I am trying to cache the returned data from a query using WP_Query.

It doesn't seem to be storing any where near the time I have specified. Sometimes its refreshing on every page load.

What might I be doing wrong?

<?php 
    // get our transient data if it exists
    // prevents pummelling the database with multiple random queries
    $tipsloop = get_transient ('homepage_tipsloop');
    if (!$tipsloop )
      {
       echo 'THIS IS NEW TRANSIENT DATA';
       $tipsloop = new WP_Query( array( 'cat' => '8', 'posts_per_page' => '1' , 'orderby' => 'rand') ); 
       set_transient ('homepage_tipsloop' , $tipsloop , MINUTE_IN_SECONDS * 5 ); // cached for 5 minutes
      }
?>

<!-- // Tips Loop -->
<?php while ($tipsloop->have_posts()) : $tipsloop->the_post(); 
    echo get_the_post_thumbnail($page->ID, 'homefooter-thumb'); ?>
      <div class="home-hotspots-tipscopy">
        <?php the_content(); ?>
      </div>
<p>
      <a href="/category/tips/">MORE TIPS</a>
    </p>
<?php endwhile;  ?>

I've change my comment into an answer. Please accept as solution. Change set_transient ('homepage_tipsloop' , $tipsloop , MINUTE_IN_SECONDS * 5 ); to set_transient ('homepage_tipsloop' , $tipsloop , 5 * MINUTE_IN_SECONDS ); as stated in the codex

  • Thanks i've switched it over. Seems to be working, not sure if its actually setting for 5 mins or not. Will have to do some testing – EHerman Mar 12 '14 at 19:01

    have you actually tried this out? the order doesn't matter, 60 * 5 and 5 * 60 are obviously the same result. – Milo Mar 12 '14 at 19:11
  • Yea, obviously would result the same. Seems to be caching appropriately now. I am on a WP Engine account. I went in and purged the cache, and made sure things were caching for around 5 minutes. Your correct, the order does not matter – EHerman Mar 14 '14 at 13:23
