Most commented posts by time period (last 12h, last 24h and etc)

I have this code which works great.

 <?php 
      $result = $wpdb->get_results("SELECT comment_count, ID, post_title FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 25"); // NUMBER OF POSTS
         foreach ($result as $topten) {
             $postid = $topten->ID;
             $title = $topten->post_title;
             $commentcount = $topten->comment_count;
             if ($commentcount != 0) {
      ?>
        <a href="<?php echo get_permalink($postid); ?>"><span class="tags"> <?php echo $title ?></span></a>
   
   <?php } } ?>

Now it displays (order) the most popular posts by comment count (ALL-TIME).

I know that WordPress understands command ‘period’:

   period=1hourago

Basically, I’m trying to get the above code working with the period, so that I could define:

24hoursago

12hoursago

and so on…

I know I need to somehow integrate this into code:

 'date_query' => [
        [
           
        ]
    ],

But I can’t seem to find a way of putting all together.

I saw the idea from: https://www.bitochat.com

Need help.

Method 1

So if you want to get the posts that were commented within the last xx hours, e.g. 12 hours, then try one of the following:

Note though, I’m selecting only published posts (post_status = 'publish') and of the post type (post_type = 'post').

And just replace the value of $hours with your preferred number of hours.

Using TIMESTAMPDIFF().

$hours = 12;

$result = $wpdb->get_results( $wpdb->prepare( "
    SELECT p.comment_count, p.ID, p.post_title
        FROM $wpdb->posts p
        INNER JOIN $wpdb->comments c ON c.comment_post_ID = p.ID
    WHERE p.post_type = 'post'
        AND p.post_status = 'publish'
        AND ( TIMESTAMPDIFF( HOUR, c.comment_date, NOW() ) <= %d )
    GROUP BY p.ID
    ORDER BY p.comment_count DESC
    LIMIT 0, 25
", $hours ) );

Or calculate the date and time of xx hours ago and use comment_date >= <date-time xx hours ago>.

$hours = 12;

$timestamp = current_time( 'timestamp' );
$date_ago = date( 'Y-m-d H:i:s', $timestamp - $hours * HOUR_IN_SECONDS );

$result = $wpdb->get_results( $wpdb->prepare( "
    SELECT p.comment_count, p.ID, p.post_title
        FROM $wpdb->posts p
        INNER JOIN $wpdb->comments c ON c.comment_post_ID = p.ID
    WHERE p.post_type = 'post'
        AND p.post_status = 'publish'
        AND c.comment_date >= %s
    GROUP BY p.ID
    ORDER BY p.comment_count DESC
    LIMIT 0, 25
", $date_ago ) );
