php实现客服聊天功能(前台)
这个客服聊天功能是我们做网上书店项目时用到的,它的核心功能是每一个顾客都可以给店主发信息,但是顾客之间不能相互聊天,店主可以跟所有顾客单独聊天,就类似于阿里旺旺:
我们需要用到两张表:用户表和对话表:
首先是顾客登录:
1、布局页面代码以及读取数据代码:
<div id="zhongjian"> <div id="kuangjia" style="height: 550px;width: 620px; margin: 0px auto;border: 1px solid gainsboro;background-color: white;"> <div id="neirong" style="height: 400px;width: 600px;"> <div style="height: 100px;width: 620px;background-image: url(../img/bj4.jpg);"> //取店主用户名,显示店主的头像和姓名<br> <?php $uid = $_SESSION["uid"]; $sql = "select * from users where uid='zhangsan'"; $arr = $db->query($sql); foreach($arr as $v) { echo " <div style='height:100px;float:left;width:100px;float:left;'> <div style='border:2px solid grey;height:84px;width:84px;margin:7px auto; border-radius:10px;overflow:hidden'> <img src='{$v[6]}' height='80px' width='80px'/> </div> </div> <div style='height:100px;width:500px;float:left;'> <div style='height:50px;width:500px;text-align:left;line-height:50px'> 亲爱的店主 </div> <div style='height:50px;width:500px;text-align:left;'>个性签名: <input type='text' placeholder='不读书怎么对得起今天!' style='width:280px'> </div> </div> "; } ?> </div> <div style="height: 300px;width: 620px;overflow: auto;overflow-x:hidden ;"><br> //获取session里存取的uid; <?php $uid = $_SESSION["uid"]; $sql3 = "select * from users where uid='{$uid}'"; $arr3 = $db->query($sql3);<br> //从对话表里读取店主张三和李四所有的对话信息,并按对话时间顺序排序 $sql2="select * from duihua where uid='{$uid}' or jsid='{$uid}' order by dhtime"; $arr2= $db->query($sql2); foreach($arr2 as $n) {<br> //如果是店主,则信息要显示在左侧 if($n[2]=='zhangsan') { echo "<div style='height:100px;width:600px;'> <div style='height:100px;width:250px;float:left'> <div style='height:20px;width:250px;font-size:13px;padding-left:20px'> {$n[6]}</div> <div style='height:80px;width:50px;float:left'> <div style='height:50px;width:50px;margin:0px auto; border-radius:90px;overflow:hidden;'> <img src='{$v[6]}' height='50px' width='50px'/> </div> </div> <div style='min-height:40px;width:200px;float:left;background-color:cornflowerblue; border-bottom-right-radius: 10px;border-top-right-radius: 10px;border-top-left-radius: 40px;border-bottom-left-radius: 40px;'> <p style='padding-left:20px; line-height:40px'> {$n[4]}</p> </div> </div></div>"; } <br>//如果是李四,则显示在右侧 if($n[2]==$uid) { echo "<div style='height:100px;width:600px;margin-right:20px'> <div style='height:100px;width:250px; float:right'> <div style='height:20px;width:250px;font-size:13px;padding-right:20px'> {$n[6]}</div> <div style='height:80px;width:50px;float:right'> <div style='height:50px;width:50px;margin:0px auto; border-radius:90px;overflow:hidden;'> <img src='{$arr3[0][6]}' height='50px' width='50px'/> </div> </div> <div style='min-height:40px;width:200px;float:right;background-color:pink; border-bottom-left-radius: 10px;border-top-left-radius: 10px;border-top-right-radius: 40px;border-bottom-right-radius: 40px;'> <p style='padding-left:20px; line-height:40px'> {$n[4]}</p> </div> </div></div>"; } } ?> </div> </div> <!--id="neirong"--><br> <form role="form"> <div class="form-group"> <textarea class="form-control" rows="3" id="words"></textarea> //输入发送内容 </div> </form> <div id="fs" style="height: 50px; width: 600px;text-align: right; padding-right: 50px;"> <button type="button" class="btn btn-success fasong">发送</button> //点击按钮发送 </div> </div> </div> <!--id=zhongjian-->
实现效果:
2、然后用ajax传值:
<script> $(".tc").click(function(){ $("#kuangjia").show(); }) $(".fasong").click(function(){ var nr=$("#words").val(); $.ajax({ url:"qt-speak-cl.php", data:{words:nr}, type:"POST", dataType:"TEXT", success: function(data){ if(data==1) { window.location.href="qt-dh.php"; } else{ alert("发送内容不能为空!"); } } }) }) $("#dh").click(function(){ $.ajax({ url:"yidu1-cl.php", dataType:"TEXT", success: function(data){ // alert(data); window.location.href="qt-dh.php"; } }) }) </script>
3、qt-speak-cl.php页面:
<?php session_start(); require "DBDA.class.php"; $db = new DBDA(); $uid = $_SESSION["uid"]; $words =$_POST["words"]; $chtime=date("Y-m-d H:i:s",time()); $jieshou = "zhangsan"; if(!empty($words)) { $sql="insert into duihua values ('','{$jieshou}','{$uid}','','{$words}',0,'{$chtime}')"; echo $sql; $db->query($sql,0); } else { echo "发送内容不能为空!"; } ?>
4、yidu1-cl.php:
<?php session_start(); require "DBDA.class.php"; $db = new DBDA(); $uid=$_SESSION["uid"]; $sql = "update duihua set isok='1' where jsid='{$uid}'"; $db->query($sql,0); ?>
