Using PHP to develop an enterprise resource planning (ERP) system that implements to-do functions

Title: Using PHP to develop an enterprise resource planning (ERP) system that implements to-do list functions

Introduction:
With the continuous expansion of enterprise scale and the increasing complexity of business, enterprises need an efficient Management system to coordinate and manage various resources, so the enterprise resource planning (ERP) system came into being. This article will introduce how to use PHP to develop a to-do list function based on an ERP system and provide corresponding code examples.

1. Project Background
In the daily operations of an enterprise, the work of various departments needs to coordinate and cooperate with each other. For this reason, a system is needed to manage and allocate tasks. The to-do function is usually one of the important components of the ERP system, which can help employees track and complete various tasks efficiently.

2. Technology Selection
PHP is a popular server-side scripting language with a mature ecosystem and rich development resources, so we chose to use PHP to develop the to-do function.

3. Database design
First, we need to design a database to store data related to to-do items. A simple database design is as follows:

1. users table: used to store system user information, including fields such as user ID and name.

tasks table: used to store to-do information, including task ID, user ID, task content, deadline and other fields.

Next, we will use PHP code to implement the to-do function.

1. Query to-do items:

   <?php
   $servername = "localhost";
   $username = "username";
   $password = "password";
   $dbname = "erp_system";
   
   // 创建数据库连接
   $conn = new mysqli($servername, $username, $password, $dbname);
   
   // 检查连接是否成功
   if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
   }
   
   // 查询待办事项
   $sql = "SELECT tasks.ID, users.Name, tasks.Content, tasks.Deadline 
        FROM tasks 
        INNER JOIN users ON tasks.User_ID = users.ID";
   
   $result = $conn->query($sql);
   
   if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["ID"]. " - 用户: " . $row["Name"]. " - 内容: " . $row["Content"]. " - 截止日期: " . $row["Deadline"]. "<br>";
    }
   } else {
    echo "0 结果";
   }
   
   // 关闭数据库连接
   $conn->close();
   ?>

2. Add to-do items:

   <?php
   $servername = "localhost";
   $username = "username";
   $password = "password";
   $dbname = "erp_system";
   
   $content = $_POST["content"];
   $deadline = $_POST["deadline"];
   $user_id = $_POST["user_id"];
   
   // 创建数据库连接
   $conn = new mysqli($servername, $username, $password, $dbname);
   
   // 检查连接是否成功
   if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
   }
   
   // 添加待办事项
   $sql = "INSERT INTO tasks (User_ID, Content, Deadline)
        VALUES ('$user_id', '$content', '$deadline')";
   
   if ($conn->query($sql) === TRUE) {
    echo "待办事项添加成功";
   } else {
    echo "Error: " . $sql . "<br>" . $conn->error;
   }
   
   // 关闭数据库连接
   $conn->close();
   ?>

3. Delete to-do items Do items:

   <?php
   $servername = "localhost";
   $username = "username";
   $password = "password";
   $dbname = "erp_system";
   
   $task_id = $_POST["task_id"];
   
   // 创建数据库连接
   $conn = new mysqli($servername, $username, $password, $dbname);
   
   // 检查连接是否成功
   if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
   }
   
   // 删除待办事项
   $sql = "DELETE FROM tasks WHERE ID='$task_id'";
   
   if ($conn->query($sql) === TRUE) {
    echo "待办事项删除成功";
   } else {
    echo "Error: " . $sql . "<br>" . $conn->error;
   }
   
   // 关闭数据库连接
   $conn->close();
   ?>

5. Summary

By using PHP development, we can easily implement the enterprise resource planning (ERP) system with to-do list functions. This article provides database design examples and related PHP code to help readers understand how to use PHP for development. Of course, actual ERP systems will be more complex, but the examples provided in this article can serve as a basis for initially implementing to-do functionality. I hope this article will be helpful to readers in developing the to-do function in ERP systems.
