刀片中的过滤阵列

Question

I need to show a certain picture. If a picture has is_primary property filled and true then I need to show that picture. Otherwise, I should just display whatever is first. Here is my code. It doesn't work, I see both is_primary picture and first. What am I doing wrong?

@php
  $check = 0
@endphp
@foreach ($ad->photos as $photo)
  @if ($photo->is_primary == true)
    <img src="{{$photo->filename}}" alt="{{$ad->name}}" class="card-image">
    @php
      $check = 1
    @endphp
  @endif
@endforeach

@if ($check > 0)
  <img src="{{$ad->photos->first()->filename}}" alt="{{$ad->name}}" class="card-image">
@endif

You have issue in you logic. If is_primary is true you are displaying image and set flag variable to 1 . And end of loop you are checking $check > 0 so its true when $check =1 you need to add condition $check == 0

@php
  $check = 0
@endphp
@foreach ($ad->photos as $photo)
  @if ($photo->is_primary == true)
    <img src="{{$photo->filename}}" alt="{{$ad->name}}" class="card-image">
    @php
      $check = 1
    @endphp
  @endif
@endforeach

@if ($check == 0)
  <img src="{{$ad->photos->first()->filename}}" alt="{{$ad->name}}" class="card-image">
@endif

OR you can check != 1

@if ($check != 1)
      <img src="{{$ad->photos->first()->filename}}" alt="{{$ad->name}}" class="card-image">
    @endif
