Question

How to submit Infopath data to PHP WebService

Asked by: pixarksa

Hi, I am trying to design some form using Microsoft InfoPath. Then, I should create PHP WebService  to receive the submitted data.

I fall in a problem because i need to generate WSDL file for the webservice. I tried so many generators with no success. Finally, I created the same function in C# and got the .Net generated WSDL file. Still not working for php.

Infopath is very restricted with WSDL file format. I created a php client to call the service. that was working fine and easy. but Infopath is giving errors. I spent 3 days navigating internet for some hint or piece of idea with no progress.

I finally figured out that this topic has no reference on the web!

I will post all my code and i believe that the problem is in the WSDL file. I am expecting WSDL fix that works with InfoPath and client.php

Regards

{
	/**

	 *

	public function getMessage($data)
	{
		$h = mysql_connect('localhost', 'user', 'pass');
		mysql_select_db('dbname', $h);
		mysql_query("INSERT INTO infopath SET inf_text = '{$data}11'");
		return ' ';
	}
}
 
ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache
$server = new SoapServer("service.wsdl");
$server->setClass('Service');
$server->handle();

I've used this Webservice helper : http://www.jool.nl/new/1,webservice_helper.html

 

by: pixarksaPosted on 2009-06-16 at 03:47:12ID: 24636661

I already tried. It is not working with me. (I mean the helper, it is giving an error and not working). If you have a working copy of the application, i would appreciate if you can generate the WSDL from my service.php file posted earlier.

Thanks

OOI. You do realise that the getMessage() call is INSERTING data into a DB and returning nothing.

 

by: pixarksaPosted on 2009-06-16 at 05:38:39ID: 24637305

still not working. requiring Document/Literal instead of rpc/encoded

 

by: RQuadlingPosted on 2009-06-16 at 05:47:33ID: 24637357

Then I'm not sure. I use the SOAP Service helper a lot. I've got PHP and .NET consumers of the services.

I don't use InfoPath.

What errors/warnings/etc. do you get?

 

by: pixarksaPosted on 2009-06-16 at 23:16:05ID: 24645287

the error message is telling that infopath cannot work with rpc/encoded and it should be document/literal. WSDL helper might have some configurations to set that

 

by: RQuadlingPosted on 2009-06-17 at 00:42:51ID: 24645739

Just read about the differences. Of course there had to be more than 1 way to do something as simple as this. http://www.ibm.com/developerworks/webservices/library/ws-whichwsdl/

At this stage, I have to say I don't know how to achieve what you want from the SOAP helper.

You may have to simply build all the XML (WSDL, Requests, Responses) manually.

 

by: RQuadlingPosted on 2009-06-17 at 00:56:00ID: 24645803

Some links that may prove useful.

http://msdn.microsoft.com/en-us/library/ms996466.aspx#rpc_literal_topic3


But a comment on this PHP "bug" report (http://bugs.php.net/bug.php?id=30302), suggests that maybe PHP isn't going to do the do for you.

I've put a message to the PHP SOAP team. Hopeful for a response.

 

by: RQuadlingPosted on 2009-07-12 at 00:38:39ID: 24833551

I've not got a reply from the PHP-SOAP list. If the PHP SOAPServer class isn't/doesn't handle the document/literal style, then I think the only solution is to do all the logic manually. I don't think that would be an easy task.

I've got nothing more for this question at the moment. Sorry.

 

by: RQuadlingPosted on 2009-07-20 at 04:33:43ID: 24894023

There is a significant incompatibility between InfoPath and PHP's built-in SOAPServer class.

There is no simple solution.

Either the client must create compatible ouput for the server (I don't think this is possible as I suspect InfoPath is shrinkwrapped) or the server must adapt to the output from the client (distinctly possible, but a significant undertaking).

I don't think deleting this question is appropriate - the value here is the lack of compatibility between the two systems.

At least a PAQ with refund would be more appropriate.
