對PHP寫入庫存管理系統中的庫存盤點功能進行程式碼生成

CREATE TABLE `inventory_check` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `check_date` date NOT NULL,
  `check_by` int(11) NOT NULL,
  PRIMARY KEY (`id`)
);

CREATE TABLE `inventory` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `product_id` int(11) NOT NULL,
  `quantity` int(11) NOT NULL,
  PRIMARY KEY (`id`)
);

// 获取盘点单的ID
$check_id = $_POST['check_id'];

// 获取产品ID和实际库存数量
$product_id = $_POST['product_id'];
$actual_quantity = $_POST['actual_quantity'];

// 更新库存记录
$sql = "UPDATE inventory SET quantity = :actual_quantity WHERE id = :product_id";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':actual_quantity', $actual_quantity, PDO::PARAM_INT);
$stmt->bindParam(':product_id', $product_id, PDO::PARAM_INT);
$stmt->execute();

// 获取盘点单的ID和盘点人员的信息
$check_id = $_POST['check_id'];
$check_by = $_POST['check_by'];

// 更新盘点单的状态和盘点人员信息
$sql = "UPDATE inventory_check SET status = 'completed', check_by = :check_by WHERE id = :check_id";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':check_by', $check_by, PDO::PARAM_INT);
$stmt->bindParam(':check_id', $check_id, PDO::PARAM_INT);
$stmt->execute();
