Does Umbraco give us any help when uploading files from an input type="file"? I'm happy saving the file once I've got hold of it, but trying to get my head around how to get it off the user's machine. Currently I only seem to get a string which is the file name, no path to stream it from nor file object. I feel I'm missing something somewhere. It's just a .net core Html.BeginForm posting to a Surface Controller.

There are a few different ways to do this. For one, you can get it from the request like this: https://github.com/skybrud/Skybrud.Umbraco.Redirects.Import/blob/v4/main/src/Skybrud.Umbraco.Redirects.Import/Controllers/RedirectsImportController.cs#L150

Thanks. It's empty 😦

var test = HttpContext.Request.Form.Files;

gives count 0 Now I've changed the model from "string" to "object" I get:-

var test = model.SinglePhoto;

which is also empty, whereas it gave the file name when it was a string.

Can you share some more code from your form?

Sure, it's a big form so I've just cut out the file upload bits and removed the classes for clarity....

@using (Html.BeginForm("Submit", "MemorialFormSurface", FormMethod.Post, new { @id=formId, enqType="multipart/form-data" })) {
    @Html.AntiForgeryToken()

    <div>
        <label asp-for="@Model.SinglePhoto">Please attach a photo of the person on their own.</label>
        <div>
            <input type="file" asp-for="@Model.SinglePhoto" data-val="false" data-val-required="Please select a single file in png, jpg, gif or webp format" accept=".jpg, .png, .gif, .webp">
            <span asp-validation-for="@Model.SinglePhoto" data-valmsg-replace="true"></span>
        </div>
    </div>

    <div>
        <label asp-for="@Model.OtherPhotos">Please attach up to 5 other photos of the person.</label>
        <div>
            <input type="file" asp-for="@Model.OtherPhotos" multiple data-val="false" data-val-required="Please select a single file in png, jpg, gif or webp format" accept=".jpg, .png, .gif, .webp">
            <span asp-validation-for="@Model.OtherPhotos" data-valmsg-replace="true"></span>
        </div>
    </div>        
}

How does the rendered HTML look? I'm noticing that both fields doesn't specify a name - but that might be set by the call to

asp-for="@Model.SinglePhoto"

The form tag looks like this:-

<form action="/umbraco/surface/memorialformsurface/Submit" enqType="multipart/form-data" id="a133e50a-432f-43f5-8fff-393a6985945a" method="post">

and the two file inputs look like this:-

<input type="file" data-val="false" data-val-required="Please select a single file in png, jpg, gif or webp format" accept=".jpg, .png, .gif, .webp" id="SinglePhoto" name="SinglePhoto">

<input type="file" multiple data-val="false" data-val-required="Please select a single file in png, jpg, gif or webp format" accept=".jpg, .png, .gif, .webp" id="OtherPhotos" name="OtherPhotos">

Shouldn't matter that it's in a partial

Here's the debug :-

How does your controller look? Changing the type to

IFormFile

sounds correct, but I can't get it to work with my test controller

Basically this....

using Microsoft.AspNetCore.Mvc;
using Umbraco.Cms.Core.Cache;
using Umbraco.Cms.Core.Logging;
using Umbraco.Cms.Core.Models;
using Umbraco.Cms.Core.Routing;
using Umbraco.Cms.Core.Services;
using Umbraco.Cms.Core.Web;
using Umbraco.Cms.Infrastructure.Persistence;
using Umbraco.Cms.Web.Website.Controllers;
using Web.Core.Models;
using Web.Core.Services;

namespace Web.Core.Controllers; 

public class MemorialFormSurfaceController : SurfaceController {
    
    private readonly IUmbracoContextAccessor _umbracoContextAccessor;
    private readonly IContentService _contentService;
    private readonly IMediaService _mediaService;
    private readonly Helpers _helpers;
    private readonly IWebHostEnvironment _environment;


    public MemorialFormSurfaceController(IUmbracoContextAccessor umbracoContextAccessor,
        IUmbracoDatabaseFactory databaseFactory,
        ServiceContext services,
        IContentService contentService,
        IMediaService mediaService,
        AppCaches appCaches,
        IProfilingLogger profilingLogger,
        IPublishedUrlProvider publishedUrlProvider,
        Helpers helpers,
        IWebHostEnvironment environment) : base(umbracoContextAccessor, databaseFactory, services, appCaches, profilingLogger, publishedUrlProvider) { 
        _umbracoContextAccessor = umbracoContextAccessor;
        _contentService = contentService;
        _mediaService = mediaService;
        _helpers = helpers;
        _environment = environment;
    }
    
    [HttpPost]
    public IActionResult Submit(MemorialFormModel model)
    {
        if (!ModelState.IsValid)
        {
            return CurrentUmbracoPage();
        }

    // All the other stuff......
}

Ok. Problem seems that the content type is

appplication/x-www-form-urlencoded

.

I hope it's not just that, I'll shoot myself, lol Trying now........

My model looks like this:

csharp
public class CraigModel {

    public IFormFile? SinglePhoto { get; set; }

    public List<IFormFile>? OtherPhotos { get; set; }

}

I don't see that, have just read back the thread, Ah, I showed you it earlier, maybe it works now, after the typo correction. ``var test = model.SinglePhoto;``

It's a rainy day, so just sitting inside watching some cycling and dabbling with some code :p
