SUM items from Array?

  • I’m trying to add up all the comment meta for a particular meta key for a particular post. I feel like I’m close, but for some reason my output is always either ‘ArrayArrayArrayArrayArray’ or 1010101010, but I can never seem to get all those 10’s to add up. Here is what I have currently:

    <?php
$postid = get_the_ID(); // get id of current post
$args = array(
	'post_id'      => $postid,
	'count'        => false,
	'meta_key'     => 'price',
	'meta_value'   => '',
	'meta_query'   => ''
);

// The Query
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );

// Comment Loop
if ( $comments ) {
	foreach ($comments as $comment) {
	$rating = array($comment->meta_value);
	echo array_sum($rating);}
} else {
	 echo 'no price rating to calculate';
	}
?>

    >How do I get the $rating to be the added total of all the $comment->meta_value

    Try it with this:

    // Comment Loop
if ( $comments ) {
	$rating = 0;
	foreach ( $comments as $comment ) {
		$rating += absint( $comment->meta_value ); // make sure it's an integer
	}
	echo ( $rating > 0 ) ? $rating : 'no ratings yet';
} else {
	echo 'no price rating to calculate';
}

    Or with this:

    // Comment Loop
if ( $comments ) {
	$meta_value = wp_list_pluck( $comments, 'meta_value' ); // get all meta_values
	$meta_value = array_map( 'intval', (array) $meta_value ); // make sure they are all integers
	$meta_value = array_sum( $rating );
	echo ( $rating > 0 ) ? $rating : 'no ratings yet';
} else {
	echo 'no price rating to calculate';
}

    Thanks, I actually just got it solved before I saw this – but ended up doing something a little different. This looks much cleaner than my code though haha

    No problem. I’m glad you found your own solution ??
