And it will still do that if you just submit the form and have the
loading page close itself. But life is simpler than that.

If your only need is to have a PHP script execute, you don't need the
IFrame or the new window. You only need them if you want some return
value from the PHP code.

No, change the method from post to get and the browser will
automatically add it to the URL. But, have the PHP code read the
submitted form data. Your checkbox and hidden field values will be
available to it.

The browser does it for you. Try it. The PHP page will have access to
the checked checkbox.

Nor any browser on a PC. The smallest window I recall being able to open
on a PC was 100x100 or so.

Fair enough.

Actually, it doesn't. You can do it in the same window without
disrupting it.

It does if the form is submitted.

If you are not getting a return value from the PHP code, you can simply
set the .src of an Image Object to the string you need.

<iframe name="myIFrame" style="width:0px;height:1px;"></iframe>

And submit your form....
