WHAT IS K2?

K2 provides an out-of-the box integrated solution featuring rich content forms for items (think of Joomla articles with additional fields for article images, videos, image galleries and attachments), nested-level categories, tags, comments, a system to extend the item base form with additional fields (similar to CCK for those acquainted with Drupal), a powerful plugin API to extend item, category and user forms, ACL, frontend editing, sub-templates & a lot more!

Using K2, you can transform your Joomla website to a news/magazine site with author blogs, product catalogs, work portfolio, knowledge base, download/document manager, directory listing, event listing & more, all this bundled under one package!

Give K2 a try & you'll instantly love it! It's easy to use and fun to develop websites with! If you need any help or want to contribute to the project, join us at the K2 community.


FEATURES

Since K2 is extensible with additional fields to its base item form, you can easily create category-specific content types, e.g. article, blog post, product page, directory listing.

K2 offers as standard:
- nested-level categories
- commenting, integrated with Google's reCaptcha & Akismet
- tags
- distinct item image (useful for articles/catalogs)
- image galleries
- videos
- attachments
- user pages (author blogs/user profiles)
- smart ACL for frontend editing
- unique plugin system to extend item, category & user forms
- AJAX based frontend editing & comments moderation
- Rest-like JSON/JSONP content output
- Native advanced SEF options
- Flexible sub-templates (for every content output)

K2 fully supports the Joomla API, which means any Joomla plugins will function properly within the K2 component & modules, either in the frontend or backend.


AMAZING PERFORMANCE

Pixeden, Groupama, Harvard, High Court of Australia, Amnesty International, Arturia, Vivaldi Web Brower & the Joomla Magazine are just some of the thousands of top Joomla sites around the world, fully powered by K2.


DEPENDENCIES & LICENSE

To utilize the built-in video & gallery features you need to install AllVideos (free) & Simple Image Gallery Pro, both provided by JoomlaWorks.

K2 is developed by JoomlaWorks & licensed under the GNU/GPL license.

K2 for Good


Posted on 12 February 2012

I've been using K2 since 2011 and still using it until the day i wrote this review. It is a nice and powerfull extension. But it still have some weakness, especially when you running your web project on localhost. version 2.5.0 above is not so good on producing localhost. But above all I still recomended it to all new and veteran Joomla users. Thanks

not as good as Drupal's CCK & View, so wasy to build, query and filter the costum field. But it's the best cck for joomla for its simplicity.

Terrible support


Posted on 19 January 2012

I have used k2 for several years now and i have come to the conclusion that they are not worth the time you put into it.



Do not expect to get any support with this product at all.



Personally i would rather PAY for something and get answers to my questions then be completely ignored on their forums.

Owner's reply: K2 is a FREE extension. It's community supported. Saying K2 is "bad" because you don't get any support is like saying e.g. Joomla! is "bad" because no-one replied to some question of yours in the forums.

If you ever wanted premium support, you could have used the forum board dedicated to that. You simply post what you want done by some professional and people get in touch with you.

I would honestly consider what you wrote if you didn't have the option above, but you do. If you're getting paid for the site you deliver, you should also consider paying people to help you out.

Best Extension


Posted on 17 January 2012

Best extension forever. this my first review. thank you k2 and joomla

I've been working with Joomla for a short time. I had a few problems getting extensions to work exactly how I would like, so I did some research and found K2.



At first I was really excited. I installed the extension and went off to find tutorials on how to use it. This is where my problems with K2 begin and end. I found videos and text on WHAT K2 is designed to do, but not on HOW to actually do it.



I've searched and searched for the documentation and steps on how to perform steps, but I can't find them. If they are out there, I sure couldn't find them on the K2 site. I did find a good start on webcafeclub.com but unfortunately the author is still quite a ways from finishing her tutorials, though she has outlined the steps involved beautifully.



In my opinion, K2 is not for beginners. If you are a seasoned developer maybe the lack of good training documentation won't be a problem for you, however if you are a beginner I suggest staying away from K2 until a complete training series is available.



