在PHP中集成paynamics付款网关

Question

如何将paynamics集成为网站中的付款网关。 注意：Paynamics仅在菲律宾专属。

我有以下代码，但是在提交表单时，我总是遇到交易失败的情况，并且显示“签名验证失败”。 我不知道签名是否正确。

<?php 

$_mid = "xxxxxxxxxxxxxxxxxxx"; //<-- your merchant id
$_requestid = substr(uniqid(), 0, 13);

$b64string =  base64_encode($strxml);

 ?> 

这是提交表格：

<form name="surecollect" id="surecollect" method="post" action="https://testpti.payserv.net/webpaymentv2/default.aspx">
    <input type="hidden" name="paymentrequest" value="<?php echo $b64string; ?>">
    <input type="submit" name="submit" value="Submit">
</form>

设置到期限制：此功能将帮助date('yyyy-MMddTHH:mm')然后将有效的WAN IP设置为IP地址，并使用SSL设置URL。
