$10
Function to truncate comment text on home page.

I am showing most recent comments on the home page using:

<?php $_comments=get_comments('number=5'); ?>

<?php foreach($_comments as $comm): ?>

<?php  echo $comm->comment_content; ?>

I need some way to limit, truncate the comment content after a certain (60-70) amount of characters.

This question has been answered.

  Hey Micheal,
  
  This works great... Is it possible to have the "..." link to the actual comment without much work? :)

  Something like this might work for ya:
  
  function mfields_shorten( $string, $crop = 23, $trail = '...') {
  global $comment;
  $string = strip_tags( $string );
  $string = trim( $string );
  $string = html_entity_decode( $string, ENT_QUOTES, 'UTF-8' );
  $string = rtrim( $string, '-' );
  $crop = intval( $crop );
  $trail = '<a href="' . get_comment_link( $comment ) . '">' . $trail . '</a>'
  return ( strlen( $string ) > $crop ) ? substr_replace( $string, $trail, $crop ) : $string;
  }

  Actually, there was an error there...
```
function mfields_shorten( $string, $crop = 23, $trail = '...') {	

	global $comment;

	$string = strip_tags( $string );

	$string = trim( $string );

	$string = html_entity_decode( $string, ENT_QUOTES, 'UTF-8' );

	$string = rtrim( $string, '-' );

	$crop = intval( $crop );

	$trail = '<a href="' . get_comment_link( $comment ) . '">' . $trail . '</a>';

	return ( strlen( $string ) > $crop ) ? substr_replace( $string, $trail, $crop ) : $string;

}

  Chris, this just gets rid of the whole text. I would like to truncate it after a certain amount of characters.

Hey Svilen,

Thanks but this doesn't work.

Here is the clean code:

<?php

			function cut_comment($str, $comment_link, $len = "65") {

				if(function_exists('mb_strlen')) {

					return mb_strlen($str,'UTF-8')<$len ? $str : (mb_substr($str,0,$len-1,'UTF-8').'<a href="'.$comment_link.'">...</a>');

				}

				if( function_exists('iconv_strlen') ) {

					return iconv_strlen($str,'UTF-8')<$len ? $str : (iconv_substr($str,0,$len-1,'UTF-8').'<a href="'.$comment_link.'">...</a>');

				}

				return strlen($str)<2*$len ? $str : (substr($str,0,2*$len-2).'<a href="'.$comment_link.'">...</a>');

			}

			$_comments=get_comments('number=5');

			foreach($_comments as $comm):

				$comment_url = get_comment_link($comm->comment_ID );

				echo cut_comment($comm->comment_content, $comment_url, 70); 

			endforeach;

Try this:

$_comments = get_comments('number=5');



foreach($_comments as $comm) {

    $comment_link = get_comment_link($comm->comment_ID);

    $comment_content = strip_tags($comm->comment_content);

    $comment_content = substr($comment_content, 0, 60 );

    echo $comment_content.'<a href="'.$comment_link.'">...</a><br />';

};
