I need a custom payment module

[lowell]

I need a custom payment module for a tradeorganisation.
I have installed External Order Number Generator for my credit card system.

The information that needs to be send is:

orderid: The internal ordernumber.
amount: The amount without decimals. KR 249,50 must be 24950
merchant: The membernumber for my shop.
md5key: Optional.

The informations are to be send via a form.

Example:

<form action="https://www.eksempel.dk/payment.php" method="POST">
<input type="hidden" name="orderid" value="12345">
<input type="hidden" name="merchant" value="600325">
<input type="hidden" name="amount" value="24950">
<input type="hidden" name="md5key" value="684sd694sw98g4sagadghh">
<input type="submit" value="Pay">
</form>


When payment is done, customer will be returned to "accepturl" (a value chosen from a controlpanel at the paymentprovider) with an MD5-code (md5), transaction id (transact) and optional parameters.

If the customer cancels the payment, he will be returned to "cancelurl" (as accepturl above).
