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.

Extreme extension

I have created, all my site content structure with this modue, with so many custom fields.

I suggest this to other users, it saves a lot of time, with your content structure.

Best CCK



Posted on 07 December 2013
I’m using K2 to my Multilanguage Joomla 2.5 Website with 2000 articles. It’s working very nice and it has all the missing features that Joomla content doesn’t. I really like the tag system, the way it handles the categories especially the inherit parameter. The extra fields have limitless possibilities! The only con is that it gets a little bit slowly to load with some articles. K2 is probably the best open source CCK for Joomla and the best thing is that it is supported by many Templates and has lots of 3rd party plugins.

Great Addition to Joomla



Posted on 30 November 2013
I have been using K2 for a year now on one of my six Joomla sites and it has been an excellent addition. It gives so much more flexibility over the basic Joomla CMS. Once you get over the learning curve it's easy to use. I just get one category looking like I desire and then let new ones inherit the settings from it and voila the other categories look great too. Then I go back and tune it a bit for the custom look and feel. This works well with SH404SEF too. Nice work.

waste of time

K2 is not offering anything special that joomla 3 articles doesn't already have.



And not to mention how difficult is to move K2 items back to joomla articles.



They didn't put anthing new in K2 since... wait a minute, never?



K2 is the past, don't waste time with it, 2 years with K2 was enough. If you don't want to use joomla articles use any other extension but not this granny extension.
Owner's reply: This is K2. You either love it or hate it :)

In both cases there's a lot of passion hidden in the background. I'm not gonna go all Sigmund Freud here, but the fact that you don't bother to provide a few valid points as to why K2 doesn't work for you and you're just being vague, I can only guess that you're one of those people who demand features for K2, which are only to be applied by those few people asking them. Sorry if we didn't put one of the features you asked in K2 and that made you angry, but thankfully, most K2 users don't see it this way. Most K2 users understand what open source is. They know it takes time, effort and money to build. Lots of all three.

And to wrap it up: K2 is the only Joomla! extension supported by all professional template clubs and that speaks for itself.
I write mainly due to a previous negative statement.



I am using K2 for several years and it is terrific component for Joomla.



Problems rarely occur if you use a good template, not just the "Most Beautiful" which have many holes, and they cause problems with K2, and it is not the fault of K2, and the most common template.



So I advise you to choose the templates, not only in terms of their wyglądau, but also in terms of the quality of the code.

K2 rocks!

we build websites only with k2 component cause is the best component ever, we have done with eshops, deal websites, portal etc.



great work!



thanks for all joomlaworks!

Must and Must have

I'm shocked to see K2's JED rating is below 4. Please guys, take care while rating. Because, this one is star among the extensions in JED which is also FREE. Whenever I need to develop a custom module or plugin, I just go and refer their code. A very professional & clean component. I convey my sanctification and bless their fantastic development team.

Nice

Thanke you for K2. I think it's just the extension that should be used in every website.

Good Extension



Posted on 23 September 2013
This extension is working really well on our new website and doing all that it states.
I have used K2 in quite alot of projects and i really love it. It is easy to configure, as also its templating system is excellent.



It will work for most of the cases, but i faced its limitations when i tried to built a quite complex content structure for one of my projects.



So i came up with ~20 content types (extra field groups), some of them with more than 40 or 50 extra fields.



This was a "disaster" since K2 become very slow for these content types (items) ... and now i am trying to find alternatives :( ....
Owner's reply: K2 is *THE* extension for pushing Joomla! to its limits. It's the very reason top Joomla! sites worldwide use K2.

K2 has richer content options compared to the default Joomla! article system and yet it's a lot faster compared it. Now, how did you manage to make a slow site out of K2 remains a mystery...

People some times confuse crappy hosts with Joomla's performance. I'm 100% certain that's the case we deal with here. And in this case, any CMS would perform slowly...

Greate extension!

I really enjoying it :)



Thanks!

Good, but not for me



Posted on 07 August 2013
First off, I like K2 as a Joomla extension. BUT, In my opinion, the trade-offs don't overcome the benefits. I'll admit I'm no high level developer or admin, but in my mind, K2 really doesn't add that much to Joomla. Back in the J! 1.X days, when you only had two layers of categories to work with K2 was a huge improvement. But these days, without that limitation in J! core, I don't see the big advantage to using it. Now, the disadvantage is that you lose the ability to integrate with a lot of extensions. By this, I mean that pretty much any extension will work with J! core articles, but they're hit or miss on whether they'll work with K2. So for me, the tradeoff isn't worth it. Other drawbacks include the performance hit you'll take by running another program within Joomla and the hassle of dealing with another stylesheet.
