ErrorException Undefined variable: posts - $posts is undefined

Question

i am receiving an error when clicking on the post link in admin area. Error message says that the problem is in the line of code where

@foreach($posts as $post)

Not sure what the problem is.

index.blade.php

@extends('layouts.app')

@section('content')


            <div class="d-flex justify-content-left">

                <a href="{{ route('posts.create')}}" class="btn btn-success float-right">Add post</a>

                </div>

                <div class="card card-default">
                    <div class="card-header">Posts</div>

                    <div class="card-body">

                                    <tr>

Does this answer your question? ["Notice: Undefined variable", "Notice: Undefined index", and "Notice: Undefined offset" using PHP](https://stackoverflow.com/questions/4261133/notice-undefined-variable-notice-undefined-index-and-notice-undefined) — Pavel Janicek, Dec 14 '20 at 12:19
@PavelJanicek not really relevant here as the problem seems to be with the passing of a variable from a controller to a blade template — Matt, Dec 14 '20 at 12:21

You should bring the variable too, your code should be like this :

$posts = Post::all();

return view ('posts.index', compact('posts'));
