无法在 Laravel 5 中上传文件

Question

I am trying to upload an image in Laravel 5.

My environment is Windows. I am using php artisan serve to run Laravel.

Error:

NotWritableException in Image.php line 143:
Can't write image data to path (D:\WORK\WebSite\iStore\public\assets/images/products/2015-07-05-08:52:33-6aa3df83gw1dtd5qki2oij.jpg)

Controller:

$image = Input::file('image');
$filename = date('Y-m-d-H:i:s') . "-" . $image->getClientOriginalName();
$path = public_path('assets/images/products/' . $filename);

// echo dd(is_writable(public_path('assets/images/products')));

Image::make($image->getRealPath())-> resize(200, 200)-> save($path);

$product->image = 'assets/images/products/' . $filename;

I used dd(is_writable())to check permission, it is true. And I also try chmod 777 public/assets/images/products

View:

{!! Form::open(array('url' => 'admin/product/update', 'class' => '', 'files' => true)) !!}
<div class="form-group">
{!! Form::Label('image', 'Product Image', array('sr-only')) !!}
<div>
{!! HTML::image($product->image, $product->title, array('class' => 'img-rounded', 'height' => '200')) !!}
</div>
<hr/>
{!! Form::file('image', array('class' => 'form-group')) !!}
</div>
{!! Form::close() !!}

What can I do with this error?

Answer 1

Make sure that the Folder you mentioned ie, assets/images/products/ exists and it has writable permission

Make sure that you have a good file name ie, it should not contain : symbol

So you shall change you code like this

$image = Input::file('image');
$filename = date('Y-m-d-H-i-s')."-". $image->getClientOriginalName();
$path = public_path('assets/images/products/'.$filename);
Image::make($image->getRealPath())-> resize(200, 200)-> save($path);

You problem might lie with the fact that you are using reserved characters within your file name. In Windows you cannot use colons : in file names. So you might want to replace the colons with dashes or something else, maybe like so:

$filename = date('Y-m-d_H-i-s') . "-" . $image->getClientOriginalName();

If readability is not a requirement here, and you're using the date and time to create unique filenames, you could just prepend a UNIX timestamp to the filename:

$filename = time() . "-" . $image->getClientOriginalName();

You might want to read the Naming Files, Paths, and Namespaces documentation on MSDN for more information about the subject.
