Translation with Polylang not working properly for some emails and PDFs

Hi there,

translating emails is a huge problem. By default, emails triggered by the admin will be sent in the language the admin has chosen within it’s profile. We’ve added explicit compatibility to translate emails using WPML. PolyLang does not natively support email translation for WooCommerce order emails. Maybe you should consider switching to PolyLang Pro (which I guess offers a Woo Plugin itself) to improve email translation. You might need to contact the support beforehand.

Cheers

Thank you for your reply. I contacted the support of the Polylang Pro plugin and they gave me the following answer:

Emails are sent through actions. And we need to hook Polylang to these actions to translate the email. So Polylang will translate emails only for known actions (the email itself doesn’t matter, only the action name). These actions are the ones used by WooCommerce. If this plugin sends emails upon an action unknown to Polylang, it won’t be translated. If this plugin use the WooCommerce actions so it will work. I recommend you to contact the plugin authors to check with them if they are using the same actions that use WooCommerce to send the emails.

Do the WGZD and WGZD Pro plugins only use WooCommerce actions or do they use their own?

Regarding the PDF emails it requires a specific compatibility to generate them in the correct language. … You should ask to the Germanized for WooCommerce Pro authors if they have already included a compatibility with Polylang for WooCommerce in order to translate the PDF.

As you already stated before, explicit compatibility to translate emails using WPML is given. Can you tell me if this compatibility is also given for PDFs?

So, I talked to the Polylang support team. They did some investigation work and came up with the following code, you might consider including in your next update:

add_action( 'pllwc_init', function() {
		$actions = array(
			// order shipped
			'woocommerce_gzd_shipment_status_draft_to_shipped_notification',
			'woocommerce_gzd_shipment_status_processing_to_shipped_notification',
			//order return
			'woocommerce_gzd_return_shipment_status_draft_to_processing_notification',
			'woocommerce_gzd_return_shipment_status_requested_to_processing_notification',
			//order return delivered
			'woocommerce_gzd_return_shipment_status_processing_to_delivered_notification',
			'woocommerce_gzd_return_shipment_status_shipped_to_delivered_notification',	
		);

		foreach ( $actions as $action ) {
			add_action( $action, function( $shipment_id ) {
				$shipment = wc_gzd_get_shipment( $shipment_id );
				PLLWC()->emails->before_order_email( $shipment->get_order() );
			}, 1 ); // Switch the language for the email
			
			add_action( $action, array( PLLWC()->emails, 'after_email' ), 999 ); // Switch the language back after the email has been sent
		}
} );

However, they couldn’t figure out how the “customer invoice cancellation” email is triggered. Can you please tell me how this is done or contact the Polylang support directly at [email protected].

Thanks

Hi there,

the invoice cancellation email is being sent as soon as it was generated and/or the shop administrator used the “send button” to send the invoice to the customer. The woocommerce_gzd_switch_email_locale hook might be used to change the email language of any email sent by Germanized.

Cheers
