Question

以下是我发送给SOAP Web服务的请求。根据WSDL，当我使用PostTransaction时，它允许每个事务1个'CheckDetailEntries'实例。

<s:complexType name="PostTransactionRequest">
        <s:sequence>
          <s:element minOccurs="1" maxOccurs="1" name="RequestHeader" nillable="true" type="tns:RequestHeader" />

          <s:element minOccurs="1" maxOccurs="1" name="CheckDetailEntries" nillable="true" type="tns:ArrayOfChoice1" />
          <s:element minOccurs="1" maxOccurs="1" name="CheckHeaderRequest" nillable="true" type="tns:CheckHeaderRequest" />
          <s:element minOccurs="1" maxOccurs="1" name="OrderTypeNumber" type="s:unsignedByte" />
        </s:sequence>

它说CheckDetailEntries是type =“tns：ArrayOfChoice1”。我该如何处理选择？目前我通过$request->REQ->CheckDetailEntries = new CheckDetailEntries();启动CheckDetailEntries，它适用于一个项目，但当我尝试做两个项目时，我收到错误。我错过了什么吗？

我的PHP代码：

$request = new PostTransaction();
        $request->REQ = new PostTransactionRequest();
        $request->REQ->RequestHeader = new RequestHeader();

        $request->REQ->RequestHeader->InterfaceVersion = $this->GetVersion($clientName)->data->interfaceVersion;
        $request->REQ->RequestHeader->ClientName = $clientName;

        $request->REQ->CheckDetailEntries = new CheckDetailEntries();

        $request->REQ->CheckDetailEntries->MenuItem = new MenuItem();
        $request->REQ->CheckDetailEntries->MenuItem->ReferenceEntry = "Item";
        $request->REQ->CheckDetailEntries->MenuItem->Count = "1";
        $request->REQ->CheckDetailEntries->MenuItem->Price = "1.67";
        $request->REQ->CheckDetailEntries->MenuItem->ItemNumber = "112001";
        $request->REQ->CheckDetailEntries->MenuItem->PriceLevel = "1";
        // Here is the problem. How can I have multiple Items?
        $request->REQ->CheckDetailEntries->MenuItem = new MenuItem();
        $request->REQ->CheckDetailEntries->MenuItem->ReferenceEntry = "Item";
        $request->REQ->CheckDetailEntries->MenuItem->Count = "1";
        $request->REQ->CheckDetailEntries->MenuItem->Price = "1.67";
        $request->REQ->CheckDetailEntries->MenuItem->ItemNumber = "125004";
        $request->REQ->CheckDetailEntries->MenuItem->->MenuItem->PriceLevel = "1";

WSDL（必须剥离一些以适应体内30,000字符要求）：
