I'm making my first attempt to connect to a SOAP server from PHP, and I'm not understanding how to log in and get the data I need. The service I'm trying to connect to is the Hawley USA service http://hawleyusa.com/thcServices/StoreServices.asmx). I've been looking at a few posts on how to connect, and I get the basics. I've verified that I have SOAP enabled in my PHP, and I'm just trying to get an inventory list. Here's the code I'm using:

<?php ini_set("soap.wsdl_cache_enabled", "0"); // disabling WSDL cache $wsdl_path = "http://hawleyusa.com/thcServices/StoreServices.asmx?WSDL"; $login_id = 'mylogin_id'; $password = 'mypassword'; $client = new SoapClient($wsdl_path); try { echo "<pre>\n"; print($client->InventoryList(array("LoginID" => $login_id, "Password" => $password))); echo "\n"; } catch (SoapFault $exception) { echo $exception; }

However, when I run this code, I get this error:

SoapFault exception: [soap:Server] Server was unable to process request. ---> Object reference not set to an instance of an object. in /Users/steve/Sites/mysite/hawley_client.php:12

When debugging, I can see the $client instance initiated, so I'm not sure why I'm getting this error.

Second question: Am I passing the user ID and password correctly?

Thanks.

Update: I threw in $client->__getLastRequest, and this is what I got:

<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://hawleyusa.com/thcServices/"> <SOAP-ENV:Body> <ns1:InventoryList/> </SOAP-ENV:Body> </SOAP-ENV:Envelope>

So I can see that I'm missing my login ID and password. How do I add them to my InventoryList call?

    As of 2017/06/09, the WSDL is not available and the question is incomplete... Commented Jun 9, 2017 at 19:21
  • "Object reference not set to an instance of an object." typically means a parameter is wrong/missing in the SOAP-request. Be sure to check not only the <soapenv:body> but also the <soapenv:header> (this was the problem in my case). Commented Feb 24, 2020 at 9:36

You're close. Looking at the WSDL the InventoryList method takes an object called "request". Modify your call line slightly:

$client->InventoryList(array("request" => array("LoginId" => $login_id, "Password" => $password));

Hmm, I tried that before, but I must have done something wrong. Anyway, that gets me closer, but now I get this error: Catchable fatal error: Object of class stdClass could not be converted to string in /Users/steve/Sites/mysite/hawley_client.php on line 15 Line 15 is this line, BTW. Looking at the headers, the info is being sent properly now.
Major facepalm here: I was using print() with an object. Changed to var_dump, and it works. Thanks.

Probably it's not the same case but it also gives the same error if you don't specify empty strings in fields you don't need to use, taken from http://www.sitepoint.com/forums/showthread.php?755549-SOAP-XML-Object-reference-not-set-to-an-instance-of-an-object

In my case this was the error. I had to provide an empty string on optional fields.
0

I my case the problem was in typo:

In given docs the filed name was documentShipmentAddress (and I was using this)

but in wdsl (schema) was:

shipmentAddress

So that could be the problem with this error message. I have changed the field name to shipmentAddress and it solved the problem.
