Notification Attachments for Multiple Forms

I have a client who, for his own reasons, wants multiple forms, each one sending a different document to the user who provides and email address. I found the gform_user_notification_attachments action and got that to work just fine for ALL form submissions, but obviously in this case, I need to send a different document depending on which form was submitted. So I modified the suggested code to switch the form ID - far more efficient and tidy than any other way - but for some reason it's not sending the document.

I do get the user notification. Yes. If I hard code one of the documents on the line that reads $attachments[] = $upload_path . $doc; for example, $attachments[] = $upload_path . "doc1.pdf"; then yes I will get that document, but as it stands below, it's not working. The only thing I can think of is that $form is in a format other than simple ID numbers?

add_filter("gform_user_notification_attachments", "add_attachment", 10, 3);
function add_attachment($attachments, $lead, $form) {

    switch($form) {
      case "1":
        $doc = "/2012/08/document_1_for_form_1.pdf";
        break;
      case "2":
        $doc = "/2012/08/document_2_for_form_2.pdf";
        break;
    }

    $upload = wp_upload_dir();
    $upload_path = $upload["basedir"];

    $attachments = array();
    $attachments[] = $upload_path . $doc;

    return $attachments;

}

When I switch the form ID, am I doing that right? I'm assuming that the function is receiving the form ID in the variable $form but maybe I've got the data format wrong?

Any help getting this working would be great. Thanks

Hi David, yes I originally had it set up without quotes but that didn't even send the email. I tried all three scenarios: no quotes, single quotes and double quotes. This was the result for each:

• no quotes = no email

• single quotes = no email

• double quotes = email but no attachment

Okay... I solved this... the problem *is* with the $form variable. It's not actually passing a literal form ID. It's passing an array. Either of my solutions above will work (for those interested) but instead of using $form in your comparison operations, you have to use $form['id'] like this:

if ( $form[ 'id' ] == 1 ) {
  $doc = '/2012/08/doc1.pdf';
}
