Seeing that my modules are irretrievably borked, I want to generate a form from a php document in the nodes.

Only problem (thus far!) is that my form does not render.

My script is as follows:

global $user;
$form['#attributes'] = array('enctype' => "multipart/form-data");
$form['title'] = array(
  '#type' => 'textfield', 
  '#title' => t('Article Name'),
  '#size' => 60,
  '#maxlength' => 64, 
  '#required' => TRUE
);

$form['body'] = array(
  '#type' => 'textarea', 
  '#title' => t('Description'), 
  '#default_value' => $node->body
);

$form['document_upload'] = array(
  '#type' => 'file', 
  '#title' => t('Upload The Article'), 
  '#size' => 40,
);

$form['submit'] = array(
  '#type' => 'submit',
  '#value' => t('Save'),
);
$form['#validate'] = array('kwbse_node_form_validate');

function kwbse_node_form_validate($form, &$form_state) {
  if (isset($form['document_upload'])) {
    $validators = array(
      'file_validate_extensions' => array('pdf')
    );
    $file = file_save_upload('document_upload', $validators);
    if (!$file)
      form_set_error('upload', 'You must select a valid file to upload.');
    else {
      $form_state['values']['taxonomy[2]'] = 1;
			$node = node_submit($form_state['values']);
			$node->type = 'knoledgebase';
			$node->uid = $user->uid;
			node_save($node);
    }
  }
}

Clearly I need to call a function to render the form on the page...

You need to wrap the $form object code into a function that returns the object. Then, you call call to render the form.

Ah! Thanks Steven,

The clue was the final comment on the link you provided.

If the form is defined in a function called spaceman_spiff_form(form_state), then the function would appear to be called by the command echo drupal_get_form('spaceman_spiff_form');

Not the way most languages work, but nevermind!

I'll test it out and report back.

echo drupal_get_form('spaceman_spiff_form');//<----- The important line right here

Works fine.
