Laravel 5关于图像/文件上传的疑问

Question

I'm creating a small institutional website for my company, and there is going to be a Blog(can only post from backoffice, only for admins). I'm having trouble basically with the image upload. I need to store the image link in the database, but I don't know how to move the uploaded image to my resources folder.

This is my first time working with file upload in Laravel, and the documentation is kind of confusing with the Local Storage and Cloud Storage. I'm not really sure which one I need to use...

I only have this in my template:

<label for="image" class="col-md-4 control-label">Upload image</label>
<div class="col-md-6">
    <input id="image" type="file" name="image" required>
</div>

I have no idea how to process this in the controller..

EDIT:

So, after reading more throughly the docs, I think I've understood. Here is what I've got so far:

if ($request->hasFile('image') && $request->file('image')->isValid()) {
     $path = $request->photo->store('image');
}  

But now I'm getting this error: Call to a member function store() on null

I'm using the public drive, since everybody can see the blog posts. Any help?

尝试这个：

$path = $request->image->store('images');

Answer 2

You can use local storage, cloud storage is for example persisting to an Amazon S3 Bucket.

In your controller you can check for and retrieve files using

if (Input::file('image'))
{
    // file is set.
    // Move the file.
   Input::file('image')->move($destinationPath, $fileName);
}

Storing Uploaded Files

To store an uploaded file, you will typically use one of your configured filesystems. The UploadedFile class has a store method which will move an uploaded file to one of your disks, which may be a location on your local filesystem or even a cloud storage location like Amazon S3.

The store method accepts the path where the file should be stored relative to the filesystem's configured root directory. This path should not contain a file name, since a unique ID will automatically be generated to serve as the file name.

The store method also accepts an optional second argument for the name of the disk that should be used to store the file. The method will return the path of the file relative to the disk's root:

$path = $request->photo->store('images');

$path = $request->photo->store('images', 's3');

If you do not want a file name to be automatically generated, you may use the storeAs method, which accepts the path, file name, and disk name as its arguments:

$path = $request->photo->storeAs('images', 'filename.jpg');

$path = $request->photo->storeAs('images', 'filename.jpg', 's3');
