確定客戶在 WooCommerce 中的購買歷史
開發 WooCommerce 插件時,通常有必要檢查客戶之前是否進行過購買。這些資訊可用於相應地定制優惠和促銷活動。
檢查客戶購買歷史記錄
要確定客戶是否進行過任何購買,輕量級且優化的函數可以受僱:
function has_bought( $value = 0 ) { if ( ! is_user_logged_in() && $value === 0 ) { return false; } global $wpdb; // Based on user ID (registered users) if ( is_numeric( $value) ) { $meta_key = '_customer_user'; $meta_value = $value == 0 ? (int) get_current_user_id() : (int) $value; } // Based on billing email (Guest users) else { $meta_key = '_billing_email'; $meta_value = sanitize_email( $value ); } $paid_order_statuses = array_map( 'esc_sql', wc_get_is_paid_statuses() ); $count = $wpdb->get_var( $wpdb->prepare(" SELECT COUNT(p.ID) FROM {$wpdb->prefix}posts AS p INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id WHERE p.post_status IN ( 'wc-" . implode( "','wc-", $paid_order_statuses ) . "' ) AND p.post_type LIKE 'shop_order' AND pm.meta_key = '%s' AND pm.meta_value = %s LIMIT 1 ", $meta_key, $meta_value ) ); // Return a boolean value based on orders count return $count > 0; }
用法範例
1.檢查註冊用戶購買情況:
if( has_bought() ) echo '<p>You have already made a purchase</p>'; else echo '<p>Welcome, for your first purchase you will get a discount of 10%</p>';
2.根據帳單電子郵件檢查來賓用戶購買狀況:
// Define the billing email (string) $email = '[email protected]'; if( has_bought( $email ) ) echo '<p>customer have already made a purchase</p>'; else echo '<p>Customer with 0 purchases</p>'
透過使用此功能,插件開發人員可以輕鬆確定客戶在WooCommerce 中是否有購買歷史記錄,從而為增強的客戶提供有針對性的促銷和折扣訂婚。
