Please help: session variable

["ST Wong (ITSC)" <ST@xxxxxxxxxxxxxxxx>]

Hi all,

 

I'm newbie to PHP and working on migration of some PHP codes written by others to new server.

 

The main PHP script has some session variables defined. However, after displaying a template:

 

$smarty->display('show_form.tpl');

 

all session variables are gone:

- session_status shows session is active

- session_id shows the correct session id

- /var/lib/php/session/sess_xxx file becomes empty after submitting the form in the template.

 

 

The template is a simply form looks like following:

 

<form name=myForm _onSubmit_="return validatePwd()" method="POST" action="" ">

 

 

session_start() is called at the very beginning of the main PHP script.

 

Besides sessions variables, all variable defined are also lost, eg.

 

$b1 = $_SESSION['logined'];

 

We're using PHP 7.2.24 bundled with CentOS8 and using Smarty 2.6.30, though seems not Smarty related issue.

 

Would anyone please help?

 

Thanks a lot.
