Force specific language?

[sfieux]

I'm trying to force the use of english for my installation of self-service-password. It seems that this piece of code from index.php is causing my trouble:

require_once("conf/config.inc.php"); # contains line $lang ="en"; 
(...)
$lang = detectLanguage($lang, $languages);
require_once("lang/$lang.inc.php");

The way I understand it is: the language is defined in config.inc.php, and afterwards this information is discarded to read it from browser settings in detectLanguage.

Am I missing something?

If I'm not, would you be interested in a PR to change this behaviour? I would change the default language value to "auto" in config.inc.php and only try to detect the browser language if the value is different:

if ( $lang == "auto" ) {
    $lang = detectLanguage($lang, $languages);
}
require_once("lang/$lang.inc.php");
if (file_exists("conf/$lang.inc.php")) {
    require_once("conf/$lang.inc.php");
}

Maybe the best would be to configure a list of authorized languages. Then this would require a new parameter which will be an array. If it is empty, all available languages will be authorized, else this parameter will be used to limit which languages could be used.

What would be the expected behaviour when several languages are authorized but the detected one is not part of the list? Une the first authorized one? Use initial $lang value?

[coudot]

if the lang is not one authorized, then fall back to default lang

I'm closing this issue because the PR was merged.
Thank you for your contribution @sfieux.

No problem, I'm the one who needed it :)
