Wow that is a lot of information and I hope that you can get this done.

When I created the class in APEX yesterday (messing around), I did notice that it does create a WSDL file.

I am not sure how you would access it with the Toolkit, but if there is another developer that has done this (as you have stated).

Do you know how to capture the Session Id from Salesforce?

Is it just a form that you have? Does this form insert to contacts, Cases, or both? IS it a lead that you are creating?

Sorry for all the questions....

Try and email Nick Tran at Salesforce, he is the one that wrote the PHPToolKit

I will PM his email addy to you

The NuSOAP wont work for this, it is too generic, The toolkit was written to replace that

ALSO

I don't/didn't know about the other class that you are using.

If I can get this figured out in the meantime, I will post it here

If you get it figured out, would you post your results here, it may help someone in the future
