about php...do session variables transmit themselves from a php page to another?

[neca]

cause i know if i use a form when i push submit all the variables entered in the textbox go to the action page...so,without using a form,is the same principle working?do they transmit from page to page?....cause i tried and seems it doesn't work..so do i have to work more or just drop the idea?

Yes they do go from page to page if you have session_start() at the top of every page.

ps - remember that sessions only work if you have cookies enabled, because they work using cookies a little.

initializesession.php
session_start()
$_SESSION['testvar'] = "test";


restievesession.php
session_start()
echo $_SESSION['testvar']


JUST TRY TO RUN 1ST FILE "initializesession.php" AND THEN "restievesession.php" YOU WILL GET THE OUTPUT,BUT IF U RUN THE 2ND FILE "restievesession.php" FIRST THEN U NEVER GET THE OUT,SO FIRST U INITIALIZE THE VARIABLE IN THE SESSION AND THEN U CAN RETRIEVE THAT VARIABLE ANY WHERE IN THE PROJECT BUT THE CONDITION WILL BE U MUST DEFINE session_start() FUNCTION
