Updating table using PHP, HTML and MySQL

Question

I am trying to update a table in my database with PHP.

I used a loop to get all of the data from the table. Then, adding an "Approve" button in front of each row where the user can click if they want to approve the request, which would change the status to Approved.

Now I'm stuck, I can't find a way to update the Status field and I am not good with JavaScript.

I thought about making the button name dynamic, but I couldn't.

This is the loop code:

while($row = mysqli_fetch_array($result))
  {

echo "<tr bgcolor='#cccccc'>";
echo "<td>" . $row['nursename'] . "</td>";
echo "<td>" . $row['dr'] . "</td>";
echo "<td>" . $row['natureofreq'] . "</td>";
echo "<td>" . $row['clinic'] . "</td>";
echo "<td>" . $row['clinicfloor'] . "</td>";
echo "<td>" . $row['qitem'] . "</td>";
echo "<td>" . $row['moreinfo'] . "</td>";
echo "<td>" . $row['user_check'] . "</td>";
echo "<td>" . $row['id'] . "</td>";
echo "<td bgcolor='#009FE3'>" . $row['rstatus'] . "</td>";
echo '<form name="submit" method="post" action="">';
echo "<td>" . '<button id="approve" name="approve"> Approve</button>' . "</td>";
echo '</form>';
echo "</tr>";
}

This is the update code, which is not working:

$id=$row['id'];
if(isset($_POST['approve']))
{
  $allowed = mysqli_query($n," UPDATE newrequest SET rstatus = 'Approved' WHERE id = '$id' ");
}

I would appreciate any help.

     $url_of_current_page = $_SERVER['REQUEST_URI'];

     if(isset($url_of_current_page)){

         $_SESSION['url_of_current_page'] = $url_of_current_page;

     }

     $approve_row = '';

     while($row = mysqli_fetch_array($result)){

         $approve_row .= "<tr bgcolor='#cccccc'>

                             <td>" . $row['nursename'] . "</td>

                             <td>" . $row['dr'] . "</td>

                             <td>" . $row['natureofreq'] . "</td>

                             <td>" . $row['clinic'] . "</td>

                             <td>" . $row['clinicfloor'] . "</td>

                             <td>" . $row['qitem'] . "</td>

                             <td>" . $row['moreinfo'] . "</td>

                             <td>" . $row['user_check'] . "</td>

                             <td bgcolor='#009FE3'>" . $row['rstatus'] . "</td>

                             <td>
                                 <a href='action.php?id=" . $row['id'] . "'>
                                     <button>Approve</button>
                                 </a>
                             </td>

                         </tr>";

    }


     if(isset($approve_row)){

          echo $approve_row;

     }

And the action code. If your action page is not action.php, then tell me the name of the page.

     if(isset($_GET['id'])){

         $id = $_GET['id'];

         mysqli_query($n," UPDATE newrequest SET rstatus = 'Approved' WHERE id = '$id' ");

         if(isset($_SESSION['url_of_current_page'])){

              header( "Location: ". $_SESSION['url_of_current_page'] );
              exit();

         }
     }
