woocommerce_email_attachments hook with empty $order argument in Woocommerce

The person building a WP site for me is stuck for some time now with this problem. He needs to attach some custom PDF files into the order confirmation mail. He uses woocommerce_emails_attach_downloadables function to do that. For some reason that function is getting called with the $order parameter being empty.

Here is the code he uses :

add_filter( 'woocommerce_email_attachments', 'attach_order_notice', 10, 3 );
function attach_order_notice ( $attachments, $email_id, $order )


//

 // Only for "New Order" email notification (for admin)
 if( $email_id == 'customer_on_hold_order' )

 $pdf_options = array(
// "source_type" => 'html',
// "source" => '<html>hello</html>',
 "source_type" => 'url',
 "source" => 'http://tag4u.devurl.co.il/checkout/order-received/757/?key=wc_order_5bce0e5ba39b8',
 "action" => 'save',
 "save_directory" => get_template_directory() .'/pdfs',
 "file_name" => 'print-pdf'. json_encode($order) .'.pdf');


// phptopdf($pdf_options);




 $attachments = get_template_directory() . '/pdfs/print-pdf.pdf';
 
 return $attachments;

So my questions are:

What are those cases ?

What can cause $order to be passed as empty ?

Your developer has been using maybe this woocommerce official snippet (That is outdated as it is 3 years old) and it uses woocommerce_email_attachments filter hook.

This filter hook is defined:

one time (1) in WC_Email class (with the $order argument)

three times (3) in WC_emails Class (without the $order argument)

So the WC_Order Object $order is only defined in WC_Email class as third argument.

That means that this outdated official code need to be tweaked as follow:

add_filter( 'woocommerce_email_attachments', 'woocommerce_emails_attach_downloadables', 10, 3 );
function woocommerce_emails_attach_downloadables( $attachments, $email_id, $order ) ! isset( $email_id ) ) 
 return $attachments;
 

 // ===> Your custom code goes Here <===

 return $attachments;

This should work avoiding problems.

So as you are asking, this hook is also used on the following specific product notifications with really different hook arguments:

On "Low stock" notification (with 'low_stock' and $product as 2nd & 3rd arguments)

On "No stock" notification (with 'no_stock' and $product as 2nd & 3rd arguments)

On "Backorder" notification (with 'backorder' and $args as 2nd & 3rd arguments)

So here the 2nd argument is the stock status $stock_status and the 3rd argument is the WC_Product object $product (or an array $args).

Then In those 3 notifications, the $order object doesn't exist as it can be a WC_Product Object, an array, an empty array, or null.

thanks ! I think the answer is very close to what you said. I updated the original question with the real code. Could you see what is wrong there ? I see that he uses a different filter than the one mentioned
– Louis Shraga
Nov 12 at 13:16

Just to better understand the answer : the same hook is called a number of times for the same order ? Some of the times with a set A of params and the other times with a somewhat different set of params ? And in the hook the code needs to "understand" which type of a call this one is ? Right ?

@LouisShraga The hook is called on other notifications as product Low stock, No stock, Backorder… And it's called on all Order notifications, if you don't restrict it to a specific $email_id. In your code it's restricted to $email_id = 'customer_on_hold_order' so it's used on Customer on Hold Order email notification… If you like/want you could please also upvote this answer. Thank you anyway.

Thanks, do you know and/or can point me please to the documentation (i just cant find it) where it says if $order is set for a call in case of customer_on_hold emailId

@LouisShraga There is no a specific documentation… When an order is set ta a specific order status, it will trigger the related email notification, if it's set and defined… You can explore the source code of each woocommerce classes starting with WC_Email For each class you have the order status transitions that is triggering an email.
