session variable

[Oleksandr]

Good day.
Tell me please.
in which part of the page would it be correct to specify the session variable $_SESSION['username'] = $_username;
To use $_username in queries as a value.

PHP session variables should be set at the start of the page.
Note that this is not specific to WWB. This is standard PHP functionality.

Thank you very much for your reply.
I know this does not apply to WWB.
So thank you again.
