Hi you can create script validation.php like this

```
<?php
//connection is made with database
$con = mysqli_connect("localhost","username",”password”, 'database name');
//when the form is submmited it will insert the values entered by user
if(isset($_POST["submit"]))
{             $uname=$_POST["uname"];
            $pass=$_POST["pass"];
            $name=$_POST["name"];
            $dob=$_POST["year"]."-".$_POST["month"]."-".$_POST["day"];
            $phone=$_POST["phone"];
//It will insert the value in database which is enterd by the user.
$con->query("insert into user_login values('$uname','$pass','$name','$dob',$phone)");
 }
?>
//client side validation
<script>
function validate()
{
//If any of the fields is left empty or null,this function will validate the fields and alerts a message to returns false,to prevent the form being submitted
              var uname=document.forms["myForm"]["uname"].value;
             var uname=document.forms["myForm"]["pass"].value;
             var uname=document.forms["myForm"]["name"].value;
             var uname=document.forms["myForm"]["phone"].value;
   if(uname == null || uname == "" )
             {                         alert("Username must be filled.");
                         return false;
            }
   if (document.getElementById('year').value == 'Select')
           {                        alert("Please select Year");
                       return false;           }
  else if (document.getElementById('month').value == 'Select')
          {
                       alert("Please select Month");
                       return false;
          }
   else if (document.getElementById('day').value == 'Select')
         {                       alert("Please select Day");                       return false;
