How to use PHP for project management and task tracking

Project management and task tracking are an integral part of organizing and managing projects. As a widely used server-side scripting language, PHP has powerful functions and flexible scalability, which can help us achieve project management and task tracking needs. This article will introduce how to use PHP for project management and task tracking, and provide you with some code examples.

Database design and establishing connections

First, we need to design database tables to store project and task information. You can use MySQL or other relational databases to create corresponding tables. Here is a simple example:

CREATE TABLE projects (
    id INT PRIMARY KEY AUTO_INCREMENT,
    title VARCHAR(255) NOT NULL,
    description TEXT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE tasks (
    id INT PRIMARY KEY AUTO_INCREMENT,
    project_id INT,
    title VARCHAR(255) NOT NULL,
    description TEXT,
    status ENUM('todo', 'in_progress', 'completed') DEFAULT 'todo',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (project_id) REFERENCES projects(id)
);

Next, establish a database connection in PHP. The following is a simple database connection example:

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
?>

Add projects and tasks

Next, we need to implement the adding function of projects and tasks. The following is a sample code:

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $title = $_POST["title"];
    $description = $_POST["description"];

    // 添加项目
    $sql = "INSERT INTO projects (title, description) VALUES ('$title', '$description')";
    if ($conn->query($sql) === TRUE) {
        echo "项目添加成功！";
    } else {
        echo "添加项目时出错：" . $conn->error;
    }

    // 添加任务
    $project_id = $conn->insert_id; // 获取刚插入的项目的ID
    $task_title = $_POST["task_title"];
    $task_description = $_POST["task_description"];

    $sql = "INSERT INTO tasks (project_id, title, description) VALUES ('$project_id', '$task_title', '$task_description')";
    if ($conn->query($sql) === TRUE) {
        echo "任务添加成功！";
    } else {
        echo "添加任务时出错：" . $conn->error;
    }
}
?>

Display projects and tasks

Now, we need to implement the function of displaying projects and tasks on the page. The following is a sample code:

<?php
// 获取所有项目
$sql = "SELECT * FROM projects";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "项目标题：" . $row["title"] . "<br>";
        echo "项目描述：" . $row["description"] . "<br>";

        // 获取该项目下的所有任务
        $project_id = $row["id"];
        $sql = "SELECT * FROM tasks WHERE project_id = $project_id";
        $task_result = $conn->query($sql);

        if ($task_result->num_rows > 0) {
            echo "任务列表：<br>";
            while ($task_row = $task_result->fetch_assoc()) {
                echo "- " . $task_row["title"] . "<br>";
                echo "任务描述：" . $task_row["description"] . "<br>";
                echo "任务状态：" . $task_row["status"] . "<br>";
            }
        } else {
            echo "该项目下暂无任务。<br>";
        }

        echo "<br>";
    }
} else {
    echo "暂无项目。";
}
?>
