[html]

<!doctype html> <html lang="en"> <head>     <meta charset="utf-8" />     <title>chatbox</title>     <script src="http://code.jquery.com/jquery-1.11.3.min.js" charset="utf-8"></script>     <script>         $(document).ready(function(){             $("#content").load("ajaxload.php");              $("a.btn").click(function(){                 $.post('ajaxpost.php', $('#userarea').serialize(), function(data){                         $('#content').append('<p>'+data+'</p>');                 });                 return false;             });          });     </script>     <script src="chatbox.js" charset="utf-8"></script>     <link href='http://fonts.googleapis.com/css?family=indie+flower' rel='stylesheet' type='text/css'>     <link href='http://fonts.googleapis.com/css?family=open+sans' rel='stylesheet' type='text/css'>     <link rel="stylesheet" href="chatbox.css" title="chatbox" type="text/css" media="screen" charset="utf-8"> </head> <body>     <h1 id="swegre">         swegre<span>&copy;</span>     </h1>     <div id="wrapper">         <h1>leave comment!</h1>         <div id ="content">             <p style="background-color: #b7b7b7">admin: here's our chatbox</p>         </div>          <div id="message">             <form id="userarea">             <textarea id="textareamsg" name="messages" rows="2" cols="30" required=""></textarea>             <a href="#" class="btn">post</a>             </form>         </div>      </div> </body> </html>

[css not important] [jquery]

$(document).ready(function(){             $( "a.btn" ).click(function() {                 var textvalue = $('textarea#textareamsg').val();                 if(textvalue == "" || textvalue == " " || textvalue == "  " || textvalue == "   "){                     alert('you have write in textarea post message');                     return false;                 }else{             $('#content').append("<p>you: " + textvalue + "</p>");             $('textarea#textareamsg').val('');             }             });         });

[ajaxload.php]

<?php //conection: $link = mysqli_connect("localhost","root","123","chat") or die("error " . mysqli_error($link));  //consultation:  $query = "select * messages" or die("error in consult.." . mysqli_error($link));  //execute query.  $result = mysqli_query($link, $query);  //display information:  while($row = mysqli_fetch_array($result)) {   echo '<p class="other">';   echo $row ["message"] . '</p>'; } ?>

[ajaxpost]

<?php $link = mysqli_connect("localhost","root","123","chat") or die("error " . mysqli_error($link));  //consultation:  $query = "select * messages" or die("error in consult.." . mysqli_error($link));  //execute query.  $result = mysqli_query($link, $query);  //code goes here  $message = $_post['messages'];  mysqli_query($link,"insert messages (message) values ('$message')"); ?>

use ajax reload chat div.

steps

1. make chat div 2. make  ajax call every 10 sec 3. design  new page called chat.php 4. update chat data per db.

moral: call ajax every 10 sec
