Plugin footer

Hi @harutyun06,

The easiest way to add the shipping method to your footer is with our Premium templates extension. You can then simply use the {{shipping_method}} placeholder in the footer field.

You can achieve something similar with the following code snippet:

add_filter( 'wpo_wcpdf_footer_settings_text', 'wpo_wcpdf_add_shipping_method_to_footer', 10, 2 );
function wpo_wcpdf_add_shipping_method_to_footer( $text, $document ) {
	if ( $document->get_type() == 'invoice' ) {
		$text .= sprintf(' <p>%s</p>', $document->order->get_shipping_method() );
	}
	return $text;
}

This code snippet should be added to the functions.php of your child theme or via a plugin like Code Snippets. If you haven’t worked with code snippets or functions.php before please read this: How to use filters

This is working without any issues on my local environment. How did you add the filter to your site? Are you sure it is being called?
