Thanks for writing this code! I just implemented it on my site and it works smoothly.
Hi,
I'm Razvan, developer at TranslatePress. We implemented this feature in TranslatePress - Multilingual plugin and it's available in the latest free version.
Check out the documentation on it.
Thanks to everyone that contributed to this custom code and thread. It helped our development team implement the feature.
For the projects that already have this custom code, it should be safe to remove it and update TranslatePress. For orders already placed that were not yet marked as finished, default language will be used in emails. You can change wp_postmeta meta_key order_language to trp_language in order for the current unfinished orders to have further emails sent in the checkout language.
Best regards,
Razvan
Hi @razvan-translatepress,
thanks for your reply - it is very nice that you showed up here to say thank you 👍 I'm glad that the code helped to implement this important feature. I've not updated TranslatePress yet, but I certainly will and test this!
Your explanation on how to migrate is also very appreciated.
Are there any restrictions regarding the minimum WooCommerce Version supporting this feature? I've read that you needed WooCommerce to implement some changes in their code in order to make this work somewhere else - is this still true?
As written in the documentation I linked earlier, these are the version requirements:
TranslatePress - Multilingual, version 2.3.5+
WooCommerce, version 6.8+
Hello everyone. Is this work with Polylang for WooCommerce? I am asking because my shop have two languages: main Polish and second English. When customer order by choosing eng language the first e-mail is translated perfectly, but others like invocie or order aren’t.
Hi @mystertaran,
thanks for the question!
It is only for Translatepress - however, this is obsolete now, as Translatepress has this function built in since version 2.3.5!
I do have the last version, still same issue, first order email in user's language, shipping statue emails are sent in the website default language.
Any clear instruction on how did you get it to work?
Hi @medchehida,
do you use Translatepress? The newer versions do have this feature already built in.
@dartrax Yes i'm using Translatepress, the latest version
Tried your shortcode same issue.
The only way i found is to use Yaymail premium, but i'm looking for a free alternative.
Translatepress should do this natively since version 2.3.5 - please ask the Translatepress team for support in this matter!
Hi @natachao,
Password reset and new account mails should work out of the box with Translatepress, my Code here isn't needed for that. Are you sure you have the language packs installed for the languages you use? If you want to customize the mail's content, you could use conditional shortcodes (see https://wordpress.org/support/topic/multi-language-emails-3/).
