如何在 PHP 页面中实现 WordPress 的评论功能？

// 初始化数据库连接$conn = mysqli_connect("host", "user", "pass", "db_name");// 处理评论提交if (isset($_post['submit'])) {    $name = mysqli_real_escape_string($conn, $_post['name']);    $email = mysqli_real_escape_string($conn, $_post['email']);    $comment = mysqli_real_escape_string($conn, $_post['comment']);    $sql = "insert into comments (name, email, comment) values ('$name', '$email', '$comment')";    mysqli_query($conn, $sql);}// 检索评论$sql = "select * from comments";$result = mysqli_query($conn, $sql);$comments = mysqli_fetch_all($result, mysqli_assoc);// 关闭数据库连接mysqli_close($conn);

<form method="post">    <label for="name">姓名：</label>    <input type="text" name="name" id="name" required>    <label for="email">电子邮件：</label>    <input type="email" name="email" id="email" required>    <label for="comment">评论：</label>    <textarea name="comment" id="comment" required></textarea>    <input type="submit" name="submit" value="提交"></form>

foreach ($comments as $comment) {    echo "<div>";    echo "<strong>{$comment['name']}</strong> ({$comment['email']})";    echo "<p>{$comment['comment']}</p>";    echo "</div>";}
