PHP development to build an enterprise resource planning (ERP) system with sales contract management functions
With the continuous changes in the market and the expansion of enterprises, enterprises need a comprehensive enterprise resource planning (ERP) system to manage Various business processes and information. Among them, sales contract management is an important part of the enterprise, because the management of the contract is related to the enterprise's sales revenue and customer relations.
This article will introduce how to use PHP language to develop an ERP system with sales contract management functions, and provide some code examples.
1. Requirements Analysis
Before starting development, we need to analyze the requirements for the sales contract management function. Generally speaking, the sales contract management function should include the following aspects:
2. System Design
Before system design, we need to design database tables to store contract information. Suppose we need to store the basic information of the contract, customer information and product information. The following is the design of the database table:
according to the above design, we can start system development.
3. System development
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "erp_system"; $conn = new mysqli($servername, $username, $password, $dbname); if ($conn->connect_error) { die("连接失败: " . $conn->connect_error); } ?>
<?php // 获取表单提交的数据 $contract_id = $_POST['contract_id']; $contract_date = $_POST['contract_date']; $contract_amount = $_POST['contract_amount']; $customer_id = $_POST['customer_id']; // 插入数据到contract表 $sql = "INSERT INTO contract (contract_id, contract_date, contract_amount, customer_id) VALUES ('$contract_id', '$contract_date', '$contract_amount','$customer_id')"; if ($conn->query($sql) === TRUE) { echo "合同录入成功"; } else { echo "Error: " . $sql . "<br>" . $conn->error; } $conn->close(); ?>
<?php // 获取查询条件 $contract_id = $_POST['contract_id']; $customer_name = $_POST['customer_name']; // 拼接查询语句 $sql = "SELECT * FROM contract, customer WHERE contract.customer_id = customer.customer_id AND contract.contract_id = '$contract_id' AND customer.customer_name = '$customer_name'"; $result = $conn->query($sql); if ($result->num_rows > 0) { // 输出查询结果 while($row = $result->fetch_assoc()) { echo "合同编号: " . $row["contract_id"]. " - 合同日期: " . $row["contract_date"]. " - 合同金额: " . $row["contract_amount"]. "<br>"; } } else { echo "查询结果为空"; } $conn->close(); ?>
The above are some code examples. The development of the ERP system with complete sales contract management functions involves more functions and page design. This article just provides a simple example to help readers understand how to use the PHP language for development.
Summary
Sales contract management is an important functional module in the enterprise resource planning (ERP) system. This article uses PHP language for development and introduces the demand analysis, system design and some code examples of the sales contract management function. We hope that readers can gain some understanding and inspiration for the development of ERP systems for sales contract management functions through the introduction of this article.
