Help with Payment facility

Recommended Posts

Hi

 

I am setting up a site in Ireland using a credit card facility called Realex. They have given me some sample php code to generate a request & response for cc validation etc.

 

Could anyone have a look and maybe point me in the right direction to integrating this with osC?

 

Request php

// -------------------------------------------------------------

// Replace these with the values you receive from realex

$merchantid = "yourMerchantId";

$secret = "yourSecret";

 

$timestamp = strftime("%Y%m%d%H%M%S");

mt_srand((double)microtime()*1000000);

 

// ---------------------------------------------

// Replace these with the values you want to use

$orderid = $timestamp."-".mt_rand(1, 999);

$curr = "EUR";

$amount = "3000";

 

// ---------------------------------------------

$tmp = "$timestamp.$merchantid.$orderid.$amount.$curr";

$md5hash = md5($tmp);

$tmp = "$md5hash.$secret";

$md5hash = md5($tmp);

 

?>

 

</head>

 

<body bgcolor="#FFFFFF">

 

<form action=https://epage.payandshop.com/epage.cgi method=post>

 

<input type=hidden name="MERCHANT_ID" value="<?=$merchantid?>">

<input type=hidden name="ORDER_ID" value="<?=$orderid?>">

<input type=hidden name="CURRENCY" value="<?=$curr?>">

<input type=hidden name="AMOUNT" value="<?=$amount?>">

<input type=hidden name="TIMESTAMP" value="<?=$timestamp?>">

<input type=hidden name="MD5HASH" value="<?=$md5hash?>">

<input type=hidden name="AUTO_SETTLE_FLAG" value="1">

 

<input type=submit value="Proceed to secure server">

</form>

 

<font face=verdana>

<font size=3><b>php Sample - Realex Payments realAuth redirect</b></font>

<p>

<font size=2>Select View/Source to see the output

<ul>

<li>In the example I use the date/time and a random number as the order id - you

may have your own scheme.

<li>You should replace <code>merchantid</code> and <code>secret</code> with the

values provided by payandshop.com

</ul>

</font>

 

</body>

</html>

 

 

Response PHP

 

$timestamp = $TIMESTAMP;

$result = $RESULT;

$orderid = $ORDER_ID;

$message = $MESSAGE;

$authcode = $AUTHCODE;

$pasref = $PASREF;

 

// -------------------------------------------------------------

// Replace these with the values you receive from realexpayments

$merchantid = "yourMerchantId";

$secret = "yourSecret";

 

// ---------------------------------------------

$tmp = "$timestamp.$merchantid.$orderid.$result.$message.$pasref.$authcode";

$md5hash = md5($tmp);

$tmp = "$md5hash.$secret";

$md5hash = md5($tmp);

 

if ($md5hash != $MD5HASH) {

echo "hashes don't match - response not authenticated!";

}

 

// ---------------------------

// send yourself an email or send the customer an email

// or update a database or whatever you want to do here.

 

?>

 

<body bgcolor="#FFFFFF">

<font face=verdana,helvetica,arial size=2>

 

<?

if ($result == "00") {

?>

Hi Chris,

 

Did you ever get this to work ?

 

Thanks

 

 

 

 

I have made some headway into this but I have a problem. What do I pass for the 'order amount'  - what is the osCommerce variable etc that will give the correct order total.

 

i.e.

<input type=hidden name="AMOUNT" value="<?=$amount?>">

Hi

Any chance to get that code if you resolved it?

 

I installed a payment module (basically modifying an old one) and all is working fine BUT the MD5HASH thingy.

 

Have a look at this: the following code creates the hidden fields in the form. I manage to make all work, but the MD5HASH is not being calculated, as I just havent got a clue and add the code as is given by REALEX.

 

 

function process_button() {

global $HTTP_SERVER_VARS, $order, $customer_id;

 

$sequence = rand(1, 1000);

$process_button_string = tep_draw_hidden_field('customers_id', $customer_id) .

tep_draw_hidden_field('customers_name', $order->customer['firstname'] . ' ' . $order->customer['lastname']) .

tep_draw_hidden_field('customers_company', $order->customer['company']) .

tep_draw_hidden_field('customers_street_address', $order->customer['street_address']) .

tep_draw_hidden_field('customers_suburb', $order->customer['suburb']) .

tep_draw_hidden_field('customers_city', $order->customer['city']) .

tep_draw_hidden_field('customers_postcode', $order->customer['postcode']) .

tep_draw_hidden_field('customers_state', $order->customer['state']) .

