效果图
- 创建按钮
| $grid->tools(function (Grid\Tools $tools) { | |
| // excle 导入 | |
| $tools->append(new Reast()); | |
| }); | |
| 2.app/admin/actions/grid 下创建 Reast.php | |
| namespace App\Admin\Actions\Grid; | |
| use App\Admin\Actions\Form\Import; | |
| use Dcat\Admin\Admin; | |
| use Dcat\Admin\Actions\Response; | |
| use Dcat\Admin\Grid\Tools\AbstractTool; | |
| use Dcat\Admin\Traits\HasPermissions; | |
| use Illuminate\Contracts\Auth\Authenticatable; | |
| use Illuminate\Database\Eloquent\Model; | |
| use Illuminate\Http\Request; | |
| class Reast extends AbstractTool | |
| { | |
| /** | |
| * @return string | |
| */ | |
| protected $title = 'Title'; | |
| public function render() | |
| { | |
| $id = "reset-pwd-{$this->getKey()}"; | |
| // 模态窗 | |
| $this->modal($id); | |
| return <<<HTML | |
| <span class="grid-expand" data-toggle="modal" data-target="#{$id}"> | |
| <a href="javascript:void(0)"><button class="btn btn-outline-info ">上传Excel并导入数据</button></a> | |
| </span> | |
| HTML; | |
| } | |
| protected function modal($id) | |
| { | |
| $form = new Import(); | |
| Admin::script('Dcat.onPjaxComplete(function () { | |
| $(".modal-backdrop").remove(); | |
| $("body").removeClass("modal-open"); | |
| }, true)'); | |
| // 通过 Admin::html 方法设置模态窗HTML | |
| Admin::html( | |
| <<<HTML | |
| <div class="modal fade" id="{$id}"> | |
| <div class="modal-dialog modal-lg" role="document"> | |
| <div class="modal-content"> | |
| <div class="modal-header"> | |
| <h4 class="modal-title">导入数据</h4> | |
| <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> | |
| </div> | |
| <div class="modal-body"> | |
| {$form->render()} | |
| </div> | |
| </div> | |
| </div> | |
| </div> | |
| HTML | |
| ); | |
| } | |
| /** | |
| * @param Model|Authenticatable|HasPermissions|null $user | |
| * | |
| * @return bool | |
| */ | |
| protected function authorize($user): bool{ | |
| return true; | |
| } | |
| /** | |
| * @return array | |
| */ | |
| protected function parameters() | |
| { | |
| return []; | |
| } | |
| } | |
| 3.在Actions/form下创建Import.php | |
| namespace App\Admin\Actions\Form; | |
| use Dcat\Admin\Models\Administrator; | |
| use Dcat\Admin\Widgets\Form; | |
| use Symfony\Component\HttpFoundation\Response; | |
| use App\Imports\DataExcel; | |
| use Maatwebsite\Excel\Facades\Excel; | |
| use Maatwebsite\Excel\Validators\ValidationException; | |
| class Import extends Form | |
| { | |
| public function handle(array $input) | |
| { | |
| $file = env('APP_URL').'/upload/'.$input['file']; | |
| try { | |
| Excel::import(new DataExcel(time()), $input['file'],'public'); | |
| //dcat-2.0版本写法 | |
| return $this->response() | |
| ->success('导入成功') | |
| ->redirect('/'); | |
| //dcat-1.7 | |
| //return $this->success('导入成功'); | |
| } catch (ValidationException $validationException) { | |
| return Response::withException($validationException); | |
| } catch (Throwable $throwable) { | |
| //dcat 2.0写法 | |
| $this->response()->status = false; | |
| return $this->response()->error('上传失败')->refresh(); | |
| //dcat 1.7 | |
| //return $this->error('上传失败')->refresh(); | |
| } | |
| } | |
| public function form() | |
| { | |
| $this->file('file', '上传数据（Excel）')->rules('required', ['required' => '文件不能为空']); | |
| } | |
| } | |
