I am trying to add a button to take the viewer to a random post. Below's the code I am using:-

    <?php query_posts(array('orderby' => 'rand', 'posts_per_page' => 1));
    if (have_posts()) :
    while (have_posts()) : the_post(); ?>
        <div class="post-lot">
        <a href="<?php the_permalink() ?>">Yes, Robo! Take me there.</a>
    <?php endwhile;
    endif; ?>    

But, it keeps showing two links. If I change posts_per_page to 2, it shows 3 links. I tried adding wp_reset_query but the issue still persists.

  • Where is this code running? The context may provide more clues, especially if you can paste the code wrapped around it. :) – WebElaine May 9 '18 at 16:06

    Never use query_posts() until you are 100% sure you have to do so. Use get_posts() or WP_Query instead. See the Code Reference. – Max Yudin May 9 '18 at 16:12
  • @WebElaine Its running on the 404 page. – user1928108 May 9 '18 at 16:17
  • @MaxYudin I also tried using WP_Query as seen here - wpexplorer.com/random-posts-wordpress but the result's the same – user1928108 May 9 '18 at 16:22

Most probably you have a sticky post there. If you want exact number of posts you need to ignore sticky posts. So your query should look like this:

query_posts( array(
    'orderby' => 'rand',
    'posts_per_page' => 1,
    'ignore_sticky_posts' => 1,
) );

or as suggested, never use query_posts()

$query = new WP_Query( array(
    'orderby' => 'rand',
    'posts_per_page' => 1,
    'ignore_sticky_posts' => 1,
) );
  • Wow, thanks a lot for that, this fixed the issue and as suggested, I will implement WP_Query. – user1928108 May 9 '18 at 16:59
