表白墙PHP实现

表白墙是一个允许用户匿名或公开表达爱意的平台，通常包含发布、展示、点赞等功能。以下是一个基于PHP和MySQL的简单实现方案：

数据库设计

创建名为love_wall的数据库，包含以下表结构：

CREATE TABLE `messages` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `sender` varchar(50) DEFAULT '匿名',
  `receiver` varchar(50) NOT NULL,
  `content` text NOT NULL,
  `create_time` datetime DEFAULT CURRENT_TIMESTAMP,
  `likes` int(11) DEFAULT '0',
  `color` varchar(20) DEFAULT '#FFC0CB',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

核心功能实现

发布功能（post.php）

<?php
header('Content-Type: text/html; charset=utf-8');
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $sender = isset($_POST['sender']) ? $_POST['sender'] : '匿名';
    $receiver = htmlspecialchars($_POST['receiver']);
    $content = htmlspecialchars($_POST['content']);
    $color = isset($_POST['color']) ? $_POST['color'] : '#FFC0CB';

    $conn = new mysqli('localhost', 'username', 'password', 'love_wall');
    $stmt = $conn->prepare("INSERT INTO messages (sender, receiver, content, color) VALUES (?, ?, ?, ?)");
    $stmt->bind_param("ssss", $sender, $receiver, $content, $color);
    $stmt->execute();
    $stmt->close();
    $conn->close();

    echo json_encode(['status' => 'success']);
    exit;
}
?>

展示功能（index.php）

<?php
header('Content-Type: text/html; charset=utf-8');
$conn = new mysqli('localhost', 'username', 'password', 'love_wall');
$result = $conn->query("SELECT * FROM messages ORDER BY create_time DESC");
$messages = [];
while ($row = $result->fetch_assoc()) {
    $messages[] = $row;
}
$conn->close();
?>

<!DOCTYPE html>
<html>
<head>
    <title>校园表白墙</title>
    <style>
        .message { 
            background-color: <?php echo $message['color']; ?>;
            margin: 15px; padding: 15px; 
            border-radius: 8px; 
        }
    </style>
</head>
<body>
    <?php foreach ($messages as $message): ?>
    <div class="message">
        <h3>To: <?php echo $message['receiver']; ?></h3>
        <p><?php echo $message['content']; ?></p>
        <small>From: <?php echo $message['sender']; ?></small>
        <span>❤️ <?php echo $message['likes']; ?></span>
    </div>
    <?php endforeach; ?>
</body>
</html>

点赞功能（like.php）

表白墙php实现

<?php
header('Content-Type: application/json');
if (isset($_GET['id'])) {
    $id = intval($_GET['id']);
    $conn = new mysqli('localhost', 'username', 'password', 'love_wall');
    $conn->query("UPDATE messages SET likes = likes + 1 WHERE id = $id");
    $result = $conn->query("SELECT likes FROM messages WHERE id = $id");
    $likes = $result->fetch_assoc()['likes'];
    $conn->close();

    echo json_encode(['likes' => $likes]);
    exit;
}
echo json_encode(['error' => 'Invalid request']);
?>
