<script language="javascript" type="text/javascript">
function Validation()
{
if(document.getElementById("name").value=="")
{
document.getElementById("nameerr").innerHTML="Enter Name";
document.getElementById("name").style.backgroundColor = "yellow";
}
else
{
document.getElementById("nameerr").innerHTML="";
document.getElementById("name").style.backgroundColor = "White";
}
if(document.getElementById("email").value=="")
{
document.getElementById("emailerr").innerHTML="Enter Email";
document.getElementById("email").style.backgroundColor = "yellow";
}
else
{
document.getElementById("emailerr").innerHTML="";
document.getElementById("email").style.backgroundColor = "White";
}
if(document.getElementById("phone").value=="")
{
document.getElementById("phoneerr").innerHTML="Enter Contact No";
document.getElementById("phone").style.backgroundColor = "yellow";
}
else
{
document.getElementById("phoneerr").innerHTML="";
document.getElementById("phone").style.backgroundColor = "White";
}
if(document.getElementById("society").value=="")
{
document.getElementById("societyerr").innerHTML="Enter Society";
document.getElementById("society").style.backgroundColor = "yellow";
}
else
{
document.getElementById("societyerr").innerHTML="";
document.getElementById("society").style.backgroundColor = "White";
}
if(document.getElementById("occupation").value=="")
{
document.getElementById("occupationerr").innerHTML="Enter Occupation";
document.getElementById("occupation").style.backgroundColor = "yellow";
}
else
{
document.getElementById("occupationerr").innerHTML="";
document.getElementById("occupation").style.backgroundColor = "White";
}
if(document.getElementById("feedback").value=="")
{
document.getElementById("feedbackerr").innerHTML="Enter Feedback";
document.getElementById("feedback").style.backgroundColor = "yellow";
}
else
{
document.getElementById("feedbackerr").innerHTML="";
document.getElementById("feedback").style.backgroundColor = "White";
}
if(document.getElementById("name").value=="" || document.getElementById("email").value==""
|| document.getElementById("phone").value=="" || document.getElementById("society").value==""
|| document.getElementById("occupation").value=="" || document.getElementById("feedback").value=="")
return false;
else
return true;
}
</script>
<?php
if(isset($_POST['submit']))
{
$conn = mysql_connect('localhost','root','');
mysql_select_db('society_f',$conn);
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$society = $_POST['society'];
$occupation = $_POST['occupation'];
$feedback = $_POST['feedback'];
$qry = "insert into feedback values(null". ",'" . $name . "','" . $email . "','" . $phone . "','" . $society . "','" . $occupation . "','" . $feedback . "')" ;
$res = mysql_query($qry);
