How can I put 'nofollow' attribute on next_post_link() ??

    Hello there.
    I have a simple, basic navigation on single.php which allows the user to go to the next and previous post through the next_post_link() function.

    The code looks like this:

    <div class="singlepostnavwrap">
<div class="singlepostnav">
<?php previous_post_link('%link', '&laquo; PREV ARTICLE ', TRUE); ?>
</div>

<div class="singlepostnav2">
<?php next_post_link('%link', 'NEXT ARTICLE &raquo;', TRUE); ?>
</div>
</div><!--//SINGLEPOSTNAVWRAP-->

    When this php is run, the html anchors output with a rel=”dofollow”,
    I would simply like to make these links rel=”nofollow” for SEO purposes.

    How can I do this with the php links?

    Thank you so very much for your time.
    I really appreciate it! ??

  • You can do what you want with a filter. Add this either to your functions.php or to single.php:

    function mam_post_link_nofollow ($link) {
     global $mam_set_nofollow;
     if ($mam_set_nofollow) $link = str_replace('dofollow','nofollow',$link);
     return $link;
   }
add_filter('previous_post_link','mam_post_link_nofollow');
add_filter('next_post_link','mam_post_link_nofollow');

    Then set and clear the global $mam_set_nofollow like this:

    <?php $mam_set_nofollow = true; ?>
<div class="singlepostnavwrap">
<div class="singlepostnav">
<?php previous_post_link('%link', '&laquo; PREV ARTICLE ', TRUE); ?>
</div>

<div class="singlepostnav2">
<?php next_post_link('%link', 'NEXT ARTICLE &raquo;', TRUE); ?>
</div>
</div><!--//SINGLEPOSTNAVWRAP-->
<?php $mam_set_nofollow = false; ?>

    Wow thank you so very much vtx.
    that is way beyond what I ever would’ve come up with on my own hahaha.
    Thank you so much for your help .
    butttt… maybe i did something wrong. but it’s not quite working.
    take a look if you’d be so kind: https://dev.bloginity.com/blog/2010/06/01/155/

    here is my functions.php (i added in the code you supplied me):

    <?php

# This theme supports gettext
function theme_init(){
	load_theme_textdomain('Transcript', get_template_directory() . '/languages');
}
add_action ('init', 'theme_init');

# Define Theme Content Wrapper Width
$GLOBALS['content_width'] = 500;

# Define Includes Path */
$gab_includes = TEMPLATEPATH . '/includes/';

#this theme support post thumbnails
add_theme_support('post-thumbnails');

#This theme supports custom navigation
if ( function_exists('wp_nav_menu') ) {
	add_theme_support( 'nav-menus' );
}

# Load theme Javascripts into the wp_head
require_once ($gab_includes . 'theme-js.php');

# Register widget zones
require_once ($gab_includes . 'register-widget-zones.php');

# Theme Functions
require_once ($gab_includes . 'theme-functions.php');

# Theme Plugins
require_once ($gab_includes . 'theme-plugins.php');

# Theme Control Panel
require_once ($gab_includes . 'theme-control-panel.php');

# Load customized comments template
require_once ($gab_includes . 'theme-comments.php');

# Load theme thumbnails
require_once ($gab_includes . 'theme-thumbnails.php');

# Load theme variables
require_once ($gab_includes . 'theme-variables.php');

function mam_post_link_nofollow ($link) {
     global $mam_set_nofollow;
     if ($mam_set_nofollow) $link = str_replace('dofollow','nofollow',$link);
     return $link;
   }
add_filter('previous_post_link','mam_post_link_nofollow');
add_filter('next_post_link','mam_post_link_nofollow');    

function contributors() {
global $wpdb;

	$authors = $wpdb->get_results("SELECT * from $wpdb->usermeta WHERE meta_key = 'wp_capabilities' AND meta_value = 'a:1:{s:6:\"author\";b:1;}'");

	foreach ( (array) $authors as $author ) {

		$author = get_userdata( $author->user_id );

