   Hello guys,

   I'm looking for a way to dynamically truncate the custom fields that appear on my site's homepage.

   I'm using this code:

   <?php $posts = get_posts('numberposts=3&offset=1&category=3'); foreach ($posts as $post): setup_postdata($post); ?>
   
   <a href="<?php the_permalink(); ?>"><?php echo get_post_meta($post->ID, 'titre_propre',true) ?></a>

   "titre_propre" is the personal custom field I'd like to truncate to, let's say, 40 characters.

   Can anybody help me with this, please? That'd be much, much appreciated :)

   Regards,

   kReEsTaL

   Ok, I got it.

   I simply used the fonction spencerp shared in this topic, customizing it by declaring the variable I needed:

   - in functions.php:

   function the_title2($before = '', $after = '', $echo = true, $length = false) {
   global $post;
   $title = get_post_meta($post->ID, 'key_of_your_custom_field',true);
   
   if ( $length && is_numeric($length) ) {
   
   $title = substr( $title, 0, $length );
   }
   
   if ( strlen($title)> 0 ) {
   
   $title = apply_filters('the_title2', $before . $title . $after, $before, $after);
   
   if ( $echo )
   
   echo $title;
   
   else
   
   return $title;
   }
   }

   - in the template where you need to truncate your custom field, simply use:

   <?php the_title2('', '...', true, '40') ?>

   ...where 40 is the number of characters you want to display.

   Yay me! :D
