If amount of the order is 0, don't make invoice

Hi Prepu,
The last update included just what you need, a filter that determines whether an invoice is created/emailed or not.

add_filter( 'wpo_wcpdf_custom_email_condition', 'wpo_wcpdf_no_zero' , 10, 3 );

function wpo_wcpdf_no_zero( $condition, $order, $status ) {
	$order_total = get_post_meta($order->id,'_order_total',true);
	if ( $order_total > 0 ) {
		return true; // pdf is attached
	} else {
		return false; // no pdf
	}
}

Hi again Ewout,

I have added the code to my funtions.php and it works unless you press the “invoice” button in Woocommerce / Orders.

I have noticed that if I would like to have a look to the “invoice” it creates the invoice number. Perhaps it would be a good idea to disable the invoice button…

It is not an important issue.

Sorry for my bad english… ??

Yes, I’m assuming some intelligence from the shop manager. If the shop manager decides to create an invoice, then I’m not going to tell them they shouldn’t :o)

Everybody has very specific options, and this plugin would become a monster if I would integrate every single one of them in the core plugin. With filters like the one above and many others I already provide a lot of options for advanced customisation, but even that has a limit. I hope you understand!

That said, there are also options that are used a lot – like the invoice number formatting. I will probably make that a setting in the next release or the one after that.

Yes of course!

I know it is a silly (small) detail.

Your plugin is great!
