php sessions wont save form data
<p>Here's what I have so far. The problem is when I hit submit it takes me to the next page, but the session does not store the first name. If I remove the action, so it's action="" then the session saves the first name. Why does this happen and how do I fix it?</p>

<pre><code>...html stuff...

&lt;?php
session_start();
if(isset($_POST['submit'])){ $_SESSION['firstName'] = $_POST['firstName']; }
?&gt;

&lt;form method="POST" action="nextPage.php"&gt;
&lt;input name="firstName" type="text" size="70"/&gt;
...
&lt;input type="submit" name="submit" value="Continue"/&gt;
&lt;/form&gt;
</code></pre>
