我如何将图片上传到文章？

Question

请帮帮我，我正在想办法Laravel，还是不行。我已经创建了表格。建立了联系。创建控制器。它似乎是正确规定的。我不再明白如何做到在表格中你可以给这篇文章添加图片然后显示它。请帮助笨蛋。我需要我的函数为这篇文章上传一张图片，然后它才能显示。您最有可能需要以某种方式插入到 "create" 函数中。请帮忙。

创建文章表

public function up()
{
    Schema::create('articles', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->string('slug');
        $table->text('description_short')->nullable();
        $table->text('description')->nullable();
        $table->string('meta_title')->nullable();
        $table->string('meta_description')->nullable();
        $table->string('meta_keyword')->nullable();
        $table->boolean('published')->nullable();
        $table->integer('viewed')->nullable();
        $table->integer('created_by')->nullable();
        $table->integer('modified_by')->nullable();


        $table->string('image_path'); //There image path
        $table->timestamps();
    });
}

ArticleController.php

class ArticleController extends Controller
{
 public function store(Request $request)
    {

        $article = Article::create($request->all());

        if($request->input('categories'))  :
            $article->categories()->attach($request->input('categories'));
        endif;
        return redirect()->route('admin.article.index');    
    }
    public function index()
    {
        return view('admin.articles.index',[
            'articles' => Article::orderBy('created_at', 'desc')->paginate(10)
        ]);
    }

   public function create()
    {   
        return view('admin.articles.create',[
            'article' => null,
            'categories' => Category::with('children')->where('parent_id',0)->get(),
            'delimiter' => ''
        ]);
    }


 function upload(Request $request)
    {
     $this->validate($request, [
      'select_file'  => 'required|image|mimes:jpg,png,gif|max:2048'
     ]);

     $image = $request->file('select_file');

     $new_name = rand() . '.' . $image->getClientOriginalExtension();

     $image->move(public_path('images'), $new_name);
     return back()->with('success', 'Image Uploaded Successfully')->with('path', $new_name);
    }

Answer 1

通过enctype属性指定表单可以post个文件

<form class="form-horizontal" action="{{route('admin.article.store')}}" 
method="post" enctype="multipart/form-data">

并利用控制器中的upload方法

public function store(Request $request)
{
    $new_name = $this->upload($request);
    $article = Article::create([
        'title' => $request->title,
        'slug' => $request->slug,
        'description_short' => $request->description_short,
        'description' => $request->description,
        'meta_title' => $request->meta_title,
        'meta_description' => $request->meta_description,
        'meta_keyword' => $request->meta_keyword,
        'published' => $request->published,
        'viewed' => 0,
        'created_by' => auth()->id(),
        'modified_by' => auth()->id(),
        'image_path' => $new_name
    ]);
    if ($request->input('categories')) :
        $article->categories()->attach($request->input('categories'));
    endif;
    return redirect()->route('admin.article.index')->with('success', 'Image Uploaded Successfully')->with('path', $new_name);
}

function upload(Request $request)
{
    $this->validate($request, [
        'select_file'  => 'required|image|mimes:jpg,png,gif|max:2048'
    ]);

    $image = $request->file('select_file');

    $new_name = rand() . '.' . $image->getClientOriginalExtension();

    $image->move(public_path('images'), $new_name);
    return $new_name;
}
