Change the word “Invoice”

Hi @jaweb1,

You will need to make following changes in woocommerce-delivery-notes.php file.

In the load(), add:

add_filter( 'wcdn_document_title', array( $this, 'wcdn_change_invoice_title' ), 10, 1 );

Here is the actual function if you were to rename ‘Invoice’ to ‘Tax Invoice’:

public function wcdn_change_invoice_title( $title ) {

	if ( 'Invoice' === $title ) {
		$title = 'Tax Invoice';
	}
	return $title;
}

Let me know if you have any other questions.

@joshuagawne,

When you say it removes all titles, do you mean to say it changes all titles to “Invoice”? Can you elaborate on the issue you are facing?
