activate promo on viewinvoice.php

[Waqas Saeed]

Hey Guys. Loved this community.

What if I am looking for a script idea + hooks + API that can help to activate the promo code based on the specific gateway or if I am selecting some Gateway between 2 option. 

For instance; if incase am offering customers to pay with Paypal. and they get immediately 20% in total invoice. (specified by promo code) 

I prefer if I can get an idea with some sample code.. API

@sentq

 use this ActionHook:InvoiceGatewayChange to check the current gateway selected by user, then apply/remove your discount to his invoice using API:UpdateInvoice along with DB query, it might be tricky but it could be done.

I read your feedback in different topic/post about it,

Could you help me with some  API that can activate specific promo code on Action Hook : InvoiceGatewayChange and Update the invoice??

so the reverse of a Gateway Fees addon module, because what you want to do is effectively negative gateway fees... MG's Payment Gateway Charges addon can give discounts based on the chosen gateway, so that might be a solution ready to go.

adding promo codes into the equation would be an unnecessary complicating step in my eyes.

good luck expecting someone to write that for you (even in a generic way).... I think those days are over in this place - certainly on the scale in which it once occurred.

if you fancy a challenge, then there is a Gateway Fees addon module on GitHub - looks like the SQL queries will need to be updated, but the rest of the code looks fine to me... if that can handle negative fees, then it could be a starting point.

@Brains You're good always. let me find out if that can be done via the GitHub module.

I'm able to find out some details about that. and also installed that too. What about the reverse fee. Should I make necessary code to amend the code to work as gateway_reverse module ?

I wouldn't bother renaming it - though you might need to adjust the code as it might prevent negative fees from being used (re the code the checks if the values are less than zero).
