Allow Shift + Enter to Submit Form

Question

I have a simple form whose action posts to a basic PHP script. The problem I have discovered is that if someone is typing fast and accidently has the Shift key down when they hit " Enter " a whole slew of PHP error messages pops up. How can I allow Shift + Enter to work just like " Enter " or at least prevent all the error messages from popping up?

Currently I do not have any Javascript in use with this form. The submit button is simply <button class="submit button" type="submit">Update</button>

Assuming you are using jQuery...

$('input').keyup(function (event) {
   if (event.keyCode == 13 && event.shiftKey) {
       event.stopPropagation();
  }
 });

Alternate to using directly with Javascript (might need to test it out)...

document.getElementsByTagName("input").onkeyup=function(event){
    if (event.keyCode == 13 && event.shiftKey)
    {
        event.stopPropagation();
    }
}
