It's always the stupidest oversights that make the most problems. Right there on line 2... session_start; should be session_start(); Printing the _SESSION and _POST arrays before and after I was reassigning the post variables to session variables helped me see that $_SESSION didn't exist before I assigned variables. Therefore, the session wasn't being created. Thanks again, gang.

I'm pulling in the primary key for each question when I pull it from the db. So, each field name & ID ends with the primary key (assuring a unique ID). Great simple debug step I hadn't looked at yet. I haven't examined the $_POST array at that stage. Good call. I saw that a while after I posted the code. Was working on those switches when I realized my variable values were dying and got distracted. I'll try the recommendations that have stacked up in this thread and post back if I identify the problem(s). Thanks, all.

Many thanks for the reply. That seems sorta like what's going on, but I don't think it should actually be happening (that's the jist of my problem). I'm trying to understand how that would happen or what's causing it. Clarification: I think I'm dropping each POST value into it's own session variable. (see snip below) My understanding is that unless another value is assigned to that variable during the session, it should still exist. Right? Each post operation seems to wipe out any session variables set on previous posts. I'm just not getting why. :'( foreach($_POST as $key => $data) { $_SESSION[$key] = $data; }

Something more like this should get the image you want to display. Your loop doesn't know about the bit after it. (if ($green_dot = 'read')...) You could use a simliar conditional to drop bold tags if that's how you'd like to do it as well. Using CSS to hit the whole row might be a little tidier, though. echo "<table border='1'> <tr width='200'> <th>View</th> // code to display table removed </tr>"; while ($row = mysql_fetch_array($result)) { echo "<tr>"; $id = $row['ID']; echo "<td><a href='/view_message.php/?view_message=$id'>View</a></td>"; if ($row['message_status'] == 'read') { $img ='green.jpg'; } else { $img ='red.jpg'; } echo '<td><img src="assets/' . $img . '"/></td>'; echo "<td>" .$bold . $message_status = $row['message_status'] . "</td>"; echo "<td>" .$bold. $row['date_sent'] . "</td>"; echo "<td>" .$bold. $row['contact_name'] . "</td>"; echo "<td>" .$bold. $row['subject'] . "</td>"; echo "</tr>"; }

Your code would be helpful for sure. There are slew of ways you can approach this, but it's hard to make a useful recommendation without knowing how you're doing what you're already doing.

It's been a while since I've needed to whip anything substantial up from scratch, so my scripting is a little (lot) fast and loose (weird/inefficient) here. I'm trying to mock up a script that's essentially a quiz/survey. There are a handful of topics, each with a few screens of yes/no questions. At the end, it returns a list of recommendations based on the answers gathered. The script is posting back to itself. Using print_r ($_SESSION), it seems like all of the post values for the first screen of questions are being assigned to the session array as expected. When the second screen of questions is answered, their values are assigned as well, but the values for the first set go away completely. This continues through subsequent screens, with the values from the previous screen present and all others before missing. I'd really appreciate a look at my code to see if you tell me the cause or error(s).
