PHP development to build an enterprise resource planning (ERP) system with supplier management functions

As the competition in the market becomes increasingly fierce, the complexity of daily operations of enterprises is also increasing. In order to improve business efficiency and management level, many companies have begun to adopt enterprise resource planning (ERP) systems to centrally manage and integrate various business processes within the organization. This article will introduce in detail how to use PHP to develop a supplier management function based on an ERP system.

System Analysis and Design
Before starting development, we first need to perform system analysis and design. Supplier management functions should include but are not limited to the following aspects: basic supplier information management, supplier partnership management, purchase order management, supplier evaluation and performance appraisal, etc. Through clear requirements analysis and system design, we can better carry out development work.
Database Design and Creation
First, we need to design and create a vendor-managed database. The following are some basic table designs:

Suppliers table (suppliers):

supplier_id (primary key)
supplier_name
supplier_address
supplier_contact

Purchase order table (purchase_orders):

order_id (primary key)
supplier_id (foreign key)
order_date
order_amount

Note: This is just a basic database design example, which can be adjusted and expanded according to needs during actual development.

Page design and development
Next, we started to design and develop the front-end page of the system. The following is a simple example:

a. Supplier list page (suppliers.php):

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>供应商列表</title>
</head>
<body>
    <?php
        // 连接数据库，查询供应商信息
        $conn = new mysqli("localhost", "username", "password", "database");
        $sql = "SELECT * FROM suppliers";
        $result = $conn->query($sql);

        // 输出供应商列表
        if ($result->num_rows > 0) {
            while ($row = $result->fetch_assoc()) {
                echo "供应商ID: " . $row["supplier_id"]. " - 供应商名称: " . $row["supplier_name"]. "<br>";
            }
        } else {
            echo "暂无供应商信息";
        }

        $conn->close();
    ?>
</body>
</html>

Copy after login

b. New supplier page (add_supplier.php):

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>新增供应商</title>
</head>
<body>
    <form action="save_supplier.php" method="post">
        供应商名称：<input type="text" name="supplier_name"><br>
        供应商地址：<input type="text" name="supplier_address"><br>
        供应商联系人：<input type="text" name="supplier_contact"><br>
        <input type="submit" value="保存">
    </form>
</body>
</html>

Copy after login

c. Save the supplier page (save_supplier.php):

<?php
    // 连接数据库，插入新的供应商信息
    $conn = new mysqli("localhost", "username", "password", "database");
    $supplier_name = $_POST["supplier_name"];
    $supplier_address = $_POST["supplier_address"];
    $supplier_contact = $_POST["supplier_contact"];

    $sql = "INSERT INTO suppliers (supplier_name, supplier_address, supplier_contact)
    VALUES ('$supplier_name', '$supplier_address', '$supplier_contact')";

    if ($conn->query($sql) === TRUE) {
        echo "供应商信息保存成功";
    } else {
        echo "供应商信息保存失败";
    }

    $conn->close();
?>

Copy after login

Function implementation and improvement
In addition to the basic supplier list and new supplier functions, we can also Implement other functions according to actual needs, such as modifying and deleting supplier information, etc. By continuously optimizing and improving system functions, supplier management can be made more efficient and convenient.

Summary:
This article briefly introduces how to use PHP to develop a supplier management function based on an ERP system. In the actual development process, issues such as security, data verification, and user rights management also need to be considered. Through reasonable system design and development work, it can help enterprises realize the automation of supplier management and improve overall operational efficiency and management level.
