[SOLVED] Dynamic Values in Function

[dfowler]

Hey guys, I'll get right down to it.  Here is the code:

function refreshPrice() {
  var selectedradio;
  for (i=0;i<document.getElementById('appform').elements.length;i++) {
    ele = document.getElementById('appform').elements[i];
    if (ele.type == 'radio' && ele.name == 'coverage' && ele.checked) {
      selectedradio = ele;
      break;
    }
  }
  price = (document.getElementById('equipment').checked ? 225 : 0) + (document.getElementById('technical').checked ? 0 : 0) + (document.getElementById('personal').checked ? 48 : 0) + pricekeys[selectedradio.value];
  document.getElementById('totalprice').innerHTML = '$'+price.toString();
}

 

I need the equipment(225), technical(0), and personal(48) to be modified depending on what their value is in a database.  Anybody know how to do this?

In your php file

price = (document.getElementById('equipment').checked ? <?PHP echo $EquipValue;?> : 0) + (document.getElementById('technical').checked ? <?PHP echo $TechValue;?> : 0) + (document.getElementById('personal').checked ? <?PHP echo $PersValue;?> : 0) + pricekeys[selectedradio.value];

 

given the $EquipValue, $TechValue and $PersValue is the value from your db.

will this work even if this is from an external javascript document?

You can include your "price" variable in your PHP page and then link to your External JavaScript or you can convert you JS file to a PHP file and set the header to be a JavaScript file; then link it like you would any other external JS file - except your script extension would no longer be "js"; it would be "php". It's up to you how you want to do it; the first way, I mentioned, is probably the easiest way.
