Drupal 6: Load a CCK node $form object using drupal_retrieve_form
drupal_execute() is great for processing a form and drupal_get_form() is great for generating the html for a form, but what if you’d like to load the $form object to modify or embed it?
<?php
// include drupal's node include file
require("modules/node/node.pages.inc");
// create an empty $form_state array
$form_state = array();
// define the content type of the form you'd like to load
$nodeType = 'MYCCKNODETYPE';
// create a string of the $form_id
$form_id = $nodeType . '_node_form';
// create a basic $node array
$node = array('type' => $nodeType, 'uid' => $GLOBALS['user']->uid, 'name' => $GLOBALS['user']->uid);
// load the $form
$form = drupal_retrieve_form($form_id, $form_state, $node);
// prepare the $form
drupal_prepare_form($form_id, $form, $form_state);
// show the form structure, debug
echo "<PRE>";
print_r($form);
echo "</PRE>";
?>
