Bagaimana cara menampilkan data by category di laravel livewire
Selamat siang, bagaimana ya cara menampilkan data post by category di laravel livewire ? disini saya ingin mencoba menampilkan data post by category dengan cara seperti di bawah ini namun masih belum berjalan:
web.php
Route::get('category/{category:slug}',[FrontController::class, 'category'])->name('category');
FrontController.php
public $search;
public function category(Category $category)
{
$categories = Category::all();
$general = General::find(1);
$locale = App::currentLocale();
$category_id = $category->id;
$search = request("search");
$posts = Post::where([
['lang',$locale],
['category_id',$category_id],
['status','PUBLISH'],
])->latest()->paginate(12);
if ($this->search !== null) {
$posts = Post::where([
['title','like', '%' . $this->search . '%'],
['lang',$locale],
['category_id',$category_id],
['status','PUBLISH'],
])->latest()->paginate(12);
}
// dd($category_id);
$tags = Tag::all();
$top = Post::where('status','PUBLISH')->orderBy('views','desc')->limit(5)->get();
return view ('front.category',compact('categories','category_id','general','locale','posts','tags','top'));
}

Kalau saya dd($category_id); di FrontController.php muncul id dari kategori tersebut, tapi kalau saya coba dd di livewire\CategoryIndex.php muncul null. gimana ya cara yang benar untuk menampilkan post by category ? terimakasih
2 Jawaban:
<div>Apakah kamu sudah mengoper parameter dari blade file ke component livewirenya?<br><br>//contoh oper variable post ke livewire dari blade</div><pre><livewire:show-post :post="$post"> </pre><div><br>//Contoh menerima variable post di component</div><pre>class ShowPost extends Component { public $title; public $content;
public function mount($post)
{
$this-&gt;title = $post-&gt;title;
$this-&gt;content = $post-&gt;content;
}
...
}</pre>
