I'm trying to build a website which will be able to support two languages, English and Spanish. I'm still starting with all this website creation thing, so I spent a lot of time trying to find a tutorial on localization that I could understand. Finally, I found one which looked very interesting (http://www.webreference.com/programming/php/localization/index.html), but that didn't work. When using
<? echo WELCOME_TXT ?>
on the title, it actually displays that code line instead of the WELCOME_TXT text. I've tried using "WELCOME_TXT", constant("WELCOME_TXT"), etc and none has worked. What am I doing wrong?
Here's my code: lang.php
<?php
if ($_SESSION[lang] == "") {
$_SESSION[lang] = "en";
$currLang = "en";
} else {
$currLang = $_GET[lang];
$_SESSION[lang] = $currLang;
}
switch($currLang) {
case "en":
define("CHARSET","ISO-8859-1");
define("LANGCODE", "en");
break;
case "de":
define("CHARSET","ISO-8859-1");
define("LANGCODE", "de");
break;
case "ja":
define("CHARSET","UTF-8");
define("LANGCODE", "ja");
break;
default:
define("CHARSET","ISO-8859-1");
define("LANGCODE", "en");
break;
}
header("Content-Type: text/html;charset=".CHARSET);
header("Content-Language: ".LANGCODE);
?>
txt.php
<?php
function defineStrings() {
switch($_SESSION[lang]) {
case "en":
define("WELCOME_TXT","Welcome!");
define("CHOOSE_TXT","Choose Language");
break;
case "de":
define("WELCOME_TXT","Willkommen!");
define("CHOOSE_TXT","Sprache auswählen");
break;
case "ja":
define("WELCOME_TXT","[ Japanese characters here]");
define("CHOOSE_TXT","[ Japanese characters here]");
break;
default:
define("WELCOME_TXT","Welcome!");
define("CHOOSE_TXT","Choose Language");
break;
}
}
?>
index.php
<?
session_start();
include("lang.php");
include("txt.php");
defineStrings();
?>
<HTML>
<HEAD>
<TITLE><? echo WELCOME_TXT ?></TITLE>
<META HTTP-EQUIV="Content-Type" content="text/html; charset=<? echo CHARSET; ?>">
<META HTTP-EQUIV="Content-Language" content="<? echo LANGCODE; ?>">
<BODY>
<h1 align=center><? echo WELCOME_TXT; ?></h1>
<p align=center><strong><? echo CHOOSE_TXT; ?></strong><br><br>
<a href="<? echo $_SERVER[PHP_SELF].'?lang=en'; ?>"><img src="en_flag.gif" border=0></a>
<a href="<? echo $_SERVER[PHP_SELF].'?lang=de'; ?>"><img src="de_flag.gif" border=0></a>
<a href="<? echo $_SERVER[PHP_SELF].'?lang=ja'; ?>"><img src="ja_flag.gif" border=0></a>
</p>
</BODY>
</HTML>
(I know it's the tutorial code, but it doesn't work for me neither)
