How to calculate price by non-predefined attribute value?

Hello,
I am installing NopCommerce for my company - a latex maxtress company - and facing a problem on product price. A maxtress product has its size and the size is not predefined. Customers can buy any size of maxtress which fit their need. The problem is product price is not predefined too. It is calculated based on product's size. So, please instruct me which is the best way to do that?

Many thanks

As you told that product price and size are not predefined so may be you need to change the source code.But if you want to apply different price for different size of a product then you can handle this situation by product attributes.

you need to customized for it.

AS you don't have predefined price and size i think you can not use the product attribute values as well b'coz on that also you need to add the size and its price adjustment values.

so i think you need to create some new mapping table on which admin need to add size and its price adjustment value or may be size range and its price adjustment value to update the prices.

Thank you for your opinions. I agree with you that I cannot use attributes. After some investigation and discussion with my team, I have decided to modify the source code to get price each time user enters a size.

Hello

About the issue of calculating price from none predefined attributes, our development team has made the “Calculating Price from Attributes” plugin which would allow the store owner to dynamically calculate the price of a product by using basic mathematical operators and formula.

With this plugin, the store owner would use the attributes as variables in their formula. After that, at the time of adding the specific product to the cart, the customer would enter the values for the defined attributes and the price of the said product would be calculated using the defined formula by the store owner and variable’s values entered by the customer.

You can check the full description and a demo version of this plugin here.
