Unknown error when uploading file using laravel
提问by vonc
When I try to upload an image file to the server, randomly it gives error and sometimes it works fine with no problems with the same file.
当我尝试将图像文件上传到服务器时，它会随机出现错误，有时它可以正常工作，同一个文件没有问题。
Symfony \ Component \ HttpFoundation \ File \ Exception \ FileException
The file "xxxxxx.jpg" was not uploaded due to an unknown error.
This is my code:
这是我的代码：
if (Input::hasFile('thumbnail_image')){
// Upload Photo
$thumbnailImage = Input::file('thumbnail_image');
$filename = 'thumbnail.'.Input::file('thumbnail_image')->getClientOriginalExtension();
$destinationPath = 'training_product/article_id_'. $id .'/thumbnail_image';
$databasePath = '/adidas/public/training_product/article_id_'. $id.'/thumbnail_image';
$uploadFile = Input::file('thumbnail_image')->move($destinationPath, $filename);
$product->thumbnail_images_path = $databasePath.'/'.$filename;
$product->save();
}

What are your file permission on your destination folder? Try changing it to 777(assuming that you are using a linux server: sudo chmod -R 777 adidas/public/training_product.
您对目标文件夹的文件权限是多少？尝试将其更改为777（假设您使用的是 linux 服务器：sudo chmod -R 777 adidas/public/training_product.
I've modified your code slightly and it works for me.
我稍微修改了你的代码，它对我有用。
```
``
if (Input::hasFile('thumbnail_image')){
// Upload Photo
$product = new Product;
$thumbnailImage = Input::file('thumbnail_image');
$ext = $thumbnailImage->guessExtension();
$filename = 'thumbnail_'. time() . $ext;
$destinationPath = 'training_product/article_id_'. $id .'/thumbnail_image';
$databasePath = '/adidas/public/training_product/article_id_'. $id.'/thumbnail_image/';
$thumbnailImage->move($destinationPath, $filename);
$product->thumbnail_images_path = $databasePath . $filename;
$product->save();
}
```

I've Changed getClientOriginalExtension()to guessExtension(), instantiated a new $product, as I didn't see you doing. Also made sure the folder permissions would allow me to upload files.
我已更改getClientOriginalExtension()为guessExtension()，实例化了一个新的$product，因为我没有看到您在做什么。还确保文件夹权限允许我上传文件。
Hope it helps.
希望能帮助到你。
