Well, that is what I think that I need. Please let me explain what I am trying to do
and tell me how to do it or a better way of doing it.
I have an application where a Screen (web page) may contain several Forms. The Forms
will want to access properties, etc, from their Screen. So what I want is to do
something like:
class Screen {
private $JavascriptVars = array();
function AddJsVar($name, $val) {
$this->JavascriptVars[$name] = $val;
}
}
class Form extends Screen {
public $screen; // Could set to a class Screen
function DefineForm($fName)
.....
}
$s = new Screen(....);
$s->AddJsVar('Date', '15 Oct 2011');
$f1 = new Form($s);
$f1->DefineForm('search');
$f1->AddJsVar('CompanyName', 'IBM');
$f2 = new Form($s);
$f2->DefineForm('login');
$f2->AddJsVar('Error', 'Login failed');
The trouble is that $f1->AddJsVar() will fail, class extention seems not designed to work like that.
I could make it work by either:
1) $f1->screen->AddJsVar() --- but I would rather avoid the extra '->screen'.
2) Use of a __call() in class Form -- but that makes things slower.
Any help gratefully received.
I think that to do what I want PHP would need a syntax like:
$f2 = new $s Form();
or
$f2 = $s->new Form();
