    <p>You're losing the data sent to the server when you do the redirect.</p> <p>Basically, you've got 3 options:</p> <ul> <li>Store the data on the client using a cookie or similar (A lot of overhead for something simple)</li> <li>Store the data server-side in a session or similar (even more overhead)</li> <li>Pass the data through the URL you're redirecting to...</li> </ul> <p>So something like:</p> <pre><code>if (array_key_exists($_POST['dropdown-name'], $pages)) { header("Location: " . $pages[$_POST['dropdown-name']] . "?personsName=" urlencode($_POST['name'])); } else { //Blah } </code></pre> <p>Which seems to be the best answer for your simple example. If there's a LOT of data or it's more complex, consider using one of the other 2 option above</p> <p>NB: On the form you've called the variable <code>name</code>, on the pae receiving it, you've called it <code>personsName</code> - note the mapping from one to the other in the URL.</p> <p>Javascript solution (tested):</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;SO Demo&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;script type="text/javascript"&gt; function UpdateFormAction(){ var form = document.getElementById('MyForm'); var list = document.getElementById('PageList'); var desiredAction = list.options[list.selectedIndex].value form.action = desiredAction; document.getElementById('Target').innerHTML = 'Form action set to: ' + desiredAction; } &lt;/script&gt; &lt;form id="MyForm" action="letter.php" method="POST"&gt; Name: &lt;input type="text" name="name" /&gt;&lt;br /&gt; Page: &lt;select id="PageList" name="letter" onchange="UpdateFormAction();"&gt; &lt;option value="letter.php"&gt;Page 1&lt;/option&gt; &lt;option value="letter2.php"&gt;Page 2&lt;/option&gt; &lt;option value="letter3.php"&gt;Page 3&lt;/option&gt; &lt;/select&gt; &lt;input type="submit" value="Print" /&gt;&lt;br/&gt; &lt;span id="Target"&gt;Form action unmodified&lt;/span&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    1. COIn the actual form I'd be getting 10 pieces of information to populate the redirected page. Is that too much to use this method?

    2. COThere's a limit on how long URLs can be (1024 characters for IE6, at least 4096 for all later/more modern browsers if I remember correctly) so it will depend on what the data is. simple input fields should be fine but large textareas could be a problem.

    3. COoh and of course, you could use some simple javascript so that when the drop-down is changed, the `action` of the form changes to the appropriate page - so then there's no PHP step in the middle and you submit directly to the desired page.

Guidance
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.

SQuiL has stopped working due to an internal error.

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