Paypal Web Payments Pro Package
This package was written to interact with any PHP application, but I'll demo
using CakePHP 3.x to show how to connect to it., (*1)
Composer Settings
First we'll want to add the library in via the composer.json file.
"cpierce/paypal-wpp": "3.*" will need to be added into your require as follows:, (*2)
File: composer.json, (*3)
{
"name": "cakephp/app",
"description": "CakePHP skeleton app",
"homepage": "http://cakephp.org",
"type": "project",
"license": "MIT",
"require": {
"php": ">=5.5.9",
"cakephp/cakephp": "~3.3",
"mobiledetect/mobiledetectlib": "2.*",
"cakephp/migrations": "~1.0",
"cakephp/plugin-installer": "*",
"cpierce/paypal-wpp": "3.*"
},
"require-dev": {
"psy/psysh": "@stable",
"cakephp/debug_kit": "~3.2",
"cakephp/bake": "~1.1"
},
"suggest": {
"phpunit/phpunit": "Allows automated tests to be run without system-wide install.",
"cakephp/cakephp-codesniffer": "Allows to check the code against the coding standards used in CakePHP."
},
"autoload": {
"psr-4": {
"App\\": "src"
}
},
"autoload-dev": {
"psr-4": {
"App\\Test\\": "tests",
"Cake\\Test\\": "./vendor/cakephp/cakephp/tests"
}
},
"scripts": {
"post-install-cmd": "App\\Console\\Installer::postInstall",
"post-autoload-dump": "Cake\\Composer\\Installer\\PluginInstaller::postAutoloadDump"
},
"minimum-stability": "stable",
"prefer-stable": true
}
Once you have this change saved run composer update and let the package download
into the vendor app., (*4)
General Configuration
To begin you'll need to configure your service username, password and signature.
The configuration will need to look something like this:, (*5)
File: config/bootstrap.php, (*6)
/**
* Paypal WPP Payload
*/
Configure::write('PaypalWPP.username', 'username_api1.domain.com');
Configure::write('PaypalWPP.password', '5SWM6YY8YSUY888');
Configure::write('PaypalWPP.signature', 'tlArzO7mr5uXMO6.H2zPIuzAFYn4irhcVyzOPeiUcocJF.H3mGr');
Making a transaction to PayPal WPP
After the configuration is setup you'll want to connect to PayPal WPP using the
library., (*7)
File: src/Form/SalesForm.php, (*8)
<?php
namespace App\Form;
use Cake\Form\Form;
use Cake\Form\Schema;
use Cake\Validation\Validator;
use PaypalWPP\PaypalWPP;

/**

{

->addField('card_number', 'string')

}
/**

->notBlank('amount', __('Please enter an amount.'));
}
/**
* Execute Method.
*
* @param array $data
*
* @return bool
*/
protected function _execute(array $data)
{
$paypal = new PaypalWPP(Configure::read('PaypalWPP'));
$payment = $paypal->doDirectPayment($data);
if ($payment['ACK'] == 'Success') {
$this->parseData = [
'transaction_id' => $payment['TRANSACTIONID'],
];
return true;
} else {
$this->parseData = [
'failure_message' => $payment['L_LONGMESSAGE0'],
'failure_short' => $payment['L_SHORTMESSAGE0'],
];
}
return false;
}
/**
* Get Parse Data Method.
*
* @return string
*/
public function getParseData()
{
return $this->parseData;
}
}
File: src/Controller/SalesController.php, (*9)
<?php
namespace App\Controller;
use App\Form\SalesForm;
/**
* Sales Controller.
*/
class SalesController extends AppController
{
/**
* Add Method.
*/
public function add()
{
$sales = new SalesForm();
if ($this->request->is(['post', 'put'])) {
$transaction_execute = $sales->execute($this->request->data);
$transaction = $sales->getParseData();
if ($transaction_execute) {
$this->Flash->success(
__('Payment Completed Successfully: '.$transaction['transaction_id'])
);
$this->render('success');
} else {
$this->Flash->error(
__('Payment Failed: '.$transaction['failure_message'].'['.$transaction['failure_short'].']')
);
}
}
$this->set(compact('sales'));
}
}