		$userlevel = $author->wp2_user_level;
echo "<li>";
echo "<a href=\"".get_bloginfo('url')."/?author=";
echo $author->ID;
echo "\">";
echo get_avatar($author->ID);
echo "</a>";
echo '<div>';
echo "<a href=\"".get_bloginfo('url')."/?author=";
echo $author->ID;
echo "\">";
the_author_meta('display_name', $author->ID);
echo "</a>";
echo "</div>";
echo "</li>";
}
}

    and here the relevant code i have in single.php:

    <?php get_header(); ?>
	<?php include (TEMPLATEPATH . '/innerNarrowSidebar.php'); ?>
	<div id="innerLeft">

<?php $mam_set_nofollow = true; ?>
<div class="singlepostnavwrap">
<div class="singlepostnav">
<?php previous_post_link('%link', '&laquo; PREV ARTICLE ', TRUE); ?>
</div>

<div class="singlepostnav2">
<?php next_post_link('%link', 'NEXT ARTICLE &raquo;', TRUE); ?>
</div>
</div><!--//SINGLEPOSTNAVWRAP-->
<?php $mam_set_nofollow = true; ?>
<div id="clear"></div>

		<div class="post">
.
.
.

    i believe i have followed your directions correctly?
    but it is not working.
    when i view source this is what i see:

    <div class="singlepostnavwrap">
<div class="singlepostnav">
<a href="https://dev.bloginity.com/blog/2010/05/31/thumbnail-test/" rel="prev">&laquo; PREV ARTICLE </a></div>

<div class="singlepostnav2">
<a href="https://dev.bloginity.com/blog/2010/06/25/john-legend-musical-powerhouse-and-the-roots/" rel="next">NEXT ARTICLE &raquo;</a></div>
</div><!--//SINGLEPOSTNAVWRAP-->

    perhaps it is because it is already calling ‘rel=prev’?

    ??
    thanks so very much for your help again.

    Well, you told me that the link was showing ‘rel=”dofollow”‘. I had not seen that before, but took your word. What is actually there is ‘rel=”prev”‘ and ‘rel=”next”‘, so the function must be altered to this:

    function mam_post_link_nofollow ($link) {
     global $mam_set_nofollow;
     if ($mam_set_nofollow) $link = str_replace('prev','nofollow',$link);
     if ($mam_set_nofollow) $link = str_replace('next','nofollow',$link);
     return $link;
   }
add_filter('previous_post_link','mam_post_link_nofollow');
add_filter('next_post_link','mam_post_link_nofollow');

    im so sorry vtx, you’re right.
    i misinformed you. it wasn’t dofollow, it was prev/next.

    and it works now!!
    thank you so very much! ??
    cheers my friend-

    You are welcome!

    After thinking about this for a while, I realized that this could potentially cause problems if the strings ‘prev’ or ‘next’ occur more than once in the link. You should use this instead:

    function mam_post_link_nofollow ($link) {
     global $mam_set_nofollow;
     if ($mam_set_nofollow) $link = preg_replace('/rel="prev"/','rel="nofollow"',$link);
     if ($mam_set_nofollow) $link = preg_replace('/rel="next"/','rel="nofollow"',$link);
     return $link;
   }
add_filter('previous_post_link','mam_post_link_nofollow');
add_filter('next_post_link','mam_post_link_nofollow');

    Could a similar filter function be used to add an anchor to the end of the navigation links?

    Probably, but please explain with a couple of examples.

    Also, just a tip. Normally replies to an old post will just be ignored. You should start a new thread. I just accidently saw your reply while looking for something else.

    I actually did start a thread about this, but had no responses. Thanks for answering anyways! ??

    Okay, here’s the details. I’ve used the below code to create navigation between posts, but I need to append the #LLScontent anchor to the link so that it skips past the header.

    <div id="nav-above" class="navigation">
<div class="nav-previous"><?php previous_post_link('&laquo; %link', '%title', TRUE); ?></div>
<div class="nav-next"><?php next_post_link('%link &raquo;', '%title', TRUE); ?></div>
</div><!-- end #nav-above -->

    Again, thank you!

    Please post a link to that thread, and we will continue there.

    Sure thing: Add an anchor to a generated link

    Thanks.
