   <?php
   $trim_length = 21;  //desired length of text to display
   $custom_field = 'your custom field key here';
   $value = get_post_meta($post->ID, $custom_field, true);
   if ($value) {
     echo '<p>I want to use: ' . rtrim(substr($value,0,$trim_length)) . '...</p>';

   Hi MichaelH,

   I can't seem the get this to work. When I put this in my functions.php file I got an error due to the <?php that's at the beginning. I placed the code exactly like this to not get an error:
   

   $trim_length = 21;  //desired length of text to display
   $custom_field = 'your custom field key here';
   $value = get_post_meta($post->ID, $custom_field, true);
   if ($value) {
     echo '<p>I want to use: ' . rtrim(substr($value,0,$trim_length)) . '...</p>';
   }

   but it still doesn't work.. why am I doing wrong?

   Correction, this is how I placed my code:
   

   $trim_length = 21;  //desired length of text to display
   $custom_field = 'drink description';
   $value = get_post_meta($post->ID, $custom_field, true);
   if ($value) {
     echo '<p>I want to use: ' . rtrim(substr($value,0,$trim_length)) . '...</p>';
   }

   I placed the code in my loop so that it pulls the custom field on every post like so:
   

   <?php
   		$trim_length = 5;  //desired length of text to display
   		$custom_field = 'drink description';
   		$value = get_post_meta($post->ID, $custom_field, true);
   		if ($value) {
   		  echo rtrim(substr($value,0,$trim_length));
   		}
   		?>

   but no dice....
