Quickbook web connector not sending new customer to my website - quickbooks

I want to exchange data(customer,invoice,order etc) between Quickbook Desktop and my website using REST API . I am using quickbook web connector and Consolibyte PHP SDK (https://github.com/consolibyte/quickbooks-php) for this purpose. I have installed web connector and configured PHP SDK also load example.qwc in web connector with my configuration.
Now I am able to create new customer to Quickbook Desktop when new customer is added to my website using this file and folder of PHP SDK(quickbooks-php/docs/web_connector). This is working fine Now I am looking for whenever new record(customer,invoice etc) is created on Quickbook Desktop that should be created on my website.How can I send this data to my website
Issues:
Is web connector automatically maintain two way communication or I need to write some PHP Soap web services code to read data from quickbook desktop.
How I know new customer,invoice, order is created on Quick book Desktop.and then how can I send this new data to my website.

1.Is web connector automatically maintain two way communication
The Web Connector does not automatically do ANYTHING.
Anything you want to happen, you need to write code for. The SDK handles a lot of the hard protocol stuff for you, but you still need to write some code.
2.How I know new customer,invoice, order is created on Quick book Desktop
You need to query QuickBooks for that data. There are examples that show you how to do this:
https://github.com/consolibyte/quickbooks-php/blob/master/docs/web_connector/example_web_connector_import.php
Basically, you're going to:
1. Add something new to your $map variable:
`QUICKBOOKS_IMPORT_INVOICE => array( '_quickbooks_invoice_import_request', '_quickbooks_invoice_import_response' ),`
2. Write those two new functions that the $map variable references.
The request function is going to return a qbXML request to query for new invoices, and the response function is going to handle the big list of new invoices that QuickBooks returns to you (in the example below, it stores them in a MySQL database):
/**
* Build a request to import invoices already in QuickBooks into our application
*/
function _quickbooks_invoice_import_request($requestID, $user, $action, $ID, $extra, &$err, $last_action_time, $last_actionident_time, $version, $locale)
{
// Iterator support (break the result set into small chunks)
$attr_iteratorID = '';
$attr_iterator = ' iterator="Start" ';
if (empty($extra['iteratorID']))
{
// This is the first request in a new batch
$last = _quickbooks_get_last_run($user, $action);
_quickbooks_set_last_run($user, $action); // Update the last run time to NOW()
// Set the current run to $last
_quickbooks_set_current_run($user, $action, $last);
}
else
{
// This is a continuation of a batch
$attr_iteratorID = ' iteratorID="' . $extra['iteratorID'] . '" ';
$attr_iterator = ' iterator="Continue" ';
$last = _quickbooks_get_current_run($user, $action);
}
// Build the request
$xml = '<?xml version="1.0" encoding="utf-8"?>
<?qbxml version="' . $version . '"?>

return $xml;
}
/**

*/
function _quickbooks_invoice_import_response($requestID, $user, $action, $ID, $extra, &$err, $last_action_time, $last_actionident_time, $xml, $idents)
{
if (!empty($idents['iteratorRemainingCount']))
{
// Queue up another request
$Queue = QuickBooks_WebConnector_Queue_Singleton::getInstance();
$Queue->enqueue(QUICKBOOKS_IMPORT_INVOICE, null, QB_PRIORITY_INVOICE, array( 'iteratorID' => $idents['iteratorID'] ));
}
// This piece of the response from QuickBooks is now stored in $xml. You
// can process the qbXML response in $xml in any way you like. Save it to
// a file, stuff it in a database, parse it and stuff the records in a
// database, etc. etc. etc.
//
// The following example shows how to use the built-in XML parser to parse
// the response and stuff it into a database.
// Import all of the records
$errnum = 0;
$errmsg = '';
$Parser = new QuickBooks_XML_Parser($xml);
if ($Doc = $Parser->parse($errnum, $errmsg))
{
$Root = $Doc->getRoot();
$List = $Root->getChildAt('QBXML/QBXMLMsgsRs/InvoiceQueryRs');
foreach ($List->children() as $Invoice)
{

