語法錯誤，意外標記“endforeach”，需要“elseif”或“else”或“endif”

Question

所以我做了一個jetstream項目，這是我第一次使用jetstream。 我的問題是，由於某種原因，程序的索引頁說我沒有關閉 foreach 循環，而實際上我已經關閉了。 我很確定它一直在工作，直到我添加了一種在列中存儲數據的方法，然后它就沒有工作了。 存儲功能有問題還是@有問題？

Answer 1

@empty指令需要像其他刀片指令一樣關閉。

<x-app-layout>
    <x-slot name="header">
        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('Program') }}
        </h2>
    </x-slot>

    <div class="py-12">
        <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
          <a href="{{ route('program.create' )}}" class="bg-green-500 hover:bg-green--700 text-white font-bold py-2 px-4 rounded">Tambah Program</a>
          <br/>

          @foreach ($program as $programs)
            <a href="{{ route('program.show', $program->id) }}" class="group block max-w-xs mx-auto rounded-lg p-6 bg-white ring-1 ring-slate-900/5 shadow-lg space-y-3 hover:bg-sky-500 hover:ring-sky-500">

                <h3 class="text-slate-900 group-hover:text-white text-sm font-semibold">{{ $program->year }}</h3>
              </div>
            </a>
          <br/>
          @endforeach

          @empty($program)
            <tr class="bg-white border-b dark:bg-gray-800 dark:border-gray-700">
              <td colspan="2" class="px-6 py-4 font-medium text-gray-900 dark:text-white whitespace-nowrap">
                {{ __('No programs') }}
              </td>
            </tr>
          @endempty
          
        </div>
    </div>
</x-app-layout>

或者，使用forelse ：

<x-app-layout>
    <x-slot name="header">
        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('Program') }}
        </h2>
    </x-slot>

    <div class="py-12">
        <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
          <a href="{{ route('program.create' )}}" class="bg-green-500 hover:bg-green--700 text-white font-bold py-2 px-4 rounded">Tambah Program</a>
          <br/>

          @forelse ($program as $programs)
            <a href="{{ route('program.show', $program->id) }}" class="group block max-w-xs mx-auto rounded-lg p-6 bg-white ring-1 ring-slate-900/5 shadow-lg space-y-3 hover:bg-sky-500 hover:ring-sky-500">
              <div class="flex items-center space-x-3">
                <svg class="h-6 w-6 stroke-sky-500 group-hover:stroke-white" fill="none" viewBox="0 0 24 24"><!-- ... --></svg>
                <h3 class="text-slate-900 group-hover:text-white text-sm font-semibold">{{ $program->year }}</h3>
              </div>
            </a>
          <br/>
          @empty
            <tr class="bg-white border-b dark:bg-gray-800 dark:border-gray-700">
              <td colspan="2" class="px-6 py-4 font-medium text-gray-900 dark:text-white whitespace-nowrap">
                {{ __('No programs') }}
              </td>
            </tr>
          @endforelse
          
        </div>
    </div>
</x-app-layout>

Answer 2

您只需要將@foreach更改為@forelse

@forelse ($users as $user)
    <li>{{ $user->name }}</li>
@empty
    <p>No users</p>
@endforelse

編輯后會像這樣

<x-app-layout>
    <x-slot name="header">
        <h2 class="font-semibold text-xl text-gray-800 leading-tight">
            {{ __('Program') }}
        </h2>
    </x-slot>

    <div class="py-12">
        <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
          <a href="{{ route('program.create' )}}" class="bg-green-500 hover:bg-green--700 text-white font-bold py-2 px-4 rounded">Tambah Program</a>
          <br/>

          @forelse ($program as $programs)
            <a href="{{ route('program.show', $program->id) }}" class="group block max-w-xs mx-auto rounded-lg p-6 bg-white ring-1 ring-slate-900/5 shadow-lg space-y-3 hover:bg-sky-500 hover:ring-sky-500">
              <div class="flex items-center space-x-3">
                <svg class="h-6 w-6 stroke-sky-500 group-hover:stroke-white" fill="none" viewBox="0 0 24 24"><!-- ... --></svg>
                <h3 class="text-slate-900 group-hover:text-white text-sm font-semibold">{{ $program->year }}</h3>
              </div>
            </a>
          <br/>
          @empty
            <tr class="bg-white border-b dark:bg-gray-800 dark:border-gray-700">
              <td colspan="2" class="px-6 py-4 font-medium text-gray-900 dark:text-white whitespace-nowrap">
                {{ __('No programs') }}
              </td>
            </tr>
          @endforelse          
        </div>
    </div>
</x-app-layout>

Answer 3

@foreach ($test as $data)
// do whatever you want 
@if($data=="test")
   $val=1;
@else
  $val=0;
@endif

@endforeach

// If you are opening a directive its must be closed.

Answer 4

我建議這個邏輯

@forelse ($users as $user)
  <li>{{ $user->name }}</li>
@empty
  <p>No users</p>
@endforelse enter code here
