Undefined variable: foods - laravel

Question

hi guys am in need of assistance , i know this seems to be an easy one but am a bit confused , i have a foreach loop in my main.blade.php file, which shows foods from my database it works fine but when its clicked it meant to lead to the individual post and thats where i get the error
Undefined variable: foods
heres my foreach loop in main.blade.php file
#foreach($foods as $food)
<li class="item">
<a href="{{ route('Foods.show', $food->id) }}">
<img src="{{ Storage::disk('local')->url('food_images/'.$food->image ) }}" class="img-responsive w-25 p-3" alt="Food" >
<div class="menu-desc text-center">
<span>
<h3> {{ $food->title }}</h3>
{{ $food->body }}
</span>
</div>
</a>
<h2 class="white"> #{{ $food->price }}</h2>
</li>
#endforeach
heres my main.blade.php controller
public function LoadHome()
{
$foods = Food::all();
$foods = Food::orderBy('created_at','desc')->inRandomOrder()
->limit(12)
->get();
return view('pages.home')->withFood($foods);
}
and heres Foods.show controller function
public function show($id)
{
$foods = Food::Find($id);
return view('foods.show')->withFood($foods);
}
please what am i doing wrong

Answer 1

Have you tried passing data from your controller to the view using this something like this:
public function show($id)
{
$foods = Food::Find($id);
return view('foods.show')->with('foods', $foods);
}
or, if you're passing multiple variables to the view:
public function show($id)
{
$foods = Food::Find($id);
$something = "else";
return view('foods.show', compact('foods', 'something'));
}
Your view doesn't know what $foods is at that point, so it's always good practice to check that foods is set before the loop:
#if (isset($foods) && $foods->count() > 0)
#foreach($foods as $food)
...
#endforeach
#endif
See the official Laravel docs for more information.

Answer 2

If you want the variable to be named foods in the view then you would need to use withFoods not withFood:
return view(...)->withFoods($foods);
As mentioned in the other answers, there are other ways to pass data to the views as well.

Answer 3

There is no data being passed to a view.
This is how you pass data to a view:
public function LoadHome()
{
$foods = Food::orderBy('created_at','desc')->inRandomOrder()
->limit(12)
->get();
return view('pages.home', ['foods' => $foods])
}
If you always want to have $foods in main.blade.php you should place this in a service provider
View::share('foods', Food::orderBy('created_at','desc')->inRandomOrder()
->limit(12)
->get());
