How to get product quantity or total price from WooCommerce product page
I have done button on product page. When user clicks it, pop up will open where user can see product price with installment.
But it calculate price of one product. I want to do so that it will calculate installment price dependent of quantity of product that user selected. (‘Product Quantity’ x ‘Product Price’ = ‘Product Total Price’)
For example: There is White Shirt on the site. It coasts 40$. User want buy 4 from this Shirt. And He want to see installment rate of it.
The pop up must get quantity of the product.
So How can I get quantity of the product or total product price from product page?
Please Help! Thank you!
