How to restrict file being uploaded to Media Library folder in WFFM MVC

Question

By default files are getting uploaded to the media library folder. How do I make WFFM upload the files to a different path by default? This is in MVC WFFM forms.

Answer 1

One of the properties on the File upload field type is Upload to. Select the elipsis then set the correct folder in the media library from the dialog.

Don't forget to publish the form.

If you want to always default the value a different folder then you will need to override the field and the attributes of the UploadTo property.

Create a class with the following, which will be used in the Form Designer interface and WebForms implementations:

using System.ComponentModel;
using Sitecore.Form.Core.Attributes;
using Sitecore.Form.Core.Visual;

namespace MyProject.CMS.Custom.WFFM.Fields
{
    public class FileUpload : Sitecore.Form.Web.UI.Controls.UploadFile
    {
        private string uploadDir = "/sitecore/media library/Uploads";

        [VisualCategory("Upload")]
        [VisualProperty("Upload To:", 0)]
        [VisualFieldType(typeof(SelectDirectoryField))]
        [DefaultValue("/sitecore/media library/Uploads")]
        public new string UploadTo
        {
            get
            {
                return this.uploadDir;
            }
            set
            {
                this.uploadDir = value;
            }
        }
    }
}

Create another class for MVC implementation:

using System.ComponentModel;

namespace MyProject.CMS.Custom.WFFM.Fields
{
    public class FileUploadField : Sitecore.Forms.Mvc.ViewModels.Fields.FileUploadField
    {
        [DefaultValue("/sitecore/media library/Uploads")]
        public string UploadTo { get; set; }

        public FileUploadField()
        {
            if (!string.IsNullOrEmpty(this.UploadTo))
                return;
            this.UploadTo = "/sitecore/media library/Uploads";
        }
    }
}

Set the DefaultValue and other properties to whatever your default folder should be.

Next update the File Upload field located at /sitecore/system/Modules/Web Forms for Marketers/Settings/Field Types/Simple Types/File Upload with the details of your assembly:

• Assembly: MyProject.CMS.Custom
• Class: MyProject.CMS.Custom.WFFM.Fields.FileUpload
• MVC Type: MyProject.CMS.Custom.WFFM.Fields.FileUploadField, MyProject.CMS.Custom

NOTE: It is recommended that instead of directly updating the above field you instead make a copy and use that copy throughout your forms instead. The downside if you'll have 2 file upload type fields available, but you also risk potential issues if an upgrade modifies this field type.
