Description
This tag, based on code posted by Adam Randall here, returns a pair array containing the variables within the given session. The tag must be loaded via LassoStartup, and will only return results when the value of [session_result] is "load." Otherwise returns "Undefined." Currently works with "Local Default" (SQLite) or "External" (MySQL) sessions. "In-Memory" sessions are not supported.
Sample Usage
// display all the vars in the session with their values
if(session_vars('mySession') != 'Undefined');
iterate(session_vars('mySession'), local('i'));
#i->first + ': ' + #i->second + '
';
/iterate;
/if;
