Dynamic Pricing

-- HikaShop version -- : 2.3.3

Hello,
i'm planning to use hikashop for selling email marketing service, i can do that via: Hikashop->Products->Characteristics
for example
0-500 subscriber $10
510-100 subscriber $15
etc..

now my question is, if in the middle of the month customer would like to upgrade to next level of plan.. i need to calculate the upgrade fee based on pro-rata plan.. i can do the calculation, but how can i set this pricing to their cart ?

Thanks

Hi,

Why not create "upgrade products" ?

Else you can create one "upgrade product" then create a plugin based on the function "onBeforeCartUpdate()" and in this function do a PHP check on the product added in the cart, make a request to get the orders of the currently logged in customer in order to knwo the current subscription.

Then edit dynamically the price of the added product to the correct value.

Here is the developer documentation for the plugins:

Thanks for the insight...
love hikashop
