I use check boxes to select several text areas. I will have a send button for inputs of selected check boxes so disabled ones wont be sent to server side.
But I cannot really figure out how to not send deselected data by coding PHP. I am not really sure, probably, I should have looked for a JS code.
You don't have to do anything else if your text areas are already disabled:
Values of disabled controls are not submitted with a form.
you can use :<INPUT disabled name="fred" value="stone"> for more Details go to Link
