PHP development small forum tutorial post reply-2

Create reply_post.php file

This page stores the data passed from the reply page into the database

The code is as follows

<?php
header("Content-type:text/html;charset=utf-8");    //设置编码
// 创建连接
$conn = mysqli_connect("localhost", "root", "root", "mybbs");
mysqli_set_charset($conn,'utf8'); //设定字符集
$id=$_GET['id'];
$reply_author=$_POST['reply_author'];
$reply=$_POST['reply'];
$reply_time=date("Y-m-d H:i:s");
$sql="update tiopic set reply_author='$reply_author',reply='$reply',reply_time='$reply_time' WHERE id='$id'";
$que=mysqli_query($conn,$sql);
if($que){
    echo "<script>alert('回复成功');location.href='thread.php?id=1';</script>";
}else{
    echo "<script>alert('你的回复好像有点小问题.....');location.href='thread.php';</script>";
}
?>

This way we have the basic functions of our forum, and the referrer can add administrator permissions to the original basis
