Code generation for the inventory transfer review function in the PHP inventory management system

Inventory transfer is a common operation within the enterprise, which involves two links: transfer out of the warehouse and transfer into the warehouse. In an inventory management system, in order to ensure the accuracy and transparency of inventory transfer, it is usually necessary to introduce the inventory transfer audit function. This article will introduce how to use PHP to write the code for the inventory transfer review function.

The inventory transfer review function mainly involves three steps: creating a transfer order, reviewing the transfer order, and performing a transfer operation. Below are code examples for these three steps.

1. Create a transfer order

In the inventory management system, users can create a new transfer order. Transfer orders usually include transfer order number, transfer time, transfer type, transfer quantity and other information. The following is a simplified code example:

<?php

function createTransferOrder($orderNumber, $transferDate, $transferType, $transferQuantity) {
    // 将调拨单数据插入到数据库中
    $sql = "INSERT INTO transfer_orders (order_number, transfer_date, transfer_type, transfer_quantity, status) VALUES ('$orderNumber', '$transferDate', '$transferType', '$transferQuantity', 'pending')";
    $result = mysqli_query($connection, $sql);
    
    if ($result) {
        echo "调拨单创建成功！";
    } else {
        echo "创建调拨单时发生错误：" . mysqli_error($connection);
    }
}

?>

2. Audit transfer order

In the inventory transfer review function, the system administrator can review the transfer order. During review, the administrator can choose to approve or reject the transfer order. The following is a simplified code example:

<?php

function approveTransferOrder($orderId) {
    // 更新调拨单的状态为approved
    $sql = "UPDATE transfer_orders SET status='approved' WHERE id='$orderId'";
    $result = mysqli_query($connection, $sql);
    
    if ($result) {
        echo "调拨单审核通过！";
    } else {
        echo "审核调拨单时发生错误：" . mysqli_error($connection);
    }
}

function rejectTransferOrder($orderId) {
    // 更新调拨单的状态为rejected
    $sql = "UPDATE transfer_orders SET status='rejected' WHERE id='$orderId'";
    $result = mysqli_query($connection, $sql);
    
    if ($result) {
        echo "调拨单审核拒绝！";
    } else {
        echo "审核调拨单时发生错误：" . mysqli_error($connection);
    }
}

?>

3. Perform the transfer operation

After the transfer order is approved, the user can perform the transfer operation and transfer the inventory from the warehouse Move to the transfer inbound warehouse. The following is a simplified code example:

<?php

function executeTransfer($orderId) {
    // 根据调拨单查询调拨信息
    $sql = "SELECT transfer_quantity, transfer_type FROM transfer_orders WHERE id='$orderId'";
    $result = mysqli_query($connection, $sql);
    $row = mysqli_fetch_assoc($result);
    $transferQuantity = $row['transfer_quantity'];
    $transferType = $row['transfer_type'];
    
    // 更新出库仓库和入库仓库的库存数量
    $sql = "UPDATE warehouses SET quantity = quantity - $transferQuantity WHERE type='$transferType' AND location='$warehouseOut'";
    $result1 = mysqli_query($connection, $sql);
    
    if ($result1) {
        $sql = "UPDATE warehouses SET quantity = quantity + $transferQuantity WHERE type='$transferType' AND location='$warehouseIn'";
        $result2 = mysqli_query($connection, $sql);
        
        if ($result2) {
            echo "调拨操作执行成功！";
        } else {
            echo "执行调拨操作时发生错误：" . mysqli_error($connection);
        }
    } else {
        echo "执行调拨操作时发生错误：" . mysqli_error($connection);
    }
}

?>

The above is a code example for the inventory transfer review function. Through these codes, the creation, review and execution of inventory transfers can be achieved, improving the accuracy and efficiency of the inventory management system. Of course, depending on actual needs, you may also need to add other functions, such as permission management, transfer record viewing, etc. I hope this article can help you write PHP code for inventory transfer review function.
