FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

PayPal module for Kohana 3.3
Installation
- Clone into the 'modules' directory of your Kohana installation or run
composer require guss77/kohana-paypal - Add a reference to load the module in your 'bootstrap.php' file
- Copy 'config/paypal.php' to your application's 'config' directory and edit according to your requirements:
- Replace the client Id and secret with your real PayPal client ID and secret
- You may also want to change the default currency
- Copy 'classes/PayPal.php' to your application's 'classes' directory and implement the abstract methods:
PayPal::approved()should handle recording the data for the completed transaction and return a URL to direct the user to - for example, a "thank you for buying" page. See below for details.PayPal::cancelled()should handle recording that the transaction was cancelled and return a URL to direct the user to - for example, a "sorry that you cancelled your purchase" page. See below for details.
Usage
To create a transaction, call PayPal::payment($amount) where $amount is the transaction amount.
Please note that, while not required, you should pass $amount as a string, otherwise if the amount is not an integer
(i.e. it has a fractional part) then it may be subject to IEEE 754 floating point rounding. To prevent that, the module
truncates numeric floating point amounts to 2 decimal points, but that operation may still be subject to rounding.
PayPal::payment() will redirect the user to approve the payment through PayPal web interface. When the user completes the approval, the method PayPal::approved() in the application's implementation will be called. The approved() method receives the transaction completion details and can do any processing it needs, and then return a URL to which the user will be redirected.
If the user cancelled the transaction, the PayPal module will call the method PayPal::cancelled in the application's implementation, which will also need to return a URL to redirect the user.
An Example flow:
- User clicks on the "buy" button on the page for product "A123".
- Application calls PayPal::payment($priceForProduct, [ 'ProductId' => "A123" ]);
- User gets redirected to PayPal and approved the payment.
- User gets redirected back to the site where the PayPal module completes the transaction.
- PayPal module calls the Application's PayPal::approved([ 'ProductId' => "A123" ], "PAY-ABCD1234EDFGH5678", (object)[ "email" => "[email protected]", "first_name" => "first", "last_name" => "Last", "payer_id" => "ABCD1234EFGH", "shipping_address" => (object)[ ... ] ]);
- approved() registers the transaction completion in the database and orders a delivery for the user
- approved() returns the URL to the "thanks for purchasing" page
- PayPal module redirects the user to the "thanks" page.
