使用Laravel 5上传pdf文件 [英] Upload pdf file using Laravel 5

问题描述

我正在使用Laravel 5.2，我想制作一个可以上传pdf文件的表格.我想将该文件添加到"public"文件夹中的"files"文件夹中.

这是我的观点:

I'm using Laravel 5.2 and I want to make a form which can upload a pdf file with it. I want to add that file on folder "files" in "public" folder.

here is my view:

<div class="form-group">
     <label for="upload_file" class="control-label col-sm-3">Upload File</label>
     <div class="col-sm-9">
          <input class="form-control" type="file" name="upload_file" id="upload_file">
     </div>
</div>

接下来我该怎么办?我应该在控制器和路由中添加什么?

and what should I do next? what should I add in my controller and route?

推荐答案

首先，您应该将enctype="multipart/form-data"添加到<form>标记中.然后在您的控制器中按以下方式处理文件上传:

First you should add enctype="multipart/form-data" to your <form> tag. Then in your controller handle the file upload as follow:

class FileController extends Controller
{
    // ...

    public function upload(Request $request)
    {
        $uniqueFileName = uniqid() . $request->get('upload_file')->getClientOriginalName() . '.' . $request->get('upload_file')->getClientOriginalExtension());

        $request->get('upload_file')->move(public_path('files') . $uniqueFileName);

        return redirect()->back()->with('success', 'File uploaded successfully.');
    }

    // ...
}

链接到用于处理文件上传的Laravel文档

Laravel在请求中将文件类型参数转换为UploadedFile对象.您可以在此处中看到Symfony的UploadedFile类.方法和属性.

Laravel casts the file type params in request to UploadedFile objects. You can see Symfony's UploadedFile class here for available methods and attributes.
