Try playing with this section of code ;)

	/**
	 * Load data from Request form fields.
	 *
	 * @return boolean true if loaded data seems valid.
	 */
	function load_from_request()
	{
		global $DB;

		parent::load_from_Request();

		// Check url name
		if( param_string_not_empty( 'cat_urlname', T_('Please enter an urlname.') ) )
		{
			$this->set_from_Request( 'urlname' );
			if( ! preg_match( '|^[A-Za-z0-9\-]+$|', $this->urlname )
					|| preg_match( '|^[A-Za-z][0-9]*$|', $this->urlname ) ) // This is to prevent conflict with things such as week number
			{
				param_error( 'cat_urlname', T_('The url name is invalid.') );
			}
			else
			{
    		if( Chapter::urlname_exists( $this->urlname, $this->ID ) )
				{ // urlname is already in use
					param_error( 'cat_urlname', T_('This URL name is already in use by another category. Please choose another name.') );
				}
			}
		}

		return ! param_errors_detected();
	}

I tried to add there $this->set_from_Request( 'description' ) but the object has empty properties.

'description' => NULL, 'longdesc' => NULL,

p.s. I already changed this function

function Chapter( $db_row = NULL, $subset_ID = NULL )
{
	// Call parent constructor:
	parent::GenericCategory( 'T_categories', 'cat_', 'cat_ID', $db_row );

	if( is_null($db_row) )
	{	// We are creating an object here:
		$this->set( 'blog_ID', $subset_ID );
		
	}
	else
	{	// Wa are loading an object:
		$this->blog_ID = $db_row->cat_blog_ID;
		$this->urlname = $db_row->cat_urlname;
		$this->description = $db_row->cat_description;
		$this->longdesc = $db_row->cat_longdesc;
		$this->icon = $db_row->cat_icon;
	}
}

Do you think it would be easier to make a simple sql query and wait for a new release :roll: ?

Probably :p

Ok, fine I'll post the hack to update those new fields

This code is for update process only.

inc/chapters/chapters.ctrl.php starting line 220

// LOAD FORM DATA:
if( $edited_GenericCategory->load_from_Request() )
{	// We could load data from form without errors:
	// Update in DB:
	
	$sql = 'UPDATE T_categories SET
				cat_description = '.$DB->quote($_POST['cat_description']).',
				cat_longdesc = '.$DB->quote($_POST['cat_longdesc']).',
				cat_icon = '.$DB->quote($_POST['cat_icon']).'
			WHERE cat_ID = '.get_param('cat_ID');
	
	$success1 = $edited_GenericCategory->dbupdate();
	$success2 = $DB->query($sql);
	
	if( $success1 !== false || $success2 !== false )
	{
		$Messages->add( T_('Element updated.'), 'success' ); //ToDO change htis
	}
	// Add the ID of the updated element to the result fadeout
	$result_fadeout[$edited_GenericCategory->dbIDname][] = $edited_GenericCategory->ID;
	$action = 'list';
}
