Codeigniter Payments

CodeIgniter Payments is an abstraction library for supporting multiple payments providers. The project began in February 2011 as a CodeIgniter library and has since evolved into a framework agnostic payments engine with support for CodeIgniter.

At time of writing, the following gateways are supported, but it's very possible more gateways have been added since:

• PayPal Payments Pro
• Authorize.net (AIM)
• Psigate
• Beanstream
• QuickBooks Merchant Services
• Eway (Australia)
• Amazon SimplePay
• Stripe
• Google Checkout
• GoCardless
• Braintree Payments
• BluePay

NOTICE - USING CODEIGNITER-PAYMENTS ALONE DOES NOT MAKE YOU PCI COMPLIANT

It is highly recommended that you attempt to architect your application to achieve some level of PCI compliance. Without this, the applications you create can be vulnerable to fines for PCI compliance violations. Using codeigniter-payments does not circumvent the need for you to do this. You can check out the PCI compliance self assessment form here: https://www.pcisecuritystandards.org/merchants/self_assessment_form.php

Installing

Available via Sparks. For info about how to install sparks, go here: http://getsparks.org/install

You can then load the spark with this:

$this->load->spark('codeigniter-payments/[version #]/');

IMPORTANT!

1. If you want to test locally (and you should), you need to set "force_secure_connection" to FALSE in config/payments.php

2. By default, test api endpoints will be used. To enable production endpoints, change the mode in /config/payments.php from 'test' to 'production'. Note that if you are a Psigate customer, you must obtain your production endpoint from Psigate support.

3. When you load gateways, the config can either be passed in the constructor or loaded from a config file.

Gateway Support

The following gateways are supported:

Method Support List

This is constantly changing. Please visit http://payments.calvinfroedge.com or run php doxgen.php in the src/php-payments/documentation folder to see the latest documentation.

Configuration

To create a config file, copy a config file from src/php-payments/config/drivers for a driver you want to use into the spark config folder. The name of the file should stay the same. You will, however, need to make each param inside the config file reside inside a an array matching the gateway name. For example:

$config = array(
	'authorize_net' => array(
		'config1' => 'This is the config param'
	)
);

If you don't pass config in an array, and don't create a config file, the config in src/php-payments/config/drivers will be used - which is only for testing and is probably not what you want.

Making Requests

A request is formatted thusly:

$this->payments->payment_action('gateway_name', $params, $config);

Note that the third array for config is optional.

Responses

There are two types of responses returned, local responses and gateway responses. If a method is not supported, required params are missing, a gateway does not exist, etc., a local response will be returned. This prevents the transaction from being sent to the gateway and the gateway telling you 3 seconds later there is something wrong with your request.:

'type'				=>	'local_response',  //Indicates failure was local
'status' 			=>	$status, //Either success or failure
'response_code' 	=>	$this->_response_codes[$response], 
'response_message' 	=>	$this->_response_messages[$response],
'details'			=>	$response_details

Access response properties by naming your call something like this:

$response = $this->payments->payment_action('gateway_name', $params); 

Then you can do:

$status = $response->status;

Gateway responses will usually have a full response from the gateway, and on failure a 'reason' property in the details object:

'type'				=>	'gateway_response',
'status' 			=>	$status, 
'response_code' 	=>	$this->_response_codes[$response], 
'response_message' 	=>	$this->_response_messages[$response],
'details'			=>	$details

You can access this like $response->details->reason. You may want to save the full gateway response (it's an array) in a database table, you can access it at $response->details->gateway_response
