Laravel 5 Undefined variable Controller 2 View

Question

Im Going crazy with the undefined variable error in laravel , Hope someone could point out what im doing wrong, already tried several ways to pass variable from my controller to my view but nothings seems to work. Thanks in advance

Controller:

   public function busquedaGet()
{
   return view('frontend.user.busquedaBoxeadores',compact('posts'));

}




public function busquedaPost(Request $request, BusquedaRepository $userRepo)

{
     $validator = Validator::make($request->all(), [
        'gender' => 'required|not_in:null',
        'weight' => 'required|not_in:null',
        'country' => 'required|not_in:null'
    ]);


    if ($validator->fails()) {
        return redirect(route('busquedaPostA'))->withErrors($validator);
    }

     $posts=$userRepo->busquedaBoxers($request->all());
      //dd($posts);
    return view('frontend.user.busquedaBoxeadores',compact('posts'));

}

view:

@extends('frontend.layouts.app')

Answer 1

You're trying to display the posts as string in the blade, but it's not defined in busquedaGet and in busquedaPost it's a collection.

Hello, {{ $posts }}

First you need to define a default value for it in busquedaGet and then try to loop through the collection to display it's content.

Answer 2

You are using same view for both methods: busquedaGet and busquedaPost but in busquedaGet you're compact-ing variable posts that is not defined. So you can add empty string if you're not using them in get-method:

public function busquedaGet()
{
    $posts = [];
    return view('frontend.user.busquedaBoxeadores',compact('posts'));
}

And modify view. Replace:

<p> Hello, {{ $posts }} </p>

With:

<p> Hello,
@foreach($posts as $post)
    {{ $post->username }}
@endforeach
</p>
