dcat admin 多文件上传

问题描述

需要解决dcat admin 表单多附件管理的(附件名和保存文件名分开保存)

解决方案

上传文件管理

  • 首先是新建上传文件表

    Schema::create('uploads', function (Blueprint $table) {
    $table->string('disk', 30)->comment('存储位置');
    $table->string('type', 20)->default('file')->comment('文件类型');
    $table->string('name', 150)->nullable()->comment('文件名称');
    $table->string('path', 150)->comment('文件路径');
    });
  • 新建上传文件用的路由

    $router->any('/upload/handle/{disk}/{dir}', 'UploadController@handle');
  • 上传处理

    public function handle($diskName, $dir) {
        $disk =$this->disk($diskName);
    
        // 判断是否是删除文件请求
        if ($this->isDeleteRequest()) {
            Upload::where('path', request()->key)->delete();
            // 删除文件并响应
            return $this->deleteFileAndResponse($disk);
        }
    
        // 获取上传的文件
        $file = $this->file();
        $newName =  Common::uniqueID().'.'.$file->getClientOriginalExtension();
        $result = $disk->putFileAs($dir, $file, $newName);
        $path = "{$dir}/$newName";
        $upload = new Upload;
        $upload->name = request()->name;
        $upload->path = $path;
        $upload->disk = $diskName;
        $upload->save();
    
        return $result
            ? $this->responseUploaded($path, $disk->url($path))
            : $this->responseErrorMessage('文件上传失败');
    }
  • 扩展字段

    class CustomMultiFile extends MultipleFile
    {
    protected function initialPreviewConfig()
    {
        $previews = [];
        foreach ($this->value() as $path => $name) {
            $previews[] = [
                'id'   => $path,
                'path' => Helper::basename($name),
                'url'  => $this->objectUrl($path),
            ];
        }
    
        return $previews;
    }
    }
  • 注册扩展字段

    Form::extend('customMultiFile', CustomMultiFile::class);
  • 表单字段

    $form->customMultiFile('attachment', '附件')->disk('public')
     ->url('upload/handle/public/attachment')
     ->autoUpload()->autoSave(false)
     ->removable(true)->limit(10);
