How would I count (and display) the number of times a comment meta field's value is a post's entire comments?

e.g. meta key is "fish" and key value "shark" appears in 5 comments of a post.

You should be able to do a meta_query in a WP_Comment_Query():

$args = array(
    'post_id'    => 'post-id-here',
    'meta_query' => array(
        array(
            'key'     => 'fish',
            'value'   => 'shark',
            'compare' => 'LIKE'
        )
    )
 );

// Query the comments
$comment_query = new WP_Comment_Query( $args );

// Count the number of comments
$count = count ( $comment_query );

The WP_Comment_query() accepts a 'post_id' so you can search withing a specific post's comments.

  • What would the argument be for post_idto query the current post comments? – Pete Feb 21 '18 at 9:28
  • This is what i have... $args = array( 'post_id' => $post->ID, 'meta_query' => array( array( 'key' => 'joinus', 'value' => 'Yes', 'compare' => 'LIKE' ) ) ); // Query the comments $comment_query = new WP_Comment_Query( $args ); // Count the number of comments $count = count ( $comment_query ); // echo the number of comments echo $count; – Pete Feb 21 '18 at 9:32
  • @Pete Are you sure that the $post->ID is set? Where and how are you using this code? – Jack Johansson Feb 21 '18 at 9:51
  • I'm using this in my single.php loop - so I guess I need to find the current post ID – Pete Feb 21 '18 at 10:10