);
QuickBooks_Utilities::log(QB_QUICKBOOKS_DSN, 'Importing invoice #' . $arr['RefNumber'] . ': ' . print_r($arr, true));
foreach ($arr as $key => $value)
{
$arr[$key] = mysql_real_escape_string($value);
}
// Store the invoices in MySQL
mysql_query("
REPLACE INTO
qb_example_invoice
(
" . implode(", ", array_keys($arr)) . "
) VALUES (
'" . implode("', '", array_values($arr)) . "'
)") or die(trigger_error(mysql_error()));
// Remove any old line items
mysql_query("DELETE FROM qb_example_invoice_lineitem WHERE TxnID = '" . mysql_real_escape_string($arr['TxnID']) . "' ") or die(trigger_error(mysql_error()));
// Process the line items
foreach ($Invoice->children() as $Child)
{
if ($Child->name() == 'InvoiceLineRet')
{
$InvoiceLine = $Child;
$lineitem = array(
'TxnID' => $arr['TxnID'],
'TxnLineID' => $InvoiceLine->getChildDataAt('InvoiceLineRet TxnLineID'),
'Item_ListID' => $InvoiceLine->getChildDataAt('InvoiceLineRet ItemRef ListID'),
'Item_FullName' => $InvoiceLine->getChildDataAt('InvoiceLineRet ItemRef FullName'),
'Descrip' => $InvoiceLine->getChildDataAt('InvoiceLineRet Desc'),
'Quantity' => $InvoiceLine->getChildDataAt('InvoiceLineRet Quantity'),
'Rate' => $InvoiceLine->getChildDataAt('InvoiceLineRet Rate'),
);
foreach ($lineitem as $key => $value)
{
$lineitem[$key] = mysql_real_escape_string($value);
}
// Store the lineitems in MySQL
mysql_query("
INSERT INTO
qb_example_invoice_lineitem
(
" . implode(", ", array_keys($lineitem)) . "
) VALUES (
'" . implode("', '", array_values($lineitem)) . "'
) ") or die(trigger_error(mysql_error()));
}
}
}
}
return true;
}
3. Make sure that every time the Web Connector connects, you automatically send it that query to get those new invoices.
Register a hook like this:
// An array of callback hooks
$hooks = array(
QuickBooks_WebConnector_Handlers::HOOK_LOGINSUCCESS => '_quickbooks_hook_loginsuccess', // call this whenever a successful login occurs
);
That always queues up a request to get invoices:
function _quickbooks_hook_loginsuccess($requestID, $user, $hook, &$err, $hook_data, $callback_config)
{
$Queue->enqueue(QUICKBOOKS_IMPORT_INVOICE, 1, QB_PRIORITY_INVOICE);
}
You'll want to make sure to look at the example I linked above for a few of the helper functions if you're going to re-use the code I pasted above.
If you have trouble, please POST YOUR CODE so we can see what you're tried so far.

force download using ZF2

I am trying to do force download using ZF2. Here is the snippet to my code
use Zend\Http\Request;
.....
public function downloadAction() {
$response = new Request();
$response->setHeaders(Request::fromString("Content-Type: application/octet-stream\r\nContent-Length: 9\r\nContent-Disposition: attachment; filename=\"ultimate_remedy_readme.txt\""));
}
now i am getting this error
/var/www/whowantsmymoney/vendor/zendframework/zendframework/library/Zend/Http/Request.php:88
Message:
A valid request line was not found in the provided string
Stack trace:
#0 /var/www/whowantsmymoney/module/Admin/src/Admin/Controller/LanguageController.php(93): Zend\Http\Request::fromString('Content-Type: a...')
This code should help you for a simple file download.
public function downloadAction() {
$fileName = 'somefile';
if(!is_file($fileName)) {
//do something
}
$fileContents = file_get_contents($fileName);
$response = $this->getResponse();
$response->setContent($fileContents);
$headers = $response->getHeaders();
$headers->clearHeaders()
->addHeaderLine('Content-Type', 'whatever your content type is')
->addHeaderLine('Content-Disposition', 'attachment; filename="' . $fileName . '"')
->addHeaderLine('Content-Length', strlen($fileContents));
return $this->response;
}
I imagine this code leaves a lot to be desired, but should work in simple cases, as was mine. I'm not sure how you might handle reading the file in chunks. Maybe somebody else could shed some light?
Edit - Sending streams
I've added this here for informational purposes. It is probably the better way to force downloads as it will use much less memory.
public function downloadAction() {
$fileName = 'somefile';
$response = new \Zend\Http\Response\Stream();
$response->setStream(fopen($fileName, 'r'));
$response->setStatusCode(200);
$headers = new \Zend\Http\Headers();
$headers->addHeaderLine('Content-Type', 'whatever your content type is')
->addHeaderLine('Content-Disposition', 'attachment; filename="' . $fileName . '"')
->addHeaderLine('Content-Length', filesize($fileName));
$response->setHeaders($headers);
return $response;
Thanks to #Aydin Hassan for response, but several important headers are missing in his answer. Be careful of that.
Full headers stack:
public function downloadAction() {
$file = 'path/to/file';
$response = new \Zend\Http\Response\Stream();
$response->setStream(fopen($file, 'r'));
$response->setStatusCode(200);
$response->setStreamName(basename($file));
$headers = new \Zend\Http\Headers();
$headers->addHeaders(array(
'Content-Disposition' => 'attachment; filename="' . basename($file) .'"',
'Content-Type' => 'application/octet-stream',
'Content-Length' => filesize($file),
'Expires' => '#0', // #0, because zf2 parses date as string to \DateTime() object
'Cache-Control' => 'must-revalidate',
'Pragma' => 'public'
));
$response->setHeaders($headers);
return $response;
}

How do I get a LinkedIn request token?

