Load site in correct language uppon browser settings

[lapinkulta]

Hi!

My second question today 

I would like to suggest a mod that loads the correct language according to the browsers language.

Example:

If a user visits http://www.domain.com/

and his browser settings are german he should be directed to

http://www.domain.com/?l=deutsch

if english than

http://www.domain.com/?l=english

if any other language that is not installed:

http://www.domain.com/l=?english (so the standard language)

How this will be possible?

I have tried to use code that I use in smarty project (where it works fine).

Code: [Select]

<?php

if (empty($_GET['l'])) {
if(strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-at") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-ch") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-li") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-lu")) {
Header("Location: ./index.php?l=deutsch");
}
elseif(strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"en") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"en-us")) {
Header("Location: ./index.php?l=english");
}
else {
Header("Location: ./index.php?l=english");
}
}

?>

I have tried to insert in on top of index.php and page_header.php but I get only lot of errors like:

Warning: Cannot modify header information - headers already sent by (output started at /****/index.php:2) in /****/index.php on line 6

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /****/index.php:2) in /****/includes/sessions.php on line 84

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /****/index.php:2) in /****/includes/sessions.php on line 84

Warning: Cannot modify header information - headers already sent by (output started at /****/index.php:2) in /****/includes/sessions.php on line 92

Warning: Cannot modify header information - headers already sent by (output started at /****/index.php:2) in /****/includes/sessions.php on line 92


I think to code is allright, just the place where I tried to include it is wrong. If somebody could point me where it would need to be included, I would be happy.

1) if you include a code in a .php file, do not use additional <?php and ?> if they are already present there.
2) try insert that code into global.php, because that file being executed with any pages. You should added above:

Code: [Select]

$cat_cache = array();3) ones its done, make sure you didnt leave any spaces or newlines before <?php and after ?> otherwise you'll get the same error messages.

thanks, that's the correct place to include...

Hi lapinkulta,
did you find a solution for your request?
Im very interested.

Hi Matthias!

If you place my code where Vano said, it works quite fine.

Only problem, but nothing to to with this code, is that for the standard language no l=english string is attached.
See: http://www.4homepages.de/forum/index.php?topic=6729.120

I'm waiting for a solution on that...

Hi lapinkulta,
thanks a lot.
Works fine.
Only my cookie for the last language settings is not working anymore.
But I think with your mod it is useless anyway.

Matthias

[Matthias70]

Ups I was a bit to fast.
Mod works fine but my default-links
like: .../bildergalerie/categories.php?cat_id=35
are now all redirected to index.php. 

Only links which include the language settings are working
like: .../bildergalerie/details.php?image_id=313&l=deutsch

Do you have any solutions for that

Matthias

[lapinkulta]

That the problem I addressed in my last posting. What I have done is a small change in the sessions.php in order that even for the standard language the "l=language" is attached.

find

Code: [Select]

    if (!empty($l)) {
      $url .= strpos($url, '?') !== false ? $amp : "?";
      $url .= "l=".$l;
    }

and replace with:

Code: [Select]

   if (!empty($l)) {
      $url .= strpos($url, '?') ? '&' : '?';
      $url .= "l=".$l;
   }
   if (empty($l)) {
      $url .= strpos($url, '?') ? '&' : '?';
      $url .= "l=english";
   }

be sure to change "english" to whatever is your standard language.

works fine with me.

greetings,

Mmh, is there no solution that keeps the default links
I tried it with this code. Just without the language extension "?l=deutsch" in the fifth line, but it's not working 

Code: [Select]

if (empty($_GET['l'])) {
if(strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-at") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-ch") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-li") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"de-lu")) {
Header("Location: ./index.php");
}
elseif(strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"en") || strstr($_SERVER["HTTP_ACCEPT_LANGUAGE"],"en-us")) {
Header("Location: ./index.php?l=english");
}
else {
Header("Location: ./index.php?l=english");
}
}

[lapinkulta]

Not with this code as

Code: [Select]

if (empty($_GET['l'])) { ....

in the first row checks if there is a language specified in the URL. If not, it will always choose the language based on browser setting.

[V@no]

Code: [Select]

if ((!isset($HTTP_GET_VARS['l']) || empty($HTTP_GET_VARS['l'])) && (!isset($HTTP_POST_VARS) || empty($HTTP_POST_VARS))) {
  $lang_array = array(
      "de" => "deutsch",
      "de-at" => "deutsch",
      "de-ch" => "deutsch",
      "de-li" => "deutsch",
      "de-lu" => "deutsch",
      "en" => "english",
      "en-us" => "english",
  );
  foreach($lang_array as $key => $val)
  {
    if (strstr($HTTP_SERVER_VARS["HTTP_ACCEPT_LANGUAGE"],$key))
    {
      $l = $val;
      break;
    }
  }
  $l = ($l) ? $l : "english";
  Header("Location: ".$HTTP_SERVER_VARS['REQUEST_URI'].(strstr($HTTP_SERVER_VARS['REQUEST_URI'], "?") ? "&" : "?")."l=".$l);
  exit;
}

Hi Vano!

With this code I can not access the admin area anymore...

Greetings,

[Matthias70]

Hi V@no and lapinkulta
the code works fine for me. No admin problems and at the moment no other problems with the language settings 

Thanks a lot
Matthias

Hi V@no,
Perhaps it is the wrong place for this post.
But after the code changes above the code for my "new multilang images outside 4images" is not working anymore

Here the code. Perhabs there is a conflict with the changed global.php

Code: [Select]

<?php
// PATH to your 4images Gallery / PFAD zu Ihrer 4images Gallerie
define('SCRIPT_URL', 'http://www.*****/bildergalerie/');
define('ROOT_PATH', '/*****/bildergalerie/');
include(ROOT_PATH.'config.php');
include(ROOT_PATH.'includes/db_mysql.php');
include(ROOT_PATH.'includes/constants.php');
$site_db = new Db($db_host, $db_user, $db_password, $db_name);
function is_remote($file_name) {
  return (preg_match('#^https?\\:\\/\\/[a-z0-9\-]+\.([a-z0-9\-]+\.)?[a-z]+#i', $file_name)) ? 1 : 0;
}
$sql = "SELECT a.image_id, a.cat_id, a.image_name, a.image_active, a.image_thumb_file, a.image_hits
        FROM ".IMAGES_TABLE." a, ".CATEGORIES_TABLE." b
        WHERE a.image_active=1
        AND a.cat_id = b.cat_id
        AND b.auth_viewcat=".AUTH_ALL."
        AND b.auth_viewimage=".AUTH_ALL."
        ORDER BY image_date DESC
        LIMIT 3";
$result = $site_db->query($sql);
while ($row = $site_db->fetch_array($result)) {
$image_id = $row['image_id'];
$cat_id = $row['cat_id'];
$image_name = $row['image_name'];
$image_hits = $row['image_hits'];
$thumb_src = (is_remote($row['image_thumb_file'])) ? $row['image_thumb_file'] : SCRIPT_URL.THUMB_DIR."/".$cat_id."/".$row['image_thumb_file'];
echo "<a href=\"".SCRIPT_URL."details.php?image_id=$image_id\" target=_parent><img src=\"".$thumb_src."\" border=\"0\"></a>\n";
echo "<br><b>$image_name</b><br>\n";
echo "Hits: $image_hits<br><br>\n";
}
?>
