HTML Generation Sample Code
Below is a code snippet that demonstrates how the webpage that posts to Certegy might be generated:
private function postToCheckout($checkoutUrl, $payload)
{
echo
"<html>
<body>
<form id='form' action='$checkoutUrl' method='post'>";
foreach ($payload as $key => $value) {
echo "<input type='hidden' id='$key' name='$key' value='$value'/>";
}
echo
'</form>
</body>';
echo
'<script>
var form = document.getElementById("form");
form.submit();
</script>
</html>';
}
