hudson2001 on "Multiple category selection hack?"

Okay, I found the two PHP files used for the plugin. Can these be modified to work on WordPress?

Here is one of the files content:

<?php
/**
 * This file implements the Lottery Plugin
 *
 *
 */
if( !defined( 'EVO_MAIN_INIT' ) ) die( 'Please, do not access this page directly.' );

/**
 * Random Picture Plugin Widget
 *
 * This widget displays a randomly chosen lottery balls in the sidebar or in another container
 *
 * @package plugins
 */
class after_categories_plugin extends Plugin
{
	/**
	* Variables below MUST be overriden by plugin implementations,
	* either in the subclass declaration or in the subclass constructor.
	*/
	var $name = 'After Categories';
	var $code = 'submit2';
	var $priority = 99;
	var $version = '0.1';
	var $author = 'Foppe Hemminga';
	var $help_url = 'http://www.blog.hemminga.net/';
	var $group = 'Amazing Discoveries';
	var $debug_this_widget = 0;

	function PluginInit( & $params )
	{
		$this->short_desc = $this->T_( 'This widget creates a submit button for the Categories widget.' );
		$this->long_desc = $this->T_( 'This widget must be placed in the same container after the Catgories widget.' );
	}

	/**
	*
	* Settings for this widget
	* The current_draw and date_current_draw are hidden settings (not adjustable by user)
	* needed to get the settings in the database.
	* This is a workaround for a real database table structure.
	*
	*/
	function GetDefaultSettings()
	{
		return array(

			);
	}

	/**
	* Get definitions for widget specific editable params
	*
	* @see Plugin::GetDefaultSettings()
	* @param local params like 'for_editing' Arrow true
	*/
	function get_widget_param_definitions( $params )
	{
		return array(

			);
	}

	/**
	* Sets all the display parameters
	* these will either be the default display params
	* or the widget display params if it's in a container
	*
	* @param array $params
	*/
	function init_display( $params = array() )
	{
		$temp = $this->get_widget_param_definitions( array() );
		$full_params = array();
		foreach( $temp as $setting => $values )
			$full_params[ $setting ] = ( isset( $params[ $setting ] ) ? $params[ $setting ] : $this->Settings->get( $setting ) );
		foreach( $params as $param => $value )
			$full_params[ $param ] = $value;
		return $full_params;
	}

	function SkinTag( $params )
	{
		// If the widget params aren't set up, using the plugin defaults
		$params = $this->init_display( $params );
		$this->showblock( $params );

		return true;
	}

	/**
	*
	* Where it all comes together
	*
	*/
	function showblock( $params )
	{
		?>
			<div class="bSideItem widget_core_coll_category_list">
				<input name="submit" class="submit" value="Get selection" type="submit">
				</form>
			</div>
		<?php
	}
}
