图片未在浏览器 laravel 上显示

Question

我正在处理我的项目，我必须在我的数据库中上传一张图片，一切正常，图片正在上传到我给定的路径，但它没有显示在浏览器上，这是我的代码，有人可以告诉我错误是什么我正在做。

这是我的控制器文件

  public function store(Request $request){

        $this->validate($request,[
            'image' =>'required|image|mimes:jpeg,png,jpg|max:4000',
        ]);

        $news = new News();


        if($request->hasFile($request->input('image'))){
            $file = $request->file('image');
            $extension = $file->getClientOriginalExtension();
            $filename = time().'.'.$extension;
            $file->move('assets_info/uploads/news/',$filename);
            $news->image = $filename;
        }

        $news->save();

        return redirect()->route('news.index')->with('success','News Added Successfully');


    }

这是我的查看文件

Answer 1

你确定你的文件正在上传吗？ 根据您的控制器代码

$request->hasFile()

提供了错误的参数。该参数应该是文件字段的名称，而不是正在上传的文件。 将其更改为

$request->hasFile('image')

看这里： https://laraveldaily.com/requests-has-and-hasfile/

Answer 2

首先改变你的控制器

$file->move('assets_info/uploads/news/',$filename);

至

$file->move(public_path('uploads/news/'), $filename);

这是您的控制器的完整源代码，您应该像这样更新您的控制器，

public function store(Request $request){

    $this->validate($request,[
        'image' =>'required|image|mimes:jpeg,png,jpg|max:4000',
    ]);

    $news = new News();

    if ($request->file('image')) {
        $file = $request->file('image');
        $filename = date('YmdHi').$file->getClientOriginalName();

        $file->move(public_path('uploads/news/'), $filename);

        $news->image = $filename;
    }

    $news->save();

    return redirect()->route('news.index')->with('success','News Added Successfully');
}

然后更新您的视图文件

<img src="{{asset('assets_info/uploads/news/',$news->image)}}" class="img-fluid"> 

至

<img src="{{url('uploads/news/'.$news->image)}}" class="img-fluid">

这是您更新的视图文件的完整源代码，

<section class="news-section mt-5">
  <div class="container-fluid">
    <div class="row">
      <div class="col-md-9">
          <section class="">
            <div class="row">
              <div class="col-md-12">
                @foreach ( $allnewsObj as $news)
                <?php
                  $newsTitle = ($locale === 'en')? $news->title_english:$news->title_arabic;
                  $newsContent = ($locale === 'en')? $news->content_english:$news->content_arabic;
                ?>
                <a href="{{route('news_details',$news->id)}}">
                  <div class="right-news right-news2 bg-greyish my-3">

                    <img src="{{utl('uploads/news/'.$news->image)}}" class="img-fluid">

                    <div class="content-news">
                      <h4>{{$newsTitle}}</h4>
                      <p><?php echo $newsContent; ?></p>
                    </div>
                  </div>
                </a>
    
                @endforeach
              </div>
            </div>
            <h4 class="bg-greyish p-2  mb-5 text-end h4-news">
            <a href="#" class="">More</a>
          </h4>
          </section>
      </div>

      <div class="col-md-3">
        <div class="">
          <h4>Trending News</h4>
          @foreach ( $trendingNewsObj as $item )
          <ul class="ul-news">
            <li><a href="{{route('news_details',$item->id)}}">{{$item->title_english}}</a></li>
          </ul>        
          @endforeach
        </div>
      </div>
    </div>
