Question

继承了Theme.php的整个代码，我只是想知道如何获取包含产品名称的输入类型图像的值，但是它是使用循环显示的

let params = "<ItemTrackingDetailsRequest>
        <ItemTrackingNumbers>
        <TrackingNumber>\(trackingNumber.uppercaseString)</TrackingNumber>
        </ItemTrackingNumbers>
        </ItemTrackingDetailsRequest>"

        let xmlRequest = NSMutableURLRequest(URL: NSURL(string: url)!)
        xmlRequest.HTTPBody = params.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
        xmlRequest.HTTPMethod = "POST"
        xmlRequest.addValue("application/xml", forHTTPHeaderField: "Content-Type")

我需要获取sumbit表单的值，特别是输入类型图像的产品名称

但我总是得到产品名称的最后一个值

Answer 1

是的，这是因为您将SaveFormTheme函数定义为每个项目的全局函数，因此在执行SaveFormTheme()时始终只调用最后一个函数。要解决此问题，请在函数名称中包含一些itemID或$counter，这样您就可以SaveFormTheme1()，SaveFormTheme2()等。
