Reflex Feedback 0.3

A small update to the Reflex Feedback Widget,

  • Design tweaks (border, box-shadow, border-radius on textarea; padding-top on copyright)
  • widgetPos argument added to init(), valid values => ‘left’, ‘right’

So you can now position the widget on the right edge of the page like this:

Reflex.init($('body'), 'controller/post_feedback.php', 'right');

More info about the widget itself can be found in the original blog post.

Reflex Feedback 0.2

An updated version of the Reflex Feedback widget is now up.


  • New icons done by myself and released under the same license as the code; no longer using the ones by Yusuke Kamiyamane. This should also make it easier for those who want to do custom modifications as they don’t have to worry about an attribution requirement for the icons.
  • New menu layout and new buttons. Now using jQuery UI buttons for everything, which allows for compatibility with jQuery UI styling, ThemeRoller, etc.
  • CSS fixes to prevent some inherited styles from screwing up layout.

Reflex Feedback widget

I worked on a small AJAX widget for user feedback built atop jQuery UI: Reflex Feedback. It’s inspired by the widgets you see from services like Get Satisfaction and UserVoice, but much simpler and it’s a frontend-only widget, how you handle the feedback info on the backend is up to you.

Here’s what it looks like.

And here’s what the tag that opens the dialog looks like:

reflex feedback widget tag

To use it, download or clone the ReflexFeedback repo from bitbucket

Place the .js file wherever you’d like but the /reflex.content folder should a subdirectory in the same folder as the page loading the .js file. Load reflex.js as you would any other javascript file:

<script type="text/javascript" src="js/reflex.js"></script>

Call Reflex.init() to add the widget to the page. The first argument is the DOM element to attach the additional HTML/CSS code to. The seconds argument is the server-side script to call when the user clicks Send Feedback.

Reflex.init($('body'), 'controller/post_feedback.php');

That’s it for the frontend. You should see the tag show up in the right-hand corner and when clicked the dialog open.

For the backend, the AJAX call to send the feedback info will send a POST request with 2 fields: feedback_type, feedback_txt.

Reflex expects an XML reply from the server:


ok indicates a successful result, any other reply is considered an error.

A successful result will close the dialog and show another with a thank you message.

For an error, a message is shown below the Send Feedback button, informing the user that an error has occurred and to try again.

As for what to actually do with the feedback, that’s up to you, but what I’m doing is sending myself an email with the feedback info. I’ve posted my PHP script below; feel free to use it, modify it, etc. If you do use this code, be sure to fill in your mail server credentials and a from address; you’ll also need PEAR’s Mail package installed.


require_once "Mail.php";
require_once "Mail/mime.php";

header('Content-type: application/xml; charset=utf-8');
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n";

if(!isset($_POST['feedback_type']) || !isset($_POST['feedback_txt']))
echo "<reflex><result>error:missing-arguments</result></reflex>";
$from = "...";
$to = "...";
$subject = "Feedback from user...";

$feedback_type = $_POST['feedback_type'];
$feedback_txt = $_POST['feedback_txt'];

$bodyHtml = "<html><body>";
$bodyHtml .= "<p>Type: {$feedback_type}</p>";
$bodyHtml .= "<p>Feedback: {$feedback_txt}</p>";
$bodyHtml .= "</body></html>";
$body = $bodyHtml;

$host = "...";
$port = "...";
$username = "...";
$password = "...";

$headers = array('MIME-Version' => '1.0rn',
'Content-type' => 'text/html; charset=utf-8',
'From' => $from, 'To' => $to, 'Subject' => $subject);

$smtp = Mail::factory('smtp',
array ('host' => $host,
'port' => $port,
'auth' => true,
'username' => $username,
'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail))
$err_details = $mail->getMessage();
echo "<reflex><result>error:send-failure</result><details>{$err_details}</details></reflex>";
echo "<reflex><result>ok</result></reflex>";


That’s all for now. I’ll work on more features and options for customization in the future. You can see the widget in action over at


hotspotdot is my entry into Microsoft’s My App is Better Challenge. In a nutshell, hotspotdot allows you to locate and tag “hot spots” that are important to you, allowing you to create a personal database of hot spots.

It’s a very simple app, utilizing PHP, SQL Server 2008, jQuery, jQuery UI, and the Google Maps API. I wrapped thing up in under 2 weeks, but in order to make the August 25th deadline there were a few features I didn’t get a chance to put in, such as preloaders, icons on the map, and searching by tag. I’ll probably devote some time to these in the coming weeks.

The goal of the contest was to create something showing off the power of SQL Server and Microsoft’s new PHP for SQL Server 2.0 drivers. I used the new PDO driver which was pretty sweet – very simple, elegant API. Two things in particular that impressed me were transactions (very nice for doing multiple inserts or deletions) and a consistent and well designed exception model (makes error handling much easier and especially powerful when combined with transactions as failed queries don’t effect the database [code jumps to exception handler before commit() is called], so no chance of junk being inserted). Error messages, in general, were also much more descriptive than those I’ve encountered with MySQL.

Finding a server proved difficult. I got a shared hosting solution, but the host was unable (though I suspect unwilling) to install the PHP for SQL drivers. So I ended up getting a virtual private server, but this only came with SQL Server Express and I used some features (see below) that prevented a migration. In order to avoid purchasing an SQL Server 2008 license (way out of my budget), my final solution was use the shared hosting server for the DB and the VPS for everything else. Hence the reason for the site being located at the my. subdomain, which maps to the IP of the VPS.

SQL Server 2008 is a fine system (despite some annoyances with the management studio)… though it’s really just a solid database system, which isn’t bad, but there’s nothing really impressive or creative about that. It’s not really leaps and bounds above a cheap solution like MySQL. The contest was about SQL Server, so I tried to do something that utilized a fairly unique aspect of the system: the geography data type. I wasn’t too impressed. It simply holds a (longitude, latitude) pair in a certain format, nothing more. The one big advantage of having a vector type like this would be doing comparisons based on distance but, as far as I could tell, this isn’t supported (my queries failed). Worse yet, in SQL Server Management Studio the display of the geography type is in hexadecimal, making things very cryptic… I couldn’t help but wonder why this is any better than using 2 columns and storing the longitude and latitude values independently. That said, the idea of richer/more-complex data types within a relational database is a pretty cool idea and it would interesting to see it taken further and beyond its current, primitive state.
