Create a module in Joomla
First module will be registered in a database. Tables that will do this is jos_modules
(code below will change the prefix of the database - in this tutorial will keep the code below!).
We will start this little tutorial by creating a module that displays the latest headlines Posted articles.
This module will mod_lastarticle name.
To begin you will need to register the module in the database. To do this open phpMyAdmin, select the desired database, select the table
jos_modules and SQL tab add the following code:
INSERT INTO jos_modules (title, ordering, position, published, module, showtitle, params)
VALUES ('Last article', 1, 'left', 1, 'mod_lastarticle', 1, '');
At this point the module will not appear on the site even if in the records in the data set published = 1.
We enter the admin panel, Extensions -> Module Manager and will open new module created (mod_lastarticle). When we set Assigment Menu option
All and will save the module.
At this point we can check it on the first page display. If all went well before you see the module title set in the database
(Last article) in the "left" the site, the first position.
Next we create a new folder in modules directory called mod_lastarticle. In this directory we will create a file mod_lastarticle.php.
In this file we will add a header with license and we will check if the file is called by joomla
<?php
/**
* @version $Id: mod_login.php 10381 2008-06-01 03:35:53Z pasamio $
* @package Joomla

defined('_JEXEC') or die('Restricted access');
The next step will be a database query to be returned to us last items added records in the database.
$db =& JFactory::getDBO(); $query = "SELECT `title` FROM #__content ORDER BY `created` DESC LIMIT 0,5"; $db->setQuery ( $query ); $rows = $db->loadObjectList(); foreach ($rows as $row) { $query = "SELECT `alias` from #__categories WHERE `id` = '".$row->catid."'"; $db->setQuery ( $query ); $rezult = $db->loadResult(); $link = JRoute::_('index.php?option=com_content&view=article&id='.$row->id.':'.$row->alias.'&catid='.$row->catid.':'.$rezult.'&Itemid=50'); echo '<a href="'.$link.'">'.$row->title.'</a><br />'; } ?>
At this time we will be this way last retunate Posted 5 items (including link to them).
Then you have to create a new file called mod_lastarticle.xml. In this file we add the following code:
<?xml version="1.0" encoding="utf-8"?> <install type="module" version="1.5.0"> <name>Last article</name> <author>Numele tau aici</author> <creationDate>Noiembrie 2009</creationDate> <copyright>Copyright (C) </copyright> <license>http://www.gnu.org/licenses/gpl-2.0.html GNU/GPL</license> <authorEmail>

At this point you can archive directory mod_lastarticle and it can provide to other users to use.
To be continued ...
