Creating a form to Add List Item and to a Document Library

Question

Hi,  I'm super new to sharepoint , and have what is probably a newbie question.
I have a list and a document library.  The documents are linked to the items in the list. (1 list item may have one or moe documents associated with it).
I need to create a form to add new list items that will at the same time upload documents to the document library.
Do I use infopath for that?
Thanks

Hi,
According to your description, when adding a new item to the current list, you might want to upload the attachments of this item to other Document Library as well.
As a workaround, you can create an Event Receiver to capture the event when there is “An item was added”. In the Event Receiver, we can write C# code to copy the attachments
from a list item to a Document Library.
About how to create a simple Event Receiver in SharePoint 2013:

Here is the related code I use in this scenario, you can use it as a reference:
using System;
using System.Security.Permissions;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Utilities;
using Microsoft.SharePoint.Workflow;
namespace SharePointProject13.EventReceiver1
/// <summary>
/// List Item Events
/// </summary>
public class EventReceiver1 : SPItemEventReceiver
/// <summary>
/// An item is being updated.
/// </summary>
public override void ItemUpdating(SPItemEventProperties properties)
//base.ItemUpdating(properties);
/// <summary>
/// An item was added.
/// </summary>
public override void ItemAdded(SPItemEventProperties properties)
// base.ItemAdded(properties);
using (SPSite site = new SPSite("http://sp/"))
SPList docDestination = site.RootWeb.Lists["Document"];
SPList lstAttachment = site.RootWeb.Lists["List1"];
SPFolder fldRoot = site.RootWeb.Folders[docDestination.Title];
SPFileCollection flColl = null;
if (properties.ListItem.Attachments != null && properties.ListItem.Attachments.Count > 0)
foreach (String strName in properties.ListItem.Attachments)
flColl = fldRoot.Files;
SPListItem listtem = docDestination.Items.Add();
SPFile FileCopy = properties.ListItem.ParentList.ParentWeb.GetFile(properties.ListItem.Attachments.UrlPrefix + strName);
string destFile = flColl.Folder.Url + "/" + FileCopy.Name;
byte[] fileData = FileCopy.OpenBinary();
SPFile flAdded = flColl.Add(destFile, fileData, site.RootWeb.CurrentUser, site.RootWeb.CurrentUser, Convert.ToDateTime(properties.ListItem[SPBuiltInFieldId.Created]), Convert.ToDateTime(properties.ListItem[SPBuiltInFieldId.Modified]));
SPListItem item = flAdded.Item;
item[SPBuiltInFieldId.Created] = Convert.ToDateTime(properties.ListItem[SPBuiltInFieldId.Created]);
item[SPBuiltInFieldId.Modified] = Convert.ToDateTime(properties.ListItem[SPBuiltInFieldId.Modified]);
flAdded.Item.Update();
How it works in my environment:
Add an item with attachment in List1:
In the Document Library, we can see the uploaded attachment there:
