					Sorry, I made a mistake copying the question. Here's the correct one:

Title: Display Related Posts by Current Post Category in WordPress
function wpturbo_display_related_posts() {
    $categories = get_the_category();
    $category_ids = array();
    foreach( $categories as $category ){
        $category_ids[] = $category->term_id;
    $args = array(
        'category__in' => $category_ids,
        'post__not_in' => array( get_the_ID() ),
        'posts_per_page' => 4,
        'ignore_sticky_posts' => 1
    $related_posts = new WP_Query( $args );
    if ( $related_posts->have_posts() ) {
        echo '<ul>';
        while ( $related_posts->have_posts() ) {
            echo '<li><a href="' . get_permalink() . '">' . get_the_title() . '</a></li>';
        echo '</ul>';
add_action( 'wpturbo_display_related_posts', 'wpturbo_display_related_posts' );

The code snippet provided above allows you to display related posts based on the current post’s category in WordPress. This can be useful for increasing engagement and keeping visitors on your website by showing them content that is relevant to what they are currently viewing.

Let’s go through the code step by step to understand how it works.

First, we define a function called wpturbo_display_related_posts(), which will be responsible for retrieving and displaying the related posts.

Next, we use the get_the_category() function to get all the categories associated with the current post. This returns an array of category objects.

We then create an empty array called $category_ids to store the IDs of the categories associated with the post.

We iterate through each category using a foreach loop and collect the IDs by accessing the term_id property of each category object. We add each ID to the $category_ids array.

After gathering the category IDs, we define an array called $args which will be used as arguments for the WP_Query object. These arguments specify how the related posts should be queried.

In the $args array, we set the 'category__in' parameter to the $category_ids array, which tells WordPress to retrieve posts that belong to any of the specified categories.

We also set 'post__not_in' parameter to exclude the current post from the results. This prevents the current post from being displayed as a related post.

We set 'posts_per_page' to limit the number of related posts to be displayed. You can modify this value to show more or fewer posts.

The 'ignore_sticky_posts' parameter is set to 1, which means sticky posts will not be included in the results. Sticky posts are posts that are "stuck" to the top of the blog page regardless of the publishing date.

We then use the $args array to create a new instance of WP_Query called $related_posts.

We check if $related_posts has any posts using the have_posts() method. If there are related posts available, we start the output by echoing an opening <ul> tag.

Inside a while loop, we use the the_post() method to set up the current post within the loop. This allows us to access the post’s permalink and title using the get_permalink() and get_the_title() functions, respectively.

We then echo an <li> element with a link to the related post’s permalink and the related post’s title inside.

Finally, we echo a closing </ul> tag.

After the loop, we call wp_reset_postdata() to reset the post data back to the main query so that it doesn’t interfere with any other queries on the page.

Lastly, we use the add_action() function to hook the wpturbo_display_related_posts() function to the wpturbo_display_related_posts action. This action can be called in your theme or plugin to display the related posts.

By implementing this code snippet, you will be able to display a list of related posts based on the current post’s category. This can enhance the user experience and encourage readers to explore more content on your website.
