Undefined index: ebd_download and "Unexpected token N" AJAX error

  • Hi,

    just a notice to all:

    It just took me two hours to resolve the following bug

    Contact Form 7, Download Monitor and this plugin were working without any problems.

    But suddenly I got the following AJAX error after submitting the form:

    “Unexpected token N”

    Also the following PHP error appeared in the log files:

    Undefined index: ebd_downloads in /var/www/vhosts/teamact.de/httpdocs/wp-content/plugins/email-before-download/email-before-download.php on line 432

    The solutions was in my case very simple:

    I just deactivated WP_DEBUG in my wp-config.php

    define(‘WP_DEBUG’, false);

    This solved everything.

    I hope I will save someone two hours like me ??

    Cheers,
    dreamfish

  • In case someone is not comfortable with deactivating WP_DEBUG, I modified the email-before-download.php main file to correct the PHP notices that were interfering with AJAX:

    Around line 432, replace

    $dIds = $_POST['ebd_downloads'];

    with: 

    if (isset($_POST['ebd_downloads'])) {
      $dIds = $_POST['ebd_downloads'];
    } else {
      $dIds = FALSE;
    }

    That gets rid of the ebd_downloads notice. The other notice I’ve seen is that if you don’t have a your-name field in Contact Forms 7, it won’t work. It doesn’t need to be filled, but it needs to exist. You can probably do something similar to what I did with ebd_downloads, but since I didn’t have the time to look into what that variable was being used for in the plugin, I just added a hidden, empty your-name field in my form, and that was it. And that was only because I needed separated first and last name fields. If you don’t, just keep a field called your-name visible and that’s that.
