Thanks for the quick answer! I have just added “Vendidero\StoreaBill\Invoice\Invoice” to the code and it worked as expected! The invoice notification email was sent in the language that the customer ordered.

Are there any additional objects besides shipping object (“Vendidero\Germanized\Shipments\Shipment“) and invoice object (“Vendidero\StoreaBill\Invoice\Invoice“) I should consider on my code?

Also, is there any method you recommend me to use to check whether Germanized plugin is activated? I am currently using: if (class_exists('Vendidero\Germanized\Packages').

Thanks!

Hi Dennis,

Thank you for your reply. I investigated it further and was able to partially solve the problem.

I get the language in which the order was placed in Polylang ($order_language = pll_get_post_language($order->get_id(), 'slug')) and then I temporary switch the locale (switch_to_locale($order_locale)) so that the email is send in the correct language. It works when I manually click to submit the email.

Unfortunately it’s not working when I submit the invoice to the client (and I expect that it will also not work when I send the order shipped notification to the client – but this was yet not tested).

Maybe Germanized uses custom hooks or methods for sending emails? Could you support me here?

Thanks!

// To prevent issues where simultaneous purchases by different users in different languages might result in email notifications being sent in the wrong language, the code avoids using global variables. Instead, it handles locale switching in an isolated manner for each request.

Hi Dennis,

Thank your for your answer.

It would be great to have Polylang support in the future.

In the meantime, is there a way to find/change the language of the emails? Polylang has a documentation on how to translate strings (as described here). I did not find the words stated in the “Order shipped” and “Invoice (PDF)” email notification, like:

“Your order on XXXX has been shipped via DHL. Find details below for your reference”
“Invoice 2024 XXXX has been attached to this email. Find details below for your reference”

My questions:
– Are these templates coming from Germanized? If yes, where are they located (path)?
– Can I force the template to be send out in German? Given the lack of support to Polylang, I would prefer to send all these emails in German.

Thanks and kind regards

Thanks @rickdebilt for the update.

It’s unfortunate that Elementor hasn’t implemented this feature yet. It will most likely take a long time before they do, if at all.

Thanks!

Hi @antoiub, thanks for your response. Given that I am not able to edit the main thread and avoiding creating a new one with the exact same issue, I have activated a temporary URL. The URL will expire in 10 hours: https://www.temporary-url.com/0B280D
