WordPress自定义函数控制文章标题长度

代码如下:

function TruncateTitle($max_length) { 
$title_str = get_the_title(); 
if (mb_strlen($title_str,'utf-8') > $max_length ) { 
$title_str = mb_substr($title_str,0,$max_length,'utf-8').'…'; 
}
return $title_str; 
}

代码如下:

<a href=”<?php the_permalink() ?>” target=”_blank”><?php echo TruncateTitle(14); ?></a>
