No. It's your browser that reads the form and sends a request to the
server for your specified action, calculator_sub.php. Php does not run
on the client. Php only runs on the server.

And the browser is not posting the textarea value because the the
textarea is disabled.
(You could add -
document.forms["region"].elements['fgData'].disabled=false - wherever
you see fit, but this is strictly a JavaScript question, not Php.)
