Code generation for the inventory adjustment recording function in the PHP inventory management system

With the development of e-commerce, inventory management has become important in the daily operations of enterprises. link. To facilitate inventory management, many businesses choose to use computer software to record and track inventory. This article will introduce how to use PHP to write the inventory adjustment recording function in an inventory management system and provide corresponding code examples.

First, we need to create a class called InventoryAdjustment to handle inventory adjustment records. This class should contain the following attributes: adjustment record ID, product ID, adjustment quantity, adjustment type, adjustment date, etc. Depending on the requirements, we may also need other attributes, such as the reason for adjustment, etc. The following is a simple sample code:

class InventoryAdjustment
{
    private $id;
    private $product_id;
    private $quantity;
    private $adjustment_type;
    private $adjustment_date;

    // 构造函数
    public function __construct($id, $product_id, $quantity, $adjustment_type, $adjustment_date)
    {
        $this->id = $id;
        $this->product_id = $product_id;
        $this->quantity = $quantity;
        $this->adjustment_type = $adjustment_type;
        $this->adjustment_date = $adjustment_date;
    }

    // 获取调整记录ID
    public function getId()
    {
        return $this->id;
    }

    // 获取商品ID
    public function getProductId()
    {
        return $this->product_id;
    }

    // 获取调整数量
    public function getQuantity()
    {
        return $this->quantity;
    }

    // 获取调整类型
    public function getAdjustmentType()
    {
        return $this->adjustment_type;
    }

    // 获取调整日期
    public function getAdjustmentDate()
    {
        return $this->adjustment_date;
    }
}

Next, we can create a class called InventoryAdjustmentManager to manage inventory adjustment records. This class should contain the following methods: add inventory adjustment records, obtain a list of inventory adjustment records, obtain inventory adjustment records based on ID, etc. The following is a sample code:

class InventoryAdjustmentManager
{
    private $adjustments;

    // 构造函数
    public function __construct()
    {
        $this->adjustments = [];
    }

    // 添加库存调整记录
    public function addAdjustment(InventoryAdjustment $adjustment)
    {
        $this->adjustments[] = $adjustment;
    }

    // 获取库存调整记录列表
    public function getAdjustmentList()
    {
        return $this->adjustments;
    }

    // 根据ID获取库存调整记录
    public function getAdjustmentById($id)
    {
        foreach ($this->adjustments as $adjustment) {
            if ($adjustment->getId() == $id) {
                return $adjustment;
            }
        }
        return null;
    }
}

Now, we can use these classes to implement the functionality of inventory adjustment records.

// 创建库存调整管理器
$adjustmentManager = new InventoryAdjustmentManager();

// 创建调整记录
$adjustment1 = new InventoryAdjustment(1, 1, 10, '入库', '2021-01-01');
$adjustment2 = new InventoryAdjustment(2, 2, -5, '出库', '2021-01-02');

// 添加调整记录到管理器
$adjustmentManager->addAdjustment($adjustment1);
$adjustmentManager->addAdjustment($adjustment2);

// 获取所有调整记录
$adjustmentList = $adjustmentManager->getAdjustmentList();
foreach ($adjustmentList as $adjustment) {
    echo '调整记录ID：' . $adjustment->getId() . '<br>';
    echo '商品ID：' . $adjustment->getProductId() . '<br>';
    echo '调整数量：' . $adjustment->getQuantity() . '<br>';
    echo '调整类型：' . $adjustment->getAdjustmentType() . '<br>';
    echo '调整日期：' . $adjustment->getAdjustmentDate() . '<br>';
    echo '<hr>';
}

// 根据ID获取调整记录
$adjustmentId = 1;
$adjustment = $adjustmentManager->getAdjustmentById($adjustmentId);
if ($adjustment) {
    echo '调整记录ID：' . $adjustment->getId() . '<br>';
    echo '商品ID：' . $adjustment->getProductId() . '<br>';
    echo '调整数量：' . $adjustment->getQuantity() . '<br>';
    echo '调整类型：' . $adjustment->getAdjustmentType() . '<br>';
    echo '调整日期：' . $adjustment->getAdjustmentDate() . '<br>';
} else {
    echo '未找到ID为' . $adjustmentId . '的调整记录';
}

The above is a code example of using PHP to write the inventory adjustment recording function in the inventory management system. Through these classes and methods, we can easily implement functions such as adding and obtaining inventory adjustment records, and conveniently manage and query inventory adjustment records. Of course, we can expand and optimize the code according to actual needs.
