    <p>I am having some trouble with setting up a pretty small application. It's going to be a little survey.</p> <p>The form is split into two pages. After submitting the first one, the data is stored in the <code>$_SESSION</code> array with this:</p> <pre><code>save_items(array('my_data' =&gt; $my_data_oject)); </code></pre> <p>The function <code>save_items()</code> looks like this:</p> <pre><code>function save_items(array $array) { foreach ($array as $name =&gt; $item) { $_SESSION[$name] = $item; } } </code></pre> <p>Then I <code>unset($_POST)</code> and redirect like this:</p> <pre><code>header('Location: index.php?action=survey_part2'); exit; </code></pre> <p>My problem is: After redirection, the previously stored login data is still in the <code>$_SESSION</code>, but <code>my_data_object</code> is not. If I avoid the redirection, I can see that <code>my_data_object</code> is stored in the <code>$_SESSION</code> array before the redirection starts. So the combination of <code>header()</code> and <code>exit</code> seems to destroy the session in part. Does anybody know how this can happen?</p> <p>Finally, parts of my controller:</p> <pre><code>&lt;?php error_reporting(E_ALL); session_start(); require_once 'models/functions.php'; require_once 'models/classes.php'; $action = isset($_REQUEST['action']) ? $_REQUEST['action'] : NULL; $view = $action; $language = isset($_REQUEST['lang']) ? $_REQUEST['lang'] : 'de'; switch ($action) { case 'login' : if ((!empty($_POST['email'])) &amp;&amp; (!empty($_POST['password']))) { $user = new User(); $login = $user-&gt;find_user($_POST); if (!empty($login)) { set_message('Welcome ' . $login['Firstname'] . ' ' . $login['Lastname'] . '!'); save_items(array('user_id' =&gt; $login['CID'])); unset($_POST); redirect("index.php?action=survey&amp;lang=de"); //&lt;- works fine. Login is kept, Message is kept. } else { set_message('Please try again.'); unset($_POST); } } else { unset($_POST); set_message('Try again.'); } break; /* ... shortage */ case 'survey' : check_login(); //&lt;- doesn't matter if (empty($_POST)) { /* ... shortage */ } else { /* ... creation of my_data_object + setting one more message */ save_items(array('my_data' =&gt; $my_data_object)); unset($_POST); save_items(array('test' =&gt; 'you see me?')); //&lt;- index.php?action=survey_2 won't get it //var_dump($_SESSION); header('Location: index.php?action=survey_2&amp;lang=de'); //&lt;- does not work. Login is kept in $_SESSION, but not my_data exit; } break; </code></pre> <p>Thanks!</p> <p>This topic is maybe similar to <a href="https://stackoverflow.com/questions/2037316/php-session-destroyed-lost-after-header">that one here</a>, but my <code>$_SESSION</code> is not empty after <code>header()</code>, but partly deleted.</p>

    2. COFirst point is true, I've corrected it. It was already OK in my code. Using unset($_POST) or not does not hava any impact.

    3. COIs `session_start();` being called on your page `index.php?action=survey_part2` ? Also, in the end of your "controller" you have `redirect('index.php?aktion=umfrage_2&lang=de');` - shouldn't that be `header('Location: index.php?action=survey_part2');`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
