本文实例为大家分享了PHP留言板功能的具体实现代码，供大家参考，具体内容如下

HTML代码

<div class="continer" > <div class="head" style="background-color:rgb(217,237,247);height:50px;vertical-align:middle"><h2 style="color: rgb(81,117,114)">PHP留言本</h2></div> <div class="body"> <volist name="guestbook" id="vo"> <div class="panel"> <div class="panel-head" style="background-color: rgb(223,240,216)"> <span class="nickname" style="color: rgb(104,148,99)">留言者: {$vo.nickname}</span> <span style="color: rgb(104,148,99)">|</span> <span class="email" style="color: rgb(104,148,99)">邮箱: {$vo.email}</span> <span class="time" style="float: right;color: rgb(104,148,99)">时间: {$vo.replytime}</span> </div> <div class="panel-body"> <span class="content">内容: {$vo.content}</span> <span class="time" style="float: right">{$vo.id}楼</span> </div> </div> </volist> </div> <div class="foot"> <form method="post"> <div class="panel" style="background-color: rgb(245,245,245)"> <div class="panel-body" style="padding:30px; width: 20%"> <div class="form-group"> <div class="field field-icon-right"> <input id="nickname" type="text" class="input" name="nickname" placeholder="游客姓名"/> </div> </div> <div class="form-group"> <div class="field field-icon-right"> <input type="text" id="content" class="input" name="content" placeholder="留言内容"/> </div> </div> <div class="form-group"> <span></span> <span class="field"> <input type="text" id="email" class="input" name="email" placeholder="Email"/> </span> </div> <div class="form-group"> <span><button name="liuyan">留言</button></span> <span><button name="restart" onclick="clearDefaultText(this)">重置</button></span> </div> </div> </div> </form> </div></div><script>function clearDefaultText(){ var nickname = document.getElementById('nickname'); var content = document.getElementById('content'); var email = document.getElementById('email'); nickname.value=""; content.value=""; email.value="";}</script>

PHP代码

public function hierarchicalauthority(){ if(isset($_POST['liuyan'])) { $data['nickname']=$_POST['nickname']; $data['content']=$_POST['content']; $data['email']=$_POST['email']; $data['status']=1; $data['replytime']=date('Y-m-d H:i:s',time()); // print_r($data);die(); $user=M('daili_liuyan_guestbook'); $maxid=$user->max('id'); $data['id']=$maxid+1; $user->add($data); // print_r($_POST);die(); } $guestbook = D('daili_liuyan_guestbook')->select(); $this->assign('guestbook',$guestbook); $this->display();}

数据表：(表名为daili_liuyan_guestbook)
