help with $modx->getChunk and XML syntax

I'm getting xml with a curl call to a remote server and would like to use the $modx->getChunk method to display results on a page, but can't get it to work.

here's the last few lines of the curl call:

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded"));
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

which outputs something like:

string(332) "<?xml version="1.0" encoding="UTF-8"?>
<xml>
<messages recipientcount="1">
<message>
<to>00000000</to>
<messageid>FB2FF641</messageid>
<errortext>Success</errortext>
</message>
</messages>
</xml>"

so I change the code to look something like this (and a number of different variations along these lines):

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded"));
$response = curl_exec($ch);
curl_close($ch);
$output = $modx->getChunk('test', array(
'messageid' => (string)$response -> messages -> message -> messageid
));
return $output;

In my testMessage chunk I want to have [[+messageid]] to display the messageid, but nothing is displayed

Seems like I just need to get the syntax right, but I can't find the solution. Any suggestions greatly appreciated.

Hi,
First of all why application/x-www-form-urlencoded instead application/xml?

Maybe this will help you:

$response = curl_exec($ch);
curl_close($ch);
$xml = simplexml_load_string($response);
foreach ($xml->messages as $message) {
//...do something
}

Thanks for you assistance himurovich.

It took me a while working on the '...do something' part but I came up with this working example:

 {
$to = ($messages->message->to);
$messageid = ($messages->message->messageid);
$errortext = ($messages->message->errortext);
$output .= $to.'<br>'.$messageid.'<br>'.$errortext;
}
return $output;

Still no joy getting it to work with a $modx->getChunk call. I tried a few variations of this:

{
$output .= $modx->getChunk('test', $messages);
}

then in my chunk:

[[+messages.message.to]]<br>
[[+messages.message.errortext]]<br>
[[+messages.message.messageid]]

but not getting any output. I can live with what I have and expand on the snippet, but it would be nice to do it via output modifiers from within the chunk. [ed. note: grogorio last edited this post 8 years, 1 month ago.]

BTW himurovich with regards to your question:

First of all why application/x-www-form-urlencoded instead application/xml?

I can't really give you a definitive answer as the curl connection script is supplied by the service provider. However if I use application/xml, the server responds with "Invalid credentials". [ed. note: grogorio last edited this post 8 years, 1 month ago.]

I found a solution here https://stackoverflow.com/questions/23991349/templating-a-snippet-with-modx-getchunk-returns-nothing

For my case, the following worked:

foreach ($xml->messages as $messages) {
$output .= $modx->getChunk('test', array(
'to' => (string)$messages->message->to,
'messageid' => (string)$messages->message->messageid,
'errortext' => (string)$messages->message->errortext
));
}

and in the chunk:

[[+to]]<br>
[[+errortext]]<br>
[[+messageid]]

hope it helps somebody (usually me when I've forgotten in a couple of years time how I did something) [ed. note: grogorio last edited this post 8 years, 1 month ago.]
