我使用的是从RealRashid甜蜜警报，我需要当用户创建一个类别，它重定向到索引页面和警报成功消息他
存储函数

public function store(Request $request)
{
    $imageUploaded = false;
    $validator = Validator::make($request->all(), [
        'title' => 'required|string|max:100',
        'title_ar' => 'required|string|max:100',
        'img' => 'required|image|mimes:jpeg,png,jpg',
    ]);
    if ($validator->fails()) {
        $errors = $validator->errors();
        return redirect(route('categories.create'))->withErrorMessage($errors);
    }
    if ($request->has('img')) {
        $img = $request->file('img');
        $ext = $img->getClientOriginalExtension();
        $img_name = 'category-' . uniqid() . ".$ext";
        $stored = $img->move(public_path('uploads/categories/'), $img_name);
        if ($stored) {
            $imageUploaded = true;
        } else {
            return redirect(route('categories.create'))->withUploadErrorMessage('Error Uploading Image');
        }
    }
    $title = $request->title;
    $title_ar = $request->title_ar;
    if ($imageUploaded) {
        Category::create([
            'title' => $title,
            'title_ar' => $title_ar,
            'img' => $img_name
        ]);
    }
    return redirect()->route('categories')
        ->withSuccessMessage('Category Created Successfully');
}

在索引页中，我检查成功消息并像这样提醒它

public function index()
{
    if (session('success_message')) {
        Alert::success('Success!', session('success_message'));
    }
    if (session('error_message')) {
        $errors_arr = [];
        foreach (session('error_message')->messages() as $error) {
            array_push($errors_arr, $error[0]);
        }
        $errors_html = collect($errors_arr)->implode('<br>');
        Alert::html('Error', $errors_html, 'error');
    }
    $categories = Category::latest()->get();
    return view('dashboard/categories/categories', compact('categories'));
}

我在主布局中导入了甜蜜警报库

@include('sweetalert::alert')

但它把我重定向到了索引页面而没有引起任何警报
这里有什么问题吗？
