Adding no follow for links in wp comments

Don't Follow MeOne of my senior brother just asked me, how to add no follow rel for comments in wordpress. May be there is plugin for this. Look to my code 🙂
How to use:
1.Open the functions.php file in ur current theme and put these code within php tags.

What it will do:
1. Will add ‘no follow’ as rel in url , if comment contains any url.
2. Will ad ‘external’ as rel in url , if comment contains any url.
3. Will add target=”_blank” in comment author’s url so that their web url open’s in new window/new tab as in browser settings
4. Will add target=”_blank” to url, if comment contains any url
5. Wp adds ‘no follow’, ‘external’ rel in comment author’s url by default. So we don’t need to add this 😛

Tips:
1.If possible upgrade to wp2.8.2

      function nofollow($text) {
	        $text = preg_replace('/<a /i','<a rel="nofollow external" ',$text);
	        $text = preg_replace('/<a /i','<a target="_blank" ',$text);
	        return $text;
    }
    function targetblank($text){
    		$text = preg_replace('/<a /i','<a target="_blank" ',$text);
	        return $text;
    }

    add_filter('comment_text', 'nofollow');
    add_filter('get_comment_author_link','targetblank');

any question ask me 🙂
p.s.: post image is just for fun 😛

  1. Nofollow and dofollow are two important topic for page rank. If in ur website, dofollow links are kept, your page rank will be affected for that dofollow
