<input type="text" id="REI1" maxlength="4" onfocusout="TextBoxAway(this.id);" name="REI1">

I have about 8 of these and I have this function to make it uppercase. It will also get rid of texbox formating on focus lost.

function TextBoxAway(id) {
  if (document.getElementById(id) == null){
    return
  }
  else {
    var x = document.getElementById(id);
    x.value = x.value.toUpperCase();
  }
}

I need to try to get all 8 of these input boxes to update in a sql database with php every time they are changed (Focus Lost). I also need them to reshow up when the user is logged in so it will be saved with a user id. Any Help would be appreciated.
