基于 $_SESSION 的语言选择无法正常工作

$_SESSION based language selection is not working properly

我的网站有两种语言:英语和俄语。这些语言的数据库名称是 EN 和 RU。

我使用旧的 php+smarty 脚本。此脚本的默认语言选择代码如下:

if(!isset($_SESSION)){
    define('LANGUAGE_ID', 'EN');
} else if ($_SESSION['language'] == '')
{
    define('LANGUAGE_ID', 'EN');
} 

当我想看俄语页面时,我会像这样访问带有语言短语 (?language=RU) 的任何页面:

http://www.example.com/index.php?language=RU

但是这些页面首先不会以俄语加载。当我单击另一个 link 或刷新页面时,页面以俄语加载。保存 cookie 后,我可以在第一次访问时看到俄语页面。但是如果我删除浏览器中的 cookie,那么我在第一次访问时就看不到俄语了。

我尝试了很多组合,但找不到任何解决方案。你有什么主意吗?

非常感谢...

编辑:

我在 main.class.php 中找到了一些代码:

function __construct($dbh,$smartyBuild) {
    $this->dbh = $dbh;
    $this->sitevar = @$smartyBuild->FetchSiteVar();
    $this->smartybuild = @$smartyBuild;

    if($_REQUEST['language'] !='')
    {
        $_SESSION['language'] = $_REQUEST['language'];
    }
    else
    {
        $langaugeAlready = mysql_fetch_array(mysql_query("select value from ".TABLE_PREFIX."sitevars where array_key = 'default_language_feed'"));

    if($_SESSION['language'] == '')
    {

        $_SESSION['language'] = $langaugeAlready['value'];

    }

}
if($_SESSION['language'] !='' )
{
    define('LANGUAGE_ID', $_SESSION['language']);
}
else
{
    define('LANGUAGE_ID', 'EN');
    $_SESSION['language'] = 'EN';
}

}

问题与这些代码有关吗?

就像我说的,如果没有所有代码,我们只能猜测问题出在哪里,但是,这里...

您似乎只检查语言的 $_SESSION 变量而不是 $_GET 变量(从 URL 获取语言)。因此,该值只会在您刷新页面后发生变化。

试试这个。我假设您的意图是将英语显示为默认值,如果它在 url 中定义,则仅显示俄语,但一旦定义为保留该语言,直到它再次放入 URL。

 //start a session. must be called first on all pages you want it to work on

 session_start();


 //first check if there's a new language coming from the URL

 if(isset($_GET['language']))
     {
     // if we have a new language setting from the URL, check which one and save it in the session.
     // we check it is EN or RO before saving into the session since I don't know what you're using it for later. eg part of a DB query which would be a security risk if it is anything other than EN or RO.

     if($_GET['language'] == 'EN')
           {
           $_SESSION['language'] = 'EN';
           }
     if($_GET['language'] == 'RO')
           {
           $_SESSION['language'] = 'RO';
           }

     } 


 //now check the session variable, which will have been updated above if changed     

 if(isset($_SESSION['language']))
     {
     // already have a language saved, so let's use it

     define('LANGUAGE_ID', $_SESSION['language']);

     }
 else
     {
     // no language from URL and no language saved, so default to english

     define('LANGUAGE_ID', 'EN');
     }
