I have searched and tested different solutions all day without luck. In the below code I want (when clicked) to set a session on the "open" links I echo in the foreach loop. I tried using AJAX but I am new to AJAX and could not make it work. I know how to do it using GET but it is too risky, so i welcome your suggestion and preferably examples.

$task_array = array_combine($task_id_unique, $task_status);
                foreach ($task_array as $card_nr => $card_status) {
                ?>
                    <table>
                      <tr>
                        <th>card nr.</th>
                        <th>Status</th>
                        </tr>
                        <td><?php
                                        echo $card_nr;?></td>
                        <td>
                   <?php
                            if ($card_status == true) {
                                    echo "<a href=workcard.php>Open</a>";
                            }
                            else echo "Done ". $card_nr;?></td>
                    </table>

What have you tried and what doesn't work, because this looks like what you need...

HTML:

<a href="home.php?a=register">Register Now!</a>

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

    $_SESSION['link']= 'whatever';

 }

And if you need to do it without a page refresh, then use AJAX.
