   Hi,

   i'm a beginner at PHP, and i try to display a specific post on the footer.
   i use this PHP code :
   

   <?php
   $post_id = 67;
   $specific_post = get_post($post_id);
   echo $specific_post -> post_content;

   it work good, but i want the "more" tag... i was unable to find a solution... but i think it's very easy... i try this one, but don't work :

   <?php
   $post_id = 67;
   $specific_post = get_post($post_id);
   echo $specific_post -> the_content('more');

   try it with this:
   

   <?php
   $post_id = 67;
   $specific_post = get_posts('include='.$post_id);
   setup_postdata($specific_post[0]);
   the_content('Read the rest of this entry &raquo;');
   ?>

   It works on my testserver. Are you sure you have the right ID (67)?

   be careful, because i'm talking about the content of a PAGE, not a post...
   it seems different ( i don't know why..)

   <?php
   $post_id = 67;
   $specific_post = get_pages('include='.$post_id);
   setup_postdata($specific_post[0]);
   the_content('Read the rest of this entry &raquo;');

   I'm not sure what you mean. Did you split a single post up into different web pages by typing <!--nextpage--> in your post?

    in fact, this is the background of my problem :

    i make a website with wordpress.
    on the footer, i have a little "ABOUT" section (i create an "ABOUT" page), but i want just the beginning (around 3 lines) + a "read more" link.

    when people click on the "read more" link, i want to go to the main "ABOUT" page...

    hope u understand !!
    thanks in advance,

    Ok, I changed the code a little bit:
    

    <?php
      $post_id = 67;
      $specific_post = get_pages('include='.$post_id);
      $content_more =false;
      $html = '';
      $excerpt_length = 40;
      $content = $specific_post[0]->post_content;
      $content = strip_shortcodes($content);
      $content = str_replace(']]>', ']]>', $content);
      $content = strip_tags($content);
      $excerpt = explode(' ', $content);
      if (count($excerpt) > $excerpt_length) {
    	 $excerpt = implode(' ', array_slice($excerpt, 0, $excerpt_length)) . '...';
    	 $content_more = true;
    	} else { $excerpt = $content; }
      if($content_more){
      	$html .= $excerpt;
        $html .= ' <a href="' . get_permalink($post_id) . '" title="Read more about: '.$specific_post[0]->post_title .'">Read more</a>';
    	} else {
    		$html .= $excerpt;
    	}
    	$excerpt = apply_filters('the_content', $html);
    	echo $excerpt;
    ?>

    Change $excerpt_length = 40; to make the excerpt longer or shorter
