Change the Invoice Date from Order Date to Date the order was completed.

Hi @gifiy,

Sorry your message slipped right through us!

I believe for this purpose, you could hide the Invoice date from the settings in the Document tab, then re-insert the “Completed Date: ” using the _date_completed meta-key. Somewhat following the examples here https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/displaying-a-custom-field/ to display Custom Fields in our PDFs.

Actually, there’s a better method that changes the invoice date itself, by using a filter:

add_filter( 'wpo_wcpdf_invoice_get_date', function( $date, $document ) {
	if ( $document->get_type() == 'invoice' && $order = $document->order ) {
		if ( $completed_date = $order->get_date_completed() ) {
			$date = $completed_date;
		} else { // fallback to order date
			$date = $order->get_date_created();
		}
	}
	return $date;
}, 10, 2 );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use filters

If you do prefer to print the “Completed date” as a separate date on the invoice, you should use the official WooCommerce method rather than calling it as a custom field, because technically it’s an order property (which is similar to custom fields, but behaves somewhat different):

// get formatted completed date (fallback to order date)
$completed_date = $order->get_date_completed() ? $order->get_date_completed()->format( wc_date_format() ) : $order->get_date_created()->format( wc_date_format() )

Hope that helps!

Perfect, it works like a masterpiece ??
I really appreciate your support!
