Called deprecated function errors

Hi Andrés,

You can post an issue in the issue queue for Webform2PDF (at https://github.com/backdrop-contrib/webform2pdf/issues/) — although, since I'm the maintainer, I've now seen this and will have a bugfix release out very soon that addresses it!

The CiviCRM one is a bit harder to track down, because the civicrm.settings.php file is generated during installation and can be modified. Could you quote the lines around line 549 of civicrm.settings.php, so we can see what variable is being called?

Guessing that it's this (?):

if (!defined('CIVICRM_CLEANURL')) {
  if ( function_exists('variable_get') && variable_get('clean_url', '0') != '0') {
    define('CIVICRM_CLEANURL', 1 );
  }
  elseif ( function_exists('config_get') && config_get('system.core', 'clean_url') != 0) {
    define('CIVICRM_CLEANURL', 1 );
  }
  elseif( function_exists('get_option') && get_option('permalink_structure') != '' ) {
    define('CIVICRM_CLEANURL', 1 );
  }
  else {
    define('CIVICRM_CLEANURL', 0);
  }
}

There's a new release of Web2PDF that should address that part of the problem.

For the CiviCRM error, the conditional call to check the existence of variable_get is unnecessary because clean_url is in system.core from the outset in Backdrop. So you can just remove that check from your civicrm.settings.php file, i.e., change the code I quoted above to

if (!defined('CIVICRM_CLEANURL')) {
  if ( function_exists('config_get') && config_get('system.core', 'clean_url') != 0) {
    define('CIVICRM_CLEANURL', 1 );
  }
  elseif( function_exists('get_option') && get_option('permalink_structure') != '' ) {
    define('CIVICRM_CLEANURL', 1 );
  }
  else {
    define('CIVICRM_CLEANURL', 0);
  }
}

That looks like a new and different issue with the Webform2PDF module, and seems to be following logic that depends in part on the webform email settings.

Do you by any chance have the ability to use a debugger on this, and/or make test changes in a development environment, or is this a live/production site?

I can make a copy and test it in a development environment.

Let's do that, then. Please install and enable the Devel module, go to Permissions and give all roles "Access developer information" permission (ONLY on the dev site, of course!).

Then try replacing function webform2pdf_send2pdf() with this instrumented version and repeat the form submission that was causing the notice:

function webform2pdf_send2pdf($node, $submission) {
  $webform2pdf = _webform2pdf_get_template($node->nid);
  $nopdf = array();
  if (isset($webform2pdf['enabled']) && $webform2pdf['enabled'] && $webform2pdf['pdf_send_email']) {
    $no_mail = isset($webform2pdf['no_send_email_addr']) ? $webform2pdf['no_send_email_addr'] : FALSE;
dpm($no_mail,'$no_mail');
    if (is_array($no_mail)) {
      $no_mail = array_diff($no_mail, array(0));
      if ( !empty($no_mail) ) {
        foreach ($no_mail as $eid) {
          $email_addresses = $node->webform['emails'][$eid]['email'];
dpm($eid,'$eid');
dpm($email_addresses,'$email_addresses');
          if ( isset($node->webform['components'][$email_addresses]) ) {
            $email_addresses = $submission->data[$eid]['value'];
          }
          else {
            $email_addresses = array_filter(explode(',', check_plain($node->webform['emails'][$eid]['email'])));
          }
          $nopdf = array_merge($nopdf, $email_addresses);
dpm($nopdf,'$nopdf (1)');
          $nopdf = array_map("trim", $nopdf);
dpm($nopdf,'$nopdf (2)');
        }
      }
    }

    // Check for a multi-page form that is not yet complete.
    return array('nid' => $node->nid, 'sid' => $submission->sid, 'nopdf' => $nopdf);
  }
}
