Laravel nested foreach by using multiple objects

Question

I want to use some data in profile page that I successfully can pass those data to the view

    return view('pages.profile' , compact('data' , 'faculty' , 'scores' , 'sub' , 'finance_r'));

But when I want to use nested for each to print "sub" data in to the foreach base on the "data" section I got an error

Trying to get property 'id' of non-object (View:

The simplest thing that I want to do

@foreach ($data as $data)
  @foreach ($sub as $sub)
    {{ $sub->id }}
  @endforeach
@endforeach

I find this on the laravel Docs but it doesn't work

    @foreach ($users as $user)
    @foreach ($user->posts as $post)
        @if ($loop->parent->first)
            This is first iteration of the parent loop.
        @endif
    @endforeach
@endforeach

How we can able to use a foreach in side the other foreach?

NOTE : all data that I pass to view are Object. My sub data is

Collection {#865 ▼
  #items: array:8 [▼
    0 => Subject {#856 ▼
      #table: "subject"
      +timestamps: false
      #connection: "mysql"
      #primaryKey: "id"
      #keyType: "int"
      +incrementing: true
      #with: []
      #withCount: []
      #perPage: 15
      +exists: true
      +wasRecentlyCreated: false
      #attributes: array:5 [▼
        "id" => 8
        "name" => "پروگرامینگ"
        "number_of_credites" => 5
        "semester_id" => 1
        "faculty_id" => 2
      ]
      #original: array:5 [▶]
      #changes: []
      #casts: []
      #dates: []
      #dateFormat: null
      #appends: []
      #dispatchesEvents: []
      #observables: []
      #relations: []
      #touches: []
      #hidden: []
      #visible: []
      #fillable: []
      #guarded: array:1 [▶]
    }
    1 => Subject {#857 ▶}
    2 => Subject {#858 ▶}

And my data

    Collection {#848 ▼
  #items: array:3 [▼
    0 => Scores {#844 ▼
      #table: "scores"
      +timestampes: false
      #connection: "mysql"
      #primaryKey: "id"
      #keyType: "int"
      +incrementing: true
      #with: []
      #withCount: []
      #perPage: 15
      +exists: true
      +wasRecentlyCreated: false
      #attributes: array:6 [▼
        "id" => 4
        "subject_id" => 15
        "score" => 100
        "scores_student_details_id" => 7
        "created_at" => "2018-04-09 15:02:24"
        "updated_at" => "2018-04-09 15:02:21"

I actually want to print sub according to the "faculty_id" => 1

You are using $users for foreach. Have you send it to view from controller? — Hiren Gohel

Where are you getting the $loop variable from? Are you sure this is where you're throwing your error? Within your code you provided you don't seem to be attempting to access an id property anywhere. — domdambrogia

@Nasser Ali Karimi for which object you need to do nested foreach? — Chirag Patel

Your problem is you are giving the same name in foreach loop.

You can do as per your code by doing this,

@foreach ($data as $value)
  @foreach ($sub as $subValue)
    {{ $subValue->id }}
  @endforeach
@endforeach

But this is not good practice,

Based on my opinion, you have to change your variable's name in your controller, like you can pass datas instead of data, subs instead of sub,

 return view('pages.profile' , compact('datas' , 'faculty' , 'scores' , 'subs' , 'finance_r'));

And then you can do foreach loop,

@foreach ($datas as $data)
      @foreach ($subs as $sub)
        {{ $sub->id }}
      @endforeach
@endforeach

Always give your variable names relevant to your variable's work (singular/plural).

Try this and comment if you have any doubts.
