thanks to you both for your suggestions, which actually go even further than I originally had in mind.
The idea of pbötcher is nice, as it allows defining a specific language for the user.
To accomplish what Jan suggested, I propose a solution which I have used ... more than 10 years ago. Today there might be more elaborate codes, but this works quite nice and could be used to also show the login page automatically in a user preferred language.
Side note: Writing this, the question comes in mind, why not simply place a drop down with all available languages at the login page. When the user selects a language, the (language) form is submitted and the login page reloaded with the new language applied.
As you see near the end of function get_languages, in this code the user is being redirected to some page. This can be changed easily to set a language string variable, either in PHP and/or in the session.
) would receive the German language (if installed) - if not installed he would get the default: English.
Someone from Italy (proably IT) would receive Italian automatically. If no accept-language is sent: Default - English.
In addition There might be also the option (as described above to use a dropdown). This seems useful, as people might be using some predefined system with a accept-language which they (the actual person) does not prefer.
Code: Select all
