This module provides access checking of the current language of the site with the language of the content (language neutral are not considered).

Code

function _content_language_access_node_access($op, $node, $account = NULL, $old_callback = NULL) {
  global $user;
  global $language;

  // If no user object is supplied, the access check is for the current user.
  if (empty($account)) {
    $account = $user;
  }

  // User #1 has all privileges:
  if ($account->uid == 1) {
    return TRUE;
  }

  // Convert the node to an object if necessary:
  if ($op != 'create') {
    $node = (object) $node;
  }
  if ($old_callback != NULL && function_exists($old_callback)) {
    $access = $old_callback($op, $node, $account);
  }
  else {
    $access = node_access($op, $node, $account);
  }

  // Bypass completely if access returns false.
  if (!$access) {
    return FALSE;
  }

  // Only checks for view permission.
  if ($op != 'view') {
    return TRUE;
  }
  if ($node->language) {

    // Verifies if the current language is the same of the content.
    if ($node->language == $language->language) {
      return TRUE;
    }
    else {

      // Checks the configuration defined in admin page.
      $config = _content_language_access_get_config();
      $actual_language_permission = isset($config[$language->language][$node->language]) ? $config[$language->language][$node->language] : FALSE;
      if ($actual_language_permission) {
        return TRUE;
