I have a content type leg and this hook_menu :

$items['leg'] = array(
    'title' => t('Choose Leg'),
    'page callback' => 'drupal_get_form',
    'access arguments' => array('create leg content'),
    'page arguments' => array('mymodule_leg_select_form'),
    'type' => MENU_NORMAL_ITEM,
    'weight' => 0,

$items['leg/select'] = array(
    'title' => t('Choose an existing leg'),
    'page callback' => 'drupal_get_form',
    'access arguments' => array('create leg content'),      
    'page arguments' => array('mymodule_leg_select_form'),
    'weight' => 1,

$items['leg/add'] = array(
    'title' => t('Create a new leg'),
    'page callback' => 'drupal_get_form',
    'access arguments' => array('create leg content'),      
    'page arguments' => array('leg_node_form'),
    'type' => MENU_LOCAL_TASK,
    'weight' => 2,
return $items;

Here is the code snippet from mymodule_leg_select_form() which is called as MENU DEFAULT LOCAL TASK :

$form = array();    
$result = db_query('SELECT nid, title FROM {node} WHERE type = :type AND status = :status ORDER BY title', array(':type'=>'leg', ':status'=>1));
$options = array();
foreach($result as $row){
    $options[$row->nid] = $row->title;
$form['leg'] = array(
    '#type' => 'select',
    '#title' => t('Leg'),
    '#options' => $options,
    '#required' => TRUE,

$form['submit'] = array(
    '#type' => 'submit', 
    '#value' => t('Ok'),
    '#weight' => 1,

return $form;

The node form is not rendered correctly as you can see in the screen shot. I have two fields - field_from and field_to. They are not rendered in the form. The menu path "leg/select" which is default local task did work and correctly rendered my custom form.

The problem only is to integrate node add form in the second tab. How can I fix this error ?

  • Did you clear the cache? This look like old stuff is still hanging around.

  • Post the leg_node_form function. Are all of these in the same .module file?

  • I think there is no leg_node_form function. It is just a form id to the drupal node form infrastructure in the form of {contenttype}_node_form.

The problem is not your hook_menu implementation, but your function leg_node_form. That function probably calles node_form, which is in file modules/node/node.pages.inc you have to include that file manually using module_load_include.

  • After I added this : function mymodule_init(){ module_load_include('inc', 'node', 'node.pages'); }. I got this error : Fatal error: Cannot access empty property in C:\xampp\htdocs\mysite\modules\field\field.attach.inc on line 197

  • I see this issue at drupal.org/node/947748, but they are saying about media module and drupal beta verson. I have no media module and my drupal is 7.7.

  • A better place to include node.pages.inc would be the function that calls node_form (I suspect this is mymodule_leg_select_form). Also, if the error is in function mymodule_leg_select_form, show us this function.

  • I updated my original post with the code for mymodule_leg_select_form, but it is called by menu default local task. I got the error only when I navigate to the second tab. I tried to add 'file' and 'file path' to node.pages.inc in the menu registration "leg/add". But still see the error : Fatal error: Cannot access empty property in path\to\site\modules\field\field.attach.inc on line 197. I have two fields for the content type leg - field_from and field_to and hided title and body field.

  • Sorry, I got confused. I suspect the error is in leg_node_form.
