How coppermine stores language settings?

[maolu]

Hi everybody.

I'm trying to understand the way used in coppermine to store the language selected by a user.
How can it remember the last language you selected and show the gallery in that lang at the next visit?
Is it a cookie?!?

And in what part of the code can i find the commands that read this information?

Thankyou a lot.

Is it a cookie?!?

yes

[maolu]

ok thx.
So how can i get, via php, the language stored in this cookie?

[Joachim Müller]

The user language is stored in

Code Select Expand

$USER['lang']To get a list of everything that coppermine "knows" about a user, try

Code Select Expand

print_r($USER);

[maolu]

i tried with

Code Select Expand

echo $USER['lang'];
but i get a costant result "r"

Right now i tested reading directly the cookie and it seems to work

Code Select Expand


$decoded = base64_decode($cpg133_data);
$lines = explode (":",$decoded);
$lastline = array_pop($lines);
$pieces = explode("\"",$lastline);
$currentLanguage = $pieces[1];

OK, i have still problem with this issue... :\'( :\'( :\'(

The purpose is to be able to get and set the language values used in the gallery.
The reason is that i want to have also other pages in my site and of course if someone (I.E.) selects "english language" for the "LINKS" page, the same language has to be set also for the Coppermine Gallery and viceversa.

Right now the only functioning method i found in order to GET the language, as explined before,  is this:

Code Select Expand

function my_get_language($cookie)
{
    $decoded = base64_decode($cookie);
    $lines = explode (":",$decoded);
    $lastline = array_pop($lines);
    $pieces = explode("\"",$lastline);
    $currentLanguage = $pieces[1];
    return $currentLanguage;
}


In order to SET the language i use this method:

Code Select Expand

function my_set_language($cookieName, $cookie, $newLang)
{
    //GETS CURRENT LANGUAGE
    $decoded = base64_decode($cookie);
    $lines = explode (":",$decoded);
    $lastline = array_pop($lines);
    $pieces = explode("\"",$lastline);
    $currentLanguage = $pieces[1];
   
    //CREATES STRING WITH NEW LANGUAGE INFORMATION
    $decoded = base64_decode($cookie);
    $nonLanguageText = explode($currentLanguage, $decoded);
    $newLanguageString = base64_encode($nonLanguageText[0].$newLang.$nonLanguageText[1]);
   
    //SETS THE COOKIE WITH NEW LANGUAGE SETTINGS
    setcookie ($cookieName, $newLanguageString, time() + 86400, "/");
   
}


The problem is that right now it's not working...
So i tryed as a test to simply delete the Coppemine cookie using this:

Code Select Expand

setcookie("cpg133_data", "", time() - 3000, "");

But this is not worknig too, so i assume i'm not catching the point of the problem.
Can you help me?

Of course any kind of simpler solution is more then well accepted and if you say me "ehi you stupid, don't you know that you can use the function setGalleryCookieEasyer()!!" i'll be happy to hear that!

Look at the lang handling code in include/init.inc.php

[maolu]

you mean this?

Code Select Expand

if (isset($USER['lang']) && !strstr($USER['lang'], '/') && file_exists('lang/' . $USER['lang'] . '.php')) {
    $CONFIG['default_lang'] = $CONFIG['lang'];          // Save default language
    $CONFIG['lang'] = strtr($USER['lang'], '$/\\:*?"\'<>|`', '____________');
} elseif ($CONFIG['charset'] == 'utf-8') {
    include('include/select_lang.inc.php');
    if (file_exists('lang/' . $USER['lang'] . '.php')) {
        $CONFIG['default_lang'] = $CONFIG['lang'];      // Save default language
        $CONFIG['lang'] = $USER['lang'];
    }
} else {
    unset($USER['lang']);
}

By now it's not so clean to me how to use this if i want to set/get the language from outside the gallery's php files.
:-\\

I mean, what could i do?
From a custom php file can i set language this way?

Code Select Expand

$CONFIG['lang'] = "english"

Am I missing something?

[maolu]

Really no one knows it?

Somebody can tell me the reason why i cannot write into the Coppermine's cookies?

thx.

If you need custom information to be written, write your own cookie - don't abuse coppermine's cookie.

Did you read what i wrote?!?!

No custom information, i'm talking about the selected language. I only want to use the selected coppermine language also outside of the galley, this way unifying it in all my site.
