I already asked this question here and got a partially working answer. But to recap from my previous question. I am querying for woocommerce products in a post query and then displaying them in a list for a leaderboard. I also need to display the individual retail amount sold for each product. When I say retail amount, I don't mean the quantity sold, I mean the total dollar amount sold. I now have working code to get the total retail sold for the whole store, which is pretty awesome.
// All-time Sales for entire store
$query = array();
$query['fields'] = "SELECT SUM( postmeta.meta_value ) FROM {$wpdb->posts} as posts";
$query['join'] = "INNER JOIN {$wpdb->postmeta} AS postmeta ON posts.ID = postmeta.post_id ";
$query['where'] = "WHERE posts.post_type IN ( '" . implode( "','", wc_get_order_types( 'reports' ) ) . "' ) ";
$query['where'] .= "AND posts.post_status IN ( 'wc-" . implode( "','wc-", apply_filters( 'woocommerce_reports_order_statuses', array( 'completed', 'processing', 'on-hold' ) ) ) . "' ) ";
$query['where'] .= "AND postmeta.meta_key = '_order_total' ";
$sales = $wpdb->get_var( implode( ' ', $query ) );
Now the issue is, I cant seem to get this to work for an individual product. At the moment I have this code:
$product_id = 10;
$query = array();
$query['fields'] = "SELECT SUM( postmeta.meta_value ) FROM {$wpdb->posts} as posts";
$query['join'] = "INNER JOIN {$wpdb->postmeta} AS postmeta ON posts.ID = postmeta.post_id ";
$query['where'] = sprintf( "WHERE posts.ID = %n", $product_id );
$query['where'] .= "AND posts.post_status IN ( 'wc-" . implode( "','wc-", apply_filters( 'woocommerce_reports_order_statuses', array( 'completed', 'processing', 'on-hold' ) ) ) . "' ) ";
$query['where'] .= "AND postmeta.meta_key = '_order_total' ";
$sales = $wpdb->get_var( implode( ' ', $query ) );
But, unfortunately, it displays only 0's. Is there anyone out there that can help A. fix the code for the individual product, or B. find a better way to do this on a product to product basis?
Thank you for any help on the subject.
