无法从公用文件夹laravel打印图像 [英] Trouble printing out image from public folder laravel

问题描述

我想显示我刚刚上传的图像，并且只显示给已上传图像的人.例如，用户表包含jack，Emily和John，因此，如果jack上传文件，图像将直接显示在他的下面，但是我不知道该怎么做?

I want to show the image that I had just uploaded and only show it to those who have uploaded it. For example, user table contain jack, Emily and John, so if jack were to upload a file the image will show directly under him, but I don't know how to do it?

现在是这样的:

控制器:(我如何存储图像)

Controller: (how I store the image)

public function store1(Request $request){

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

   if ($request->hasFile('file')) {
        $image = $request->file('file');
        $name = $image->getClientOriginalName();
        $size = $image->getClientSize();
        $destinationPath = public_path('/images');
        $image->move($destinationPath, $name);

        $userImage = new UserImage;
        $userImage->name = $name;
        $userImage->size = $size;
        //dd($userImage);
        $userImage->save();
}

view.blade.php

view.blade.php

 @foreach ($data as $object)
    <b>Name: </b>{{ $object->name }}<br><br>
@endforeach

我看到人们在他们的blade.php中使用它，但是我不知道$ model是什么:

I saw people using this inside their blade.php, but I don't know what the $model is:

    <img src="{{ asset('public/images/' . $model->image) }}"> 

Upload.blade.php(这是我的上传页面，用户将在其中上传其图像)

Upload.blade.php (this is my upload page where user will upload their image)

                        {{  csrf_field()  }}


<div class="form-group">
    <label for="imageInput" class="control-label col-sm-3">Upload Image</label>
            <div class="col-sm-9">
                <input type="file" name="file">

        </div>
    </div>

 <div class="form-group">
            <div class="col-md-6-offset-2">
              <input type="submit" class="btn btn-primary" value="Save">
            </div>
          </div>
          </form>

推荐答案

有很多方法可以做到这一点.

There are many ways to do it.

您可以使用Laravel的Eloquent或query builder.

You could either use Eloquent or using query builder of Laravel.

在您的控制器中，您应该获得用户上传的所有图像.

In your controller you should get all the images that the user uploaded.

Query builder方法:

//don't forget the namespace
`use DB;`

//in your function write this.
$images = DB::table('user_images')
        ->join('users', 'users.id', '=', 'user_images.user_id')
        ->where('users.id', '=', $id) 
        ->get();

//use dd($images) to verify that the variable $images has data

//send $images in your view

在您看来，编写如下的foreach循环:

in your view write a foreach loop like so:

@foreach($images as $image)
    <img src="{{ asset('public/images/' . $image->name ) }}"> 
@endforeach
