PHP $_SESSION problem
<p>For some reason my post id session is not carrying over to my grading script page. I grab the post_id from the posts url in my posts page and turn it into a <code>$_SESSION</code> to carry it to my grading script page.  My <code>$_SESSION</code> that holds the logged in users id <code>$_SESSION['user_id']</code> if logged in carries over to the grading script but not the post <code>$_SESSION</code>. How can I have my posts id carry over to my grading script page?</p>

<p>I have <code>session_start();</code> at the top of both of my pages.</p>

<pre><code>$_SESSION['post_id'] = $_GET['pid'];
</code></pre>
