Keep users default language after Login

Hello,
My site is in 4 languages, I am using WPML.
When p.e. a chinese member is logging in, I would like him to stay in his language and not to be redirected to my default language which is french.
I am stuck now with the login. I am all the time redirected to french whatever Login option I choose under

General options => Login Welcome Page: 

But I suppose there could be a possibility to keep the language from which the login took place?
Members are entirely added manually by the site manager.
So maybe could I give the members some special tags for their native language whilst adding them?

Could you give me an advice? I would also bite me through some php.
Any help would be great.
Thank you very much in advance.
Nadia

Maybe I should add the login widget via php?
Would this offer more choice for the language?
Sorry, I think I have to push this a bit as I posted accidentally in the community forum at the beginning;)

Thank-you for your inquiry. ~ We’re very sorry for the delay.

Hello,
thank you very much for your answer,
the delay was absolutely my fault, I posted in the wrong forum.

I am not sure if I got you right. I am a bit confused by your answer.

( Translating s2Member does not work via adding .po and .mo files?)

Could you maybe explain a bit more how this would help me to keep the chosen language?

p.e. if I log in via my english login widget I am redirected to my french Login Welcome Page.
How can I achieve to be directed to my english Login Welcome Page? (or chinese, japanese?) with your proposed method?
Kind regards

Hello,
Could you maybe look at my question once again?
I am not sure your answer matches my question.
I do not need advice for translation but for redirection to members default language?
Is there a possibility?
Someone posted this and it goes in the right direction I think,
but maybe you could help me?

Ok, another idea, could I simply remove the redirection to the Login Welcome Page and stay on the same page from where the login took place? Would this help to keep the language which was chosen by the user?
Thank you very much
I tried to put this piece of code in the mu plugin folder

<?php
add_filter ("ws_plugin__s2member_login_redirect",  '__return_false', 10, 2);
?>

and called it hook.inc.php.
I do not have any idea about php but this is what I tried after searching the forum.
It is not working but as I already said I am a php dummy;)
But as far as I read in the forum this could be possible?

Thanks for the follow-up. ~ We appreciate your patience.

( Translating s2Member does not work via adding .po and .mo files?)

s2Member is compatible with translation through .po and .mo files with WordPress I18n translation. Find info on this here:

Pre Sale FAQs » Can s2Member® be translated into other languages?

The reason I recommend translation through PHP as shown in the Article I posted in my previous reply is that you do not have to have your WordPress installation in a specific language for the files to work.

I’m not absolutely certain how the translation works with WPMU, but because you’re hoping to have your site automatically translated based on a User’s preference, I would recommend adding a Custom Profile/Registration Field for a User’s language, and then using this field’s value to decide the language that you should translate your site into.

See: Dashboard -› s2Member® -› General Options -› Registration/Profile Fields

Once you have made this field, you can then grab the field’s value with the get_user_field() function. You might do something like this:

p.e. if I log in via my english login widget I am redirected to my french Login Welcome Page.
How can I achieve to be directed to my english Login Welcome Page? (or chinese, japanese?) with your proposed method?

For this, I would recommend (instead of having multiple pages), to use the same approach that I showed above, and check for the User’s language, and display the correct language based on what they have set up.

Remember that you will need a PHP Execution plugin to use PHP in a Post/Page.

Thank you for your answer.

Maybe I got you wrong but in short
• all proposed solutions will display translated content but still redirect to the default (french) Log in Page.
(navigation and as consequence the language switcher is still displayed in french.)
• There does not exist any …..(get_permalink()); “stay on current page” option for s2members after login.

Unfortunately this does not really fit.

Anyway thank you very much for the effort.

In a sense, yes. BUT instead of it being your “French” Login Welcome Page, it will house ALL languages. So it will then just be your Login Welcome Page. Users will see content in a different language based on what you have set up here.

• There does not exist any …..(get_permalink()); “stay on current page” option for s2members after login.

If you’d like to do this with custom code, there is nothing stopping you here. You can redirect Users to a different page with PHP/JavaScript on your site if you’d like rather than this, but that’s not something supported directly by s2Member, and we cannot assist you with this as per our Support Policy.
