Next and/or previous post content

Question

How can I show the content in next or previous post?

For example, I use this to display the next post link with title:

   <div class="alignleftfp">
    <?php next_post_link('%link', '%title'); ?>
    </div>
    <div class="alignrightfp">
    <?php previous_post_link('%link', '%title'); ?>
    </div>

Is it possible to show the content of that post (100 Words)?

Answer 1

Take a look at the get_adjacent_post function.

It takes three paramters, all of which are optional:

• a boolean, whether the post should be from the same category
• a string of category IDs that should be excluded
• a boolean, whether the previous (true) or next (false) post should be retrieved.

Hence the previous post, regardless of category can be retrieved via

$prev_post = get_adjacent_post( false, '', true );

and the next via

$next_post = get_adjacent_post( false, '', false );

If successful, the function will return a complete post object, hence:

echo $prev_post->post_excerpt;

should do.
