I have a form that have a select input, and there's another pop up that sets a session. i want to save the selected values while the page reloading for the session setting is there's any solution for that ?
example of my code
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<form method="post" action="">
    <select name="first">
    <option value="example1">first opt</option>
    <option value="example2">second opt</option>
    </select>
    <input type="submit" value="Done">
    </form>
    <p>you have added > <?php echo $_SESSION['sessionset']; ?></p>
    <button data-toggle="modal" data-target="#myModal">Adding something by setting a session</button>
    
    
    <div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">
 <button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
   <form method="post" action="">
    <select name="sessionset">
    <option value="cupcake">cupcake</option>
    <option value="cookie">cookie</option>
    </select>
    <input type="submit" value="Done">
    </form>
  
  </div>
  </div>php
 if(isset($_POST['sessionset'])) {
        $_SESSION['sessionset'] = $_POST['sessionset'];
    }
this is a little example of my page, now i need to set the session and i don't want the user to reset his select because of the reload
