Hi Everyone,
I am new to lightning component, i have written code for upload multiple files upload. But for me working only single file upload. Can anybody help me to resolve this issue. Below are the code details:

   @AuraEnabled
    public static ID saveAccount(RFP_Request__c accRec, RFP_Request__c rfplkp)
    {
        try
        {
            accRec.RFP_Manager__c=rfplkp.RFP_Manager__c;
            insert accRec;
        }
        catch(Exception e)
        {
            system.debug('e-->' + e.getMessage());
        }

        return accRec.Id;
    }
    @AuraEnabled
    public static Id saveChunk(Id parentId, String fileName, String base64Data, String contentType, String fileId) {
        // check if fileId id ''(Always blank in first chunk), then call the saveTheFile method,
        //  which is save the check data and return the attachemnt Id after insert,
        //  next time (in else) we are call the appentTOFile() method
        //   for update the attachment with reamins chunks
        if (fileId == '') {
            fileId = saveTheFile(parentId, fileName, base64Data, contentType);
        } else {
            appendToFile(fileId, base64Data);
        }
   return Id.valueOf(fileId);
    }
   public static Id saveTheFile(Id parentId, String fileName, String base64Data, String contentType) {
        base64Data = EncodingUtil.urlDecode(base64Data, 'UTF-8');
   Attachment oAttachment = new Attachment();
        oAttachment.parentId = parentId;
   oAttachment.Body = EncodingUtil.base64Decode(base64Data);
        oAttachment.Name = fileName;
        oAttachment.ContentType = contentType;
   insert oAttachment;
   return oAttachment.Id;
    }
   private static void appendToFile(Id fileId, String base64Data) {
        base64Data = EncodingUtil.urlDecode(base64Data, 'UTF-8');
   Attachment a = [
            SELECT Id, Body
            FROM Attachment
            WHERE Id =: fileId
        ];
   String existingBody = EncodingUtil.base64Encode(a.Body);
   a.Body = EncodingUtil.base64Decode(existingBody + base64Data);
   update a;
    }
  }
