Setelah fungsi upload selesai kita buat, sekarang kita bisa menambahkan fungsi upload image kategori dan hapus image kategori.

# Tambah function upload dan hapus image

Pertama-tama buka file KategoriController.php dan di dalam class KategoriController tambahkan 2 function di bawah function destroy.

    public function uploadimage(Request $request) {
        $this->validate($request, [
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
            'kategori_id' => 'required',
        ]);
        $itemuser = $request->user();
        $itemkategori = Kategori::where('user_id', $itemuser->id)
                                ->where('id', $request->kategori_id)
                                ->first();
        if ($itemkategori) {
            $fileupload = $request->file('image');
            $folder = 'assets/images';
            $itemgambar = (new ImageController)->upload($fileupload, $itemuser, $folder);
            $inputan['foto'] = $itemgambar->url;//ambil url file yang barusan diupload
            $itemkategori->update($inputan);
            return back()->with('success', 'Image berhasil diupload');
        } else {
            return back()->with('error', 'Kategori tidak ditemukan');
        }
    }

    public function deleteimage(Request $request, $id) {
        $itemuser = $request->user();
        $itemkategori = Kategori::where('user_id', $itemuser->id)
                                ->where('id', $id)
                                ->first();
        if ($itemkategori) {
            // kita cari dulu database berdasarkan url gambar
            $itemgambar = \App\Image::where('url', $itemkategori->foto)->first();
            // hapus imagenya
            if ($itemgambar) {
                \Storage::delete($itemgambar->url);
                $itemgambar->delete();
            }
            // baru update foto kategori
            $itemkategori->update(['foto' => null]);
            return back()->with('success', 'Data berhasil dihapus');
        } else {
            return back()->with('error', 'Data tidak ditemukan');
        }
    }

# web route

Buka file web.php di folder routes dan tambahkan 2 buah route upload dan delete image.

<?php

/*

|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', '[email protected]');
Route::get('/about', '[email protected]');
Route::get('/kontak', '[email protected]');
Route::get('/kategori', '[email protected]');
Route::get('/kategori/{slug}', '[email protected]');
Route::get('/produk', '[email protected]');
Route::get('/produk/{slug}', '[email protected]');

Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function() {
  Route::get('/', '[email protected]');
  // route kategori
  Route::resource('kategori', 'KategoriController');
  // route produk
  Route::resource('produk', 'ProdukController');
  // route customer
  Route::resource('customer', 'CustomerController');
  // route transaksi
  Route::resource('transaksi', 'TransaksiController');
  // profil
  Route::get('profil', '[email protected]');
  // setting profil
  Route::get('setting', '[email protected]');
  // form laporan
  Route::get('laporan', '[email protected]');
  // proses laporan
  Route::get('proseslaporan', '[email protected]');
  // image
  Route::get('image', '[email protected]');
  // simpan image
  Route::post('image', '[email protected]');
  // hapus image by id
  Route::delete('image/{id}', '[email protected]');
  // upload image kategori
  Route::post('imagekategori', '[email protected]');
  // hapus image kategori
  Route::delete('imagekategori/{id}', '[email protected]');
});

Auth::routes();

Route::get('/home', '[email protected]')->name('home');

# Update file index.blade.php

Terakhir buka file index.blade.php di dalam folder kategori, dan ubah bagian image kategori menjadi seperti berikut.

@extends('layouts.dashboard')
@section('content')
<div class="container-fluid">
  <!-- table kategori -->
  <div class="row">

Hasil jadinya akan seperti ini ketika salah satu kategori di upload gambarnya.

Sekarang coba buat kategori baru dan upload gambar kategorinya.
