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, Gorillaz.com, 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

Good Content Com


Posted on 02 August 2013

I have used K2 for a long time, this is excellent com. Next time I hope K2 Team documentation of K2 version.



Thanks


I've using k2 for several years for my projects. This is the first extension I used to add after installing joomla. The content templating is easy and there are lot of useful functions as commenting and rating system, gallery and extra fields for your items. There are tons of useful extension for it.



BUT THERE IS ONE VERY SERIOUS PROBLEM!!!



If you create catalog system with lots of extra fields (40+) it will dramatically slow down your site in category view. Even if you create custom template to show only few extra fields in category view. The reason of this (I think) is the way extra fields are stored in the database. All of the extra fileds for an item is stored in one database field. If you display for example only 5 extrafields from 40 for each item in category view the system will looping through all extra fields because they are stored in one database field. I tried to get help from developers but there is no answer and no solution. The extra fields would give the real power of a CCK but this way it unusable for items with lots of properties. I hope this will be fixed if so this will be the number one extension.


The extension is almost perfect, if I would only find the way to auto-archive old items, i.e. Items more than 12 months old.

Owner's reply: K2 doesn't have (and doesn't need) an auto-archive feature. The "archive" feature was originally implemented in Joomla!'s default article system as a way to lighten up the database from old articles. K2 is better optimized and so it doesn't need that.

Additionally, you can use the K2 Tools module to list K2 content by month created, similar to a blog archive, as it's usually found in such platforms.

K2 seems stable, looks good, tons of capabilities but I couldn't get past a simple problem. And worse yet, except for a few instances, there remains many users counting myself that have never found a solution and are simply being ignored on the support forums. K2's own registration system seems to conflict with Joomla's own default reCaptcha system. I and others have followed every single piece of advise available, yet the issue remains. So, you end-up with two choices: turn off reCaptcha (not acceptable), or uninstall K2 and go with another system to manage your advanced content ... huge disappointment!!! ... no doubt a dev will respond to this and tell me how much I didn't do.

Owner's reply: Your question is probably answered on the forum already, as it's too simple. Either disable the Joomla! reCaptcha plugin and enable K2's built in or the opposite. Both will work. If they didn't, then maybe some other system or user plugin is to blame. If I were you, I'd disable Joomla! reCaptcha, because K2's can also be hooked up with StopForumSpam, in which case, real human spammers are 95% of the times caught and blocked.

Mixed feelings


Posted on 13 July 2013

according to the description "out of the box" I was quiet surprised how much i had to learn about php and css. I realy put great effort and time in tutorials and learning how to style. Unfortunately I ended up in the lots of forums trying to find ways how to tweak it and make it work in general. Beside the conflicts with images and a responsive template the issue with item view in the subcategory listings listings (that were showing in the category) - and the only solution to get into the php file again ....gave me the rest ...gave up.

Conclusion: if you have knowledge in coding and css ... should be a great component ... for someone who wants a solution out of the box ...stick with joomla itself.

Owner's reply: If you thought K2 was difficult, wait till you try the default Joomla! article system (com_content) templating. We get lots of Joomla! newbies digging into K2 first, instead of com_content and believe K2 is hard to work with. It's not hard, it's how Joomla!'s templating works and these people soon find out when they use com_content. K2's templating is simpler and easier to work with. Most of the times you won't even need to touch the PHP code blocks. Just switch off any elements you don't want per category or even per item. Want to move things around (re-order the item elements)? Just move the marked PHP blocks. Can't get any simpler than that and com_content is far more difficult to work with. That's the reason why we built K2 in the first place...

A final note. Don't expect to get into a proper CMS like Joomla! and NOT learn a few things on HTML, CSS, JS or even PHP. Try modifying a WordPress theme. Joomla! templating will then seem like a walk in the part. Try Drupal. Hell is colder that Drupal theming...

If you don't learn the basics of HTML, CSS, JS & PHP, you'll always feel stuck. And then the only solutions you'll end up with are Tumblr or Blogspot. Even those may require HTML editing as well sometimes... But they'll only be a blog and nothing more.

Can't/don't want to learn the web's languages? Then hire a pro developer.

Things are most of the times simpler than we think.

Simple, Great, Works...

I am building websites using K2 for blogging, news, magazine and product portfolio sites for some time.



Template override and creating new templates per categories are absolutely lights my my.



A Note To Developers : Multi image, Multi Category and Multi extrafiels would be great move for K2 in the future.



and if only you can create thumbs using crop and zoom for equal photos in category blog.


I love K2 and have used it for many years without any issues. However, I have run into my first problem and decided to register on the K2 forum. I received the activation email and clicked on the link to activate the accout, but I cannot get in. The site reports that my account is blocked or has not been activated. Hopefully someone can assist me with this because without support, I am dead in the water with this issue.

