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'>

                        <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'/>

                            <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);
?>
