hi all.

im trying to do the following :
a simple login page, asking the user for user/pass . verify that user exist in db and then, write the username to a session varm and then .
redirect him/her to another page that acts a small business online store .

what happens now, is that the user can purchase an item using paypal procedure, that redirects to a quick paypal secure check out page (payment page).

when payment is complete, i get a notification to a listener script on my server, that captures the payment status (and some other stuff....) and then runs another procedure that write all the relevant details to my db .

now, what im trying to do, is use the session var 'username' i saved in the 1st stage, and add it to the data i'm writing to the db .
except, when i run that cmd in the script, the session var holds no value .

i guess im not that educated on sessions. can anybody here plese give me a clue ?

you must have to use session_start function in the beginning of every page. and indexes are case sensitive

In php you start a session using:

PHP

SESSION_START();

To store a variable you use:

PHP

$_SESSION['var'] = "your value here";

To read from that variable in another page or even the same page use the same command minus the equals sign forward.
Then finally to terminate the session use:

PHP

SESSION_DESTROY();

Make sure not to terminate the session until your done reading the data because when you terminate the session it wipes the values.
