Help with ZIPCASH payment gateway

[nnitin]

Hi All,

I want to add a zipcash payment module. It is basically a web interface where customer enters his mobile number and pays via SMS. Is there any tutorial to add new payment method? They need following info via hhtp post:

mercode - Merchant Code provided by Zipcash
amount - Transaction Amount in Rupees. A two digit paisa component can also be added if required.
txcode – Transaction Reference Code generated by merchant (without any spaces)
details – This parameter is used to described the transaction (eg. Movie Tickets, Air Tickets etc.)
RU – Optional parameter – Return url
Use the HTTP-POST method to post the data.

How do I create a module for this type of payment?

Regards,

Hi All,

Well I have figured out how to make this module and have developed some code for this payment method. I have cloned ccavenue module available in download section. However after making the payment and the confirmation from the payment gateway, I come back to my shop but, the transaction is not completed and the item remains in the shopping cart.

What mistake am I making?

If I am able to make this successful I would like to offer this as an adon module for zipcash.

Regards,

Hi All,

I have cloned ccavenue payment module to suit ZIPCASH payment module.


Sending data from Zencart to zipcash payment gateway works. When the user pays the amount and complestes the transaction it comes back to zencart with return url. However it can not update the order. The payment gateway sends to zencart following information to zencart

txcode – Transaction Reference Code sent by merchant
statuscode – Success code – 101 Failure code – 110
ziptxncode - Zipcash transaction code
amount

I feel when it comes to "checkout_payment.php" the headers will process the info. I tried it but the order remains in the shopping cart.

Where am I making a mistake?

Here is the code:

<?php


  class zipcash extends base{
    var $code, $title, $description, $enabled;

// class constructor
    function zipcash() {
      $this->code = 'zipcash';
      $this->title = MODULE_PAYMENT_ZIPCASH_TEXT_TITLE;
      $this->description = MODULE_PAYMENT_ZIPCASH_TEXT_DESCRIPTION;
      $this->sort_order = MODULE_PAYMENT_ZIPCASH_SORT_ORDER;
      $this->enabled = ((MODULE_PAYMENT_ZIPCASH_STATUS == 'True') ? true : false);

      if ((int)MODULE_PAYMENT_ZIPCASH_ORDER_STATUS_ID > 0) {
        $this->order_status = MODULE_PAYMENT_ZIPCASH_ORDER_STATUS_ID;
      }

      if (is_object($order)) $this->update_status();

$this->form_action_url = 'http://www.zipcash.in/PG2Test/PayByZipcash.aspx';
    }

// class methods
    function update_status() {
     global $order, $db;

      if ( ($this->enabled == true) && ((int)MODULE_PAYMENT_ZIPCASH_ZONE > 0) ) {
        $check_flag = false;
        $check_query = $db->Execute("select zone_id from " . TABLE_ZONES_TO_GEO_ZONES . " where geo_zone_id = '" . MODULE_PAYMENT_ZIPCASH_ZONE . "' and zone_country_id = '" . $order->delivery['country']['id'] . "' order by zone_id");
        while ($check = mysql_fetch_array($check_query)) {
          if ($check['zone_id'] < 1) {
            $check_flag = true;
            break;
          } elseif ($check['zone_id'] == $order->delivery['zone_id']) {
            $check_flag = true;
            break;
          }
        }

        if ($check_flag == false) {
          $this->enabled = false;
        }
      }

// disable the module if the order only contains virtual products