Hey I'm trying to use LinkedIn's OAuth in PHP. I'm stuck at the first step of getting a request token. All I know is you post some values to their server and get your token back. So i post the documented args to 'https://api.linkedin.com/uas/oauth/requestToken' and I get slapped with a 400 error.
here's the request:
$postArr = array();
//$postArr["oauth_callback"] = ""; idk they said this was optional...
$postArr["oauth_consumer_key"] = "ForBritishEyesOnly"; //is this the application secret key or the api key?
$postArr["oauth_nonce"] = "UltraRandomNonceFTW";
$postArr["oauth_timestamp"] = time();
$postArr["oauth_signature_method"] = "HMAC-SHA1"; //lolwut
$postArr["oauth_version"] = "1.0";
$params = array('http'=>array('method'=>'post','content'=>http_build_query($postArr)));
$context = stream_context_create($params);
$stream = file_get_contents('https://api.linkedin.com/uas/oauth/requestToken', false, $context);
I don't think my POST args are correct but ANY help is very appreciated -- I just don't want resort to use someone else's library to solve this.
-------EDIT: ATTEMPT 2 per James' input ---------
ok so here im making a call to the test link you sent me. i'm actually able to get a response back, but it doesnt like my signature (big surprise, i know). So just how bad did I screw up the encryption?
//setup GET args
$url = "http://term.ie/oauth/example/request_token.php?";
$url .= "oauth_version=1.0&";
$url .= "oauth_nonce=" . rand(0, 100000) . "&";
$url .= "oauth_timestamp=" . time() . "&";
$url .= "oauth_consumer_key=key&";
$url .= "oauth_signature_method=HMAC-SHA1&";
//encrypt the request according to 'secret'
$sig = urlencode(base64_encode(hash_hmac("sha1", $url, "secret")));
//append the url encoded signature as the final GET arg
$url .= "oauth_signature=" . $sig;
//do it to it
echo file_get_contents($url);
EDIT by James
Try:
//setup GET args
$url = "http://term.ie/oauth/example/request_token.php?";
$url .= "oauth_consumer_key=key&";
$url .= "oauth_nonce=" . rand(0, 100000) . "&";
$url .= "oauth_signature_method=HMAC-SHA1&";
$url .= "oauth_timestamp=" . time() . "&";
$url .= "oauth_version=1.0&";
I'm on cloud nine. Decided to revisit this problem and got it to work. Here is some very bare bones PHP to build a token request for LinkedIn (it outputs an anchor tag)
<?php
$endpoint = "https://api.linkedin.com/uas/oauth/requestToken";
$key = "YourAPIKey";
$secret = "YourAPISecret";
$params = array(
"oauth_version" => "1.0",
"oauth_nonce" => time(),
"oauth_timestamp" => time(),
"oauth_consumer_key" => $key,
"oauth_signature_method" => "HMAC-SHA1"
);
function SortedArgumentString($inKV)
{
uksort($inKV, 'strcmp');
foreach ($inKV as $k => $v)
$argument[] = $k."=".$v;
return implode('&', $argument);
}
$baseString = "GET&" . urlencode($endpoint) . "&" . urlencode(SortedArgumentString($params));
$params['oauth_signature'] = urlencode(base64_encode(hash_hmac('sha1', $baseString, $secret."&", TRUE)));
echo "<a href=\"" . $endpoint . "?" . SortedArgumentString($params) . "\">Get Token<a/><br/>";
?>
oauth_consumer_key is a value that LinkedIn should have assigned to your app. Did you register with them?
oauth_nonce should be different for each request to prevent replay-attacks.
If you're using HMAC-SHA1 you'll need to add the oauth_signature field yourself. Creating the signature manually is a total PITA.
There's also a lot of Base64 encoding to do (with the added bonus of some special OAuth quirks). I suggest you read the spec.
There is a test server and client at this link. It's quite useful when you're struggling to get the protocol right.

