Drupal多语言网站在中文语言浏览器的自动本地化
Drupal 6 的核心文件根目录 includes 文件夹下有一个 language.inc 的文件, 它的里面主要是 Drupal 网站语言控制的代码, 包括语言前缀, 浏览器语言判断等等.
在 Drupal 网站系统里面中文语言的默认前缀是 zh-hans, 一般形式如 http://域名/zh-hans/... . 而浏览器的语言, 以中文版 Firefox 为例 : 中文的语言的选择仅有
汉语 [zh];
汉语/新加坡 [zh-sg];
汉语/中国 [zh-cn];
汉语/中国台湾 [zh-tw];
汉语/中国香港 [zh-hk].
当 Drupal 在用 zh-hans 匹配时, 无法找到匹配的浏览器中文语言选择. 所以你会发现虽然在 Drupal 语言配置选择了 : 使用路径前缀，及后备语言(先通过检查路径中的语言代码，或与每种语言所定义的路径前缀相匹配的字串，来决定站点使用哪种语言显示。如果没有找到合适的前缀，则使用当前用户我的帐号页面中的偏好语言设置，或者使用用户浏览器的偏好语言设置。如果没有找到任何用户定义的偏好语言设置，则使用默认语言。) 还是不能匹配到浏览器设置的中文语言.
有两种方法解决这个问题,
第一种:后台修改语言前缀字符串, 这个修改起来非常简单 :
管理路径 admin/settings/language/edit/zh-hans
将路径前缀该为和浏览器可以匹配的一个, 如 zh 或 zh-cn.但是只能匹配一个.
第二种:直接修改 includes 下的 language.inc 文件, 加入代码判断, 把 zh 开头的都视为是 zh-hans 中文语言. 例如在language_from_browser()函数里加入:
foreach($browser_langs as $langcode=>$q) {
if(is_integer(strpos($langcode, 'zh'))) {
$browser_langs['zh-hans'] = $q;
unset($browser_langs[$langcode]);
}
下面是修改后的language.inc的全部代码:

嗯 为了统一没有做繁体中文，汉语只做了简体中文。
