Simple comment Box System using php

Hi ,I am going to explain about how to create simple comment box system using php. The comment system one of the important thing for blog or website because the user comments is publicly visible to all. Each and every customers know about others comments about the particular post or pages.

Most of the members using this comment box system for blog post. Another important thing is to validate the particular form fields to avoid unformulated data from the customer.

<?php
include('connect.php');
$select=mysql_query("select * from commentbox");
while($row=mysql_fetch_array($select))
{
echo "<div id='upstyle'>";
echo "<img src='man.png'"."' width='50px' height='50px' align='left' />";
echo "<div id='commname'>".$row['name']."</div>";
echo "<div id='commcomment'>".$row['comments']."</div>";
echo "</div><br />";
}
?>
<script type="text/javascript">
function validation()
{
var name=document.comment.name.value;//document.getElementById('name').value
if(name=="")
{
alert('Please Enter Your Name First');
//document.getElementById('san').innerHTML="please enter the name";
document.comment.name.focus();
return false;
}
var desig=document.comment.desig.value;
if(desig=="")
{
alert('Plese Enter Your Designation');
document.comment.desig.focus();
return false;
}
var email=document.comment.email.value;
if(email=="")
{
alert('Please Enter your Email ID');
document.comment.email.focus();
return false;
}
else
{
var ex=/^(([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4}))$/;
 if(ex.test(email)==false)
 {
  alert('Please Enter Valid Email ID');
document.comment.email.focus();
return false;
 }
}
/*<!--else

var pra=/^([0-9_\-\.\+\,])$/;
if(pra.test(email)==false)
{
alert('Enter Correct Contact Number');
document.comment.email.focus();
return false;
