   I'm creating a theme, but I have a problem with excerpts, I was wondering if I could get some help?

   The theme I'm creating has a Featured Post & a Recent Posts section on index.php. It has nothing to do with categories or most viewed posts or anything like that, it's just different styling on the most recent/1st post while the 2nd & 3rd go under Recent Posts with their own styling.

   I'm using improved_trim_excerpt inside functions.php to elongate the_excerpt to 90 words for the Featured Post & is working fine. (Note: it works in such a way that users don't have to use the Excerpt box on the New Post page. It will automatically grab X number of words from the post & add the [...] on the end.)

   Now, in the Recent Posts Section (the 2nd & 3rd most recent posts) I wanted them to only show about 40 words. Here in lies the problem. I tried using a modified improved_trim_excerpt & set it as improved_trim_excerpt2 with no luck.

   I'm no expert on WP functions and could really use some help on this. If I need to provide more info, let me know.

   in functions.php:
   

   function excerpt_length_featured($length){
     return 90;
   }
   function excerpt_length_recent($length){
     return 40;
   }

   Featured Post:
   

   add_filter('excerpt_length', 'excerpt_length_featured');
   the_excerpt();
   remove_filter('excerpt_length', 'excerpt_length_featured');

   Recent Posts:
   

   add_filter('excerpt_length', 'excerpt_length_recent');
   the_excerpt();
   remove_filter('excerpt_length', 'excerpt_length_recent');

   Thanks got it.

   // Excerpt function for Featured Post
   function featured_post_excerpt($text) {
   	global $post;
   	if ( '' == $text ) {
   		$text = get_the_content('');
   		$text = apply_filters('the_content', $text);
   		$text = str_replace(']]>', ']]>', $text);
   		$text = strip_tags($text, '');
   		$excerpt_length = 100;
   		$words = explode(' ', $text, $excerpt_length + 1);
   		if (count($words)> $excerpt_length) {
   			array_pop($words);
   			array_push($words, ' [...]');
   			$text = implode(' ', $words);
   		}
   	}
   	return $text;
   }
   
   // Excerpt function for Recent Posts
   function recent_post_excerpt($text) {
   	global $post;
   	if ( '' == $text ) {
   		$text = get_the_content('');
   		$text = apply_filters('the_content', $text);
   		$text = str_replace(']]>', ']]>', $text);
   		$text = strip_tags($text, '');
   		$excerpt_length = 30;
   		$words = explode(' ', $text, $excerpt_length + 1);
   		if (count($words)> $excerpt_length) {
   			array_pop($words);
   			array_push($words, ' [...]');
   			$text = implode(' ', $words);
   		}
   	}
   	return $text;
   }
   
   /* ----- Two Loops ----- */
   // Featured Post
   	remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   	add_filter('get_the_excerpt', 'featured_post_excerpt');
   	the_excerpt();
   	remove_filter('get_the_excerpt', 'featured_post_excerpt');
   	add_filter('get_the_excerpt', 'wp_trim_excerpt');
   
   // Recent Posts
   	remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   	add_filter('get_the_excerpt', 'recent_post_excerpt');
   	the_excerpt();
   	remove_filter('get_the_excerpt', 'recent_post_excerpt');
   	add_filter('get_the_excerpt', 'wp_trim_excerpt');
