Class documentation can be found here https://flutterwave.github.io/Flutterwave-Rave-PHP-SDK/packages/Default.html
Use this library to integrate your PHP app to Rave.
Edit the paymentForm.php and processPayment.php files to suit your purpose. Both files are well documented.
Simply redirect to the paymentForm.php file on your browser to process a payment.
The vendor folder is committed into the project to allow easy installation for those who do not have composer installed. It is recommended to update the project dependencies using;
$ composer installIn this implementation, we are expecting a form encoded POST request to this script. The request will contain the following parameters.
- payment_method
Can be card, account, both - description
Your transaction description - logo
Your logo url - title
Your transaction title - country
Your transaction country - currency
Your transaction currency - email
Your customer's email - firstname
Your customer's firstname - lastname
Your customer's lastname - phonenumber
Your customer's phonenumber - pay_button_text
The payment button text you prefer - ref
Your transaction reference. It must be unique per transaction. By default, the Rave class generates a unique transaction reference for each transaction. Pass this parameter only if you uncommented the related section in the script below.
