For some reason a title
attribute is not appended to next_post_link
and prev_post_link
calls in WordPress. How can I add one?

As I deleted the Repo on GitHub, here's a new answer.
add_filter( 'previous_post_link', 'wpse13044_adjacent_post_link_tooltip', 10, 2 );
add_filter( 'next_post_link', 'wpse13044_adjacent_post_link_tooltip', 10, 2 );
function wpse13044_adjacent_post_link_tooltip( $format, $link )
{
$previous = 'previous_post_link' === current_filter();
// Get the next/previous post object
$post = get_adjacent_post(
false
,''
,$previous
);
// Copypasta from cores `get_adjacent_post_link()` fn
'' === $title = get_the_title( $post->ID );
AND $title = $previous
? sprint( __( 'Previous Post: %s', 'your_textdomain' ), $title )
: sprint( __( 'Next Post: %s', 'your_textdomain' ), $title );
$format = str_replace(
'rel="'
,sprintf(
'title="%s" rel="'
,$title
)
,$format
);
return "<span class='some classes'>{$format}</span>";
}

@Infocentre: It's not meant to be a plugin. I wrote it for all the answers about pagination. It's over documented and shows you everything you might want to know about pagination and all possibilities. So take a look (especially at the line number i told you) and see how to do it.– kaiserMar 25, 2011 at 12:53

Look into the plugin starting at line 155 with
<li class="page-num page-num-prev">
and how i rebuild theprev_post_link()
function. This shows you a possiblity how you can modify and build the links the way you want to have it. (Mostly copy&paste).– kaiserMar 25, 2011 at 14:32 -

No need for functions and filters all you need to do is to use get_adjacent_post
instead of next_post_link
and prev_post_link
, Note that get_adjacent_post
is used to get previous and next post, you can read about it here
To get previous post and it's title attribute use this
$prev_post = get_adjacent_post(false, '', true);
if(!empty($prev_post)) {
echo '<a href="' . get_permalink($prev_post->ID) . '" title="' . $prev_post->post_title . '">' . $prev_post->post_title . '</a>'; }
To get next post and it's title attribute use this
$next_post = get_adjacent_post(false, '', false);
if(!empty($next_post)) {
echo '<a href="' . get_permalink($next_post->ID) . '" title="' . $next_post->post_title . '">' . $next_post->post_title . '</a>'; }

1Thank you! Cleanest solution. Weird no body bothers to test this, it works great and it also works in woocommerce -- obviously since products are posts. Dec 10, 2015 at 17:39

I'm trying to do this right now as well. The filter function seems like the best bet.
This is where I'm at now, but I can't seem to get the title of the next or previous post and pass it to the filter.
Edit: Figured it out. A bit hackey probably, but it works.
add_filter('next_post_link','add_title_to_next_post_link');
function add_title_to_next_post_link($link) {
global $post;
$post = get_post($post_id);
$next_post = get_next_post();
$title = $next_post->post_title;
$link = str_replace("rel=", " title='".$title."' rel", $link);
return $link;
}
add_filter('previous_post_link','add_title_to_previous_post_link');
function add_title_to_previous_post_link($link) {
global $post;
$post = get_post($post_id);
$previous_post = get_previous_post();
$title = $previous_post->post_title;
$link = str_replace("rel=", " title='".$title."' rel", $link);
return $link;
}
A bit old perhaps, and I wasn't really sure on how to make a comment on a reply...
In short, after looking for the same solution I've modified Picard102's suggestion just a tiny bit:
/**
* Filter previous_post_link and next_post_link
*/
function filter_next_post_link($link) {
global $post;
$post = get_post($post_id);
$next_post = get_next_post();
$title = $next_post->post_title;
$link = str_replace("rel=", 'title="' . $title . '" rel=', $link);
return $link;
}
add_filter('next_post_link', 'filter_next_post_link');
function filter_previous_post_link($link) {
global $post;
$post = get_post($post_id);
$previous_post = get_previous_post();
$title = $previous_post->post_title;
$link = str_replace("rel=", 'title="' . $title . '" rel=', $link);
return $link;
}
add_filter('previous_post_link', 'filter_previous_post_link');
Shortened the code a little.
/*
* Add "title=" to previous_post_link and next_post_link
*/
add_filter('next_post_link', function($link) {
$next_post = get_next_post();
$title = $next_post->post_title;
$link = str_replace('href=', 'title="'.$title.'" href=', $link);
return $link;
});
add_filter('previous_post_link', function($link) {
$previous_post = get_previous_post();
$title = $previous_post->post_title;
$link = str_replace('href=', 'title="'.$title.'" href=', $link);
return $link;
});
next|previous_post_link
filter. One way is to use regex. btw, paste your current prev/next code.
