Intuit QuickBooks web connector IteratorID not valid error - quickbooks

Question

I have been trying to integrate a PHP based solution with QuickBooks Enterprise edition. I use QuickBooks PHP Dev Kit (http://consolibyte.com/quickbooks-open-source/) to connect the application to sync multiple modules bidirectionally.
The first module (QuickBooks to VtigerCRM) with multiple records are getting synced perfectly. When I try with my next module, only few records are getting synced and throws a error IteratorID is not valid. Then, I tried sending the params with new IteratorID in XML with no success.

Answer 1

So I see at least a few potential issues, and have some questions. First, some background --
Iterators in QuickBooks work just like a database cursor. Part of that means that you can't have two iterators open at once - you have to finish with one iterator before you start and/or continue another iterator. So if you do this, you'll get the error you're seeing:
Start iterator #1
Fetch some data from iterator #1
Start iterator #2
Try to fetch some data from iterator #1 again
That will fail because starting the second iterator has closed/killed the first iterator. This is probably what's happening to you.
What is this?
$extra['iteratorID'] = $saved_iterator_id; // From Table
That looks like an undefined variable to me. Did you check your PHP error logs?
Why are you saving this to a table, and what table are you saving it to? Where in the code are you pulling it back out of the table? I don't see any code that gets it from the table.
