尝试使用(img src)标签显示图像,图像的路径保存在我的数据库中

我已成功将从用户上传的图像保存到“广告”表中名为“图像”的字段中。但是我在查看(blade.php)文件中显示图像时遇到问题。

我尝试在线搜索解决方案,但没有一个适用于我的解决方案...

以下是我的AdvertisementsController的存储方法:-

public function store(Request $request)
{
    // $media = Media::all();

    request()->validate([
        'image' => 'required',
        'image' => 'image|mimes:jpeg,png,jpg,gif,svg|max:2048'
    ]);

    //find current admin's id
    $admin_user = auth()->id();

    if ($request->hasFile('image')) {
        $image = $request->file('image');
        $image_name = str_slug($request->title).'.'.$image->getClientOriginalExtension();
        $folderPath = public_path('/uploads/images');
        $imagePath = $folderPath. "/".  $image_name;
        $image->move($folderPath, $image_name);
    }

    $title = request('title');
    $description = request('description');
    $sort_num = request('sort_num');

    $media = Media::create([
        'title' => $title,
        'description' => $description,
        'sort' => $sort_num,
        'created_by' => $admin_user,
    ]);

    Advertisement::create([
        'image' => $imagePath,
        'expired_at' => Carbon::now()->format('Y-m-d H:i:s'),
        'media_id' => $media->id,
    ]);

    // return back()->with('success', 'Your advertisement has been successfully created!');
    return redirect('/advertisements');

}

我可以成功保存路径,但是保存的路径很长,例如:“ / Users / hannzern / Desktop / numericledger-backend / public / uploads / images / klang-river.jpeg”,并认为该路径将保存为“ /public/uploads/images/klang-river.jpeg”。这可能是问题吗?

以下是我的视图(blade.php)的代码:-

<h1>Advertisements</h1>

<ul>
    @foreach ($advertisements as $advertisement)
        <a href="/advertisements/{{$advertisement->id}}">
            {{ $advertisement->media->title }}   
        </a>
        <br>

        //Three methods of retrieving the image from the path but all three not working
        <img src="{{ $advertisement->image }}" height="300" width="200">

        <img src="/Users/hannzern/Desktop/numericledger-backend/public/uploads/images/klang-river.jpeg" height="300" width="200">

        <img src="/public/uploads/images/klang-river.jpeg" height="300" width="200">

        <br>
        <br>
        <br>
        <br>
    @endforeach

</ul>

<a href="/advertisements/create">Add new advertisement</a>

另外,从文件目录中,我可以在/ public / uploads / images文件夹中看到“ klang-river.jpeg”图像。有人知道为什么吗? :(

答案 0 :(得分:2)

/public将通过在浏览器的链接中使用/来解决,因此您的链接应另存为数据库:

/Users/hannzern/Desktop/numericledger-backend/uploads/images/klang-river.jpeg

但是,要确保在托管应用程序的任何地方都可以使用此方法,则不应保存绝对路径。只将以下内容保存到数据库中:

klang-river.jpeg

然后,使用asset()帮助器,可以在模板中调用正确的网址:

<img src="{{ asset('uploads/images/' . $advertisement->image) }}" height="300" width="200">

这将解析为预期的URL。我希望这会有所帮助。
