SessionGet

NAME

SessionGet

FUNCTION

The PHP function Session get returns a session variable. The second parameter is a Standard Default Value and will be returned if the Session variable Var_Name does not exist.

The framework itself tracks only 2 session variables. These are UID, which is user_id, and PWD, which is user password. An application must be careful not to overwrite those values, as the framework will make no provision to prevent such an accident.

INPUTS

string $key key for the value to receive from $_SESSION mixed $default default value for key

RETURN VALUE mixed value associated with $key

SOURCE

function SessionGet($key,$default="",$sfx='app') {
   $xkey=$GLOBALS["AG"]["application"]."_".$sfx."_".$key;
    if (isset($_SESSION[$xkey])) {
        return $_SESSION[$xkey];
    }
    else return $default;
}
