Help with the excerpet -.-

[gsn]

Hi guys, I’m trying to modify a widget in order to show image, title and excerpt. I’ve successfull done everything, except for the excerpt ( :P). What I have to do?

Thanks a lot!

[php]<?php

/* Register Widget

  function register_top_story() {
  register_widget( ‘top_story’ );

  /* Constructor */
  function top_story() {
  	$widget_ops = array( 'classname' => 'top_story', 'description' => 'A widget to display your recent posts and can be sort by category with thumbnail or withour thumbnail.' );
  	$this->WP_Widget( 'top_story', 'DARDANIA Top Story)', $widget_ops);
  	
  }
  
  /* Widget display */
  function widget( $args, $instance ) {
  	extract( $args );
  
  	$post_id = $instance['posts_name'];
  	
  	$title = apply_filters('widget_title', $instance['title']);		
  	if ( empty($title) ) 
  			$title = false;
  
  	echo '<div class="widget top-story">';
  		
  
  	
  
  	
  	if ( $title )
  	echo $before_title . $title . $after_title . "\n"; ?> 
  		<div>
  				
  		<?php $post = get_post( $post_id ); ?>
