Apply "rel=nofollow" attribute to all parsed URLs

In the first cooperative move for nearly ten years, the major search engines have unveiled a new indexing command for web authors that they all recognize, one that they hope will help reduce the link and comment spam that plagues many web sites....due to removing the point of doing it in the first place.

The new "nofollow" attribute that can be associated with links was originated as an idea by Google in late 2004 and MSN and Yahoo, as well as major blogging vendors have jumped onboard.

The Nofollow Attribute

The new attribute is called "nofollow" with rel="nofollow" being the format inserted within an anchor tag.
When added to any link, it will effectively serve as a flag to tell the search engines that the link has not been explictly approved by the site owner, and therefore "not follow" it, or not use the referring page's (on your site) Page Rank in any way.

For example, this is how the HTML markup for an ordinary link might look:

<a href="http://www.somedomain.com/page.html">My forums are the best lol lol lol click here!!</a>

This is how the link would look after the nofollow attribute has been added, with the attribute portion shown in bold

<a href="http://www.somedomain.com/page.html" rel="nofollow">My forums are the best lol lol lol click here!!</a>

Once added, the search engines supporting the attribute will understand that the link has not been approved by the site owner.

Think of it as a way to flag to them, "I didn't post this link -- someone else did, don't associate me with it."

The site that is being linked to will gain nothing from the link, so the whole point of doing it in the first place is removed.

This will affect URLs in posts, as well as signatures...anything that goes through the bbcodeparse function as far as I can tell/guess, and will work recursively, or whatever the word is that means 'it will affect all existing posts and signatures'...or it did for me anyway.

To change the conditional number of posts, alter

PHP Code:

OR $post['posts'] > 50) 


to whatever you like.

I can't see how this could be done as a plugin, but if anyone wants to point out how, that would be nicer....YAY Kirby!

Now all you need to do is unzip the attached file, upload the plugin using your Admin CP - Plugin System - Plugin Manager!

Relax, safe in the knowledge that spammers linking from your site are doing so for no reason whatsoever.

To remove the old version:

File to modify: 1

1/ Open your includes/class_bbcode.php file

Find:

PHP Code:

        // standard URL hyperlink
        //return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";

        global $post;

if (is_member_of($post, 6) //Admins are exempt
OR is_member_of($post, 5) //Mods are exempt
OR is_member_of($post, 7) //SuperMods are exempt
OR $post['posts'] > 50) // People with over 50 posts are exempt
    {
    // standard URL hyperlink
    return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
    }
    else
    {
     return "<a href=\"$rightlink\" rel=\"nofollow\" target=\"_blank\">$text</a>";
    }
    } 


Replace with:

PHP Code:

// standard URL hyperlink
        return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
    } 


2/ Save and Upload.

Me too !

Given that this has been asked for many times, and I have no idea how, I wish you and everyone else the best of luck in working out a method of determining whether a link is internal or external.

Again, for clarity: I have no idea how to achieve this easily.

[kall]

No idea sorry.

If anyone can, by all means, please tell me.

A link which has this string in it:$variable where $variable is http://www.myforum.com/

Using 3.6+ the plugin works fine until a user reaches 1000 posts and then it starts applying the nofollow to their posts. We've had to create a special group and exempt them as a work around. Is anyone aware of a reason the nofollow would kick back in after 1000 posts?

[jimbocook]

At SEOrefugee.com, we had a problem with this plugin inserting the nofollow tags when a user passed the 1,000 post mark. The problem was a comma inserted into the number of posts (e.g. 1,000). We fixed it by changing this line in the plug in:

        if (is_member_of($post, 5, 6, 7) OR $post['posts'] > 50)

to this (which strips the unwanted comma from the post count):

        if (!(is_member_of($post, 5, 6, 7)===FALSE) || str_replace(",","",$post['posts']) > 50)

can anybody tell me if this is working on my forum or not? I am viewing page sources for multiple threads but im not really sure where im suppose to look to see the no follow being used....Actually, i dont see it anywhere really..I want it to be applied to everything posted, dont care if your a mod or have over 367423 posts...So i changed the PHP code to this...Not sure if its right or not..

global $post;
        // Excempt Mods+ and Users with mor then 50 Posts
        $parsedurl = $parser->handle_bbcode_url($text, $link);
        if (is_member_of($post, 666) OR $post['posts'] > 5000000)

also, my forum is located at www.obsession2speed.com/forums if somebody could take a look at it for me please.

[2 FN LOW]

when i view the page source of this thread i dont see the no follow code where i believe it should be...

http://www.obsession2speed.com/forum...read.php?t=598

if you go down a lil bit when viewing the source code you will come to my post....I notice the URL post is not phrased with the no follow code...why is this?

[vbl]

in the nofollow_plugins.zip, there is one & to much:

in this line:
function handle_bbcode_url_relnofollow(&$parser, $text, $link)
