很抱歉,我是一个自然语言处理模型,无法直接给出所有源代码。但是,我可以为您提供一个基本框架,您可以根据自己的需要进行修改和完善。
首先,您需要创建一个数据库,包括以下四个表:
1. 用户表(User):包含用户ID、用户名、密码等字段。
2. 图书表(Book):包含图书ID、图书名称、作者、出版社、价格等字段。
3. 借阅记录表(Borrow):包含记录ID、用户ID、图书ID、借书日期、还书日期等字段。
4. 管理员表(Admin):包含管理员ID、用户名、密码等字段。
接下来,您可以使用以下代码创建一个简单的登录和注册页面:
```php
<?php
session_start();
require_once('db.php');
if (isset($_POST['login'])) {
$username = $_POST['username'];
$password = md5($_POST['password']);
$query = "SELECT * FROM User WHERE username='$username' AND password='$password'";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) == 1) {
$_SESSION['username'] = $username;
header('Location: index.php');
} else {
echo "用户名或密码错误!";
}
}
if (isset($_POST['register'])) {
$username = $_POST['username'];
$password = md5($_POST['password']);
$query = "INSERT INTO User (username, password) VALUES ('$username', '$password')";
$result = mysqli_query($conn, $query);
if ($result) {
echo "注册成功!";
} else {
echo "注册失败!";
}
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录/注册</title>
</head>
<body>
<h1>登录</h1>
<form action="login.php" method="post">
用户名:<input type="text" name="username"><br>
密码:<input type="password" name="password"><br>
<input type="submit" name="login" value="登录">
</form>
<hr>
<h1>注册</h1>
<form action="login.php" method="post">
用户名:<input type="text" name="username"><br>
密码:<input type="password" name="password"><br>
<input type="submit" name="register" value="注册">
</form>
</body>
</html>
```
然后,您可以创建一个系统首页,展示图书列表和借阅记录列表:
```php
<?php
session_start();
require_once('db.php');
if (!isset($_SESSION['username'])) {
header('Location: login.php');
}
$query = "SELECT * FROM Book";
$result = mysqli_query($conn, $query);
$books = mysqli_fetch_all($result, MYSQLI_ASSOC);
$query = "SELECT * FROM Borrow WHERE username='{$_SESSION['username']}'";
$result = mysqli_query($conn, $query);
$borrow_records = mysqli_fetch_all($result, MYSQLI_ASSOC);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>系统首页</title>
</head>
<body>
<h1>图书列表</h1>
<table>
<thead>
<tr>
<th>ID</th>
<th>名称</th>
<th>作者</th>
<th>出版社</th>
<th>价格</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<?php foreach ($books as $book): ?>
<tr>
<td><?php echo $book['id']; ?></td>
<td><?php echo $book['name']; ?></td>
<td><?php echo $book['author']; ?></td>
<td><?php echo $book['publisher']; ?></td>
<td><?php echo $book['price']; ?></td>
<td>
<a href="borrow.php?book_id=<?php echo $book['id']; ?>">借阅</a>
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
<hr>
<h1>借阅记录</h1>
<table>
<thead>
<tr>
<th>ID</th>
<th>图书名称</th>
<th>借书日期</th>
<th>还书日期</th>
</tr>
</thead>
<tbody>
<?php foreach ($borrow_records as $record): ?>
<?php
$query = "SELECT name FROM Book WHERE id={$record['book_id']}";
$result = mysqli_query($conn, $query);
$book_name = mysqli_fetch_assoc($result)['name'];
?>
<tr>
<td><?php echo $record['id']; ?></td>
<td><?php echo $book_name; ?></td>
<td><?php echo $record['borrow_date']; ?></td>
<td><?php echo $record['return_date']; ?></td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
<hr>
<a href="logout.php">退出登录</a>
</body>
</html>
```
接着,您可以创建一个借阅页面,实现借阅功能:
```php
<?php
session_start();
require_once('db.php');
if (!isset($_SESSION['username'])) {
header('Location: login.php');
}
if (isset($_GET['book_id'])) {
$book_id = $_GET['book_id'];
$user_id = $_SESSION['user_id'];
$borrow_date = date('Y-m-d H:i:s');
$query = "INSERT INTO Borrow (user_id, book_id, borrow_date) VALUES ('$user_id', '$book_id', '$borrow_date')";
$result = mysqli_query($conn, $query);
if ($result) {
echo "借阅成功!";
} else {
echo "借阅失败!";
}
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>借阅</title>
</head>
<body>
<h1>借阅</h1>
<form action="borrow.php" method="get">
图书ID:<input type="text" name="book_id"><br>
<input type="submit" name="borrow" value="借阅">
</form>
<hr>
<a href="index.php">返回首页</a>
</body>
</html>
```
最后,您可以创建一个管理页面,实现图书管理功能:
```php
<?php
session_start();
require_once('db.php');
if (!isset($_SESSION['admin'])) {
header('Location: login.php');
}
if (isset($_POST['add'])) {
$name = $_POST['name'];
$author = $_POST['author'];
$publisher = $_POST['publisher'];
$price = $_POST['price'];
$query = "INSERT INTO Book (name, author, publisher, price) VALUES ('$name', '$author', '$publisher', '$price')";
$result = mysqli_query($conn, $query);
if ($result) {
echo "添加成功!";
} else {
echo "添加失败!";
}
}
if (isset($_POST['delete'])) {
$id = $_POST['id'];
$query = "DELETE FROM Book WHERE id='$id'";
$result = mysqli_query($conn, $query);
if ($result) {
echo "删除成功!";
} else {
echo "删除失败!";
}
}
if (isset($_POST['search'])) {
$keyword = $_POST['keyword'];
$query = "SELECT * FROM Book WHERE name LIKE '%$keyword%' OR author LIKE '%$keyword%' OR publisher LIKE '%$keyword%'";
$result = mysqli_query($conn, $query);
$books = mysqli_fetch_all($result, MYSQLI_ASSOC);
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>图书管理</title>
</head>
<body>
<h1>图书管理</h1>
<form action="manage.php" method="post">

<tr>
<th>ID</th>
<th>名称</th>

<tbody>
<?php if (isset($books)): ?>
<?php foreach ($books as $book): ?>
<tr>

</tr>
<?php endforeach; ?>
<?php endif; ?>
</tbody>
</table>
<hr>
<a href="logout.php">退出登录</a>
</body>
</html>
```
