Disqus comment system integration Helper
This article is also available in the following languages:
Integrating a disqus comment system (http://disqus.com/about/) with cakephp is really simple. To make it simpler, here is an Helper that should do almost all the dirty work for you.
First of all, you need a disqus account. You can get one here: http://disqus.com/comments/register/
Then, grab this code and put it in ./app/views/helpers/disqus.php
As the header says, "In function makeRepliable, I set the projectName somewhere in my configuration files, remember to change this variable to something that suits your needs.". You really need to do it :)
Add the helper in app_controller, or wherever you need it...
and we are almost done: just place this where you need to show the comments thread and form
--- optional ---
use this to show the last comments in your sidebar, or wherever you like it to be
this goes after every permalink pointing to a page where you have a disqus thread
and last of all, this one makes all of your previous links a comment counter (eg. 0 comments, 3 comments)
Then, grab this code and put it in ./app/views/helpers/disqus.php

echo $disqus->repliesLinkCounter();
Just because a tool makes it easier to integrate a paid service doesn't mean it shouldn't be made available on here. If I have a client that wants to use this service on their site, this helper will save me a ton of time that I would have spend writing it myself.
I understand where you're coming from, but I am a fan every free piece of code I can get to help with integration.
