我們?cè)赑HP頁(yè)面處理html傳過來數(shù)據(jù)，首先要判斷傳過來的數(shù)據(jù)是不是為空，驗(yàn)證碼是不是正確，然后再是往數(shù)據(jù)庫(kù)里面插入我們html傳過來的數(shù)據(jù)

代碼如下

<?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('請(qǐng)輸入你的姓名');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
    exit;
}
if($content==''){
    echo "<script>alert('留言內(nèi)容不能為空');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
    exit;
}
if($vcode!=$_SESSION['VCODE']){
    echo"<script>alert('你的驗(yàn)證碼不正確，請(qǐng)重新輸入');location='".$_SERVER['HTTP_REFERER']. "'</script>";
    exit;
}
$conn=mysqli_connect('localhost','root','root','ressage');
mysqli_set_charset($conn,'utf8'); //設(shè)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('你的留言失敗，請(qǐng)稍后重試');location.href='ressage.php';</script>";
    exit;
}
}else{
    die("數(shù)據(jù)庫(kù)連接失敗".  mysqli_connect_error());
}
