PHP example-PHP+Mysql+Ajax implements Taobao customer service or 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 or Aliwangwang chat function. It is very good and has reference value. Friends who need it can refer to it

First look at Here is the rendering I have achieved:

Consumer page: (this essay)

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

(2) The current user sends information Displayed on the right, accepted information is displayed on the left

Store owner or customer service page: (next essay)

(1) on the left There is a list on the side that 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; you can also clear the chat history

(2) Click on the customer in the list to enter the conversation on the right Box interface to display the chat information with the customer

Before implementing the function, let me 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 front desk and Two parts of the backend)

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

Use session to save Take lisi; it will be easier to get 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 sending content is empty, it will prompt "Send content It cannot be empty! ”

The front page will display different information according to different user login; let Wang Wu log in to see:
