Looks like Twitter and Disqus both use the easyxdm library - http://easyxdm.net/ (I was needing to do this, and google sent me to your site first! Small world...)

dmjones - How to use variable variables in PHP

The alternative was suggested and works well $this->{'_' . $key} = $val;

I wanted to use this avenue in order to populate private variables of a class using an array as input. However, the values don't seem to stay or aren't even assigned to the private vars. Any ideas? class aClass { private $_fruitA; private $_fruitB; private $_fruitC; public function set($inputArray) { foreach ($inputArray as $key=>$val) { $var = "this->_{$key}"; $$var = $val; //prints nothing print "this->_$key: ".$this->_fruit."\n"; //prints the $val assigned in $inputArray print "\$\$var: ".$$var."\n\n"; } } } $fruit = new aClass(); $fruit->set(array('fruitA' => 'apple', 'fruitB' => 'banana'));

I agree that would be a good feature to add. �Glad you got it working.

Ok. I got it implemented using a hash tag to pass the monitor id and then getting this value from the $request ($info['url'] doesn't retain the hash tag on the URL for whatever reason). This way, by using a hash tag, I figure there is no possibility that it'll ever change the URL that is checked. Still it'd be cool, if RollingCurl had a way to pass a value without affecting the URL. But this is working for now. Thanks for sharing RC!

You only list examples of HORRIBLE, poorly designed/implemented captchas and say "see how bad they are".

JRO - Reading GET variables with JavaScript

JRO — Wed, 14 Dec 2011 06:00:35 +0000

This works better: function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("&"); for (var i = 0; i < vars.length; i++) { var pair = vars[i].split("="); if (pair[0] == variable) { return unescape(pair[1]); } } return false; }

not to lurk, been trying to get this to do anything for hours now. Before i grind my teeth into dust, could someone be so kind as to show any of this working in context? say like www.whatever.com/index.php?var1=hi is the url then the page w the script outputs var1 and prints hi? I know php well, new to js, getting a tad crazy over here...

Sure, an easy way to do this is to add a GET variable to the end of the URL you are fetching (ie. ?mysql_id=42) and then parse out that ID when the request completes from the CURL info array.

Hey Josh, Is it possible to pass a value (e.g. $row['id']) into RollingCurl so that it's available for use within the callback function? foreach ($rows as $row) { // Add each request to the RollingCurl object. $request = new RollingCurlRequest($row['url']); $rc->add($request); } (Basically, it's the MySQL primary key for each row ($row['id']) that I'm trying to pass and make available within the callback function.) Thanks.

Hope so too. I have a workaround now (which has nothing to do with the script, but makes me not have to use it in these cases). thx anyway for this great share and for the quick reply!

I've had multiple reports of issues w/ those 2 browsers (see the comments above). Hopefully I'll find the time to dig into this more soon.

Your script does not seem to work when running IE8 or 7. Hoped your script would give a solution as I was having trouble with this earlyer myself.. In my own case It seems like when trying to access the parentwindow by doing parent.window.postMessage > IE8 will throw an access denied error which I can catch and act upon appropriately. However when trying to send a message to the child window inside an iframe by using document.getElementById("myIframe").contentWindow.postMessage > this will throw no error, though nothing will hapen neither so I am left with an unhandled scenario. Didn't go indepth with your script but a quick test of your demo shows that showing the message from within the iframe works as with my own scenario and the message from the main page to the iframe does not work.

The export tool in not under file in Firefox 4.0. It is controlled from the bookmarks menu under "show all bookmarks". Since your post is coming up in searches toward the top, you may want to revise it.

I tell people all the time that all these captcha things were broken a long time ago. For some reason they don't listen and add some form of captch to their site anyway. I do like the hidden field suggestion that is definitely something to think about. The thing that bugs me the most about them is a lot of them are almost impossible to figure out what letters they are. I had one the other day at a social bookmarking site, and there was no way a real person could have figured out what it said. Anyway great article.
