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!

I was very excited about this component and I created a new website using K2 only to discover that nothing works as promised. Form an SEO perspective this componenet is a joke, with lots of duplicate URLs created by the search functionality and some modules displaying K2 items. This issue was first reported 2 years ago but no one really cares (google this phrase 'K2 SEO issue - Can it be fixed' for more details).

K2 also has big issues with the cache system. It generates a lot of cache files and you will quickly realize you need extra hosting space. For every image you upload, K2 generates an additional 4 or 5 cache images that take lots of space. Again, this issue is more than 3 years old and no fix or update.

I would strongly recommend against using K2 until these basic issues are fixed.

Owner's reply: K2 creating multiple sizes of an image is not a bug, it's a feature. Furthermore, K2's SEO is far better than more content components' is. Not only can you NOT have duplicate URLs by simply creating a hidden menu item pointing to all of K2 categories (this fixes duplicate URLs which would be normal to have depending on where you're browsing the site), we have also included an Advanced SEF section which can alter the URLs to your liking and even remove the item id creating URLs that only commercial SEF components can - and without the DB overload they bring.

K2, like all good things, needs some time and devotion to learn. If you can't see the benefits of it, then you might as well make a static website. I hear Jekyll is all the rage nowadays (good luck with that).

A poorly documented gem


Posted on 28 December 2013

This extension is brilliant, and it shines even more the longer you work with it. The folks at the support forum is friendly and provides competent help.



The only real downside at the beginning is the documentation. It is something between real bad and simply non-existing. When you come to their document site the very first time you get the impression you hit the wrong link ;) - so hopefully the owner will take care a bit more about that in the future.



The CCK is built upon extra fields. You first define an extra field group and add the wanted fields and their types to it. After that, you assign this group to a category, and all content within this category will inherit the group. This concept helps organizing your additions to the standard Joomla content very efficient.



Unlike other CCKs like ZOO the extra field group is blocked within your content and added on the bottom, so your design capabilities are a bit limited.



The real benefit comes with the carefully integrated database support - you e.g. can easily fetch all articles from any single user, something I felt should be trivial however is found only within K2.



Joomla content, categories and users can be easily transferred to the K2 universe. Unfortunately, there is no integrated import/export tool for/to external data sources. The only import/export tool supporting K2 together with Joomla 3.x I found is Hexdata. It offers great possibilities like importing relations, however its current version has a bug and is not working with K2 at the moment.



K2 comes with its own tag system, that is a bit outdated now that Joola 3.x has arrived. Maybe this hopefully will be updated in the future.



K2 is rock solid and can be used on productive sites without worry. This makes it the first choice over SEBLOD, that appears to be in permanent early beta stage ;)

k2 is by far the best component i ever used. for me it's a must-have for every single site, and function as the basis for all my article creation.



if you have some basic php skills you can use the k2 templating features which gives you endless possibilities for templating and designing your site's articles.



the only thing i don't like about k2 is it's front-end publishing / editing interface, which requires lots of work if you want it to look and feel good for a common user, not to mention RTL. but that's only applies for editing, the content templating itself is actually great on that matter.



recommended.

Owner's reply: The good news is that K2 v3.x will make frontend editing a lot better overall and definitely easier for users.

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


Posted on 22 November 2013

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.
