Multilingual page problems

[pedro84]

Hello again!

I'm PHP  neewbie, but I'm writing my first website, with huge help from good people. I have problem. I want to make multilingual site based on lang files

[code]define ('LOGIN', "Login");[/code]

But I don't know how to start, I found some articles over the internet, but I don;t understand them:)

Greetings,

index.php
[code]
<?php

define("LANGUAGE", "EN");
require_once("include/language/". LANGUAGE .".inc");

echo "<h1>". WELCOME_MESSAGE ."</h1>";

?>
[/code]

EN.inc
[code]
<?php

define("WELCOME_MESSAGE", "Welcome to the site");

?>
[/code]

Then based on what LANGUAGE is set to, it will load a difference language file.

Thank You.

But how to make lang switcher?

[heckenschutze]

Usually, an array of strings is used, since constants cannot be redefined.

eg:

EN,
[code]<?php
$language["welcome"] = "Welcome";

?>[/code]

DE,
[code]<?php
$language["welcome"] = "Hallo"; // lols i dunno german :P

?>[/code]

then use something like:
[code]<?php
define("LANGUAGE", "EN");
require_once("include/language/". LANGUAGE .".inc");
echo $language["welcome"];
?>[/code]

HTH!

[xsist10]

You can do the language selector like so

[code]
<?php
$lang = addslashes($_GET["lang"]);
require_once("include/language/". $lang .".inc");
echo $language["welcome"];

?>

<form action='index.php' method='get'>
<select name='lang'>
<option value='EN'>English</option>
</select>
<input type='submit' value='Change Language'>
</form>

[/code]

[pedro84]

[code]<?php
$lang = addslashes($_GET["lang"]);
require_once("include/language/". $lang .".inc");
echo $language["welcome"];

?>

<form action='index.php' method='get'>
<select name='lang'>
<option value='EN'>English</option>
</select>
<input type='submit' value='Change Language'>
</form>
[/code]

I use this for test and i get error

[code]
Warning: main(include/language/.inc): failed to open stream: No such file or directory in c:\usr\apache\httpd\html\index.php on line 3

Fatal error: main(): Failed opening required 'include/language/.inc' (include_path='.') in c:\usr\apache\httpd\html\index.php on line 3[/code]

I've got files made.

BTW Have I put this code :

[code]<?php
$lang = addslashes($_GET["lang"]);
require_once("include/language/". $lang .".inc");
echo $language["welcome"];

?>[/code]
in all my pages?

[heckenschutze]

xsist10's method is prone to URL injection.

Think about it, what if ?lang= was defined as ../../../veryimportantpasswordfile or somesuch... ?

Better off to employ swtiches...

eg,
on all your pages:
[code]<?php
require_once("langman.php");
if(!SelectLanguage($_GET["lang"]))
die("Error selecting language!");

echo $language["welcome"];
?>[/code]

then in langman.php:
[code]
<?php
$language = array();

function SelectLanguage($strLang)
{
global $language;

$inc = "en";
switch(stripslashes($strLang))
{
case "de":
$inc = "de";
break;

case "en":
$inc = "en";
break;

default:
$inc = "en";
}


include_once("languages/" . $inc . ".inc");
if(isset($lang))
{
$language = $lang;
return true;
}

return false;
}
?>
[/code]

Then in ./languages/en.inc for example:
[code]<?php
$lang["welcome"] = "welcome";
?>[/code]

and ./languages/de.inc :
[code]<?php
$lang["welcome"] = "hallo";
?>[/code]

If your unsure how to apply this, just ask ;)

Then to select the language, just use mypage.php?lang=de on ALL your pages, where you are using language, if ?lang is not defined, english will be used.

hth.

[pedro84]

Thank You.

I apply what You write and I get blank page.

What did I make wrong?

[heckenschutze]

Haha, I spelt welcome wrong :s, sorry Try it now... :D

[pedro84]

It works now. Thank You veerry much. You are verny nice human!

But tell me one thing...how to select language??:>:)

[heckenschutze]

Well, the method above is simple but can become confusing in large sites... (Since ?lang= has to be appended to every link)...

Ideally, you should store the users language in a session...

Meaning on the top of every page you would place:
[code]<?php
session_start();
require_once("langman.php");
if(!SelectLanguage($_SESSION["lang"]))
die("Error selecting language!");

echo $language["welcome"];
?>[/code]

Then setlang.php :
[code]<?php
session_start();
$strLang = $_GET["lang"];
$_SESSION["lang"] = stripslashes($strLang);
header("Location: index.php"); //** redirect to where u want...
?>[/code]

Then!, create links to change the language:
[code]<a href="setlang.php?lang=de">German</a><br />
<a href="setlang.php?lang=en">English</a>[/code]

Tell me how that pans out... :)

hth.

[pedro84]

t works ;D ;D ;D
Thank You very muuuch!!

I'm sure I will have problem later:) I'll post here ok?:)

[heckenschutze]

Yeah just make a new topic... :P

No probs :P

[pedro84]

I knew it:)
When I put it on my site, it works, but i get this error:
[code]Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at c:\usr\apache\httpd\html\index2.php:2) in c:\usr\apache\httpd\html\index2.php on line 3[/code] too.

Whats wrong?:>:)

[heckenschutze]

[url=http://php.net/session_start]session_start()[/url]; MUST be called before any output is sent to the browser (eg spaces or HTML), [url=http://php.net/session_start]session_start()[/url] should idealy be the topmost thing in your website. The manual also mentions this :)

hth.

[pedro84]

OMG...what a asshole:) I'm:)

Thank You
You know what? You are veeery kind to me:)

session_set doesnt exist as a function, but otherwise you're right. it's [url=http://www.php.net/session_start]session_start[/url] instead.

cheers

[heckenschutze]

Im kind to everyone... im told ;)
No probs helping... First time ive written a multi-lingual system :P

Sorry, my bad, just got back into php after a year off (CGI instead):P

[pedro84]

One question:

I incude some scripts with this code:
[code]<?php
if (isset($_GET['op'])){
switch ($_GET['op']) {
case 1:
    include("content1.php");
  break;
case 2:
  include("content2.php");
  break;
case 3:
include ("sendtofriends/sendtofriends.php");
  break;   
default:
      include("news/show_news.php"); // this stops pageid to be set by the user trying to break your script
}
}

else {
include ("news/show_news.php");  //this one allows for just index.php to get default page
}
?>[/code]

Can I make them mulitlingual the same way? Or make each module lang file?

Thanks in Advance

[True`Logic]

basically youll need to include a file which has an array of the english word into the other language, then split your dialogues into an array on chr(32), after that you only need to use str_replace($words[$num], $lang[$words[$num]]) in a while statement =)

[pedro84]

Could You write clearly for me?  ??? ??? 8)

[pedro84]

Someone know how to apply it in some scripts?

[pedro84]

Does anyone knows?