Using basic oauth to send a tweet

I was using basic auth to send tweets from a server every time a song changed. Now they have blocked basic auth and I am not sure how to incorporate it. I have a server at home that updates an html file on the webserver and then calls the following script to tweet out from that file. Any ideas on how to accomplish this simply?
<?php

$password = '#####';
DEFINE(htmlfile, '/homec/public_html/site.com/twitter.html');
$stationURL = "http://www.site.com";
$maxLimit = "139";
$da="";
$f=#fopen(htmlfile, "r");
if ($f!=0)
{
$da=#fread($f, 4096);
fclose($f);
}
else
{
exit;
}
$da=str_replace("\r", "\n", $da);
$da=str_replace("\n\n", "\n", $da);
$d=explode("\n", $da);
$d[0]=trim($d[0], "|"); // title

//====================================================
if ($d[0]=="" || $d[1]=="")
{
// IF WE COULD NOT GRAB THE ARTIST AND
// SONG TITLE FROM THE SAM-GENERATED HTML FILE,
// WE'LL BAIL OUT NOW WITHOUT SUBMITTING ANY TEXT

exit;
}
else
{
// SUCCESS IN GETTING ARTIST AND TITLE!

Download the latest version of TwitterOAuth from http://github.com/abraham/twitteroauth/downloads Unpack the download and place the twitteroauth.php and OAuth.php files in the same directory as a file with the following code. Register an application at http://dev.twitter.com/apps and from your new apps details page click on "my access token" to get your access token. Fill the four required variables into the script below and you can then run it to post new tweets.
<?php
require_once('twitteroauth.php');
$connection = new TwitterOAuth('app consumer key', 'app consumer secret', 'my access token', 'my access token secret');
$connection->post('statuses/update', array('status' => 'text to be tweeted'));

How do you POST to a page using the PHP header() function?

I found the following code on here that I think does what I want, but it doesn't work:
$host = "www.example.com";
$path = "/path/to/script.php";
$data = "data1=value1&data2=value2";
$data = urlencode($data);
header("POST $path HTTP/1.1\r\n");
header("Host: $host\r\n");
header("Content-type: application/x-www-form-urlencoded\r\n");
header("Content-length: " . strlen($data) . "\r\n");
header("Connection: close\r\n\r\n");
header($data);
I'm looking to post form data without sending users to a middle page and then using JavaScript to redirect them. I also don't want to use GET so it isn't as easy to use the back button.
Is there something wrong with this code? Or is there a better method?
Edit I was thinking of what the header function would do. I was thinking I could get the browser to post back to the server with the data, but this isn't what it's meant to do. Instead, I found a way in my code to avoid the need for a post at all (not breaking and just continuing onto the next case within the switch).
The header function is used to send HTTP response headers back to the user (i.e. you cannot use it to create request headers.
May I ask why are you doing this? Why simulate a POST request when you can just right there and then act on the data someway? I'm assuming of course script.php resides on your server.
To create a POST request, open a up a TCP connection to the host using fsockopen(), then use fwrite() on the handler returned from fsockopen() with the same values you used in the header functions in the OP. Alternatively, you can use cURL.
The answer to this is very needed today because not everyone wants to use cURL to consume web services. Also PHP does allow for this using the following code
function get_info()
{
$post_data = array(
'test' => 'foobar',
'okay' => 'yes',
'number' => 2
);
// Send a request to example.com
$result = $this->post_request('http://www.example.com/', $post_data);
if ($result['status'] == 'ok'){
// Print headers
echo $result['header'];
echo '<hr />';
// print the result of the whole request:
echo $result['content'];
}
else {
echo 'A error occured: ' . $result['error'];
}
}
function post_request($url, $data, $referer='') {
// Convert the data array into URL Parameters like a=b&foo=bar etc.
$data = http_build_query($data);
// parse the given URL
$url = parse_url($url);
if ($url['scheme'] != 'http') {
die('Error: Only HTTP request are supported !');
}
// extract host and path:
$host = $url['host'];
$path = $url['path'];
// open a socket connection on port 80 - timeout: 30 sec
$fp = fsockopen($host, 80, $errno, $errstr, 30);
if ($fp){
// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
if ($referer != '')
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);
$result = '';
while(!feof($fp)) {
// receive the results of the request
$result .= fgets($fp, 128);
}
}
else {
return array(
'status' => 'err',
'error' => "$errstr ($errno)"
);
}
// close the socket connection:
fclose($fp);
// split the result header from the content
$result = explode("\r\n\r\n", $result, 2);
$header = isset($result[0]) ? $result[0] : '';
$content = isset($result[1]) ? $result[1] : '';
// return as structured array:
return array(
'status' => 'ok',
'header' => $header,
'content' => $content);
}
In addition to what Salaryman said, take a look at the classes in PEAR, there are HTTP request classes there that you can use even if you do not have the cURL extension installed in your PHP distribution.
There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/
private function sendHttpRequest($host, $path, $query, $port=80){
header("POST $path HTTP/1.1\r\n" );
header("Host: $host\r\n" );
header("Content-type: application/x-www-form-urlencoded\r\n" );
header("Content-length: " . strlen($query) . "\r\n" );
header("Connection: close\r\n\r\n" );
header($query);
}
This will get you right away
