Web Forms for Marketers 8.1 update 3中的文件上载字段验证

Question

我正在尝试使用网络表单在sitecore 8中进行文件上传验证，但它不起作用请向我推荐解决方案。这是我的代码。

library(bizdays)

load_rmetrics_calendars(2014)

mutate(df2, 
       nbd_time=following(time_seq, 'Rmetrics/NERC'),
       nbd_time=ifelse(nbd_time==time_seq, offset(time_seq, 1, 'Rmetrics/NERC'), nbd_time),
       nbd_time=as.Date(nbd_time, origin="1970-01-01"),
       nbddow=wday(nbd_time, label=TRUE))

  

创建RestrictedUploadField类

namespace Test.Web.WFFM
{
  [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field)]
  public class LimitFileSizeAttribute : DynamicValidationBase
  {

    private const string FileSizeLimitKey = "filesizelimit";
    private const string ErrorMessageKey = "filesizelimiterror";

    protected override ValidationResult ValidateFieldValue(IViewModel model, object value, ValidationContext validationContext)
    {

        // Required attribute should handle null value
        if (value == null)
        {
            return ValidationResult.Success;
        }

        var fileBase = value as HttpPostedFileBase;
        if (fileBase == null)
        {
            return new ValidationResult(ErrorMessage);
        }

        var fileUploadField = validationContext.ObjectInstance as FileUploadField;
        var limit = GetLimit(fileUploadField);

        if (limit == -1) // Limit not set
        {
            return ValidationResult.Success;
        }

        if (fileBase.ContentLength > limit)
        {
            return new ValidationResult(GetErrorMessage(fileUploadField));
        }

        return ValidationResult.Success;
    }

    private static int GetLimit(IViewModel field)
    {
        if (field == null || !field.Parameters.ContainsKey(FileSizeLimitKey))
        {
            return -1;
        }

        var parameter = field.Parameters[FileSizeLimitKey];
        int intValue;
        if (int.TryParse(parameter, out intValue))
        {
            return intValue;
        }

        return -1;
    }

    private string GetErrorMessage(IViewModel field)
    {
        if (field != null && field.Parameters.ContainsKey(ErrorMessageKey))
        {
            return field.Parameters[ErrorMessageKey];
        }

        return ErrorMessage;
    }
}}

  

在sitecore中创建自定义验证并添加“参数”和“本地化参数”

创建自定义字段类型“Restricted File Upload”，在“验证”字段中添加验证，添加“参数”和“本地化参数”。
