get_post_meta to check for 0 meta value

  • Hi,

    I’d like to check for 0 meta value in post_meta table. I’m trying something like this but no luck so far:

    $meta_values = get_post_meta($post->ID, $meta_key, $single = true);
                foreach($meta_values as $value){
                    if( $value==0){
                        $num_ratings++;
                    }
                    }

    Reason for this is that I only need to count number of non 0 meta_value records per post ID per given meta_key.

  • setting $single to true returns the value as a string, not an array

    $meta_values = get_post_meta($post->ID, 'keyname', false);

    will return as array.

    You should also check meta_values after the fact with is_array()

    if (is_array($meta_values)) {
