WooCommerce 2.2 dashboard-widgetten bruger følgende kode til at beregne detailsalget over den seneste måned:
// Sales
$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' ";
$query['where'] .= "AND posts.post_date >= '" . date( 'Y-m-01', current_time( 'timestamp' ) ) . "' ";
$query['where'] .= "AND posts.post_date <= '" . date( 'Y-m-d H:i:s', current_time( 'timestamp' ) ) . "' ";
$sales = $wpdb->get_var( implode( ' ', apply_filters( 'woocommerce_dashboard_status_widget_sales_query', $query ) ) );
og senere vise det med :
wc_price( $sales );
Fordi datoerne bliver begrænset i de sidste 2 linjer i $query['where']
streng, jeg formoder, at de kunne slettes, hvis du ønskede at få det samlede salg gennem tiden.
// 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 ) );
Dette forekommer mig at være en ret intensiv forespørgsel, så hvis den skal køres hele tiden, vil du måske undersøge Transients.
Jeg er mindre sikker på at ændre det for det enkelte produkt, fordi jeg er svag i SQL, men her er et forsøg på at få "hvor"-strengen til at angive et produkts ID.
// All-time Sales for specific product, maybe
$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 ) );
