                                        <div class="group"> <label for="pass" class="label">Password</label> <input id="pass" type="password" name="password_1" class="input" data-type="password" placeholder="Enter your password" required> </div>

                                        <div class="group"> <input type="submit" class="button" value="Sign In"> </div>
                                        <div class="hr"></div>

my php code for the same is

<?php

session_start();
$conn= new mysqli("localhost","root","","yoga");

if($_SERVER["REQUEST_METHOD"]=="POST"){
    $TypeOfRequest=$_POST['for_page'];
    if($TypeOfRequest=="signup"){
        $user=$_POST['username'];
        $pass_1=$_POST['password_1'];
        $pass_2=$_POST['password_2'];
        $mail=$_POST['email'];

    if($pass_1===$pass_2){
        $val=" INSERT INTO yoga_login(username,password_1,password_2,email) VALUES('$user','$pass_1','$pass_2','$mail')";
        if($conn->query($val)===TRUE){
            echo "redirecting to login page.<meta http-equiv='refresh' content='1;login.html'>";
        }else{

            echo "registration unsucessfull";

        }


        }
    if($pass_1!==$pass_2){
        echo "please enter the same password";
    }
    }
    mysqli_close($conn);
}

so is their any other method which doesnt shows the intermediate page like this

Answer 1

Just replace:

echo "redirecting to login page.<meta http-equiv='refresh' content='1;login.html'>";

With the PHP redirect:

header('Location: login.html');
exit;  // this is normally a good idea
