wp有没有将首页文章标题自动截短的插件

代码:

function excerpt(){
	echo $this->get_excerpt();
	}
			
function get_excerpt(){
	global $post;
				
	$max_length = 20; // Maximum words.
				
	if ($post->post_excerpt) return $post->post_excerpt;
				
	if( strpos($post->post_title) ) { 
    $temp_ex = explode($post->post_content, 2);
    $excerpt =  $temp_ex[0];
    } 
	else {
    $temp_ex = explode(' ', $post->post_title);  
	$length = count($temp_ex) < $max_length ? count($temp_ex) : $max_length;
	for ($i=0; $i<$length; $i++) $excerpt .= $temp_ex[$i] . ' ';
    }
        
	$excerpt = balanceTags($excerpt);
	$excerpt = apply_filters('the_excerpt', $excerpt);
				
	return $excerpt;
				
	}
