Facebook API Error Codes

API, Facebook

It’s rather comical, you do a search for error codes, a link comes up taking you to a page on Facebook that’s blank. Well played. If you’re receiving an error when using the Facebook API, post a comment so I can begin to inventory them.

Note which library you’re using, and the error number along with the message. If you know the deeper meaning behind an error, let me know so I can include it within the list as well.

(#100) Message Failed
(#210) User not visible
(#341) Feed action request limit reached

Zend Framework Twitter and oAuth in 1.10.7

Code, oauth, php, twitter, Zend Framework

Today I wanted need to switch out some implementations I have in twitter. I was using HTTP Basic for authentication as were most. I went through the Zend Oauth docs, and combined with their examples and those of Pádraic Brady I got this working fine.

I’m not going to give a step by step, as I’m assuming you’ve already read various docs.

I broke my files out like Pádraic, so if you’ve read his than you’ll understand mine.

First, my config file which is included within each subsequent file.

$config = array(
        'callbackUrl'    => 'http://www.example.com/callback.php',
        'siteUrl'        => 'http://twitter.com/oauth',
        'consumerKey'    => 'XXXXXXXXXXXXXXXXXXXXX',

My index page is the starting point of the authentication process. Our persistent storage for this example is in session, though in production I’m using a database.

include_once './config.php';

    // $config is from our include!
    $consumer = new Zend_Oauth_Consumer($config);

    // fetch a request token
    $token = $consumer->getRequestToken();

    // persist the token to storage
    $_SESSION['TWITTER_REQUEST_TOKEN'] = serialize($token);

    // redirect the user

The callback url specified will now be triggered

include_once './config.php';

// Check if _GET is set and that the request token is being returned
if (!empty($_GET) && isset($_SESSION['TWITTER_REQUEST_TOKEN'])) {

    $consumer = new Zend_Oauth_Consumer($config);
    $token = $consumer->getAccessToken($_GET, unserialize($_SESSION['TWITTER_REQUEST_TOKEN']));

    $_SESSION['TWITTER_ACCESS_TOKEN'] = serialize($token);

    // Now that we have an Access Token, we can discard the Request Token
} else {
    // Mistaken request? Some malfeasant trying something?
    exit('Invalid callback request. Oops. Sorry.');

// Lets just pass on to a test posting page

Finally, if all went to plan and the user authorized our application, we can pull in their access token and do as we need on their behalf.

include_once './config.php';

// Verify we're good to go

    // Unserialize and add the token to the config
    $token = unserialize($_SESSION['TWITTER_ACCESS_TOKEN']);
    $config['accessToken'] = $token;

    // Pass the config into Twitter, and act upon the users account
    $twitter = new Zend_Service_Twitter($config);

    $twitter->status->update('I am so posting from your account. Rock!');

That’s all really. I do wish the Zend Service Twitter docs would be updated to reflect some examples. I saw in SVN Pádraic has already changed some of the docs, they’ve just not been updated on site yet.

Thanks to the documentation authors and those I borrowed from to get my working example going and so I could more easily move forward with this project.

Zend Soap Client timeout

php, Zend Framework

I’m working with a web service that’s showing to be slow at times. The default timeout in PHP is 30 seconds currently, so waiting around for it to timeout kinda sucks.

I decided to set the timeout to 10 seconds, to my surprise the timeout code is completely commented out in the class.

However they do provide a setStreamContext(), so I set http to timeout after 10 seconds like so:

$context = stream_context_create(array('http' => array('timeout' => 10)));

When the service slowed down to 15 second wait times, it died out early like it should have. I’m catching the exception, which isn’t pretty. Wish I knew when it was timing out, so I could log that specific case.

Zend Form Element Radio and Default value

Code, Zend Framework

I setup a Zend Form object and needed radio buttons, but also needed a default value. Took me a few minutes to find, but here’s an example of use.

 * Setting some values for our radio buttons.
$options = array(
    '1' => 'Option 1',
    '2' => 'Option 2',
    '3' => 'Option 3'

 * The array('value' => 2) below sets our default value.
$radio = new Zend_Form_Element_Radio('elementName', array('value' => '2'));

Upgrade Zend Framework in Zend Server CE

zend server ce

First off, this isn’t meant as a tutorial, but more of a general way of handling various libraries in this situation.

