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.

Parameters

none

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 + '<br>';
	/iterate;
/if;
