Tahapan Implementasi & Walkthrough Kode
Berikut adalah langkah demi langkah teknis yang dapat Anda ikuti langsung pada codebase Anda:
Tahap 1: Penulisan Kode & Konfigurasi
<?php
namespace App\Http\Controllers;
use App\Models\Post;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
class PostController extends Controller
{
/**
* index
*
* @return void
*/
public function index()
{
//get posts
$posts = Post::latest()->paginate(5);
//render view with posts
return view('posts.index', compact('posts'));
}
/**
* create
*
* @return void
*/
public function create()
{
return view('posts.create');
}
/**
* store
*
* @param Request $request
* @return void
*/
public function store(Request $request)
{
//validate form
$this->validate($request, [
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'title' => 'required|min:5',
'content' => 'required|min:10'
]);
//upload image
$image = $request->file('image');
$image->storeAs('public/posts', $image->hashName());
//create post
Post::create([
'image' => $image->hashName(),
'title' => $request->title,
'content' => $request->content
]);
//redirect to index
return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Disimpan!']);
}
/**
* edit
*
* @param mixed $post
* @return void
*/
public function edit(Post $post)
{
return view('posts.edit', compact('post'));
}
/**
* update
*
* @param mixed $request
* @param mixed $post
* @return void
*/
public function update(Request $request, Post $post)
{
//validate form
$this->validate($request, [
'image' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'title' => 'required|min:5',
'content' => 'required|min:10'
]);
//check if image is uploaded
if ($request->hasFile('image')) {
//upload new image
$image = $request->file('image');
$image->storeAs('public/posts', $image->hashName());
//delete old image
Storage::delete('public/posts/'.$post->image);
//update post with new image
$post->update([
'image' => $image->hashName(),
'title' => $request->title,
'content' => $request->content
]);
} else {
//update post without image
$post->update([
'title' => $request->title,
'content' => $request->content
]);
}
//redirect to index
return redirect()->route('posts.index')->with(['success' => 'Data Berhasil Diubah!']);
}
