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;

         }

} 

</script>
