session issues: not showing

[RobLamb]

Hi Everyone

I am having a problem with some session variables. Basically I am setting them based on fields in a form, then I need to use them for an update query in another page. If I view all the variables set, I can see them, but they are not coming through in my code where I need them.

 

Print out of page where I am checking them. (The two i need are frPrefixTwo and frNoTwo) Please help urgent;y on this guys!! I am really stuck.

ses1:

ses2:

SELECT stockId FROM tblstock WHERE stockEnginePrefix = '' AND stockFrameNo = ''

$col2_rsStockId = $_SESSION['frNoTwo'];

echo "ses1: ".$_SESSION['frPrefixTwo']."<br/>";

echo "ses2: ".$col2_rsStockId."<br/>";

mysql_select_db($database_conYamaha, $conYamaha);

$query_rsStockId = sprintf("SELECT stockId FROM tblstock WHERE stockEnginePrefix = '".$colname_rsStockId."' AND stockFrameNo = '".$col2_rsStockId."'");

echo $query_rsStockId;

$rsStockId = mysql_query($query_rsStockId, $conYamaha) or die(mysql_error());

$row_rsStockId = mysql_fetch_assoc($rsStockId);

$totalRows_rsStockId = mysql_num_rows($rsStockId);

 

session_start();

$_SESSION['stockId'] = $row_rsStockId['stockId'];

 

session_start();

Print_r ($_SESSION);

your session_start() should be the first thing you initialize in the script, that will start the session and give you access to the session vars

Hi Ravi

I do this on the page before.

session_start();

set all my session variables

 

run some scripting (use the 2 I need to run one set of script commands here)

 

redirerct to next page

 

variables then come out empty

[bbaker]

session_start(); needs to be on EVERY pages where you are setting or retrieving session variables

Thanks bbaker! A lot of time that wasted for me!!!!!! THANKS!
