Laravel 5.6 图片上传,将文章 slug 作为图片名称保存在数据库中

Laravel 5.6 Image Upload, Save article slug as image name in database

我正在使用 Laravel 5.6 和 Collective HTML。

我有一篇 table 篇文章,我正在创建一个表单来上传一篇文章

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.');
}

当我创建文章时,会根据标题自动形成一个 slug。我想要实现的是上传一个图像文件(jpg、png、jpeg)并将图像名称保存到数据库和图像到 public/uploads/articles 文件夹。

当我说图片名称时,我希望图片名称是文章的别名,例如

如果我创建Article 1,自动创建一个slug article-1,我希望图片名称为article-1.jpg(图片扩展名)保存在数据库中并保存图片article -1.jpg 到 public 文件夹。

如何重命名文件并实现此功能。

保存文章后 $article->save() 该对象及其所有方法等都可供您使用。

您正在使用的 slug 包包含 ->slug 属性 作为 sluggable 特征的一部分,因此您可以(如果您使用的是 Storage facade)做一些事情喜欢;

Storage::put($article->slug.'jpg', $request->file('file_field'));

或者如果您不使用 flystem 实现,您可以像这样存储文件:

$request->photo->storeAs('images', $article->slug.'jpg');

$request->photo 是您表单中的文件字段。

显然您需要对文件执行某种处理以获得它的 mime 类型(它可能不是 jpg)并可能调整大小 it/crop 它等,但这应该让您开始。

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.');
}

以上代码会将标题转换为 slug,并将名称的图像保存为 slug。

希望对您有所帮助。
