theme development - Change locale by detecting viewer's browser language setting and let them choose prefered language a

admin管理员组

文章数量:1122832

I am coming from a multi-linguo country, and viewers may speak different language.

I am writing a theme and I noticed that the language of my theme only changed based on the setting of my admin panel, which mean only logged-in user or admin can do so.

What if I wanted to do it automatically by detecting user browser preference? I am using Jquery to achieve some of this function but thinking it not the right way.

What I was doing is use jquery to set initial language by browser locale, and allow user to change it with press of a button, then save the setting to cookie.

I also tried using PHP to detect browser language, but what is the API to tell wordpress to show the correct language (e.g. screen-reader-text)? or allow a site visitor to change the language on-the-fly?

is there a "cleaner" way of doing it in wordpress using i18n on server side(while detecting browser setup and then letting viewers to change the language preference)?

• 1 you can use a plugin like polylang which install several languages in wordpress and detect the language the first time an user comes : wordpress.org/plugins/polylang – mmm Commented Jul 13, 2018 at 10:44
• Can I make manual translations to the menu items with this plugin? cuz I don't want some auto translate that might make weird translations. – adrian li Commented Jul 13, 2018 at 12:45
• Pretty amazing how little attention this question has gotten - seems like a very common need. – Isaac Lubow Commented Oct 9, 2019 at 19:16

You can get the browser language from the PHP global $_SERVER['HTTP_ACCEPT_LANGUAGE'] )
