すべてのページの上部に挿入したい次のコードに問題があります。主な目標は、言語設定を変更することです。問題は、フォームを投稿すると、セッションが変更されないことです。
<?php
session_start();
$basename = basename($_SERVER['SCRIPT_NAME'], ".php");
$host = $_SERVER['HTTP_HOST'];
$index_path = $host.'/'.$basename;
if (isset($index_path)){
//header ('Location:http://www.domain.com/'.$pref_language.'/'.$basename);
}
if (!isset($_SESSION['pref_lang'])){ //looks if this session already exists
if (isset($_SERVER["HTTP_ACCEPT_LANGUAGE"])){//looks if the browser has set a default 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);
}
if (!isset($_SERVER["HTTP_ACCEPT_LANGUAGE"])){// in case there is no http_accept_language create it by hand
$pref_language = "de";
}
$_SESSION['pref_lang'] = $pref_language; //registers the session in case there is no one
$pref_language = $_SESSION['pref_lang']; //is needed to select the right footer
}else{ //in case that there is already a session with the saved language
if (isset($_REQUEST["fr"]) ) { //if a new language will be choosen overwrite the old session with the new entry and header to correct path to show the page in the desired language
$_SESSION['pref_lang'] = 'fr';
header ('Location: http://www.domain.com/'.$pref_language.'/'.$basename);
}elseif (isset($_REQUEST["en"]) ) {
$_SESSION['pref_lang'] = 'en';
header ('Location: http://www.domain.com/'.$pref_language.'/'.$basename);
}
$pref_language = $_SESSION['pref_lang']; //needed in case that the path is correct to select the right footer version
}
var_dump($_POST);
var_dump($_SESSION);
echo '<form method="post">
<input type="submit" id="en" name="en" value="en"/><div>englisch</div>
</form>
<form method="post">
<input type="submit" id="fr" name="fr" value="fr"><div>französisch</div>
</form>';
?>
いつ
print_r ($_SESSION);
別の空白ページでは、セッションはデフォルトの「de」になりますか?
私を助けてくれる人がいれば、本当に感謝しています。
どうもありがとう。
