Remove element from DOM after submit

I am selecting data from my db and store them in a list in bahn.php. Then I echo the values of the objects to display them in index.php.

Now, I want to update the status of the displayed object by clicking on the “accept”-button. This is working so far, but I have to reload the page manually to get a new created list without the updated object. What do I need to do to just click on accept and the list gets refreshed by itself?

I tried to reload location, header location etc. after my submit, but then the update did not work.

bahn.php

<?php

require_once("config.php");
require("bahn.php");

function get_bahn() {
    $bahn_list = array();
    $db = db_connection();
    $statement = $db->prepare(
        "SELECT bahn.bahnid ... FROM bahn WHERE bahn.status = 0");
    $statement->execute();
    while($row = $statement->fetch()) {
        $new_bahn = new bahn(...);
        array_push($bahn_list, $new_bahn);
    }
    return $bahn_list;
}
function create_bahn_list($bahn_list) {
        if (empty($bahn_list)) {
            echo '<div class="alert alert-danger fade show">
            ...
          </div>';
        } else {
            foreach($bahn_list as $key => $val) {

                $statusid = $val->get_bahnid();

                echo '...
                
              <button type="button" class="btn btn-primary btn-sm" data-bs-toggle="modal" data-bs-target="#info'.$val->get_bahnid().'"> More info</button>
                <div class="modal fade" id="info'.$val->get_bahnid().'" tabindex="-1" aria-hidden="true">
                 <div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
                  <div class="modal-content">

                    ...

                    <div class="modal-footer">
                        <form method="POST">
                            <button type="submit" name="accept" class="btn btn-success btn-sm">Accept</button>
                        </form>
                     </div>
    
                    ...';       
            }
        }

        if(isset($_POST['accept'])) {
            $db = db_connection();
            $statement = $db->prepare(
                "UPDATE bahn
                SET status = 1
                WHERE bahn.bahnid = $statusid");
            $statement->execute();
                
            }
    }
