Provides administrative UI for workflow. Why it's own module? Lower code footprint and better performance. Additional creadit to gcassie ( http://drupal.org/user/80260 ) for the initial push to split UI out of core workflow. We're moving…

Code

function workflow_admin_ui_add_form_validate($form, &$form_state) {
  $workflow_name = $form_state['values']['wf_name'];
  $workflows = array_flip(workflow_get_all());

  // Make sure a nonblank workflow name is provided.
  if ($workflow_name == '') {
    form_set_error('wf_name', t('Please provide a nonblank name for the new workflow.'));
  }

  // Make sure workflow name is not a duplicate.
  if (array_key_exists($workflow_name, $workflows)) {
    form_set_error('wf_name', t('A workflow with the name %name already exists. Please enter another name for your new workflow.', array(
      '%name' => $workflow_name,
    )));
  }
