Laravel 用数组填充选择选项

Question

I keep getting error

Invalid argument supplied for foreach()

when trying to populate select options with the array I've made in Laravel controller. Below is my code. Thanks

Controller :

public function index()
{
    $select_options = array(
        array(
            'name' => 'ALL',
            'value' => 'all',
        ),
        array(
            'name' => 'Option 1',
            'value' => 'option_2',
        ),
        array(
            'name' => 'Option 2',
            'value' => 'option_2',
        ),
    );
    
    return view('home', [
        'select_options' => $select_options,
    ]);
}

HTML :

@php
    $old_business_unit= old('old_select_options', $filters['select_options'] ?? null);
@endphp
<select class="form-control custom-select @error('select_options')is-invalid @enderror" name="select_options">
    <option value="">-</option>
    @foreach ($select_options as $select_option)
        @if ($select_option->value == $old_select_options)
            <option value="{{ $select_option->value }}" selected>{{ $select_option->name }}</option>
        @else
            <option value="{{ $select_option->value }}">{{ $select_option->name }}</option>
        @endif
    @endforeach
</select>
@error('select_options')
    <div class="invalid-feedback">
        {{ $message }}
    </div>

$select_option is an array, not an object. $select_option->value won't work. It will most likely throw the error : " Trying to access property 'value' of non-object. "

The correct notation to access the 'value' key of the $select_option array is $select_option['value'] .

@foreach ($select_options as $select_option)
    @if ($select_option['value'] == $old_select_options)
        <option value="{{ $select_option['value'] }}" selected>{{ $select_option['name'] }}</option>
    @else
        <option value="{{ $select_option['value'] }}">{{ $select_option['name'] }}</option>
    @endif
@endforeach
