'how can i show the data that the user entered in the file input when he want to edit it
for your information the file is saved as a binary data
here is is the model:
public class Movie
{
[Key]
public int MovieId { get; set; }
public string MovieName { get; set; }
public string MovieDescription { get; set; }
public byte[] MovieImage { get; set; }
public string MovieTrailer { get; set; }
//FK
public int AdminId { get; set; }
//Navigation
public Admin Admin { get; set; }
public ICollection<Event> Events { get; set; }
public AddingCategory AddingCategory { get; set; }
public ViewingMovie ViewingMovie { get; set; }
}
}
And here is the controller :
public async Task<IActionResult> Edit(int? id)
{
if (id == null)
{
return NotFound();
}
var movie = await _context.tblMovies.FindAsync(id);
if (movie == null)
{
return NotFound();
}
ViewData["AdminId"] = new SelectList(_context.Set<Admin>(), "AdminId", "Email", selectedValue: movie.AdminId);
return View(movie);
}
// POST: Movies/Edit/5
// To protect from overposting attacks, enable the specific properties you want to bind to.
// For more details, see http://go.microsoft.com/fwlink/?LinkId=317598.
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Edit(int id, [Bind("MovieId,MovieName,MovieDescription,MovieImage,MovieTrailer,AdminId")] Movie movie, IFormFile MovieImage)
{
if (id != movie.MovieId)
{
return NotFound();
}
if (MovieImage != null)
{
//This code is used to copy image to DataBase
using (var myStream = new MemoryStream())
{
await MovieImage.CopyToAsync(myStream);
movie.MovieImage = myStream.ToArray();
}
}
if (ModelState.IsValid)
{
try
{
_context.Update(movie);
await _context.SaveChangesAsync();
}
catch (DbUpdateConcurrencyException)
{
if (!MovieExists(movie.MovieId))
{
return NotFound();
}
else
{
throw;
}
}
return RedirectToAction(nameof(Index));
}
ViewData["AdminId"] = new SelectList(_context.Set<Admin>(), "AdminId", "Email", movie.AdminId);
return View(movie);
}
and the last here is the edit view:
<div class="row">
<div class="col-md-4">
<form asp-action="Edit" method="post" enctype="multipart/form-data">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
