LARAVEL-将变量从控制器传递到视图

Question

I want to show my posts on the homepage just under my form. I can already add post to my DB.

Now I just get Undefined variable if I try to use this variable in my view page.

Route =

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

Controller =

public function show()
{
    $posts = Post::orderBy('created_at', 'asc')->get();

    return view('/home', [
        'posts' => $posts
    ]);
}

View

@if (count($posts) > 0)
    <div class="panel panel-default">
        <div class="panel-heading">
            Posts
        </div>

        <div class="panel-body">
            <table class="table table-striped task-table">

                <!-- Table Headings -->
                <thead>
                <th>Posts</th>
                <th>&nbsp;</th>
                </thead>

                <!-- Table Body -->
                <tbody>
                @foreach ($posts as $post)
                    <tr>
                        <!-- Post Name -->
                        <td class="table-text">
                            <div>{{ $post->description }}</div>
                        </td>
                    </tr>
                @endforeach
                </tbody>
            </table>
        </div>
    </div>
@endif

Answer 1

The right way is using Route::resources() only for REST (just my opinion). Try to create a new Route like

Route::get('hello-there', [
    'as' => 'front.index',
    'uses' => 'PostController@index',
]);

Now u can get access to your action by: "wwww.mydomain.com/hell-there Next step - make action named "index" if it is list.

public function index()
{
    return view('home', [
        'posts' => Post::orderBy('created_at', 'asc')->get(),
    ])
}

U need blade view file in below directory named "home.blade.php":

application_path/resources/

Your blade file looks correct. Good luck mate.

Try this

public function show()
{
    $posts = Post::orderBy('created_at', 'asc')->get();

    return view('home', [
        'posts' => $posts
    ]);
}

and show us your blade view, what the path and name?

Answer 3

you could try to use:

return view('/home', compact('posts));

this works for me.