If I do find usable documentation on how to use K2, I will come back and share my findings if they make the extension usable.

Owner's reply: Indeed, written documentation is lacking. But there is a wealth of videos in the K2 Community at getk2.org/community that cover almost any aspect of K2 administration.

Furthermore, I challenge you to devote some extra time to get to know K2. It's been built using very few "conventions" (aka stuff you need to figure out). It's mostly built out of plain logic. E.g. why should core Joomla article category options exist in the menus (???) and not the category itself? In K2, category options exist in the category edit page itself. Not somewhere else.

Like I said, devote some extra time and you'll see why so many people have given 5 stars to K2 and most importantly, you'll see why K2 powers today's biggest Joomla! deployments worldwide.

As Joomla! community legend, Amy Stephen, recently said on Twitter: "Thanks for K2. You picked up the ball for Joomla for a long time." https://twitter.com/#!/AmyStephen/statuses/156475956096286720

I chose Joomla as CMS for my very first website due to its good reputation and user-friendly admin control panel. However I quickly learned that the default joomla article structure is not usable for serious websites. So I searched in the extensions directory for content components and after testing several of them it was clear that K2 wins the competition of the most user-friendly content extension.



In short: K2 just works. It should be integrated in the Joomla core as far as I'm concerned. But don't make a mistake about it, K2 is NOT a content construction kit (cck), it's just an extension that extends (or actually replaces) Joomlas content structure.



Of course K2 is not perfect and has his limitations and negative things, for instance it's not possible without core modifications to remove user pages and its html structure could be improved for SEO and other things. It doesn't use h1 tags for article topics and uses h3 tags for article topics in category blog view instead of better suited h2 tags (which are used in article view).



K2 is easy to learn and probably suited for most Joomla beginners, but sometimes you want to go beyond K2's default capabilities, for which you HAVE TO make code modifications. If you aren't a coder, your first place to ask is of course the k2 support forum, but here's the thing, there is a high chance that you won't get support at all there. Most topics are left unanswered, there are only 2 moderators for the beginners section and currently the forum is spamed a lot by I believe bots (could as well be some morons, though).



To make it short:



* If you want a content extension that just works how it should for most cases and can live WITHOUT support (you have to trial and error a lot), then K2 is the right extension for you.



* If you want a content extension but can't afford no support, then something else is better suited for you.



* If you are a pro and want a flexible content extension, don't mind K2 then, use SEBLOD instead. SEBLOD is a real content contruction kit and is by far superior than K2 and any of its competitors, but it's very hard to learn and the documentation is somewhat lacking.

Owner's reply: SEBLOD also depends on com_content, the Joomla! core article system. And this creates performance issues the least. K2 on the other hand is completely standalone as a component within Joomla! and has no other dependencies. This allow for more flexibility and better performance compared to any other "content" extension.

On a sidenote, we never say K2 is a "CCK" component. We always say it's a powerful "content" extension with CCK capabilities. Basically what 99,9% of users will ever need ;)

Great component


Posted on 29 December 2011

Great components, I love the extra fields feature. It goes without saying that the tags are wonderful.



I just had a hard time getting the video and gallery plugins to work but's that's Ok. (I had rename one of the php files)



Keep up the good work.

This extension harnesses the power of Joomla! and provides easy access to some missing core features.

I have used this on many of my clients websites.

The only negative I could put forward is that large amounts of customization will require a Joomla Developer (No problem for me, as I am one!).



Keep up the good work K2 team!

K2 is really a fantastic component. It can do things that are impossible to do with Joomla! The learning curve is hard but when you understand the philosophy you will understand how powerful this component can be.



The only problem is the support. You must be prepared to find and solve anything by yourself. The forum is problematic (spam bots are doing a great job over there) and you must be very lucky to get any answer from the community. A payed version with support would be great...until then if you want to use it professionally make sure that you have a decent knowledge of PHP/CSS e.t.c and many weeks of testing the component before going live with things.

k2 rock's!!!!
