在拉拉维尔，我无法检索上传的图像。我创建了存储链接。但我不会work.Did错过什么吗？

Question

图像显示为“图像描述”。如何检索数据库中的图像？除了图像之外，所有的工作都很顺利。

这是我的第一个项目。我找不到这个问题。有人能帮忙解决这个问题吗？

这是我的index.blade.php

<ul class="list-group list-group-horizontal-sm position-relative z-index-2 flex-row overflow-auto overflow-md-visble">
    @foreach($products as $p)
    <li class="list-group-item py-2 px-3 px-xl-4 px-wd-5 flex-horizontal-center shadow-on-hover-1 rounded-0 border-top-0 border-bottom-0 flex-shrink-0 flex-md-shrink-1">

        <a href="../shop/product-categories-7-column-full-width.html" class="d-block py-2 text-center">
            <img class="img-fluid mb-1 max-width-100-sm" src="/storage/admin/{{ $p ['prod_image_path'] }}" alt="Image Description">
            <h6 class="font-size-14 mb-0 atext font-weight-semi-bold">{{ $p ['prod_name'] }}</h6>
            <h6 class="font-size-14 mb-0 atext font-weight-semi-bold">{{ $p ['prod_price'] }}</h6>
        </a>
    </li>

    <li class="list-group-item py-2 px-3 px-xl-4 px-wd-5 flex-horizontal-center shadow-on-hover-1 rounded-0 border-top-0 border-bottom-0 flex-shrink-0 flex-md-shrink-1">
        <a href="../shop/product-categories-7-column-full-width.html" class="d-block py-2 text-center">
            <img class="img-fluid mb-1 max-width-100-sm" src="/storage/admin/{{ $p ['prod_image_path'] }}" alt="Image Description">
            <h6 class="font-size-14 mb-0 atext font-weight-semi-bold">{{ $p ['prod_name'] }}</h6>
            <h6 class="font-size-14 mb-0 atext font-weight-semi-bold">{{ $p ['prod_price'] }}</h6>
        </a>
    </li>
    @endforeach
</ul>

这是我的ProductsController。

    <?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Product;
use App\Category;

class ProductsController extends Controller
{
    public function __construct()
    {
        $this->middleware('auth');
    }

         
    public function index()
    {
        $arr['products'] = Product::all();
        return view('admin.products.index')->with($arr);
    }

   

   
    public function create()
    {
        return view('admin.products.create');
    }

  
    public function store(Request $request, Product $product, Category $category)
    {

        if($request->prod_image_path->getClientOriginalName())
        {
            $ext =$request->prod_image_path->getClientOriginalName();
            $file = date('YmdHis').rand(1,99999).'.'.$ext;
            $request->prod_image_path->storeAs('public/admin',$file);
        }else{
            $file ='';
        }

        $product-> prod_name = $request-> prod_name;
        $product-> prod_meta_title = $request-> prod_meta_title;
        $product-> prod_description = $request-> prod_description;
        $product-> prod_category = $request-> prod_category;
        $product-> prod_price = $request-> prod_price;
        $product-> prod_discount = $request-> prod_discount;
        $product-> prod_image_path = $file; 
       
        $product->save();
        return redirect()->route('admin.products.index');
       
    }

  
    public function show($id)
    {
       $product = Product::find($id);
       return view ('user.show',['product'=>$product]);
    }
  

    public function edit(Product $product)
    {
        $arr['product'] = $product;
        return view('admin.products.edit')->with($arr);

    }

   
    public function update(Request $request, Product $product)
    {
        if($request->prod_image_path->getClientOriginalName())
        {
            $ext =$request->prod_image_path->getClientOriginalName();
            $file = date('YmdHis').rand(1,99999).'.'.$ext;
            $request->prod_image_path->storeAs('public/admin',$file);
        }else{
            $file ='';
        }
        $product-> prod_name = $request-> prod_name;
        $product-> prod_meta_title = $request-> prod_meta_title;
        $product-> prod_description = $request-> prod_description;
        $product-> prod_category = $request-> prod_category;
        $product-> prod_price = $request-> prod_price;
        $product-> prod_discount = $request-> prod_discount;
        $product-> prod_image_path = $file;
        $product->save();
        return redirect()->route('admin.products.index');
    }

    
    public function destroy($id)
    {
       Product:: destroy($id);
       return redirect()->route('admin.products.index');
    }
}

我的图像路径如下所示。

Answer 1

最好的方法是使用Model类上的setter方法获得图像，该类返回完整路径或空(如果没有图像)

Product.php

<?php
use Storage;
class Product extends Model
{
    // .. other information.
    public function getProdImagePathAttribute(){
        return $this->attributes['prod_image_path'] ? Storage::url('admin/'.$this->attributes['prod_image_path']) : null;
    }
}

products.blade.php

@if($p['prod_image_path'])
  <img class="img-fluid mb-1 max-width-100-sm" src="{{URL::asset($p['prod_image_path'])}}"" alt="Image Description">

@else
  <img src="{{URL::asset('admin/default-product.jpg')}}" alt="default-pic">
@endif