Owner's reply: The K2 website is one of the most popular in the Joomla! community and thus it gets hit by lots of spammers.

Because we prefer to provide help to K2 users and not chase spam posts all the time (we're talking about human spam here, not bots et al), we recently had to take additional measures by deploying anti-spam checks using the StopForumSpam.com global database.

This means that from the thousand logins and signups we get per month, from time to time, legitimate users may get caught on as well.

So please either email us (use the site's contact forum) or send a tweet to us at @k2devs so we can whitelist and enable your registration.

If you tried to login using a social network account and got caught by our anti-spam system, try creating a standard Joomla! account. Or vise versa.

Excellent

This extension is installed in every single Joomla! Website that I ever delivered, because it's so elastic and complete that it makes it fundamental.


Works perfect. Just download this component and you don't need anything else.

Great!!!!

The templates are so perfect. If you are designer or make custom templates you will know what I'm talking about.



Everything has a class and ID, you can have multiple templates, overrides. Get extrafields where you want...



Best extensions!

*** New version 3 released, now compatible with Joomla! 1.5 to 3.x *** Adding image galleries inside your Joomla! articles is now super-easy and simple, using the magical "Simple Image Gallery" plugin for Joomla!. The plugin can turn any folder of images located inside your Joomla! website into a grid-style image gallery with cool lightbox previews. And all that using a simple plugin tag like . So for example, if we have a folder called "mytriptoParis" located in images/stories/mytriptoParis, then we can create our gallery by simply entering the tag into some Joomla! article. The galleries created are presented as a grid of image thumbnails. When your visitors click on a thumbnail, they see the original image in a lightbox popup. The thumbnails are generated and cached using PHP for better results. So let's briefly see what are the main advantages of using Simple Image Gallery: a) You don't need to have an additional gallery component to display a few images, b) you don't need to tell your visitors "to see our photos from Paris click here" and c) you focus more on content writing and less on administering the images! The plugin is ideal for news portals wanting to display some product images, for example, inside their articles. Or for people who quickly wanna show their summer vacation pictures. With Simple Image Gallery, you can have as many galleries as you want inside each article. Please note that if you want to create a gallery from a subfolder located inside your "image gallery root folder", simply adjust the plugin syntax to reflect the remaining path (after your set "root folder"),. Make sure you write the path to your target folder without any slashes at the beginning or the end of your path. You can see a demo of the plugin here: http://demo.joomlaworks.net/simple-image-gallery Simple Image Gallery is a Joomla! plugin developed by JoomlaWorks, released under the GNU General Public License.

Adding RSS/Atom syndicated content inside your Joomla! website is now super-easy and simple with the 'Simple RSS Feed Reader' module from JoomlaWorks. All you have to do is add a few feeds to the module parameters, publish the module in some position and that's it! You can even publish multiple feeds at the same time (meaning in the same module instance) and have them display combined! The "Simple RSS Feed Reader" module is based on the same feed parsing engine that powers JoomlaReader.com, the most popular Joomla! news aggregator in the Joomla! Community. The feeds are stored inside your Joomla! site's cache folder and refreshed in a specific time interval, which you set in the module's parameters. This feed cache is different to Joomla!'s cache, as you may need to have your site refreshed every 5 minutes, but have the feeds the module retrieves stored longer than 5 minutes. NOTABLE FEATURES one input box for feeds enables you to add unlimited feeds per module instance combine multiple feeds into one output list show or hide the first image inside each feed content extract and resize remote images for more layout control - we use Mobify's world class image resizing service for fast loading times and without stressing your server additional content options include pre-text, post-text and a custom link option at the bottom of the feeds block MVC templating is now standard, module comes pre-packed with 2 generic templates that will fit most sites - they also serve as a great starting point if you want to create your own one input box for feeds enables you to add unlimited sources to your module (previously limited to 20 feeds only per module instance). option to redirect all external feed links through your site's domain (slighly improves your SEO). GETTING STARTED After you install the module, add one or more feed sources in the related box under "Fetch Options" and simply adjust the "Feed Content Options" in the module parameters. Then publish into some module position. STYLING The module installs with 2 generic templates (default and compact), which should be sufficient for most websites. If you want more control, you can simply override both the generated HTML and CSS, using MVC template overrides within your Joomla! template. Or you can create new folders with new module templates inside your template's /html/modjwsrfr/ folder and just select the new ones in the module's parameters. The compact template is inspired by: http://joomlareader.com DEMO Demo for "default" sub-template: http://demo.joomlaworks.net (right column)
