PDF generation not respectin current language

Hello Gaspar,
Unfortunately I cannot give support for mQtranslate.
If adding &lang=mynewlang to the url does not work then I’m afraid there’s not much I can do to help. You could try to change the urls in the plugin code in includes/class-wcpdf-writepanels.php. The urls for the order listing buttons are in the add_listing_actions function (line 86 and onwards).

However, this is not update proof and multilingual wordpress is quite complex. It will probably also not select the right language for emails (which is an internal process rather than a web call).

Note that we do support multilingual WordPress through WPML, if you use our Professional extension.

Kind regards,

What variable your plugin uses to detect which language file to include?

My plugin doesn’t use any variable: it just points WordPress to the location where all language files are stored, the rest is handled by WordPress, following your settings (or WPML if you’re using that).

Thanks. I’ve contacted to translation plugin developers to fix it.

One suggestion. Can you please add filter option for links (so other plugins can use them to add required parameters)? So we do not have to modify the core..

Hello Gaspar,
You can already do that, using the wpo_wcpdf_listing_actions filter!

for example:

add_filter( 'wpo_wcpdf_listing_actions', 'wpo_wcpdf_listing_actions', 10, 2 );
function wpo_wcpdf_listing_actions( $listing_actions, $order ) {
	$lang = 'mynewlang';
	$listing_actions['invoice']['url'] = wp_nonce_url( admin_url( 'admin-ajax.php?action=generate_wpo_wcpdf&template_type=invoice&order_ids=' . $order->id . '&lang='. $lang ), 'generate_wpo_wcpdf' ),
	return $listing_actions;
}

Well, thank you!
Excellent support ??

This filter ‘wpo_wcpdf_listing_actions’ is not valid for Account page.
It works in admin.

I used ‘wpo_wcpdf_myaccount_actions’ filter for that and it works.

Have a good day!
