[RESOLVED] sessions with pagination and trans_id off

[kilbey1]

After doing a search for sessions on the forums, I'm still no clearer on resolving my issue.

I have a form on page1.php that posts to page2.php.
page2.php includes pagination by way of a class.

I set up debugging output for post, get, session, request, and the following:

if(isset($_SESSION['temp'])) {
		$_SESSION['temp'] = TRUE;
		$_SESSION['PropertyType'] = $_POST['PropertyType'];
		$PropertyType = $_SESSION['PropertyType'];
	} else {
		$PropertyType = $_SESSION['PropertyType'];		
	}
	print_r($_SESSION);
	echo $PropertyType;		

When I post to page2.php, I get these results:

POST: Array ( [PropertyType] => res [bedrooms] => No Minimum [bathrooms] => No Minimum [priceMin] => 0 [priceMax] => 200000 [acreageSize] => [schoolDistrict] => [zipcode] => [submit] => Search by Detailed Criteria ) 
GET: Array ( ) 
SESSION: Array ( [temp] => ) 
REQUEST: Array ( [PropertyType] => res [bedrooms] => No Minimum [bathrooms] => No Minimum [priceMin] => 0 [priceMax] => 200000 [acreageSize] => [schoolDistrict] => [zipcode] => [submit] => Search by Detailed Criteria [cprelogin] => no [cpsession] => TKv6jbJ1VVPGhpQVLFRHgzVXVhGyNTIa8EHqhOK4lGki9PF9fxQoPc6OJMzf0xxm [PHPSESSID] => 00dc158e5f4c9eb358a38f6da5ef8799 [webmailrelogin] => yes [webmailsession] => closed ) 
Array ( [temp] => 1 [PropertyType] => res ) res

When I click on any pagination within page2.php, I get this:

POST: Array ( ) 
GET: Array ( [page] => 2 ) 
SESSION: Array ( [temp] => ) 
REQUEST: Array ( [page] => 2 [cprelogin] => no [cpsession] => TKv6jbJ1VVPGhpQVLFRHgzVXVhGyNTIa8EHqhOK4lGki9PF9fxQoPc6OJMzf0xxm [PHPSESSID] => 00dc158e5f4c9eb358a38f6da5ef8799 [webmailrelogin] => yes [webmailsession] => closed )

Where am I going wrong? I've tried all sorts of session tricks and nothing's worked yet.

Environment:
PHP 5.1.4
session.use_trans_sid = 0
session.name PHPSESSID
session.use_cookies On
session.use_only_cookies On

Since you didn't post all of the necessary code, I have to ask the obvious question, did you put session_start() on page2.php?

[kilbey1]

Hi, sorry for the slow response, started a new job this week.

Yes, session_start() is at the top of page2.php. It then posts back to itself when clicking a page link, hopefully re-using the function.

I've attached the 2 code pieces so you can see what's happening. Thanks!

P.S. I realize this is not 'clean' code yet - I'm going to return to it later to revise for better security. I'm also planning to rework some of this into a class, but for now...

Perhaps you are resetting the array in the middle of a process?
Look for $_SESSION = array();

If that doesn't help.. my recommendation is to put beacons in your scripts and see at which point the session variables are messed up..

Distribute lines like these inside your code
echo "<br>-------------1 " . (isset($SESSION['PropertyType']) ? "is set" : "NOT SET");
..code..
echo "<br>-------------2 " . (isset($SESSION['PropertyType']) ? "is set" : "NOT SET");
..code..
echo "<br>-------------3 " . (isset($_SESSION['PropertyType']) ? "is set" : "NOT SET");

Thanks so much for this. I ended up with this, and think this will serve. (cleaning input remains yet)

I ran across a small problem, in that since it posts to one page and the session must be maintained throughout that page on pagination, I wasn't sure where to place the session_unset(). I couldn't get the darn form to reset the session when inputting new criteria and posting again. As it's posting from just one particular form at a time, I figure this is the way to go.

if(isset($_POST['submit']['Search by Detailed Criteria'])) {

	session_unset();
	$_SESSION['PropertyType'] = $_POST['PropertyType'];
	$_SESSION['bathrooms'] = $_POST['bathrooms'];
	$_SESSION['bedrooms'] = $_POST['bedrooms'];
	$_SESSION['priceMin'] = $_POST['priceMin'];
	$_SESSION['priceMax'] = $_POST['priceMax'];
	$_SESSION['neighborhoods'] = $_POST['neighborhoods'];
	$_SESSION['firstfloorbedroom'] = $_POST['firstfloorbedroom'];
	$_SESSION['acreageSize'] = $_POST['acreageSize'];
	$_SESSION['schoolDistrict'] = $_POST['schoolDistrict'];		
	$_SESSION['zipcode'] = $_POST['zipcode'];		
	$_SESSION['fireplace'] = $_POST['fireplace'];		
	$_SESSION['pool'] = $_POST['pool'];


	//validation code follows here....


} else {

	$PropertyType = $_SESSION['PropertyType'];
	$bathrooms = $_SESSION['bathrooms'];
	$bedrooms = $_SESSION['bedrooms'];
	$priceMin = $_SESSION['priceMin'];
	$priceMax = $_SESSION['priceMax'];
	$neighborhoods = $_SESSION['neighborhoods'];
	$firstfloorbedroom = $_SESSION['firstfloorbedroom'];
	$acreageSize = $_SESSION['acreageSize'];
	$schoolDistrict = $_SESSION['schoolDistrict'];
	$zipcode = $_SESSION['zipcode'];
	$fireplace = $_SESSION['fireplace'];
	$pool = $_SESSION['pool'];

}

//echo "SESSION: ";
//print_r($_SESSION);

That is the way I work too.. but do not use session_unset() with $_SESSION .. they are not compatible.

To reset the session use $_SESSION = array(); instead of session_unset()

[kilbey1]

Ah yes, predefined globals. Thanks for your help!
