PHP Concatenation not working with

Hi Ewout!
First of all, congratulations for your great plugin, a gret work!

I am facing, what I guess is an easy issue. I am not being able to get a string from the function: $wpo_wcpdf->get_custom_field( ‘inscription_textbox2’)

My code is:

function mycustom_headers_filter_function( $headers, $email ) {
global $wpo_wcpdf;

$email_address_to_send = $wpo_wcpdf->get_custom_field( ‘inscription_textbox2’);
$headers .= ‘BCC: ‘ . $email_address_to_send . “\r\n”;
return $headers;
}

The problem is that apparently the email string that comes from the textbox called ‘inscription_textbox2’ is not being concatenated in the headers variable …

I am sure that the email is being filled in the ‘inscription_textbox2’ text field since it is being correctly showed in the pdf.

Do you have any idea about how to solve it?

Thanks a lot in advance!
Angel.

Hello Angel,
The problem is that at the point where the headers filter is executed, the $order is not known yet to the PDF invoice plugin because the attachment is created later.
However, the latest version of WooCommerce has a third argument to the woocommerce_email_headers filter, which holds the $order object (or $user object for user emails, etc.). Note the ‘3’ in the add_filter arguments.
```
add_filter( 'woocommerce_email_headers', 'mycustom_headers_filter_function', 10, 3);
function mycustom_headers_filter_function( $headers, $email_id, $order ) {
    if ($email == 'customer_completed_order') {
        $email_address_to_send = get_post_meta( $order->id, 'inscription_textbox2', true );
        $headers .= 'BCC: ' . $email_address_to_send . "\r\n";
    }
 
    return $headers;
}
```
Important: you cannot globally apply this because for some emails (out of stock, user emails, etc.) there is not $order object available and this can throw errors.

Hope that helps!
Ewout

Hi Ewout!
Thanks a lot for your quick answer!
Actually this solution was intended only for sending the e-mail with the attached invoice to the correct e-mail address, so I guess that with the particularization you stated with $email == ‘customer_completed_order’ it should be OK to affect only this invoice attached mail, Am I right?

I will test it this evening!
Thanks again!

Hi Chilidogs,
That’s correct, only I made a small error in the code, $email should be $email_id:
```
add_filter( 'woocommerce_email_headers', 'mycustom_headers_filter_function', 10, 3);
function mycustom_headers_filter_function( $headers, $email_id, $order ) {
    if ($email_id == 'customer_completed_order') {
        $email_address_to_send = get_post_meta( $order->id, 'inscription_textbox2', true );
        $headers .= 'BCC: ' . $email_address_to_send . "\r\n";
    }
 
    return $headers;
}
```

Hi Ewout!

thanks a lot, the second version worked!

now What I am trying to do is to send the e-mail ONLY to the address in $email_address_to_send variable … I am trying to empty the variable $headers and afterwards to fill it with the $email_address_to_send but, I am still receiving the e-mail in the e-mail address of the user … I guess I am losing some details here … Any hint about it? Thanks a lot for your expert help!

Hi again Ewout!

For this second approach of changing the recipient of the mail it finally worked using the ‘woocommerce_email_recipient_’ filter as follows:
```
add_filter( 'woocommerce_email_recipient_customer_completed_order', 'your_email_recipient_filter_function', 10, 2);

function your_email_recipient_filter_function($recipient, $object) {
        $email_address_to_send = get_post_meta( $object->id, 'inscription_textbox2', true );
		if ( null == $email_address_to_send ){ 
	       return $recipient;
        }
        else{ 
             $recipient = null;
	     $recipient =  $email_address_to_send ;
             return $recipient;
	    }
}
```
Thanks a lot for your time and effort replying so quickly!
Best regards!
Angl.
