Version compatibility with Drupal 5.x

Hi

Thanks for the module. I've modified it sightly so it is compatible with 5.x

Two changes:

Comment submitagain_form_node_type_form_alter function, as it has no effect in 5.x.

Modify submitagain_form_alter like this:

function submitagain_form_alter($form_id, &$form) {
  if (strpos($form_id, '_node_form') && !isset($form['nid']['#value'])) {
    if (variable_get('submitagain_'. $form['type']['#value'], false)) {
      $form['submit_again'] = array(
        '#type' => 'submit',
        '#value' => t('Save and create another'),
        '#weight' => 41,
        '#submit' => array('node_form_submit')
      );
      $form['#theme'] = 'submitagain_node_form';
    }
  }
  
  if (isset($form['identity']['type'])) {
    $form['submission']['submitagain'] = array (
      '#type' => 'checkbox',
      '#title' => t('Submit Again?'),
      '#default_value' => variable_get('submitagain_' . $form['#node_type']->type, false),
      '#description' => t('Enable this checkbox if you want to provide a "Save and create another" button for your users.')
    );
  }
}

Hope it helps!!!
