Hi There,
I’ve created a radio button (lines 812-818) where you choose either yes or no.
I’ve added some additional code at lines 658-660, and also lines 757-770.
Basically what I’m looking to achieve is at line 129 I’ve added the following code:
‘paymentaction’ => ‘authorization’
This code allow all PayPal payments to come through as authorisations, as opposed to completed payments, which are captured straight away.
I’ve added the radio button, so that you can choice either yes or no, yes for line 129 to apply, where payments come through as authorisations, an no, where line 129 codes wouldn’t be used.
Not sure how I can implement this, by saving the either yes or no selection and then getting the result of the selection to work.
Any help would be really appreciated. Kind Regards, Andy (below is the full code):
