Possible to restrict coupon use to payment type?

[Faizal1]

Hi there,

Is it possible to restrict a coupon code so it can only be used for a certain payment type? E.g Can only be used if paying via PayPal?

Thanks

Hi @Faizal1

Thanks for your post, out of the box, no, it is not possible to restrict a coupon to. a certain payment method I'm afraid

Ok, thank you Chris. Will have to rethink the coupons then i guess.

using an action hook, you could prevent checkout if your condition(s) weren't met, e.g if specific promocode and paypal used, stop checkout process and display visual warning that they can't use that combination and ask them to either change gateway choice or remove promocode from cart.

Oh wow thanks @brian!. That sounds promising. I'm not to familiar with writing hooks but i'll start researching now.

ShoppingCartValidateCheckout is the one i'm thinking of - at it's most basic, it's going to take less than a handful lines of PHP code. 🙂

Thanks again Brian. I found another post with the 'Check For Promo Code Hook' code posted by you and that part looks great. Now i'm trying to figure out how to adapt that but I have no idea about php code really but only one way to learn so will see what i can come up with.

at the most basic, the hook below would work - it should just need to change the promocode from "basic" to your promotion code name; and the paymentmethod to your paypal gateway name (there are a few PP gateways now, so you will need to choose the name of yours).

<?php

add_hook('ShoppingCartValidateCheckout', 1, function ($vars) {
	$promocode = $vars['promocode'];
	$paymentmethod = $vars['paymentmethod'];
	if ($promocode == "basic" && $paymentmethod == "paypalcheckout") {
		return 'You cannot use Paypal with this promotion code - either change your payment method or <a href="cart.php?a=removepromo">remove</a> the code';
	}
});

ideally, that return should be a language string if your site has multiple languages - but just get it working for now and tweak it after that.

I think for your situation you won't even need to both checking that the promocode exists or is valid, you're just blocking certain promocodes being used with certain gateways regardless of whether they're valid or not.

you can call it whatever you want to - but the filename must end in .php and contain no spaces...

personally, I wouldn't call it either of the above, i'd give it a memorable name such as promocode_paypal.php

it should be uploaded to the /includes/hooks folder.

Hello,

Is there any way to give automatique discount if a user choose Paypal to pay in the final step? 

Thank you

not from settings.... there are gateway fees addons available in Marketplace and if any of them allow negative fees/percentages, then that should work for your situation.

you could use hooks, but depending on the paypal gateway, you might not know whether they've used PP until after checkout.
