TOPIC: Order form with different prices for different qty

Order form with different prices for different qty 7 years 2 months ago #37948

I've got an order form with items in various price breaks. How can I apply the different prices to the calculation and form total?

Example :
10-50 items 9.99
51-100 items 8.99
101-151 items 7.99

Thanks in advance.

Greetings Wintercorn!

To accomplish this, you need some Javascript in your form. I built a quick test and this works with the latest RSFormPro version.

First, you need a place in your form for both the entered quantity and the price. I tried to use a Free Text field but it didn't work, so I used a normal Text field. I labeled it "Price Each", then in the Attributes->Additional Attributes I added:
id="Price" disabled

The "disabled" prevents the user from changing it themselves, but the script can still change it.

The user-editable Quantity field was given:
id="QTY"

Then, in the Form Properties, under CSS/Javascript, I wrote this little script:
<script type="text/javascript">
function calculatePrice(){
    var q = document.getElementById('QTY').value;
    var price = 9.99;
    if(q>50 && q<=100) {
        price = 8.99;
    }
    if(q>100 && q<=150) {
        price = 7.99;
    }
    if(q>150) {
        price = 6.99;
    }
    document.getElementById('Price').value=price;
}
</script>

It isn't the simplest thing, but it isn't too complex, either.

I hope the helps.

I forgot a step! Sorry:

On the Attributes on the Quantity field, add:
onChange="calculatePrice()"

otherwise the function never gets called. Sorry I missed that originally.

Thanks for the reply. I can't quite get this to work :-( Are you able to export the form so I can test and modify?

Update : It's not changing the price at all. It only shows the base price regardless of quantity.

More update : function calculatePrice is not defined.
Last Edit: 7 years 2 months ago by wintercorn. Reason: more updaterer

It sounds like you may have put the Javascript part into the CSS (top) field of the CSS/JavaScript page, instead of in to the JavaScript (bottom) part?

No, they are in the correct places. Do you have an export of your working form?

Thanks
