This is a continuation of this issue, where I couldn’t get the ajax to fire on an entity reference field in a node edit form. With the following code, I’m able to get the ajax to fire.
/** * Implementation of hook_form_FORM_ID_alter() */ function mymodule_form_blog_node_form_alter(&$form, &$form_state, $form_id) { $form['field_video_reference']['#ajax'] = array( 'callback' => 'mymodule_video_ajax_callback', 'wrapper' => 'my-path-div', ); $form['my_path'] = array( '#markup' => t('My path'), '#prefix' => '<div id="my-path-div">', '#suffix' => '</div>', '#weight' => 6, ); if (!empty($form_state['values']['field_video_reference']['und'][0]['target_id'])) { $form['my_path']['#markup'] = 'Token path: http://www.mysite.org/node/' . $form_state['node']->field_video_reference['und'][0]['target_id']; } } function mymodule_video_ajax_callback($form, $form_state) { return $form['my_path']; } The problem is that the value from field_video_reference isn’t being passed to the if statement in the form builder or my callback, so the value from that field isn’t displayed in the my_path field when the value is first selected on the node create form (it works fine if the node has already been saved and there is a value in field_video_reference when I edit the node). I’m following examples from the “Drupal 7 Module Development” book as well as from the Examples module, so I can’t see what I’m missing.
Thanks.
