最近改用智付寶串金流，有依照他們提供的API文件做串接，但是不知道為甚麼還是有很多地方出現問題。

以下列出我遇到的問題：
1.付款方式有設定信用卡一次付款，但是到了支付頁面卻還是出現其他全部的付款方式
2.依照文件設定ReturnURL但是付款完畢後卻沒重導向指定網址
3.依照文件設定NotifyURL吃不到支付寶POST回來的參數
4.已經讓EmailModify等於0，表示我不想讓使用者在支付頁面可以再填寫一次Email，可是卻沒效，使用者仍然還是要再填一次

我的Form程式碼：

<form name="newebpay" method="post" action="https://ccore.newebpay.com/MPG/mpg_gateway" id="newebpay" class="d-none">
    <input type="hidden" name="MerchantID" value="...">
    <input type="hidden" name="RespondType" value="JSON">
    <input type="hidden" name="TimeStamp" value="1561712191">

    <input type="hidden" name="MerchantOrderNo" value="926x58834852">
    <input type="hidden" name="Amt" value="335">
    <input type="hidden" name="ItemDesc" value="冰山紅火焰">
    <input type="hidden" name="TradeLimit" value="900">

    <input type="hidden" name="CREDIT" value="1">
    <input type="submit" value="submit">
</form>

回傳參數接收程式碼：

public function catch($arg = []) //接收回傳參數的function
{
    $json = $_POST['JSONData'];
    $enjson = json_decode($json);

    $orderId = $arg['orderId'];
    $type = $arg['type'];

    $OrderField = OrderField::orm( $orderId );

    if( $enjson->Status == 'SUCCESS' )
    {
        $OrderField->responseStatus = $enjson->Status;
        $OrderField->responseMsg = $enjson->Message;
        $OrderField->amt = $enjson->Amt;
        $OrderField->tradeNo = $enjson->TradeNo;
        $OrderField->payTypeRespond = $enjson->PaymentType;
        $OrderField->PayTime = $enjson->PayTime;
        $OrderField->cardFourNo = $enjson->Card4No;
        $OrderField->creditAmountRespond = $enjson->Inst;
        $OrderField->stast = $enjson->InstFirst;
        $OrderField->staed = $enjson->InstEach;
        $OrderField->paycheckStatus = 1;
        $OrderField->save();
    }
    else
    {
        $OrderField->paycheckStatus = 3;
        $OrderField->save();
    }
}
