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.


WHAT NEXT?

Try K2! Install it, hit the "import" button to bring your Joomla articles inside K2, start playing with the component to see the flexibility it provides first-hand. Moreover? You no longer need a dozen of components & even more modules to do things like run a news site or a blog. Drupal & Wordpress have certainly met their match now!

The component is really great, combined with K2 Store it's even greater:). Thank's a lot.

Good but...0 support?

Good for a free extension,not excelent...and has a lot of bugs yet.For example I have K2 on a site and have set the 'print' and 'email' buttons to show on all items. The Print button works fine but when I test the Email button, the form appears but upon hitting send I get an error message, "Email could not be sent".

So if nobody helps then why using it?

SEO


Posted on 12 April 2012

I like K2, its one of most popular joomla componets. and I'm really sorry to say that this component is not SEO friend because each item in the website is reachable with different URLs. Since 2 months ago that I installed K2, I have thousands of duplicated articles in my "google webmaster" account, and this problem will affect strongly on google organic traffic, so your site will die as my website. I tried to find a solution on official K2 forum but there were many request about this problem without reply or solution.

Owner's reply: This is not entirely true. Let me explain...

Duplicate entries depend on your menu structure. If you have a menu that maps all your K2 categories (or at least the most imporrtant ones), then you won't have duplicate entries.

To further mitigate that, one of the things we want to add in K2 v2.5.7 is canonical URLs to prevent Google from seeing duplicate item entries (if they exist).

That should further improve K2's SEO features.

Unlike the default Joomla! content or other CCK extensions, K2 already sports much better SEO. From the "read more" links which contain the item's title, to the images, to author links etc. etc. ;)

I love this component, use it on just about every site I do. I have always been impressed with everything you guys do! Keep up the good work. Cheers.

Good Component... But...

As Non Commercial Component, K2 is Simply Great, and I really appreciate the efforts of the programming team.

But its not like other open source applications, it lacks documentation, tutorials and training for beginners, specially on the extra fields sections.

As simple Joomla! user I was fully satisfied with standard Joomla CCK (if it can be called that). Few months ago I just found it's not enough and just doensn't fit my needs and requirements. So I've checked some free CCKs here and there and finally found K2. I was just overwhelmed by countless options, configuration stuff, possibilities, etc. However - after few hours with K2 Forums, some help-sites and dozens of teste, tries and mistakes I (at last) found this component really easy to use. It wasn't hard to learn, you just need to spend some time with it and play with anything you can find there (on some backup copy of your site, or fresh Joomla! installation for testing purposes only).

Now I can say that K2 is probably the best free CCK ever created for Joomla! It perfectly fills all my needs (and probably yours) - tags, comments system, social buttons, images, videos, extra fields and 10 billion/trillion/gazillion configuration options... looks scary at the beginning, but after few hours the best becomes the beauty, and the curse of complexity becomes a blessing.

I think everyone should give it a try - remember it's free, so it will only cost you some of your time!

Pure Joomla Gem


Posted on 28 February 2012

I just can't build my sites without it! Yes, it has been a long journey learning how to use and customize it, and yes, sometimes I've felt like taming some wild beast, but if you want one of the best tools in your toolbox, you gotta invest time and energy to get to know it.

JoomlaWorks and Fotis - Thank You Very Much for sharing this gem with all of us! It has opened a lot of new doors for thousands of "joomlators". Keep up the good work!

Awesome component

Extends core Joomla functionality so well that I wouldn't ever use Joomla without it anymore.



Don't let some of the poor reviews on here put you off - it is not difficult to use, the css is a dream to edit, with very little effort it turns a bog standard Joomla site into a fully featured magazine style website.



An extremely powerful extension. Great job JW.

What can I say about K2, it is like reinventing the wheel. It offers everything the core Joomla! doesn't - comments, tags, predefined functionality for videos, galleries, main picture. It's plugin and templating system is incredible and allows very flexible solutions.

You can build amazing things with K2 with lesser time than with the core content extension.



Is there more to want? Well, sure, but still K2 is far ahead in the combination of power and simplicity of use.



What I would love to see? - IP of commenters, blocking/banning commenters by IP, E-mail. Maybe a non-intrusive anti-spam solution like Akismet or Mollom would be great. Of course there are other things to like (a bit improved picture management - auto-crop or so), but still believe me K2 is far far ahead.

Like it

I love K2. My problem is the intricated schema used to put the pictures. There are no "picture" column in the "k2_items" table and the NAME of the picture is md5 crypted. It sucks! I lost an entire day to understand how it works.

The "heritage" scheme of categories is also confuse. after a couple of changes I lost the control and cannot retore the "default" status.

After all, the intricated CSS file make changes hard to do without a "error and atempt" hours expend.
