                        <button type="button" class="btn-close" data-bs-dismiss="modal"
                            aria-label="Close"></button>
                    </div>
                    <div class="modal-body">
                        <div class="mb-3">
                            <label for="ID_produk" class="col-form-label">ID: </label>
                            <input type="text" class="form-control" name="ID_produk" id="ID_produk"
                                value="{{ $product->ID_produk }}">
                        </div>
                        <div class="mb-3">
                            <label for="nama_produk" class="col-form-label">Nama: </label>
                            <input type="text" class="form-control" name="nama_produk" id="nama_produk"
                                value="{{ $product->nama_produk }}">
                        </div>
                        {{-- <div class="mb-3">
                        <label for="gambar_produk" class="col-form-label">Gambar: </label>
                        <input type="file" class="custom-file-input" name="gambar_produk" id="gambar_produk">
                    </div> --}}
                        <div class="mb-3">
                            <label for="deskripsi_produk" class="col-form-label">Deskripsi:</label>
                            <textarea class="form-control" name="deskripsi_produk" id="deskripsi_produk" rows="10">
                                {{ $product->deskripsi_produk }}</textarea>
                        </div>
                        <div class="mb-3">
                            <label for="harga_produk" class="col-form-label">Harga: </label>
                            <input type="text" class="form-control" name="harga_produk" id="harga_produk"
                                value="{{ $product->harga_produk }}">
                        </div>
                        <div class="mb-3">
                            <label for="slug" class="col-form-label">Slug: </label>
                            <input type="text" class="form-control" name="slug" id="slug"
                                value="{{ $product->slug }}">
                        </div>
                        <div class="mb-3">
                            <label for="stock" class="col-form-label">Stock: </label>
                            <input type="text" class="form-control" name="stock" id="stock"
                                value="{{ $product->stock }}">
                        </div>
                    </div>
                    <div class="modal-footer">
                        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
                        <button type="submit" class="btn btn-primary">Submit</button>
                    </div>
                </form>
            </div>
        </div>
    </div>
@endforeach

2. Route

Route::resource('/admin/data-produk', AdminProdukController::class)->middleware('auth');

3. Controller

public function update(Request $request, Produk $product)
    {
        $validatedData = $request->validate([
            'nama_produk' => ['required'],
            'deskripsi_produk' => ['required'],
            'harga_produk' => ['required'],
            'slug' => ['required'],
            'stock' => ['required']
        ]);
        Produk::where('ID_produk', $product->ID_produk)
                ->update($validatedData);   
                
        return back()->with('berhasilEdit', 'Data produk berhasil diedit!');
    }

4. Model

class Produk extends Model{
    use HasFactory;
    
    protected $table = 'tabel_produk';
    protected $primaryKey = 'ID_produk';
    public $timestamps = false;
    protected $fillable = ['nama_produk',
    'deskripsi_produk',
    'harga_produk',
    'slug',
    'stock'
    ];
}

VALUE I do dd($validatedData); in controller after editing the value, and it shown here:

Answer 1

in your controller do this

    public function update(Request $request,$productID)
        {
            $validatedData = $request->validate([
                'nama_produk' => ['required'],
                'deskripsi_produk' => ['required'],
                'harga_produk' => ['required'],
                'slug' => ['required'],
                'stock' => ['required']
            ]);
        $product=Produk::find($productID);
        $product=$product->update($validateData);
        return back()->with('berhasilEdit', 'Data produk berhasil diedit!');
        }

after that if you do dd($product) you will get updated product Value
