Select only post id and meta value with WP_Query
I’m developing a simple rank plugin, which allows visitors to like the posts and also shows the total like scores for each tag in the plugin’s admin page. I need both post IDs (in order to reach the tag data of them) and like values.
This is my query at the moment:
$args = array( 'meta_key' => '_Like', 'orderby' => 'meta_value', ); $query = new WP_Query($args);
But this query returns the complete post object, it’s not efficient for the memory. I only need
_Like value and the
post_id. Is there a better query for this ?
