I have a php form (call it Home.php) and on submit (method Post), I have information being validated in a separate php script(call it Validate.php).
Once validated, session variables are being initialized/set in Validate.php. Once these variables are set, I'm redirecting back to the home.php page using header('Location: home.php') in the validate page.
All this works perfectly, and I can access the session variable and display it on the home.php page, but as soon as I hit refresh, the variable values are gone. Even if I don't refresh home.php, if I go to another page on the server and try to access the session variables, they are blank/not set.
Few points: I have Session_Start() in all my pages and at the very beginning. The session save path config value is /tmp and that doesn't seem to be the issue, because, I can set and retrieve the session values on the first attempt like I mentioned above.
I searched Stackoverflow and google, but couldn't find anything. You are my last resort. Hope someone can help me here.
Thanks in advance.
Home.php::
<?php session_start();
echo '<!DOCTYPE html>';

And some HTML CODE HERE FOR DISPLAYING THE PAGE....

Ok...Here's what I found in my code, once I posted it here. There is a session destroy in the code in Home.php and that's what has caused all these Shenanigans.
I removed the Session_Destroy() and the Onclick event, and it all works perfectly, like its designed to.
Thanks Mike and Dan for your time.
