excel/maatwebsite3.1在标题行上一行添加动态查询数据，并导出多sheet
- 首先下载安装好maatwebsite3.1包,具体操作自行百度，进入主题
- 新建导出路由，控制器，导出业务类。在创建路由后，在控制器中做如下处理：
public function export_comments(Request $request)
{
//控制器中调用导出业务类的方法
return (new ExportComment)->export_options($request)->download('活动风采评价.xlsx', \Maatwebsite\Excel\Excel::XLSX);
}
- 此处导出的是多sheet的excel，会有多个导出业务类，每个类处理不同的业务，导出业务类中如下：
ExportComment .php 是主业务导出类
namespace Ano\Comment\Repositories\Backend;
use Illuminate\Http\Request;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;
use Modules\Auth\Entities\Area;
class ExportComment implements WithMultipleSheets
{
use Exportable;
//处理传入的参数
public function export_options(Request $request)
{
$this->started_time = $request->input('started_time', Date("Y-01-01 00:00:00"));//开始时间
$this->ended_time = $request->input('ended_time', Date("Y-m-d H:i:s"));//结束时间
$this->area_id = $request->input('area_id');
if($this->area_id){
$area = Area::find($this->area_id);
if(!$area){
throw new \Exception('区域id不存在', 400);
}
$this->level = $area->level;
}else{
$this->area_id = 2424;
$this->level = 3;
}
return $this;
}
//导出多sheet
public function sheets(): array
{
//按照实践员星级评分 获取活动风采评论排名
//活动的活动风采星级产生的活动排名
$sheets = [];
$sheets[] = new ActivityComment( $this->started_time, $this->ended_time, $this->area_id, $this->level);//按活动风采星级排序活动
$temp = $this->level + 1;
for($i = $temp; $i<= 5; $i++){
$sheets[] = new ActivityCommentLevel( $this->started_time, $this->ended_time, $this->area_id, $this->level, $i);//4、5级按照星级排名
}
return $sheets;
}
}
