Create CCK Node Form in a Collapsible Fieldset

NOTE: this page has been replaced.

I wanted to embed a form in the page of a custom module to create a CCK node type. I thought it would be neat to enclose the form in a collapsible fieldset...

<?php
function MODULENAME_SOMEFUNCTION() {
  $page_contents = "";
  //...code...
  $page_contents .= drupal_get_form('_MODULENAME_cck_form', 'MY_CCK_NODE_TYPE');
  //...code...
  return $page_contents;
}

function _MODULENAME_cck_form($nodeType) {
  $form = array();
   
  // get a list of node types
  $nodeTypes = node_get_types();
   
  // create empty node
  $node = array(
    'type'    => $nodeType,
    'uid'      => $GLOBALS['user']->uid,
    'name'    => $GLOBALS['user']->name,
  );
   
  // create the cck form fields
  $form = content_form($node);

  // get a list of node forms
  $nodeForms = node_forms();
   
  // get the callback for this node type
  $nodeFormCallback = $nodeForms[$nodeType.'_node_form']['callback'];
   
  // get the node form fields
  $form = array_merge($form, node_form($node));
   
  // add fieldset
  $fieldset = array();
  $fieldset[$nodeType] = array(
    '#type' => 'fieldset',
    '#title' => 'Add ' . $nodeTypes[$nodeType]->name,
    '#collapsible' => TRUE,
    '#collapsed' => TRUE,
  );
   
  // add form to fieldset
  foreach ($form as $k => $v) {
    $fieldset[$nodeType][$k] = $v;
  }
   
  return $fieldset;
}
?>
