如何在 laravel 中更新多个图像

Question

我想更新 laravel 上的多张图片，更新后旧的图片会自动从存储中删除。

我尝试使用下面的更新方法来实现它：

public function update(Request $request, $id)
{

    $listing = Listing::where('id', $id)->first();
    
    $listing->title = $request->get('title');
    $listing->price = $request->get('price');
    $listing->address = $request->get('address');
    $listing->rooms = $request->get('rooms');
    $listing->city = $request->get('city');
    $listing->state = $request->get('state');
    $listing->zip_code = $request->get('zip_code');
    $listing->area = $request->get('area');
    $listing->balcony = $request->get('balcony');
    $listing->bedrooms = $request->get('bedrooms');
    $listing->bathrooms = $request->get('bathrooms');
    $listing->toilet = $request->get('toilet');
    $listing->bathroom_type = $request->get('bathroom_type');
    $listing->kitchen = $request->get('kitchen');
    $listing->parking_space = $request->get('parking_space');
    $listing->description = $request->get('description');
    $listing->featured = $request->get('featured');
    $listing->status = $request->get('status');
    $listing->type = $request->get('type');
    $listing->water_supply = $request->get('water_supply');
    $listing->power_supply = $request->get('power_supply');

    if($request->hasFile('images') != ''){    
        
        $listingImage = ListingImage::findOrFail($id);    
        //add new image
        foreach ($request->file('images') as $image) {
            $image = $request->file('images');
            $imageName = time().'.'.$image->getClientOriginalExtension();
    
            $oldImagepath = $listingImage->image_path;
            // Update the database
            $listingImage->image_path = $imageName;
            // Delete the old photo
            Storage::delete($oldImagepath);
            $listingImage->save();
            $image->move(public_path('images/listing/'.$listing->id),$imageName);
        }
    }

    $listing->save();
    return redirect('/home')->with('success', 'Listing updated!');
}

但我得到了错误 错误 调用数组上的成员函数 getClientOriginalExtension()。我的图像存储在 ListingImage 模型中，并且我已将默认文件系统配置为

'local' => [
            'driver' => 'local',
            'root' => public_path('images/listing/'),
        

我可以采取哪些步骤来更新我的 laravel 应用程序中的新图像

Answer 1

在foreach loop 中，您使用的是错误的$request->file('images')，您将其分配给$image 变量，它应该是：

foreach ($request->file('images') as $image) {
         // remove this line of code
         $image = $request->file('images');
        $imageName = time().'.'.$image->getClientOriginalExtension();

        $oldImagepath = $listingImage->image_path;
        // Update the database
        $listingImage->image_path = $imageName;
        // Delete the old photo
        Storage::delete($oldImagepath);
        $listingImage->save();
        $image->move(public_path('images/listing/'.$listing->id),$imageName);
    }

首先你改变$image->getClientOriginalExtension()而不是$image->file('images)->getClientOriginalExtension()。

第二次你保存多张图片在这样的列["first_image.jpeg", "second_image.jpeg"]

$images = [];
foreach ($request->file('images') as $image) {
      $imageName = time().'.'.$image->getClientOriginalExtension();
      //save images in public/images/listing folder
      $image->move(public_path('images/listing/'), $imageName);
      // Delete the old photo
      $oldImagepath = $listingImage->image_path;
      Storage::delete($oldImagepath);
      $images[] = $imageName;
      $json_encode = json_encode($images);
      $listingImage->image_path = $json_encode;
}

$listingImage->save();
