => 'replace_textfield_div',
      // There are also several optional keys - see ajax_example_autocheckboxes
      // below for details on 'method', 'effect' and 'speed' and
      // ajax_example_dependent_dropdown for 'event'.
    ),
  );
 
  // This entire form element will be replaced whenever 'changethis' is updated.
  $form['replace_textfield'] = array(
    '#type' => 'textfield',
    '#title' => t("Why"),
    // The prefix/suffix provide the div that we're replacing, named by
    // #ajax['wrapper'] above.
    '#prefix' => '<div id="replace_textfield_div">',
    '#suffix' => '</div>',
  );
 
  // An AJAX request calls the form builder function for every change.
  // We can change how we build the form based on $form_state.
  if (!empty($form_state['values']['changethis'])) {
    $form['replace_textfield']['#description'] = t("Say why you chose '@value'", array('@value' => $form_state['values']['changethis']));
  }
  return $form;
}
 
function ajax_example_simplest_callback($form, $form_state) {
  // The form has already been submitted and updated. We can return the replaced
  // item as it is.
  return $form['replace_textfield'];
}

J'essaie de mettre le texte qui apparait dans le div dans l'emplacement du champ texte, sans succès.
(quand je change une valeur dans le menu, un texte apparait sous le champs texte, et j'aimerais qu'il apparaisse dans le champ texte), je ne sais pas si c'est clair.

N'avez-vous une idée, ou me donner une direction?

Merci.

Bonjour,

Il te suffi de remplacer le contenu du champs texte par celui de la div... non ?

Code:

$form[champstexte] = $form[textediv]

Enfin du coup je ne suis pas sur du tout d'avoir bien saisis ton énoncé.
Si je peux te donner un conseil, installe le module devel. C'est outil de debug de Drupal le mieux côté ;)
Avec lui d'installer tu auras accès à la fonction dpm() (C'est un print_r un peu améliorer)

Exemple rapide en reprenant la fonction
