Generally, the WordPress recent posts are displayed in the descending order of the date of publishing. This recent list of posts can be of any category under which it is posted. If you want to list the recent posts by a specified category, then this WordPress post will be helpful for you to implement it in your WordPress site.
WordPress category page lists recent posts by category. In a previous tutorial, we have seen how to add category menu by using walker class to navigate to the WordPress category page. If you want to display recent posts by category on the homepage or in the sidebar tile, it is easy to implement by changing the theme files or by creating custom widgets.
In this section, I have shown the code to be used for displaying recent posts by category. In this code, I request WP_Query() to fetch posts by category. I am sending the category id and the limit as the parameters to execute the WordPress query. This function will return the posts data as required. By iterating the posts array data, the recent post list can be displayed. Add this code wherever you want to display the recent post list.
<?php $post_by_category = new WP_Query( 'cat=19&posts_per_page=15' ); if ($post_by_category->have_posts()) : ?> <h2 class="heading">Recent Posts</h2> <?php while ($post_by_category->have_posts()) : $post_by_category->the_post(); ?> <div class="entry"> <div class="post-image"> <?php echo_first_image ( get_the_ID (), true );?> </div> <div class="post-data"> <h2> <a href="<?php the_permalink() ?>"> <?php the_title(); ?> </a> </h2> <div class="desc"> <?php the_excerpt_rss(); ?> </div> </div> </div> <?php endwhile; endif; ?>
There are WordPress plugins for displaying recent posts by specifying one or more categories. The plugin configuration page will have controls to customize settings to display recent post.
