Calculated Pricing

Hi jschulbe,

Unfortunately, there is no pretty way to handle this, but a good way to get started is this walk through:

http://www.gravityhelp.com/documentation/page/Gravity_Forms_Pricing:_Adding_Tax

This will demonstrate how you can modify the order total both on the front end and the back-end. With a little more effort, you could use this same method to add on whatever additional fees you need to based on the width and height of the product.

On the front end, you'd want to retrieve the values of the height and width field via jquery.

[js]
var width = jQuery('#input_1_2").val();

You can then do your calculation and add the amount to the form total.

On the back-end you will need to to retrieve the width and height values from the $entry object which is passed from the gform_product_info hook (refer to the Tax example above). Again, you can do your calculations to get the amount to add. On this step though you can add it to the product total rather than just the form total.

I hope this makes sense. It is a fairly involved process.

Our new GF v1.6.4 Beta 1 was released today with calculations - see if that works for what you are trying to do:
