How to convert array to xml and post to third party? - php

Question

I am having trouble converting an array into xml and then posting it to an third party URL as an xml post.
I believe i am close but i am missing something for it to work.
I am using wordpress and gravity form (I don't think it matters)
Here is what i have up-till now.
function post_to_third_party($entry, $form) {
$post_url = 'https://xxxx.com/home/BorrowerImport.do?CampaignID=xxx';
$body = array( 'firstname' => $entry['8.3'],
'lastname' => $entry['8.6'],
'dayphone' => $entry['12'],
'email' => $entry['11']
);
$xml = new SimpleXMLElement('<application/>');
$body = array_flip($body);
array_walk($body, array ($xml, 'addChild'));
print $xml->asXML();
$ch = curl_init($url);
//curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($ch);
echo $output;
curl_close($ch);
}
I also tried the following code this seems to work but the var_dump looks like string(201) " $firstname $lastname $dayphone $email " ok
I don't know how to populate the xml tags with the data gathered from the $body array
Here is the code i used for this result
add_action('gform_after_submission', 'post_to_third_party', 10, 2);
function post_to_third_party($entry, $form) {
$post_url = 'https://xxxx.com/home/BorrowerImport.do?CampaignID=xxx';
$body = array(
'firstname' => $entry['8.3'],
'lastname' => $entry['8.6'],
'dayphone' => $entry['12'],
'email' => $entry['11']
);
$xml = '
<?xml version="1.0" encoding="UTF-8"?>
<application>
<firstname>$firstname</firstname>
<lastname>$lastname</lastname>
<dayphone>$dayphone</dayphone>
<email>$email</email>
</application>';
var_dump($xml);
$ch = curl_init($url);
//curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($ch);
echo $output;
curl_close($ch);
}

Ok, here's the problem:
The method you are using to build the array before converting to XML is accidentally deleting some of the data.
You start out with something like this:
$body = array(
"firstname" => "Test",
"lastname" => "Test",
"dayphone" => "[phone]",
"email" => "test#gmail.com",
);
Then you call array_flip, which gives you this:
$body = array(
"Test" => "firstname",
"Test" => "lastname",
"[phone]" => "dayphone",
"test#gmail.com" => "email",
);
You now have two "Test" keys in your array. PHP keeps the last one an throws away the first. So your XML document is now missing one of the required keys: "firstname".
The solution is to build your XML document the old fashioned way and stay away from fancy stuff like array_flip:
foreach($body as $k=$v)
$xml->addChild($k, $v);
