How to create new payment module?

[mscro]

Hi all,

I am busy a long time to make new payment module for our shop but don't work.

I try edit and change some payment modules what I download here from the site but still no success. Is some manual how I can create new payment module + order page???

I checked https://www.zen-cart.com/tutorials/i...hp?category=12 but nothing.

There's a very basic outline of their structure here.

tnx kuroi,

these basis i found in all payment options what i have eddit and try till now.

I try to find some options and codes,
as sample i was busy testing :



vxsbill.php ;;


class vxsbill {
var $code, $title, $description, $enabled, $sort_order;


// class constructor

function vxsbill() {
global $order, $_POST;

$this->code = 'vxsbill';
$this->title = MODULE_PAYMENT_VXS_TEXT_TITLE;
$this->description = MODULE_PAYMENT_VXS_TEXT_DESCRIPTION;
$this->sort_order = MODULE_PAYMENT_VXS_SORT_ORDER;
$this->enabled = ((MODULE_PAYMENT_VXS_STATUS == 'True') ? true : false);

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

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

$this->form_action_url = 'vxs_process.php';

}



function process_button() {

global $_POST, $order;



$process_button_string =
zen_draw_hidden_field('desc', 'Purchase from ' . STORE_NAME) .
zen_draw_hidden_field('amount', $order->info['total']) ;
return $process_button_string ;
return false;
}




vxs_process.php



$username = MODULE_PAYMENT_VXS_USER;
$password = MODULE_PAYMENT_VXS_PASS;
$site = MODULE_PAYMENT_VXS_SITE;
$package = MODULE_PAYMENT_VXS_PACKAGE;

$price = $_POST['amount'];
$description = urlencode($_POST['desc']);

$result = "";

$spwprice = $price*100;

$request = "https://secure.vxsbill.com/create_order.php3?......;


..

my question is where i can find list with more info about these functions: zen_session_register
zen_draw_hidden_field

$this->description = MODULE_PAYMENT_XXXX_TEXT_DESCRIPTION;
$this->sort_order = MODULE_PAYMENT_XXXX_SORT_ORDER;
$this->enabled = ((MODULE_PAYMENT_XXXX_STATUS == 'True') ? true : false);



tnx

zen_draw_hidden_field

They are defined in the admin/includes/functions/sessions.php and admin/includes/functions/html_output.php files respectively.

I have an SDK from SLIM CD which is my client's gateway. I have all the puzzle pieces but I don't know what to do with them to make the payment module.

I know some php and mysql, but need more of a 1.2.3. type tutorial to see what to do. anysuggestions would be most appreciated

I'm afraid that you're looking for something that doesn't exist, and maybe can't exist. There are certainly hundreds and possibly thousands of payment gateways out there each with their own idiosyncrasies.

There is a general structure for Zen Cart payment modules which is outlined in the Wiki entry I referenced earlier. But a 1.2.3 guide that went beyond this would either be so general as to not really tell you very much, or if it tried to deal with the complexities introduced by different gateway APIs would be overwhelmingly complex.

On those rare occasions that I've written payment modules (not a favorite job) I just focus on the specifics of the one in front of me and concentrate on mapping their API (usually well described in their documentation) to Zen Cart's payment mod structure (outlined in the Wiki).
