Hi @biedronjerzy,
thanks for your interest in this code! What you describe is the „default“ behavior of Translatepress without any modification involved, so this code here is not working for you. Now let‘s see why.
Can you please check if order_language is successfully stored with your test order? You should see it in the custom fields block of the order. Which value does it have?
the value is stored correctly. for orders in pl value is pl_PL
Okay! We should concentrate on one mail first and try to get this out in correct language. Let's take the "Your ... order #... has been cancelled" mail. In my WooCommerce Settings, there are two mails for this, one for the customer and one for myself, the site/shop administrator. Please be sure to look for the customers mail, because only that will be translated, not the one for the shop administrator.
First thing to check is if the locale gets correctly read from database and set for translatePress. Please set the subject for the customer's cancellation mail in WooCommerce Mail Settings to this value:
[trp_language language="pl_PL"]Polish[/trp_language][trp_language language="en_GB"]English[/trp_language]
Change the order status of the test customer's order to processing and to cancelled. Is the Subject of the customer's mail "Polish" or "English" (or empty)?
If it's "Polish", that means the translation by TranslatePress works, but native translation by .mo/.po-files doesn't. Next step is to check if the language files for polish are installed at all. You can switch the main language to polish, this should install any missing language files. Check the mails if they are now translated. Switch back the main language and check again if it works now.
problem solved.
after moving page to hosting there was no language pack for wocommerce. just english so it could not use pl templates because it wasn't there...
thanks for answet and helping with the problem :)
Hi, @dartrax thank you so much for putting together this code, it helped me a lot! :)
I'm a designer trying to cover everything, but I can only pretty much read PHP code and somewhat understand what it does.
Your code worked fine for the transaction emails but didn't work in case of reset passwords and new account emails. I believe this happened because the language in both cases is defined on other pages of the website rather than the Checkout. Is there any way I can tweak your code to also include these options or is it not possible?
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/).
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!
Hi,
First of all thanks for a great work :)
I've got some problem and i wonder if anyone had similar.
On locahost everything is working fine. But after moving to hosting i facing an issue.
My page is made in two languages main en_GB and second pl_PL. When someone is ordering in PL first mail is in PL. But all other emails send during order processing are in EN.
Maybe someone know what could be the problem?
