Question

hello i have a question how to use sessions.

i would like to change the language of a site. so the logic of the language settings is the following:

when calling my site it will be checked, if there is a browser_accept_language.
if there is a language setting it will be used as a preferred language otherwise the default language is set.
in the next step it will be checked if there is already a setting for it stored in a session.
if there is a session value for language the preferred language will be changed to the session entry.

okay, that is the logic part. now i tried to code. the problem is that it seems not working and i have no clue why.

so the php is:

<?PHP       
    session_start();

    header ("Content-Type: text/html; charset=utf-8");


    include_once "scripts/db_connect.php";

if (isset($_SERVER["HTTP_ACCEPT_LANGUAGE"])){
    $max   = 0.0;
    $languages = explode(",", (strtolower($_SERVER["HTTP_ACCEPT_LANGUAGE"])));
    foreach($languages as $language){
        $language = explode(';', $language);
        $q    = (isset($language[1])) ? ((float) $language[1]) : 1.0;
        if ($q > $max){
            $max = $q;
            $pref_language = $language[0];
        }
    }
    $pref_language = trim($pref_language);
}

$_SESSION['language'] = $pref_language_changed;

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

    $pref_language = $pref_language_changed;

}...

followed by some html for mainwrapper the footer:

if ($pref_language === "af" OR $pref_language === "en"{
    $footer = "footer1";
    }else{
        $footer = "footer2";
    }

include_once "../scripts/".$footer.".php";

and the footer itself is:

        ... <ul class="flag">
                <li id="'.$language_flag.'">
                    <ul class="drop_down">
                        <form action="'.$_SERVER['PHP_SELF'].'" method="post">
                            <a href="/foo"><li id="one"><div>language1</div></li></a>
                            <a href="/bar"><li id="two"><div>language2</div></li></a>
                        </form>
                    </ul>
                </li>
             </ul>...
<!--Footer -->';    


if (isset($_POST['one'])){
    $_SESSION['language'] = "language1";
    }
if (isset($_POST['two'])){
    $_SESSION['language'] = "language2";
    }
?>

this is what all my pages are built of.

if there is someone who could tell me how to use sessions i really would appreciate.

thanks alot.

Answer 1

Try this

<ul class="drop_down">
    <form action="'.$_SERVER['PHP_SELF'].'" method="post">
        <li><input type="submit" name="one" value="language1"></li>
        <li id="two"><input type="submit" name="one" value="language2"></li>
    </form>
 </ul>

Also when you want to link an <li>
use

<li><a href="/foo">Link</a></li>

Dont use the a href outside the <li>
