How to get variable in Laravel blade @foreach loop from outer view

Question

I have blade view with @foreach loop. In this blade view I also pass on $user variable in UserController. Inside @foreach I have code {{ $user->getAvatar() }}.

@extends('layouts.app')

@section('content')

@foreach($threads as $thread)
    <div class="media alert {{ $class }}">
        <img src="{{ $user->getAvatar() }}">
        <div class="media-body">
            <p>
            {{ $thread->latestMessage->body }}
            </p>
        </div>    
    </div>
@endforeach

@endsection

This is index() function in my controller

public function index()
    {
        $user = Auth::user();
        $threads = Thread::getAllLatest()->get();
        return view('messenger.index', compact('threads', 'user'));
    }

I have error Undefined variable: user. foreach loop don't see variable from other part of view.

ErrorException (E_ERROR)
Undefined variable: user (View:messenger\partials\thread.blade.php) (View: messenger\partials\thread.blade.php)
Previous exceptions
Undefined variable: user (View: messenger\partials\thread.blade.php) (0)
Undefined variable: user (0)

You're calling the view messenger.index but the error is coming from messenger\partials\thread.blade.php. Are you showing us all the relevant view code? Are you calling a partial somewhere and not passing that variable to it? — waterloomatt

In your case, please use this code on return

return View::make('messenger.index')

->with(compact('threads'))

->with(compact('user'));

You can use with as many time as you want. This will resolve your issue hopefully.

You need to check if variable has value or not, if laravel failed to get value of $user->getAvatar() it will definitely return error so just try following

@isset($user->getAvatar())

@endisset

Try with this:

@foreach($threads as $thread)
    <div class="media alert {{ $class }}">
        <img src="{{ isset($user) ? $user->getAvatar : '' }}">
        <div class="media-body">
            <p>
            {{ $thread->latestMessage->body }}
            </p>
        </div>    
    </div>
@endforeach

Try defining it above foreach loop

@extends('layouts.app')

@section('content')
<?php 
   $user_avatar = $user->getAvatar();
?>
@foreach($threads as $thread)
<div class="media alert {{ $class }}">
    <img src="{{ $user_avatar }}">
    <div class="media-body">
        <p>
        {{ $thread->latestMessage->body }}
        </p>
    </div>    
</div>
@endforeach

@endsection

Hope it Helps !

Undefined variable: user_avatar.

Why you don't use auth() helper function instead

<img src="{{ auth()->user()->getAvatar() }}">

This way you don't need to pass it trough the controller.
