<?php
session_start();
header("content-type:text/html;charset=utf-8");
$name=$_POST['name'];
$email=$_POST['email'];
$content=$_POST['content'];
$vcode=$_POST['vcode'];
//if($name==''){
//    echo "<script>alert('请输入你的姓名');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
//    exit;
//}
//if($content==''){
//
//    echo "<script>alert('留言内容不能为空');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
//    exit;
//
//}
//if($vcode!=$_SESSION['VCODE']){
//
//    echo"<script>alert('你的验证码不正确，请重新输入');location='".$_SERVER['HTTP_REFERER']. "'</script>";
//    exit;
//}
$conn=mysqli_connect('localhost','root','root','ressage');
mysqli_set_charset($conn,'utf8'); //设定字符集
if($conn){
    $sql=mysqli_prepare($conn,"insert into ressage_user(name,email,content,ressage_time) VALUES (?,?,?,now())");
    $param=mysqli_stmt_bind_param($sql,'sss',$name,$email,$content);
    $result=mysqli_stmt_execute($sql);
if($result){
    echo "<script>alert('留言成功');location.href='ressage.php';</script>";
}else{
    echo"<script>alert('你的留言失败，请稍后重试');location.href='ressage.php';</script>";
    exit;
}
}else{
    die("数据库连接失败".  mysqli_connect_error());
}
?>
