Debugging faulty return $recipient;

Hi there!

First off, thank you for this plugin – great work!

I have an issue though, and the short question is: Can I get debug info about the returned value from the filter?

Long version of the question:
I’m trying to send a form to multiple recipients, but I can’t get it to work. I’ve figured out you can do this via commas, but it does not work with my filter.

This is what I’ve got:

/** Set the contact form 7 recipients with a filter.
 *  Separate multiple recipients with a comma (,).
 */
function wpcf7_dynamic_recipient_by_creator_mail($recipients, $args=array()) {

    $creators = get_field('product_creators');
    $recipients = '';
    $i = 0;
    foreach($creators as $creator) {
        $i++;
        $mail = get_field('creator_e-mail', $creator);
        $recipients .= $mail . ($i <= sizeof($creators)-1 ? ',' : '');
    }
    //expected:
    //return '1@abc.de,2@abc.de,3@abc.de';
    return $recipients;
}
add_filter('wpcf7_creator_recipients', 'wpcf7_dynamic_recipient_by_creator_mail', 10, 2);

The expected return is what I get when I echo the code on any given page, so the data retrieval part works. The dynamic recipient also works when I return the hard-coded value (and the mail gets sent to all recipients). But when I return the $recipient variable instead,I get a “your mail could not be sent, try later” error.

Now, my question is somewhere along the lines of: Can I get some debug info on what the return statement got? Because I can’t figure out why it does not work, because all single parts are working as they should.

Best Regards and thank you for your time,
Fabian
