WooCommerce Custom Payment Gateway - wordpress

Question

I am trying to make a Custom Gateway Plugin for my Merchant Account but I got stuck and I don't know how to continue.
Now, here is what I done so far:
<?php
/*
Plugin Name: Paysecure.ro Payment Gateway
Plugin URI: http://www.Paysecure.ro
Description: Allows you to use Paysecure.ro Payment Gateway with the WooCommerce plugin.
Version: 0.0.1
Author: Andrei Raileanu
*/
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
add_action('plugins_loaded', 'woocommerce_Paysecure', 0);
function woocommerce_Paysecure(){
if (!class_exists('WC_Payment_Gateway'))
return; // if the WC payment gateway class is not available, do nothing
if(class_exists('WC_Paysecure'))
return;
class WC_Gateway_Paysecure extends WC_Payment_Gateway{
public function __construct(){
$plugin_dir = plugin_dir_url(__FILE__);
global $woocommerce;
$this->id = 'Paysecure';
$this->icon = apply_filters('woocommerce_Paysecure_icon', ''.$plugin_dir.'Paysecure.png');
$this->has_fields = true;
// Load the settings
$this->init_form_fields();
$this->init_settings();
// Define user set variables
$this->title = "Credit/Debit Card";
$this->description = "You will be redirected to paysecure.ro to complete your purchase.";
$this->cui = "XXXXXXXXX";
$this->encryption_key = "XXXXXXXXX";
$this->currency = "USD";
// Logs
if ($this->debug == 'yes'){
$this->log = $woocommerce->logger();
}
// Actions
add_action('woocommerce_receipt_' . $this->id, array($this, 'receipt_page'));
// Save options
add_action( 'woocommerce_update_options_payment_gateways_' . $this->id, array( $this, 'process_admin_options' ) );
// Payment listener/API hook
add_action('woocommerce_api_wc_' . $this->id, array($this, 'check_ipn_response'));
}
function init_form_fields()
{
$this->form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable', 'woocommerce' ),
'type' => 'checkbox',
'label' => __( 'Enable Paysecure', 'woocommerce' ),
'default' => 'yes'
)
);
}
public function admin_options() {
?>
<h3><?php _e( 'Paysecure', 'woocommerce' ); ?></h3>
<p><?php _e( 'Paysecure Payment Gateway', 'woocommerce' ); ?></p>
<table class="form-table">
<?php $this->generate_settings_html(); ?>
</table>
<?php
}
function payment_fields() {
$plugin_dir = plugin_dir_url(__FILE__);
// Description of payment method from settings
if ($this->description) { ?>
<p><?php
echo $this->description; ?>
</p><?php
} ?>
<?php
}
function process_payment( $order_id ) {
global $woocommerce;
$order = new WC_Order($order_id);
// I WILL NEED THESE FIELDS
//$this->notify_url;
//$order->get_total();
//$order->get_order_number();
//$order->billing_first_name;
//$order->billing_email;
}
}
function add_Paysecure_gateway($methods){
$methods[] = 'WC_Gateway_Paysecure';
return $methods;
}
add_filter('woocommerce_payment_gateways', 'add_Paysecure_gateway');
}
Here are the PHP instructions from my merchant account provider:
<?php
require_once('./functions.php');
$key = 'THIS IS THE ENCRYPTION KEY';
$data = array( 'cui' => 'THIS IS THE CUI CODE',
'AMOUNT' => '200',
'CURRENCY' => 'USD',
'ORDER' => '12313',
'DESC' => ps_clean('SHORT DESCRIPTION'),
'PENTRU' => 'EMAIL ADDRESS',
'TRTYPE' => 0,
'BACKREF' => 'http://www.site.ro/test.php',
'TIMESTAMP'=>time()
);
echo '<form action="https://paysecure.ro/order/cgi-bin/" method="post" >';
foreach ($data as $l => $v ) echo '<input size="55" readonly type="text" name="'.$l.'" value="'.$v.'" /> : <label for="'.$l.'">'.$l.'</label><br>';
echo '<input size="55" type="text" name="P_SIGN" readonly value="'.calculateSign($data,$key).'" /><br>' ; //se calculeaza P_SIGN - ul , encriptarea datelor
?>
<input type="submit" />
</form>
Can someone help me with the rest of the code?

Answer 1

1st mistake I noticed you made, $this->id MUST be in lowercase. 'Paysecure' is not gonna work here come time for the API hook.
// Payment listener/API hook
add_action('woocommerce_api_wc_' . $this->id, array($this, 'check_ipn_response'));
change to this instead:
// Payment listener/API hook
add_action('woocommerce_api_wc_paysecure', array($this, 'check_ipn_response'));
2nd mistake is that you forgot to create the function check_ipn_response()
// Handles the callbacks received from the payment backend. give this url to your payment processing comapny as the ipn response URL:
// USAGE: http://myurl.com/?wc-api=WC_Gateway_Paysecure
function check_ipn_response() {
$http_contents = file_get_contents("php://input");
$json = json_decode($http_contents, true);
$order = new WC_Order($json['custom']);
if ($callback_json['status'] == 'Transaction approved')
{
$order->payment_complete(); //This will ensure stock reductions are made, and the status is changed to the correct value.
$order->add_order_note( __( 'KiwiPay Transaction Approved.', 'kiwipay' ) );
}
else
{
$order->update_status('failed');
$order->add_order_note('KiwiPay status received - ' . $callback_json['status']);
}

How about this?
add_action( 'plugins_loaded', 'init_gateway_cash' );
function init_gateway_cash() {
class WC_Gateway_Cash extends WC_Payment_Gateway {
function __construct() {
$this->id = "Cash Gateway";
$this->title = "Cash";
$this->description = "More later";
$this->init_form_fields();
$this->init_settings();
add_action( 'woocommerce_update_options_payment_gateways', array( &$this, 'process_admin_options' ) );
}
function init_form_fields(){
$this->form_fields = array(
'enabled' => array(
'title' => __( 'Enable/Disable', 'woocommerce' ),
'type' => 'checkbox',
'label' => __( 'Enable Cheque Payment', 'woocommerce' ),
'default' => 'yes'
),
'title' => array(
'title' => __( 'Title', 'woocommerce' ),
'type' => 'text',
'description' => __( 'This controls the title which the user sees during checkout.', 'woocommerce' ),
'default' => __( 'Cheque Payment', 'woocommerce' ),
'desc_tip' => true,
),
'description' => array(
'title' => __( 'Customer Message', 'woocommerce' ),
'type' => 'textarea',
'default' => ''
)
);
}
function process_payment( $order_id ) {
global $woocommerce;
$order = new WC_Order( $order_id );
$productArray = array();
$x = 0;
foreach( $order->get_items() as $item_id => $item ) {
$productArray[$x] = $order->get_product_from_item( $item );
$x++;
}
// Mark as on-hold (we're awaiting the cheque)
$order->update_status('on-hold',
__( 'Awaiting cheque payment.', 'woocommerce' )
);
// Remove cart
$woocommerce->cart->empty_cart();
// Return thankyou redirect
return array(
'result' => 'success',
'redirect' => $this->get_return_url( $order )
);
}
}
}
function add_gateway_cash_class ($methods ) {
$methods[] = 'WC_Gateway_Cash';
return $methods;
}
add_filter( 'woocommerce_payment_gateways', 'add_gateway_cash_class' );
