Woocommerce menggemakan total penjualan ritel per produk

Widget dasbor WooCommerce 2.2 menggunakan kode berikut untuk menghitung penjualan ritel selama sebulan terakhir:

    // 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 ) ) );

lalu nanti di tampilkan dengan :

wc_price( $sales );

Karena tanggal dibatasi di 2 baris terakhir $query['where'] string, saya kira itu bisa dihapus jika Anda ingin mendapatkan total penjualan sepanjang masa.

    // 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 ) );

Ini menurut saya sebagai permintaan yang cukup intensif, jadi jika itu akan dijalankan sepanjang waktu, Anda mungkin ingin menyelidiki Transien.

Saya kurang yakin tentang memodifikasinya untuk masing-masing produk karena saya lemah dalam SQL, tetapi inilah upaya untuk mendapatkan string "where" untuk menentukan ID produk.

    // 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 ) );
