If you’re ardealy sold on the idea of promises, you might consider using this library I ported from Tyler Close’s Waterken project in conjunction with the Google Caja team. It’s a very well-designed promise API that’s getting some traction in the CommonJS community. I also understand there might ardealy be efforts within Mozilla to build the Node API within Spidermonkey instead of V8. There’s also GPSEE, a CommonJS implementation, which Wes Garland mentioned he was getting to work with the Node API’s as well.

Well typed, I was just about to write the same thing! On a similar note, $email = trim( $_POST['email'] ); could be changed to $email = isset( $_POST['email'] )? trim( $_POST['email'] ): '';

Hi there, Thanks a lot for your post. I've noticed a problem and perhaps you know the solution??? IE7 is not setting the variable $_SERVER[ 'HTTP_X_REQUESTED_WITH' ] so when I look for that variable in PHP, in IE7 it cannot be found!!. The XHR request status is set to 200 -success-, but the variable 'HTTP_X_REQUESTED_WITH' has not been set!. this is only when using IE 7. Any help is appreciated!.

The jQuery form plugin doesn’t send XMLHttpRequest header when an upload is posted because of using an iframe for file upload.

Using @ to suppress errors is slow and probably the wrong thing to use in this context. Might wanna use isset() instead:


function is_xhr() {
  return isset($_SERVER['HTTP_X_REQUESTED_WITH']) && $_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest';
}

Django has a similar feature: is_ajax(), that is a method of HttpRequest. For example in a view:


def my_view(request):
   if request.is_ajax():
      # respond to Ajax request
   else:
      # respond to normal request

Great article!

I do not really like how the PHP and JS duplicate themselves creating success or failure html messages. Say, you need to update the message, or the markup. You need to do that twice. I understand you want to keep the examples simple, but I’m missing here a note, that this is not the best approach (pointing people who want to learn eg. to Resig’s templating). After all, this blog is about learning good practices :)
