phpcms 调用点击数

document.addEventListener('DOMContentLoaded', function() {
    var url = '/api/increase_click_count.php';
    fetch(url, {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ content_id: 123 })
    });
});

<?php
// 假设使用 MySQL 数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "phpcms";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

$content_id = $_POST['content_id'];

// 更新点击数
$sql = "UPDATE content SET click_count = click_count + 1 WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $content_id);
$stmt->execute();
