email - Add a button that will be redirected to the other webpage in PHP Mailer with HTML design?

I want to add a button that will be redirected to the other webpage when clicked. It also has a token but it says that my token does not exist. I think the link to my button is not working in my HTML in PHP Mailer.

This is the code of my PHP Mailer:

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require '../vendor/autoload.php';

function sendemail_verify($name, $email, $verify_token)
{
    $mail = new PHPMailer(true);                   
        $mail->isSMTP();                                                            
        $mail->SMTPAuth   = true;  
        
        $mail->Host       = 'smtp.gmail.com'; 
        $mail->Username   = '';                 
        $mail->Password   = '';   

        $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;            
        $mail->Port       = 465;                                   
    
        //Recipients
        $mail->setFrom('ust.ofad.appsys@gmail.com', $name);
        $mail->addAddress($email);     
       
        //Content
        $mail->isHTML(true);                                
        $mail->Subject = 'Email Verification';

        $email_template    = '

                                    You recently registered to OFAD-APPSYS with the email, ${email}.
                                </p>
                                <p>You can verify your account by clicking the button below:</p>

                                    If you did not register to OFAD-APPSYS, please ignore

                                </p>
                            </td>
                        </tr>
                    </table>
                </div>
            </center>
        </body>
    </html>
</html>
        ';
        
        $mail->Body = $email_template;
        $mail->send();
        //echo 'Message has been sent.';
    }

And this is the code of my verify.php where the link will be redirected.

<?php
session_start();
include('db.php');

  if(isset($_GET['token']))
  {
    $token = $_GET['token'];
    $verify_query = "SELECT verify_token, verify_status FROM register WHERE verify_token='$token' LIMIT 1";
    $verify_query_run = mysqli_query($conn, $verify_query);

    if (mysqli_num_rows($verify_query_run) > 0) 
    {
          $row = mysqli_fetch_array($verify_query_run);
          if($row['verify_status'] == "0")
          {
            $clicked_token = $row['verify_token'];
            $update_query = "UPDATE register SET verify_status='1' WHERE verify_token = '$clicked_token' LIMIT 1";
            $update_query_run = mysqli_query($conn, $update_query);

                if($update_query_run)
                {
                  $_SESSION['status'] = "Your Account has been verified successfully!";
                  header("Location: verify-success.php");
                  exit(0);
                }
                else 
                {
                  $_SESSION['status'] = "Verification failed!";
                  header("Location: login.php");
                  exit(0);
                }
          }
          else 
          {
            $_SESSION['status'] = "Email already verified. Please Login";
            header("Location: login.php");
            exit(0);
          }
    }
    else 
    {
      $_SESSION['status'] = "This token does not exist.";
      header("Location: login.php");
    }
  }
  else 
  {
    $_SESSION['status'] = "Not Allowed";
    header("Location: login.php");
  }


?>

Solution:

Your link must be somethin like this!

$email_template    = '
       ...
       ...
       ...
      <a href = "http://localhost/appsys/website/verify.php?token='. $verify_token .'">Verify your Email</a>