We’ve recently started to use Zend Server CE on our development machines at work.

With the release of Zend Framework 1.9, we wanted to upgrade but still maintain previous versions.

When I download the framework, I prefer to use svn and grab the tag, in this case: http://framework.zend.com/svn/framework/standard/tags/release-1.9.0/

The structure I chose was:


I then created a symbolic link to the version I want and put that in my include_path.

Example: /usr/local/zend/shared/ZendFrameworkLibrary/ -> /usr/local/zend/shared/ZendFrameworkSource/1.9.0/library/

Now with each upgrade, I only update the symbolic link and each application is switched to the new version.

Have a better way? Let me know, I’m always interested in learning.

Old code.

Code, php

I love coming across old code *cough* garbage *cough*

The purpose of this was to take a title, and create something url safe and in the fashion a client was wanting. The first function was old code, so don’t blame me.

function cleanUrl($url)
  $find =        array('/--/', '/ - /','/ /', '/!/', '/"/', "/'/", '/--/');
  $replace =    array('-', '-', '-', '', '', '', '-');

  $result = strtr($url, "`~@#$%^&*()_=+|[]{};:,./<>?", "---------------------------");

  return strtolower(preg_replace($find, $replace, strip_tags(stripslashes(trim($result)))));

Isn’t it horrible?

I rewrote the function to…

function cleanUrl($url)
  $url = strtolower($url);

  $url = preg_replace("/[^a-z0-9\s+]/", '', $url);
  $url = preg_replace("/[\s]{1,}/", '-', $url);

  return $url;

That makes me happier.

Lazy day


Today is rainy and full of nastiness. (Thanks Ike!)

I should have gotten out to play disc golf while the weather was beautiful, I just didn’t feel too hot.

Called my sister Meagan a few times, her voicemail is picking up so I’m yelling in a demonic sounding voice and hanging up. Hopefully it freaks them out a bit. If not, well, no loss.

Work is going well, moving forward on some things and looking good.

Snapped a great picture of my brother in law, and his wifes brother being dorks. Put it up on my facebook in the mobile uploads.

This turned into more of a journal entry, rock on.

Ewerl Function


Ewerl is a new URL rewritting site with cool features.

Here’s a simple function to return the Ewerl url. It’s only being used for the main url, but could easily be adjusted to return an array. I just didn’t have a need for it in my case at this time.

 * Returns an Ewerl url if available.
 * Otherwise the original that was passed in.
 * Returns false if..
 * 1. JSON extension isn't installed.
 * 2. No url was entered.
 * 3. No response from server.
 * @todo Add URL validation.
 * @param string $url
 * @return string URL, or false.
 * @author Casey Wilson 
function getEwerl($url) {
	 * Verify JSON extension is loaded.
	if (!extension_loaded('JSON')) return false;

	 * Url wasn't passed
	if (!$url) return false;

	 * Assign / Prep vars.
	$postUrl = 'http://ewerl.com/api/v1/make/url=';
	$urlEncoded = base64_encode($url);

	$response = file_get_contents($postUrl . $urlEncoded);

	if (!$response) {
		return $url;

	 * Should have returned a JSON object.
	$jsonObj = json_decode($response);

	 * If either Status not set, or status is false, return original url.
	if (!isset($jsonObj->status) || $jsonObj->status == 'FALSE') {
		return $url;

	return $jsonObj->url_main;

My expierence with jQuery thus far hasn’t been to bad. I’m starting to see the power and simplicity of it.

I’ve never been a JS guy, never been in a position to really need to do much with it since I’ve basically always been a backend coder. I need to really jump in there, get a good feel for both JS and jQuery. So far though, I can say I’m really starting to like it, only been at it a few days thus far so we’ll see here soon what the final say is.

Thanks to good friends, and long late night chats with people smarter than I.

The open source community as a whole rocks.

Url to TinyUrl Function


I needed to transform some long urls into tiny ones :p

Figured I’d post something up here that may be useful to someone else.

Code was updated.

 * Get TinyUrl for $url
 * @param string $url Must be a valid url
function getTinyUrl($url) {
	if (! $url) {
		return false;

	if (strlen ( $url ) < 30) {
		return $url;

	$response = file_get_contents ( 'http://tinyurl.com/api-create.php?url=' . $url );

	return ($response) ? $response : $url;
