PHP Development Guide for Campus Lost and Property Management System

As university campuses become larger and larger and the flow of people increases, the situation of students losing items in school has also changed. is becoming more and more common. In order to better manage the lost and found situation on campus, it is very necessary to develop a campus lost and found management system. This article will briefly introduce how to use PHP language to develop a simple and practical campus lost property management system, including specific code examples.

First, we need to determine the functional requirements of the system. A simple campus lost and found management system should mainly include the following functions:

1. Students submit lost and found information
2. Students query lost and found information
3. Administrators publish lost and found information
4. The administrator reviews and releases the lost item information submitted by students

Next, we will use PHP language combined with MySQL database to implement these functions. Before starting, make sure you have installed a PHP environment and MySQL database.

The first is database design. We create a database named lost_found, which includes two tables items and users. The items table is used to store lost item information, and the users table is used to store user information. The following are the SQL statements for creating two tables:

CREATE TABLE IF NOT EXISTS `items` (
    `id` INT AUTO_INCREMENT PRIMARY KEY,
    `name` VARCHAR(100) NOT NULL,
    `description` TEXT,
    `lost_or_found` ENUM('lost', 'found') NOT NULL,
    `user_id` INT NOT NULL,
    `status` ENUM('pending', 'approved', 'rejected') NOT NULL DEFAULT 'pending',
    `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE IF NOT EXISTS `users` (
    `id` INT AUTO_INCREMENT PRIMARY KEY,
    `name` VARCHAR(50) NOT NULL,
    `email` VARCHAR(100) NOT NULL,
    `password` VARCHAR(255) NOT NULL
);

The next step is page design. We need to create the following pages:

1. index.php: Home page, where students and administrators can choose the corresponding operations
2. submit.php: where students submit lost item information Page
3. search.php: A page for students to query lost and found information
4. admin.php: A page for administrators to review and publish lost and found information

Among them, submit. php and admin.php require permission verification and can only be accessed by logged in users.

The following is a simple login verification function to verify whether the user is logged in:

session_start();

function is_logged_in() {
    return isset($_SESSION['user_id']);
}

At the top of the submit.php and admin.php pages, we can use this function to verify whether the user is logged in Logged in, if not logged in, jump to the login page.

The following are specific code examples. The following is a code example for the submit lost item information form part of the submit.php page:

<form method="post" action="submit_process.php">
    <label for="name">物品名称：</label>
    <input type="text" name="name" required>

    <label for="description">描述：</label>
    <textarea name="description"></textarea>

    <input type="submit" value="提交">
</form>

In the submit_process.php page, we can receive the data submitted by the form and insert the data into the database:

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $name = $_POST['name'];
    $description = $_POST['description'];
    $user_id = $_SESSION['user_id'];

    // 将数据插入到数据库中
    // 省略插入代码
}

The above code examples are for reference only, and need to be further improved and optimized according to specific needs in actual development.

To sum up, by using PHP language and MySQL database, we can develop a simple and practical campus lost property management system. This system can help students find lost items in time and improve campus management efficiency. Hopefully this article will help readers better understand how to develop a campus lost and found management system.
