I want to build a custom edit form for a existing node. The edit form should not show all fields and should be populated with the existing field values. Furthermore I want to add a few custom submit buttons. I know I can pre populate the fields with #default_value, but there are quite a lot of fields I have to pre populate like that, so I wanted to pre populate them all at once.

I have made a form function with the following code:

$node = (array)node_load($nid);
$form_state = array();
$form_state['values'] = $node;
$form = node_form($form_state, $node);
drupal_prepare_form('node_form', $form, $form_state);

I have also defined a custom submit button:

   $form['submit_one'] = array(
       '#type' => 'submit',
       '#value' => t('Gereed'),
       '#weight' => 10,
       '#submit' => array('custom_form_submit_one'),  
   );

And a submit handler:

 function custom_form_submit_one($form_id, $form_values) {
   watchdog ("Hello","Hello");  
 }

When I press the submit button, the submit handler is not called.

When I disable the statement:

$node = (array)node_load($nid);

and I press the submit button, the submit handler is called. However, my form is not pre populated with the values.

Is it possible what I want to do? Can I use a custom form and pre populate the fields (without specifying #default_value for each field)?

Why must you have a separate form? I think a simpler approach would be to modify the existing form on a conditional basis via a form alter hook:

function hook_form_alter(&$form, &$form_state, $form_id) {
  // match our custom content type ('yourContentType_node_form') edit form, and ensure
  // we're editing a specific node
  if ($form_id == 'yourContentType_node_form' && arg(1) == '123') {
    // add new submit buttons
    $form['actions']['submit_one'] = array(
      '#type' => 'submit',
      '#value' => t('Gereed'),
      '#weight' => 10,
      '#submit' => array('custom_form_submit_one'),
    );
  }
}
  • I need to develop about ten custom forms, each with their own requirements, info fields and submit buttons. That's why I didn't want to use the form alter to change the edit form. Besides, the normal edit form should also still be available. That's why I thought developing a few custom forms would be the right thing to do. – Paul Mar 6 '13 at 23:12
  • Using the node id restriction in my example, you can expand on the code and create all of your different forms, without affecting the 'normal' version of this form. – Yuriy Babenko Mar 7 '13 at 0:41
