well I found a way. It's a bit of a hack but FYI heres how it works:
function Form() {
// a slight hack which allows us to overload
// constructors by the number of args
$name = "Form".func_num_args();
$arg_list = func_get_args();
$num_args = func_num_args();
switch($num_args) {
case 0:
$this->$name();
break;
case 6:
$this->$name( $arg_list[0],
$arg_list[1],
$arg_list[2],
$arg_list[3],
$arg_list[4],
$arg_list[5]);
break;
default:
echo "Wrong number of args for constructor!";
}
}
// pseudo-constructor for 0 args
function Form0() {
$this->formName = "myForm";
$this->formAction = $_SERVER['PHP_SELF'];
$this->formMethod = "POST";
$this->formVersion = "xhtml";
$this->formLanguage = "en_gb";
$this->formStyle = "/styles/form.css";
$this->formElementCount = 0;
}
// pseudo-constructor for 6 args
function Form6($formName,
$formAction,
$formMethod,
$formVersion,
$formLanguage,
$formStyle) {
$this->formName = $formName;
$this->formAction = $formAction;
$this->formMethod = $formMethod;
$this->formVersion = $formVersion;
$this->formLanguage = $formLanguage;
$this->formStyle = $formStyle;
$this->formElementCount = 0; // don't allow user to
set this
}
