In WordPress, how do I display a single random post of a custom post type in a sidebar widget?

I have created a custom post type – Testimonials – for a WP site I am working on. I want to display a single random testimonial in my sidebar – without using a plugin if possible. Do I need to create a text widget with the proper post query? If so, what would it look like?

Many thanks,

  1. If you want you can directly paste following code snippet in your sidebar.php where you want to show the Testimonials (make sure whether it’s testimonials/Testimonials)

    <?php
      $args = array(
        'post_type'=>'testimonials', 
        'orderby'=>'rand', 
        'posts_per_page'=>'1'
      );
    
      $testimonials=new WP_Query($args);
    
      while ($testimonials->have_posts()) : $testimonials->the_post(); 
    ?>
        <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
        <p><?php the_excerpt(); // or the_content(); ?></p>
    <?php 
      endwhile;
      wp_reset_postdata();
    ?>
