   I'm using the Arthemia theme and have posts displayed in the Featured section.
   However, I only get to see the Post title and date. Adding <?php the_excerpt(); ?> to index.php also didn't do the trick, this text was too long.
   How can I just display the first sentence of a post on my homepage?

   putting this code in your theme's functions.php file will limit the length of the_excerpt() to 20 characters. You can adjust 20 to whatever you want.

   <?php
   // Add custom excerpt length
   function custom_excerpt_length($length) {
     return 20;
   }
   add_filter('excerpt_length', 'custom_excerpt_length');
   ?>

   Thanks for the comment, but inserting this gives an error.

   This is the current code in function.php;

   remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   add_filter('get_the_excerpt', 'custom_trim_excerpt');
   
   remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   add_filter('get_the_excerpt', 'custom_trim_excerpt');
   
   function custom_trim_excerpt($text) { // Fakes an excerpt if needed
   global $post;
   	if ( '' == $text ) {
   		$text = get_the_content('');
   
   		$text = strip_shortcodes( $text );
   
   		$text = apply_filters('the_content', $text);
   		$text = str_replace(']]>', ']]>', $text);
   		$text = strip_tags($text);
   		$excerpt_length = apply_filters('excerpt_length', 90);
   		$words = explode(' ', $text, $excerpt_length + 1);
   		if (count($words) > $excerpt_length) {
   			array_pop($words);
   			array_push($words, '...');
   			$text = implode(' ', $words);
   		}
   	}
   	return $text;
   }

   I just want to limit the excerpt length for the featured posts, the limitation should not apply to all other posts using excerpts as well...

   Any idea?

   This should only be there once. From what you posted it is there twice

   remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   add_filter('get_the_excerpt', 'custom_trim_excerpt');

   How do you know when a post is a featured post? Is it in a featured category? If it is, what is the category id # of that category on your site? From that the function can be modified to only create an excerpt in some conditions.

   Yes, the posts are in a category; ID 93.
   What should the code be and what do I need to delete or replace?

   Thanks so much for your quick repsonse!

   The way I am setting this up you will not be able to have excerpts anyplace on your site other than on featured posts. If that is not what you want let me know how it should work.

   I didn't test the small change I made. Try it.

   You already have these two lines at the top - keep them
   

   remove_filter('get_the_excerpt', 'wp_trim_excerpt');
   add_filter('get_the_excerpt', 'custom_trim_excerpt');

   replace the existing function with this
   

   function custom_trim_excerpt($text) { // Fakes an excerpt if needed
   global $post;
   	if ( '' == $text && in_category(93) ) {
   		$text = get_the_content('');
   
   		$text = strip_shortcodes( $text );
   
   		$text = apply_filters('the_content', $text);
   		$text = str_replace(']]>', ']]>', $text);
   		$text = strip_tags($text);
   		$excerpt_length = apply_filters('excerpt_length', 90);
   		$words = explode(' ', $text, $excerpt_length + 1);
   		if (count($words) > $excerpt_length) {
   			array_pop($words);
   			array_push($words, '...');
   			$text = implode(' ', $words);
   		}
   	}
   	return $text;
   }

   If it doesn't work try changing the IF line to
   if ( '' == $text && in_category(93, $post->ID) ) {

   Thanks!

   What I really would like to have is:
   Featured posts: 50 characters (20 words, taken from original post
   Posts on homepage or on categorye page: use excerpt settings

   Does your code provide this?

   What I sent is the code you posted with a few changes to limit where it is applied.

   The number 90 in the code is the number of characters. Change it to whatever you want.
