Help! Session variable changes to constant value!?!

sledgeweb

Hello-

I'm using session variables to store data in a form submission process. Everything works fine, except one of my variables keeps changing its value to a constant.

On PAGE2.PHP I have this:

session_register('titleId');
$SESSION['titleId'] = $POST['title'];
//print_r($_SESSION);
header("Location: PAGE3.php");

And on PAGE3.PHP, I have this:
session_start();
print_r($_SESSION);

The value is pulled from a $_POST array value, which is input via a drop down select form. The values are integers.

If I uncomment the print_r on PAGE2, everything is fine. I will have something like:

Array ( [titleId] => 4 )

Now, there isn't anything between the HEADER command on PAGE 2, and the print_r on PAGE 3, yet, the print_r on page three always results in:

Array ( [titleId] => 15 )

The variable is ALWAYS set to 15. Yet, I haven't done ANYTHING between what you see on PAGE2.PHP and PAGE3.PHP. I register the variable, set the variable, then go to page3 and print that variable out right after the session_start(), and it is changed to 15 EVERY TIME!! None of my other variables do this, just this particular one! Argh! Does this make any sense?

Please help!

Well, this is strange but I seem to have found the problem.

When I set the drop list, I use two temp variables:

$title and $titleId.

I use them to store the values of the current row in the query result, and then as i loop through, I print out something like

<option value=\"$titleId\">$title

When the user hits SUBMIT, it reloads the current page, and there is an IF statement at the top that checks to see if the form was submitted. If so, it does some error checking, and if everything is OK, it creates the session variables.

Now, someone explain this to me. If I create a session variable with the name "title", it will store the last value that $title held. And same with "titleId". The last values were

$titleId = 15
and
$title = "Wardrobe"

So, if I did this:

$SESSION['title'] = $POST['title']

instead of the session variables being set to the VALUE of the POST variable value, it would be set to wardrobe. And, if I used "titleId" as my variable, which I did, it would be set to 15.

Isn't that strange? Because, at the time the variables are being set, I've reloaded the page and I haven't even gotten back down where $title and $titleId are used (I redirect with the header line).
