PHP+Mysql+Ajax method to implement Taobao customer service Aliwangwang chat function (front page)

This article mainly introduces the use of php mysql ajax to implement the front-end page of Taobao customer service Aliwangwang chat function. It is very good and has reference value. Friends in need can refer to it

First of all, let’s take a look at what I have done Realized renderings:

Consumer page: (this essay)

(1) The shop owner’s avatar will be displayed

(2) The information sent by the current user is displayed on the right side, the accepted information is displayed on the left

Store owner or customer service page: (next essay)

(1) There is a on the left The list will display all the customers who have talked with the store owner; the list can be moved; it will prompt when there is a new message; the chat history can also be cleared

(2) Click on the customer in the list to enter the dialog box on the right. Display the chat information with the customer

Before implementing the function, let’s talk about the two tables I used:

Explain: bkid is not used here; the isok column is used to determine whether the message has been read, and unread is 0;

Now, let’s talk about the steps: (divided into two parts: frontend and backend )

In this essay, let’s first talk about how the front-end page is implemented: (Li Si logs in)

Use session to access lisi ;It is convenient to retrieve data from the user table later

1, layout page code and read data code:

Achievement effect:

2. Ajax code when clicking send:

<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" rel="external nofollow" rel="external nofollow" ; 
    }
    else{
     alert("发送内容不能为空！");
    }
    }
  })
 }) 
  $("#dh").click(function(){
  $.ajax({
   url:"qt-yidu-cl.php",
   dataType:"TEXT",
   success: function(data){
//    alert(data);     
    window.location.href="qt-dh.php" rel="external nofollow" rel="external nofollow" ;    
   }   
  })
 })
</script>

3. qt-speak-cl.php Page:

<?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))
{
$sql="insert into duihua values (&#39;&#39;,&#39;{$jieshou}&#39;,&#39;{$uid}&#39;,&#39;&#39;,&#39;{$words}&#39;,0,&#39;{$chtime}&#39;)";
echo $db->query($sql,0);
<em id="__mceDel">}
else
{ 
 echo "发送内容不能为空！";
}
?>
</em>

If the content sent is empty, it will prompt "The content sent cannot be empty!"

The front page will display different information as different users log in; let Wang Wu log in to see:
