laravel-admin 添加Excel导入功能

Laravel  /  管理员 发布于 2020-04-14 17:18:55   2796

1. 引入laravel-excel；
   

2. 添加导入按钮：

 //导入
 $grid->tools(function ($tools) {
   $tools->append(new ExcelImport());
 });
 //导出
 $grid->exporter(new ExcelExporter('cardnews'));

   

   3. 导入按钮控制器 

<?php
namespace App\Admin\Extensions\Tools;
use Encore\Admin\Admin;
use Encore\Admin\Grid\Tools\AbstractTool;
use Illuminate\Support\Facades\Request;

class ExcelImport extends AbstractTool
{
    public function script()
    {
        return <<<EOT
   $('.file-upload').on('change', function () {
        $('.file-upload-form').submit();
    });
EOT;
    }
    public function render()
    {
        Admin::script($this->script());
        if (Request::path() == 'loansarticles'){
            $url = 'loansnewsimport';
        }else {
            $url = 'cardnewsimport';
        }
        return view('admin.tools.excelimport')->with('url',$url);
    }
}

  4. 按钮视图：\resources\views\admin\tools\excelimport.blade.php

<label class="btn btn-success"{{-- data-toggle="modal" data-target="#uploadModal"--}}>
    <i class="fa fa-stack-overflow"></i>&nbsp;&nbsp;数据导入
    <form action="{{$url}}" method="post" class="file-upload-form" enctype="multipart/form-data" pjax-container>
        <input type="file" name="files[]" class="hidden file-upload" multiple>
        {{ csrf_field() }}
    </form>
</label>

  5. 导入的方法：重组数据拼sql,插入数据库

public function import(Request $request)
 {
     $files = $request->file('files');
     $dir = $request->get('dir', '/');
     $manager = new MediaManager($dir,'xlsx');
     try {
         //文件上传服务器
         if ($manager->upload($files)) {
             admin_toastr('导入成功');
         }
         //文件存储路径
         $filePath = "/data/www/cbb_new/storage/app/public/".$files[0]->getClientOriginalName();

         Excel::load($filePath, function($reader) {
             $data = $reader->all();
             //dd($data);
             //批量存储
             $value=[];
             $lastid = CardArticle::orderBy('id','desc')->limit(1)->value('id');
             foreach ($data as $k => $v ){
                 $lastid++;
                 //存储表格每行的值
                 $value['title']    =$v['title'];
                 $value['dt'] =date('Y-m-d H:i:s');
                 $value['seotitle'] =$v['seotitle'];
                 $value['keywords'] =$v['keywords'];
                 $value['author']   =$v['author'];
                 $value['class_id'] = intval($v['class_id']);
                 $value['bank_id']  =intval($v['bank_id']);
                 $value['content']  =$v['content'];
                 $value['views']    =intval($v['views']);
                 $value['order']    =intval($v['order']);
                 $value['generate_url']=  '/cardnews/cardnews_'.$lastid.'.shtml';
                 $value['status']   =intval($v['status']);

                 CardArticle::create($value);
             }
         });

     } catch (\Exception $e) {
         admin_toastr($e->getMessage(), 'error');
     }
     return back();
 }

    6. 写路由：admin\routes.php  我的方法写在CardArticleController控制器里面

$router->any('cardnewsimport', 'CardArticleController@import');

    7. Models里面添加要导入的字段

protected $fillable = ['xx','xx',...]

    完成 看看效果 表格文件/导入后截图