tep_draw_hidden_field('customers_country', $order->customer['country']['title']) .

tep_draw_hidden_field('customers_telephone', $order->customer['telephone']) .

tep_draw_hidden_field('customers_email_address', $order->customer['email_address']) .

tep_draw_hidden_field('customers_address_format_id', $order->customer['format_id']) .

tep_draw_hidden_field('delivery_name', $order->delivery['firstname'] . ' ' . $order->delivery['lastname']) .

tep_draw_hidden_field('delivery_company', $order->delivery['company']) .

tep_draw_hidden_field('delivery_street_address', $order->delivery['street_address']) .

tep_draw_hidden_field('delivery_suburb', $order->delivery['suburb']) .

tep_draw_hidden_field('delivery_city', $order->delivery['city']) .

tep_draw_hidden_field('delivery_postcode', $order->delivery['postcode']) .

tep_draw_hidden_field('delivery_state', $order->delivery['state']) .

tep_draw_hidden_field('delivery_country', $order->delivery['country']['title']) .

tep_draw_hidden_field('delivery_address_format_id', $order->delivery['format_id']) .

tep_draw_hidden_field('billing_name', $order->billing['firstname'] . ' ' . $order->billing['lastname']) .

tep_draw_hidden_field('billing_company', $order->billing['company']) .

tep_draw_hidden_field('billing_street_address', $order->billing['street_address']) .

tep_draw_hidden_field('billing_suburb', $order->billing['suburb']) .

tep_draw_hidden_field('billing_city', $order->billing['city']) .

tep_draw_hidden_field('billing_country', $order->billing['country']['title']) .

tep_draw_hidden_field('billing_address_format_id', $order->billing['format_id']) .

tep_draw_hidden_field('payment_method', $order->info['payment_method']) .

tep_draw_hidden_field('cc_type', $order->info['cc_type']) .

tep_draw_hidden_field('cc_owner', $order->info['cc_owner']) .

tep_draw_hidden_field('realex_cc_owner', $HTTP_POST_VARS['realex_cc_owner']) .

tep_draw_hidden_field('realex_cc_number', $HTTP_POST_VARS['realex_cc_number']) .

tep_draw_hidden_field('realex_cc_expires_month', $HTTP_POST_VARS['realex_cc_expires_month']) .

tep_draw_hidden_field('realex_cc_expires_year', $HTTP_POST_VARS['realex_cc_expires_year']) .

tep_draw_hidden_field('cc_number', $this->cc_card_number) .

tep_draw_hidden_field('cc_expires', $this->cc_expiry_month . substr($this->cc_expiry_year, -2)) .

tep_draw_hidden_field('orders_status', $order->info['order_status']) .

tep_draw_hidden_field('CURRENCY', $order->info['currency']) .

tep_draw_hidden_field('currency_value', $order->info['currency_value']) .

tep_draw_hidden_field('ORDER_ID', $timestamp = strftime("%Y%m%d%H%M%S") . mt_srand((double)microtime()*1000000)."-".mt_rand(1, 999)) .

tep_draw_hidden_field('orders_status_id', $order->info['order_status']) .

tep_draw_hidden_field('MERCHANT_ID', MODULE_PAYMENT_REALEX_MERCHANT_ID) .

tep_draw_hidden_field('card_number', $this->cc_card_number) .

tep_draw_hidden_field('card_exp_date', $this->cc_expiry_month . substr($this->cc_expiry_year, -2)) .

tep_draw_hidden_field('description', MODULE_PAYMENT_REALEX_TEXT_DESCRIPTION_SHOP) .

tep_draw_hidden_field('cart_id', $this->cartID) .

tep_draw_hidden_field('AMOUNT', number_format($order->info['total'], 2)) .

tep_draw_hidden_field('comments', $order->info['comments']) .

tep_draw_hidden_field('TIMESTAMP', $timestamp = strftime("%Y%m%d%H%M%S") . mt_srand((double)microtime()*1000000)) .

tep_draw_hidden_field('MD5HASH', $md5hash =(

$tmp = "$timestamp.$merchantid.$orderid.$amount.$currency".

$md5hash = md5($tmp).

$tmp = "$md5hash.$secret".

$md5hash = md5($tmp))

) .

tep_draw_hidden_field('AUTO_SETTLE_FLAG', '0') .

tep_draw_hidden_field('x_email_merchant', ((MODULE_PAYMENT_REALEX_EMAIL_MERCHANT == 'True') ? 'TRUE' : 'FALSE'));

Does the code you have help me??

 

Once this is resolved, it will be turn into a contribution.
