/**
 * Example QuickBooks SOAP Server / Web Service
 * 
 * This is an example Web Service which adds customers to QuickBooks desktop 
 * editions via the QuickBooks Web Connector. 
 * 
 * MAKE SURE YOU READ OUR QUICK-START GUIDE:
 * 	http://wiki.consolibyte.com/wiki/doku.php/quickbooks_integration_php_consolibyte_webconnector_quickstart
 * 	http://wiki.consolibyte.com/wiki/doku.php/quickbooks
 * 
 * You should copy this file and use this file as a reference for when you are 
 * creating your own Web Service to add, modify, query, or delete data from 
 * desktop versions of QuickBooks software. 
 * 
 * The basic idea behind this method of integration with QuickBooks desktop 
 * editions is to host this web service on your server and have the QuickBooks 
 * Web Connector connect to it and pass messages to QuickBooks. So, every time 
 * that an action occurs on your website which you wish to communicate to 
 * QuickBooks, you'll queue up a request (shown below, using the 
 * QuickBooks_Queue class). 
 * 
 * You'll write request handlers which generate qbXML requests for each type of 
 * action you queue up. Those qbXML requests will be passed by the Web 
 * Connector to QuickBooks, which will then process the requests and send back 
 * the responses. Your response handler will then process the response (you'll 
 * probably want to at least store the returned ListID or TxnID of anything you 
 * create within QuickBooks) and this pattern will continue until there are no 
 * more requests in the queue for QuickBooks to process.

	// Queueing up a test request

	//	
	//	Queue up a request to add a new customer to QuickBooks
	//	$Queue = new QuickBooks_Queue($dsn);
	//	$Queue->enqueue(QUICKBOOKS_ADD_CUSTOMER, $primary_key_of_new_customer);
	//	
	// Oh, and that new customer placed an order, so we want to create an 
	//	invoice for them in QuickBooks too: 
	// 
	//	Queue up a request to add a new invoice to QuickBooks
	//	$Queue->enqueue(QUICKBOOKS_ADD_INVOICE, $primary_key_of_new_order);
	// 
	// Remember that for each action type you queue up, you should have a 
	//	request and a response function registered by using the $map parameter 
	//	to the QuickBooks_Server class. The request function will accept a list 
	//	of parameters (one of them is $ID, which will be passed the value of 
	//	$primary_key_of_new_customer/order that you passed to the ->enqueue() 
	//	method and return a qbXML request. So, your request handler for adding 
	//	customers might do something like this: 
	// 
	//	$arr = mysql_fetch_array(mysql_query("SELECT * FROM my_customer_table WHERE ID = " . (int) $ID));
	//	// build the qbXML CustomerAddRq here
	//	return $qbxml;

	// 
	// NOTE: You would normally *never* want to do this in this file! This is 
	//	meant as an initial test ONLY. See example_web_connector_queueing.php for more 
	//	details!
	// 
	// IMPORTANT NOTE: This particular example of queueing something up will 
	//	only ever happen *once* when these scripts are first run/used. After 
	//	this initial test, you MUST do your queueing in another script. DO NOT 
	//	DO YOUR OWN QUEUEING IN THIS FILE! See 
	//	docs/example_web_connector_queueing.php for more details and examples 
	//	of queueing things up.

	// 	string $action				The type of action to queue up
	//	mixed $ident = null			Pass in the unique primary key of your record here, so you can pull the data from your application to build a qbXML request in your request handler
	//	$priority = 0				You can assign priorities to requests, higher priorities get run first
	//	$extra = null				Any extra data you want to pass to the request/response handler
	//	$user = null				If you're using multiple usernames, you can pass the username of the user to queue this up for here
	//	$qbxml = null				
	//	$replace = true				
	// 
	// Of particular importance and use is the $priority parameter. Say a new 
	//	customer is created and places an order on your website. You'll want to 
	//	send both the customer *and* the sales receipt to QuickBooks, but you 
	//	need to ensure that the customer is created *before* the sales receipt, 
	//	right? So, you'll queue up both requests, but you'll assign the 
	//	customer a higher priority to ensure that the customer is added before 
	//	the sales receipt. 
	// 
	//	Queue up the customer with a priority of 10
	// 	$Queue->enqueue(QUICKBOOKS_ADD_CUSTOMER, $primary_key_of_your_customer, 10);
