我有一个表格文章，我正在创建一个表单来上传一篇文章
ArticleController
文章控制器
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
$categories = ArticleCategory::pluck('name', 'id');
return view('backend.articles.create', compact('categories'));
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'input_img' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$article = new Article();
if ($request->hasFile('image')) {
$image = $request->file('image');
$name = str_slug($request->title).'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/uploads/articles');
$imagePath = destinationPath. "/". $name;
$image->move($destinationPath, $name);
$article->image = $name;
}
$article->title = $request->get('title');
$article->category_id = $request->get('category_id');
// $article->image = str_slug($request->get('image'));
$article->subtitle = $request->get('subtitle');
$article->description = $request->get('description');
$article->save();
return back()->with('success', 'Your article has been added successfully. Please wait for the admin to approve.');
}
View
看法
!! Form::open(['route'=>'articles.store']) !!}
<div class="form-group {{ $errors->has('category_id') ? 'has-error' : '' }}">
{!! Form::select('category_id', $categories, null, ['class'=>'form-control', 'placeholder'=>'Choose Category']) !!}
<span class="text-danger">{{ $errors->first('category_id') }}</span>
</div>
<div class="form-group {{ $errors->has('title') ? 'has-error' : '' }}">
{!! Form::text('title', old('title'), ['class'=>'form-control', 'placeholder'=>'Enter Title']) !!}
<span class="text-danger">{{ $errors->first('title') }}</span>
</div>
<div class="form-group {{ $errors->has('subtitle') ? 'has-error' : '' }}">
{!! Form::text('subtitle', old('subtitle'), ['class'=>'form-control', 'placeholder'=>'Upload subtitle']) !!}
<span class="text-danger">{{ $errors->first('subtitle') }}</span>
</div>
<div class="form-group {{ $errors->has('image') ? 'has-error' : '' }}">
{!! Form::file('image', old('image'), ['class'=>'btn-white form-control', 'placeholder'=>'Enter image Url']) !!}
<span class="text-danger">{{ $errors->first('image') }}</span>

</div>
<div class="form-group">
<button class="btn btn-primary">Submit</button>
</div>
{!! Form::close() !!}
I'm using thispackage for slugs
我正在使用这个包来处理蛞蝓
When i create an article a slug is automatically formed based on the title. What i want to achieve is to upload a image file(jpg, png, jpeg) and save the image name to the database and the image to public/uploads/articles folder.
当我创建一篇文章时，会根据标题自动形成一个 slug。我想要实现的是上传图像文件（jpg、png、jpeg）并将图像名称保存到数据库并将图像保存到 public/uploads/articles 文件夹。
When i say image name, i want the imagename to be the slug of the article iike for example
例如，当我说图像名称时，我希望图像名称是文章的 slug
If i create Article 1, a slug is automatically created article-1, i want the image name to be article-1.jpg(the image extension) to be saved in the database and save the image article-1.jpg to the public folder.
如果我创建文章1，会自动创建一个slug文章1，我希望图像名称为article-1.jpg（图像扩展名）保存在数据库中并将图像article-1.jpg保存到公共文件夹。

You can use the following code to store the file and slug in your database
您可以使用以下代码将文件和 slug 存储在您的数据库中
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
$this->validate($request, [
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$article = new Article();
if ($request->hasFile('image')) {
$image = $request->file('image');
$name = str_slug($request->title).'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('/uploads/articles');
$imagePath = $destinationPath. "/". $name;
$image->move($destinationPath, $name);
$article->image = $name;
}
$article->title = $request->get('title');
$article->category_id = $request->get('category_id');
// $article->image = str_slug($request->get('image'));
$article->subtitle = $request->get('subtitle');
$article->description = $request->get('description');
$article->save();
return back()->with('success', 'Your article has been added successfully. Please wait for the admin to approve.');
}
Above code will convert the title into a slug and save the image of the name as a slug.
上面的代码将标题转换为一个slug，并将名称的图像保存为一个slug。
Hope this helps.
希望这可以帮助。

Once you have saved the article $article->save()that object and all of its methods etc become available to you.
保存文章后$article->save()，该对象及其所有方法等都可供您使用。
The slug package you're using includes a ->slugproperty as part of the sluggabletrait, so you can (if you're using the Storage facade) do something like;
您正在使用的 slug 包包含一个->slug属性作为特征的一部分sluggable，因此您可以（如果您使用的是 Storage 外观）执行以下操作；
Storage::put($article->slug.'jpg', $request->file('file_field'));
Or if you're not using the flystem implementation you can store the file like so:
或者，如果您不使用 flystem 实现，则可以像这样存储文件：
$request->photo->storeAs('images', $article->slug.'jpg');
$request->photobeing the file field from your form.
$request->photo是表单中的文件字段。
Obviously you'll want to perform some kind of processing on the file to get it's mimetype (it might not be a jpg) and probably resize it/crop it etc, but this should get you started.
显然，您会希望对文件执行某种处理以获得它的 mimetype（它可能不是 jpg）并可能调整它的大小/裁剪它等，但这应该会让你开始。
