Mark Internal Links - Need HELP

[PWaddict]

Hello,

I would like to automatically add a class to every internal link.

The below module adds a class to every external link. Can someone modify it to do the same thing for internal links only?

Thanks in advance.

class TextformatterMarkExternalLinks extends Textformatter {

	public static function getModuleInfo() {
		return array(
			'title' => 'Mark External Links', 
			'version' => 102, 
			'summary' => "Adds a class='external' and a rel='nofollow' to every external link."
		); 
	}

	public function format(&$str) {
		$str = preg_replace_callback('%<(a\s[^>]+)>%isU', array($this,"mark_external"), $str);
	}
	
	function mark_external($match) { 
	    list($original, $tag) = $match;  

	    $blog_url = 'http://'.$this->config->httpHost.$this->config->urls->root;
	
	    if(strpos($tag, "nofollow")) {
	        return $original;
	    } elseif(!strpos($tag, 'http')) {
	    	 return $original;
	    } elseif(strpos($tag, $blog_url)) {
	    	 return $original;
	    } else {
	        return "<$tag rel='nofollow' class='external'>";
	    }
	}

}
?>

First things first: what do you need this for? If it's a style-related thing use attribute selectors instead. Basically the same thing goes for JavaScript stuff.

If you really need a server-side solution to this, the polite thing to do would be giving it a try yourself before asking someone to do it for you. That being said, what you are asking for would mean a) checking that the link isn't relative (href="/foo/" or href="index.html") and b) checking that it doesn't point to your own site (href="your-own-site...)

It's really not a very difficult thing to do if you put your mind to it, so why don't you give it a try and if you run into any issues ask help with those?

As you've already found nico's textformatter you could also use a:not(.external) to get all internal links.

Thanks for the replies. LostKobrakai's solution is perfect. So, no need to have a module for that. Maybe this topic should be moved to another category.

@teppo Already tried to do it but without any success. It's very confusing for me, that's why I asked for help. I wanted the class for ajax loading not to style it.

@LostKobrakai Thanks for helping me once again
