Sending xml to webservices using cURL

To give you an overview of what I’m trying to accomplish here, I am running a WordPress site with a custom theme and utilizing the Gravity Forms plugin to create all forms on the site.

We are integrating all (2) forms on the site with an external lead management service. Of course their documentation on how to interact with their webservice is far from well documented.

The provided PDF states:

It is assumed that the third-party vendor is familiar with creating XML files, understands XSD documents in order to create well-formed XML documents, and has the appropriate tools necessary to submit and receive XML documents via a webservice.

Webservice URL:

https://interface.webservices.popcard.ltsolutions.com/service.asmx

Webservice Method

InsertTraffic

InsertTraffic is a method a third-party vendor will use to insert a single piece of traffic into Yardi PopCard’ PopCard application. This single piece of traffic could represent a prospect filling out a contact form on an ILS website or a phone call received from a prospect which was answered by a call center. – Method description from PDF

I have been in contact with the company and know that the XML that I’m trying to push to their webservice is correct, but the leads are not getting into the system.

<?php 
add_action("gform_after_submission", "submit_contact_lead", 10, 2);

function submit_contact_lead($entry, $form){

  $fname = $entry['1.3'];
  $lname = $entry['1.6'];
  $userEmail = $entry['2'];
  if ($entry['3']) {
    $comments = $entry['3'];
  } else {
    $comments = '';
  }
  $date = date('Y-m-dTH:i');
  $baseURL = 'http://interface.webservices.popcard.ltsolutions.com/service.asmx/InsertTraffic';
  $xmlRequest = '<?xml version="1.0" encoding="utf-8"?>

    $xmlRequest = preg_replace( "/r|n/", "", $xmlRequest );

    // Set up cURL request directly in this funtion
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://interface.webservices.popcard.ltsolutions.com/service.asmx');
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml'));
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, "InsertTraffic=" . $xmlRequest);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); // set to 300 after testing purposes
    curl_setopt($ch, CURLOPT_TIMEOUT, 0); // set to 300 after testing purposes
    $result = curl_exec($ch);
    curl_close($ch);

    // $array_data = json_decode(json_encode(simplexml_load_string($data)), true);

    error_log('PopCards Submission | Contact/Reserve Submission for '.$lname.', '. $fname.'.');
    error_log($xmlRequest);
    error_log($result);
}

As you can see at the end of the code I’m logging the lead and the result. The following is what I’m getting in my error_log file.
