Transaction_Id And Receipt In Chapter 6

[olaoyesunday]

Dear Admin,

 I'm integrating a payment processor named Global pay by Zenith bank Nigeria on my site. The site is subscription site similar to Knowledge is power. My script is the same as registration.php in chapter 6 the only difference is where I change paypal code for global pay. I want to ask 2 questions :

1) How can I generate transaction_id on my site for payment processor from my code? I thought paypal generated it for us behind the scene but here they want my site to generate it for the payment processor.

 

2) How do I include receipt.php  for customer to print after completing the order on paypal without relying on the one paypal will send to the customer like we did in chapter 13?

If the payment processor wants you to generate it for them, you'll need to generate something random, unique, and secure. You could use a tool like this one to do that: https://github.com/ircmaxell/RandomLib

 

For the receipt, I thought I included an example of that in the book, or in the downloadable code as an extra.

Thanks very much.

After downloading the library from github, the instruction is not clear on how to make use of the library.  I tried using

RandomLIb/generator

generator->generateString(32, 'abcdf'). it was saying the class not found.

 

I tried using rand(1111222233334444, 5555666677778888). it works  but not given me the consistent 12 digits number? please, bail me out.

Sure thing. First, you include the library. Then you would do this:

$factory = new RandomLib\Factory;
$generator = $factory->getMediumStrengthGenerator();
string$bytes = $generator->generate(32)
