Invalid argument supplied for foreach() – laravel @foreach

June 12, 2022

I’m trying to display product images in a Bootstrap carousel on index view (each product has many images).
PS: I already did the same thing in a previous project and it worked fine. But in this project, I don’t know why it didn’t work.

Here is the index() method that returns all products with their images:

public function index()
{
    $salles = Salle::all();
    return view('index', compact('salles'));
}

Here is the part of the index view that I’m trying to display images on:

@forelse ($salles as $salle)
  <div class="col-lg-4 mb-5 mb-lg-0 p-4 text-center box-container" data-aos="fade-up" data- aos-duration="1000">
     <div class="card">
         <div id="carouselExampleControls{{ $salle->id }}" class="carousel slide" data-bs-ride="carousel">
            <div class="carousel-inner">
               @foreach ($salle->images as $index => $image)
                   <div class="carousel-item {{ $index == 0 ?'active' : '' }}" style="height: 200px">
                        <img src="{{ asset('/storage/images/uploads/'.$image) }}" class="d-block w-100" alt="{{ $image }}" style="object-fit: cover">
                   </div>
               @endforeach

>Solution :

It is possible same sales still does not have image. So use this code

@forelse ($salles as $salle)
@if(empty($salle->images))
    @continue
@endif
<div class="col-lg-4 mb-5 mb-lg-0 p-4 text-center box-container" data-aos="fade-up" data- aos-duration="1000">
    <div class="card">
        <div id="carouselExampleControls{{ $salle->id }}" class="carousel slide" data-bs-ride="carousel">
            <div class="carousel-inner">
                @foreach ($salle->images as $index => $image)
                    <div class="carousel-item {{ $index == 0 ?'active' : '' }}" style="height: 200px">
                        <img src="{{ asset('/storage/images/uploads/'.$image) }}" class="d-block w-100" alt="{{ $image }}" style="object-fit: cover">
                    </div>
                @endforeach
