How to do some javascript functions after redirecting page to a new url

  header('Location: ../homepage.html');
  echo "<script language='javascript'> console.log('Email already exists'); </script>";
  echo "<script> console.log('ccccc'); </script>";

I am just trying to create a registration form. When user tries to register with same Email Id, I want to go back to my html page and open login window[Trigger login click].

For initial try, i just try to console some strings after redirecting the page. I don't get those strings.

If i comment out header line, I get those two strings.

How do i solve this issue? Is there any alternative for my scenario?

I have separate html and php files.

EDIT:

if (mysqli_num_rows($result1) > 0)
   {
        //echo "This Email is already used.";
        //Write code to go back to register window
        /*echo '<script type="text/javascript">
                console.log("cdsafcds");
                $(".login_links_login").trigger("click");
                </script>';*/
        $_SESSION['email_exist']="Email Already Exists";
        header('Location: ../homepage.php');
   }

homepage.php Part:

 <?php
 if(isset($_SESSION['email_exist']))
 {
   echo "<script language'javascript'>conosle.log('Me');</script>";
 }
 ?>

 <html>
 <head>
 .......
 <form class="right registerForm" id="registerForm" method="POST" action="lib/registration_validate.php">
 ......

when you use header('Location: ../homepage.php'); it wont execute the two lines afterward. That is the whole problem. You can do it either by passing variables through header like this : header('Location: ../homepage.php?log'); or setting session in your php script and use redirect afterwards.

You also need php file in order to catch the parameter you just send and use if like this :

if(isset($_GET['log'])){
   echo "<script language='javascript'> console.log('Email already exists'); </script>";
  echo "<script> console.log('ccccc'); </script>";
}

or :

if(isset($_SESSION['log'])){
       echo "<script language='javascript'> console.log('Email already exists'); </script>";
      echo "<script> console.log('ccccc'); </script>";
    }

It depends on what method you used earlier. So turn your homepage.html into homepage.php and put it there.
