Hi all,

I have installed ubercart with the module cart links enabled, and want to add a product, and then empty the cart, without the notification message if there is already something in the cart. therefore we have this hook in uc_cart_links:


/**
 * Preprocesses a Cart Link and confirm with the user if a destructive action
 * is included.
 *
 * @see uc_cart_links_form_submit()
 */
function uc_cart_links_form($form, &$form_state, $arg1) {
  // Fail if the link is restricted.
  $data = variable_get('uc_cart_links_restrictions', '');
  if (!empty($data)) {
    $restrictions = explode("\n", variable_get('uc_cart_links_restrictions', ''));
    $restrictions = array_map('trim', $restrictions);

    if (!empty($restrictions) && !in_array($arg1, $restrictions)) {
      $url = variable_get('uc_cart_links_invalid_page', '');
      if (empty($url)) {
        $url = '<front>';
      }
      unset($_GET['destination']);
      drupal_goto($url);
    }
  }

  // Confirm with the user if the form contains a destructive action.
  
  $items = uc_cart_get_contents();
  if (variable_get('uc_cart_links_empty', TRUE) && !empty($items)) {
    $actions = explode('-', urldecode($arg1));
    foreach ($actions as $action) {
      $action = drupal_substr($action, 0, 1);
      if ($action == 'e' || $action == 'E') {
        return confirm_form(array(), t('The current contents of your shopping cart will be lost. Are you sure you want to continue?'), variable_get('uc_cart_links_invalid_page', ''));
      }
    }
  }

  // No destructive actions, so process the link immediately.
  uc_cart_links_process($arg1);
}

and now I want to alter, or overwrite it all together. I need to comment out the part 

$items = uc_cart_get_contents();
  if (variable_get('uc_cart_links_empty', TRUE) && !empty($items)) {
    $actions = explode('-', urldecode($arg1));
    foreach ($actions as $action) {
      $action = drupal_substr($action, 0, 1);
      if ($action == 'e' || $action == 'E') {
        return confirm_form(array(), t('The current contents of your shopping cart will be lost. Are you sure you want to continue?'), variable_get('uc_cart_links_invalid_page', ''));
      }
    }
  }

But don't want to hack into the code?

This seems to be easy to do, but can someone help me, because I am not so good in modules. I only need the proper hook function and the right implementation of that hook function
