 <?php

$related = get_posts( array( 'category__in' => wp_get_post_categories($post->ID), 'numberposts' => 5, 'post__not_in' => array($post->ID) ) );
if( $related ) foreach( $related as $post ) {
setup_postdata($post); ?>
 <ul> 
        <li>
        <a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
            <?php the_content('Read the rest of this entry &raquo;'); ?>

The question has already been asked and the answer has been posted too,

How to display related posts from same category?

Add this code inside your single.php after a loop wherever you want to show related post,

<?php

$related = get_posts( array( 'category__in' => wp_get_post_categories($post->ID), 'numberposts' => 5, 'post__not_in' => array($post->ID) ) );
if( $related ) foreach( $related as $post ) {
setup_postdata($post); ?>
 <ul> 
        <li>
        <a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a>
            <?php the_content('Read the rest of this entry &raquo;'); ?>
        </li>
    </ul>   
<?php }
wp_reset_postdata(); ?>

It will display related post from the same category with the post excerpt and title , however if want this code to display just the title of related post then remove this line,

<?php the_content('Read the rest of this entry &raquo;'); ?>

Hiernocheine saubere und sehrflexible Option:

Fügen Sie diesen Codein Ihre Dateifunctions.phpein.

 function example_cats_related_post() {

    $post_id = get_the_ID();
    $cat_ids = array();
    $categories = get_the_category( $post_id );

    if(!empty($categories) && is_wp_error($categories)):
        foreach ($categories as $category):
            array_push($cat_ids, $category->term_id);
        endforeach;
    endif;

    $current_post_type = get_post_type($post_id);
    $query_args = array( 

        'category__in'   => $cat_ids,
        'post_type'      => $current_post_type,
        'post_not_in'    => array($post_id),
        'posts_per_page'  => '3'


     );

    $related_cats_post = new WP_Query( $query_args );

    if($related_cats_post->have_posts()):
         while($related_cats_post->have_posts()): $related_cats_post->the_post(); ?>
            <ul>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                    <?php the_content(); ?>
                </li>
            </ul>
        <?php endwhile;

        // Restore original Post Data
        wp_reset_postdata();
     endif;

}
 

Jetzt können Sie die Funktioneinfach überall auf Ihrer Site aufrufen,indem Sie Folgendes verwenden:

 <?php example_cats_related_post() ?>
 

Möglicherweisemöchten Sie die Listenelementeentfernen odernach Bedarfformatieren.

Here another clean and very flexible option:

Put this code in your functions.php file

function example_cats_related_post() {

    $post_id = get_the_ID();
    $cat_ids = array();
    $categories = get_the_category( $post_id );

    if(!empty($categories) && is_wp_error($categories)):
        foreach ($categories as $category):
            array_push($cat_ids, $category->term_id);
        endforeach;
    endif;

    $current_post_type = get_post_type($post_id);
    $query_args = array( 

        'category__in'   => $cat_ids,
        'post_type'      => $current_post_type,
        'post_not_in'    => array($post_id),
        'posts_per_page'  => '3'


     );

    $related_cats_post = new WP_Query( $query_args );

    if($related_cats_post->have_posts()):
         while($related_cats_post->have_posts()): $related_cats_post->the_post(); ?>
            <ul>
                <li>
                    <a href="<?php the_permalink(); ?>">
                        <?php the_title(); ?>
                    </a>
                    <?php the_content(); ?>
                </li>
            </ul>
        <?php endwhile;

        // Restore original Post Data
        wp_reset_postdata();
     endif;

}

Now you can simply call the function anywhere in your site using:

<?php example_cats_related_post() ?>

You may want to remove the list elements or style them as per your need.
