Auth::routes(['verify' => true]);

Route::resource('posts', PostController::class);

The crud works very well and we see it very well on another page that I called show, but I would like us to see the posts on the home page too. But I have an error: Undefined variable $post How can I solve this, the posts must be displayed on the home page too

CodePudding user response：

The reason you cannot see $post in your home.blade.php is because you are passing in $posts and you are referencing $post in your blade file. There's nothing wrong with this, but you need to ensure to loop over $posts so that you can assign each post to a $post variable.

Something like:

@foreach ($posts as $post)
     // now you can access your $post variable here...
     <h1> Title: {{ $post->title }} </h1>
@endforeach

I have resolve this question need to add

public function index()
{
    $posts = Post::all();
    return view('home', compact('posts'));
}

In Homecontroller
