[Waiting for user feedback] Translate custom emails (plugin Order Status Manager for WooCommerce)

Can you please try the following?

1. Edit your `functions.php` file (preferably in a child theme) and add the following code:

// WPML Workaround
add_action( 'woocommerce_order_status_changed', 'switch_language_before_order_email', 5, 3 );
function switch_language_before_order_email( $order_id, $from, $to ) {

    if ( $to !== 'goods-ready' ) return;

    $order = wc_get_order( $order_id );
    $current_lang  = $order ? $order->get_meta( 'wpml_language', true ) : null;
    do_action( 'wpml_switch_language', $current_lang );

}

add_action( 'woocommerce_order_status_changed', 'restore_language_after_order_email', 20, 3 );
function restore_language_after_order_email( $order_id, $old_status, $new_status ) {
    if ( $new_status === 'goods-ready' ) {
        do_action( 'wpml_restore_language', null );
    }
}

2. Edit the plugin file at
wp-content/plugins/woocommerce-order-status-manager/src/class-wc-order-status-manager-order-status-email.php

Find this line:

return (string) apply_filters( "wc_order_status_manager_order_status_email_body_text_{$this->id}", $this->format_string( $this->body_text ), $this->object, $this );

Replace it with:

		$body_text = $this->body_text;
		if ( class_exists('Sitepress') ) { 
			do_action( 'wpml_register_single_string', 'woocommerce-order-status-manager', "Email {$this->id} - Body text", $body_text );
			$body_text = apply_filters( 'wpml_translate_single_string', $body_text, 'woocommerce-order-status-manager', "Email {$this->id} - Body text" );
		}
		return (string) apply_filters( "wc_order_status_manager_order_status_email_body_text_{$this->id}", $this->format_string( $body_text ), $this->object, $this );

3. Go to WooCommerce > Settings > Emails, open the relevant custom email, and re-save it.

4. Go to WPML > String Translation and search for the email body text under the text domain `woocommerce-order-status-manager`, then provide translations as needed.

5. To test the result, go to WooCommerce > Orders, and change the order status back and forth between “On hold” and “Goods Ready” to trigger the email notification.

6. Check your email logs to confirm if the translated version is being sent.

Does it work now?

Ok, let me know how it goes. As for the email notifications, I can see that emails are active for your account now, so I suppose you activated it within the top of this ticket, above the first reply?

Let me see with our compatibility developer if this is something that can be implemented perhaps through hooks, or if this is something coming from the WooCommerce Order Status Manager and can be only changed within their plugin.

I will keep you posted!

Hello there,

Our compatibility team confirmed that the emails received will be based on order language instead of user language settings.

Let me know if this helps.

Thanks

Hello there,

We don't have a deadline yet, I will update you once we receive confirmations from the compatibility team.

Thanks
