B2J News Loader for K2 module is one of the first modules produced by Bang2Joom. This module is Based on K2 component. K2 was constructed as a replacement of the default article system in Joomla!.

You can install it like any Joomla! extension,import your articles from the default Joomla! article system and get a host of new features for your current content.If you are not familiar with K2 component,please check K2 Documentation. ,

From the first sight it may seem to be a very simple module, a module that fetches K2 items, and renders them in particular design. But what makes this module unique,is the fact that it uses AJAX technology to fetch more items. The module shows some number of items at the page load, then, when users want to see more items, the module loads more items via AJAX. This provides the module with an ability to show more items, without increasing the page loading time.

The B2J News Loader module has many configurable options, which can help you to get the most suitable look for your website. Note, that the module is also able to create its cache for K2 item's images, with the size specified by user.






Note, that every folder contains an index.html file. Besides, I skipped all the images containing in images folder to keep the list short and to the point.

Lets start from the files in main folder.

mod_b2j_k2_news_loader.xml is the xml file of the module. It has information about the module itself and the back-end fields.

mod_b2j_k2_news_loader.php is the starting point file of the module. It calls the tmpl/default.php file, which is the view file.mod_b2j_k2_news_loader.php file is also responsible for AJAX calls, so it is being called again and again when module need to fetch more items via AJAX.

helper_parameters.php stores all the back-end field values into variables, which are later used in tmpl/default.php.

helper.php is helper file for the module. This files contains the functionality for image resizing, caching and text manipulations(like limiting introtext).

admin folder is for the backend part of the module.

admin/elements/b2jupdate.php is responsible for updates. If new updates are available, it notifies the user about it.

admin/elements/b2jhidden.php is helper file for back-end, it includes all the necessary files.

admin/elements/b2jmargin.php is a field type, for specifying image margins. It is used in the back-end.

admin/elements/b2jgeneratecache.php and admin/elements/generatecache.php files are responsible for generating cache from the back-end based on some parameters.

tmpl/default.php is the main view file, which renders the module. It has the view HTML and some javascript for handling the AJAX calls.

tmpl/js/b2j_scrollbar.js is a jquery library for adding a scrollbar to views.

tmpl/css/b2j_k2_news_loader.css and tmpl/css/b2j_k2_news_loader_metro.css are the currently available presets. More presets will be available gradually. Note, that when choosing a preset from the back-end,the corresponding css is loaded.


The installation process of B2J News Loader for K2 is as easy as any standard Joomla! module, but there are few steps, which need to be done before the module installation. The first step is to install the K2 component. Please visit to download it. After you are done with its installation, you need to create a K2 category, and add some items in it. If you are not familiar with K2 component, check K2 Documentation. The process is almost the same as Joomla! native article management.

B2J News Loader is going to use those items to show them in its view.

Let's take look at the module back-end now. B2J News Loader currently has 5 sections to be configured.

Basic Settings
Ordering of Info Block Parts
Block Settings

Basic Settings

Generate Thumbnails - This button creates cache for the module. It is very important, that when you change something concerning to a thumbnail, you need to recreate the cache after saving the changes. Make sure that K2 Category, Thumbnail Width, Thumbnail Height and Max Number of Items are set, otherwise the caching will not work. If your cache is not being recreated, just remove the cached files manually, then click on Recreate Thumbnails again. The cached images for the current module are in mod_b2j_k2_news_loader/cache/m***, where *** is the id of your module. Please note that you need to save the back-end changes, and ONLY after saving use Recreate Thumbnails button.

When I click on Generate Thumbnails, the cache is not refreshed, what do I do.
Probably there is something wrong with permissions. The module is able to create cache, but it can't remove the old cache files first. All you need to do is to remove cached images manually. Go to mod_b2j_k2_news_loader/cache/m***, where *** is the id of your module, and remove the files there,and try Generate Thumbnails again.

What settings do I use to have to display the full month name, not just the abbreviation (Jun) in the module frontend. I have 'M d Y' now.
The date format is done by PHP date functionSo in this case you should have 'F d Y'
