Guzzle Post with arrays and strings

[jj]

When doing a Guzzle Post, If I pass a string the request, the response comes back correctly yet when I use a nested array it does not (I just get a 500 internal server error).

A shorthand version of what I am doing:

$client = new Guzzle\Http\Client();


$request = $client->post('http://foo.com',
	array(
		'Content-Type' => 'application/x-www-form-urlencoded',
		'Content-Length' => 'length'
	),array(
	'foo'=>'bar',
	'Data' => array(
		'LD'=> array(
			'ld1'=>1
		),
		'PD'=>array(
			'pd1'=>Input::get('pd1'),
			'pd2'=> Input::get('pd2'),
			'pd3'=>Input::get('pd3')
		),
		'CD'=>array(
			'cd1'=>Input::get('cd1'),
			'cd2'=>Input::get('cd2'),
			'cd3'=>Input::get('cd3')
	)
	));


When passing a string instead of an array to Data e.g:

<LD>
  <ld1>qwerty</ld1>
</LD>

<PD>
  <pd1>qwerty</pd1>
  <pd2>qwerty</pd2>
  <pd3>qwerty</pd3>
</PD>
<CD>
  <cd1>qwerty</cd1>
  <cd2>qwerty</cd2>
  <cd3>qwerty</cd3>
</CD>

The request works fine and returns the XML as expected.

I have no idea what i'm doing wrong. Hopefully someone with more experience can help.

The first request is sending POST data in the body, while the second is sending XML date. They are completely different requests and I'm not surprised that they get different results .

Thanks,

Michael

Thanks for your reply. 

Is it possible to pass a set of array key pairs so that Guzzle builds up the XML? I can't see anything in the docs about it but it would just be so much cleaner, rather than building up the string.

Any advise appreciated, thanks.

This is what Guzzle's service descriptions can be used for. They can marshal arrays to XML and XML to arrays.
