在laravel 8中使用select选项的旧多选数组

public function handleFormSubmit(Request $request)
{
    $selectedOptions = $request->input('options');

    // 处理选中的选项
    // ...

    return redirect()->back()->with('success', '选项已处理');
}

<form action="{{ route('form.submit') }}" method="POST">
    @csrf

    <select name="options[]" multiple>
        <option value="option1">选项1</option>
        <option value="option2">选项2</option>
        <option value="option3">选项3</option>
    </select>

    <button type="submit">提交</button>
</form>

use App\Http\Controllers\FormController;

Route::post('/form/submit', [FormController::class, 'handleFormSubmit'])->name('form.submit');
