Intervention \ Image \ Exception \ ImageNotWritableException using Laravel 4
提问by Stephen Tafler
I am using Laravel 4. I am not sure why I am getting this error when everything seems to be correct. Also, the product is not updating to the database.
我正在使用 Laravel 4。当一切似乎都正确时，我不确定为什么会出现此错误。此外，该产品不会更新到数据库。

Make sure the public/img/productsfolder exists and it's writable and also try to use absolute path if necessary, like this:
确保该public/img/products文件夹存在且可写，并在必要时尝试使用绝对路径，如下所示：
$filename = time() . '.' . $image->getClientOriginalExtension();
$path = public_path('img/products/' . $filename);
Image::make($image->getRealPath())->resize(468, 249)->save($path);

replace :
代替 ：
Image::make($image->getRealPath())->resize(468, 249)->save('/img/products/'.$filename);
with:
和：
Image::make($image->getRealPath())->resize(468, 249)->save('public/img/products/'.$filename);
you must specify the publicfolder for the savemethod.
您必须public为该save方法指定文件夹。
