Code

function pathauto_form_alter($formid, &$form) {

  // Only do this for node forms

    // See if there is a pathauto pattern or default applicable
    $pattern = trim(variable_get('pathauto_node_' . $form['type']['#value'] . '_pattern', FALSE));
    if (!$pattern) {
      $pattern = trim(variable_get('pathauto_node_pattern', FALSE));
    }

    // If there is a pattern AND the user is allowed to create aliases AND the path textbox is present on this form
    if (!empty($pattern) && user_access('create url aliases') && isset($form['path']['path'])) {
      $output = t('An alias will be generated for you. If you wish to create your own alias below, untick this option.');
