<form class="layui-form layui-col-md12 x-so" action="{:url('admin/fangwei/daochu')}" method="get">
<input type="text" name="fw_pici" value="{$fw_pici ? $fw_pici : '';}" placeholder="请输入印刷批次" class="layui-input">

</form> 控制器代码//导出xls
public function daochu(){
//1.从数据库中取出数据
$where =input('param.fw_pici');
//halt($where);
$list = Db('fangwei')->where('fw_pici','=',$where)->order('fw_id ASC')->select();
//halt($list);
//2.加载PHPExcle类库
vendor('PHPExcel.PHPExcel');
//3.实例化PHPExcel类
$objPHPExcel = new \PHPExcel();
//4.激活当前的sheet表
$objPHPExcel->setActiveSheetIndex(0);
//5.设置表格头（即excel表格的第一行）
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'ID')
->setCellValue('B1', '防伪码')
->setCellValue('C1', '标签码');
//设置A列水平居中
$objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()
->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
//设置单元格宽度
$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('A')->setWidth(10);
$objPHPExcel->setActiveSheetIndex(0)->getColumnDimension('B')->setWidth(30);
//6.循环刚取出来的数组，将数据逐一添加到excel表格。
for($i=0;$i<count($list);$i++){
$objPHPExcel->getActiveSheet()->setCellValue('A'.($i+2),$list[$i]['fw_id']);//ID
$objPHPExcel->getActiveSheet()->setCellValue('C'.($i+2),$list[$i]['fw_biaoqianma']);//标签码
$objPHPExcel->getActiveSheet()->setCellValue('B'.($i+2),$list[$i]['fw_fangweima']);//防伪码
}
//7.设置保存的Excel表格名称
$filename = '印刷防伪码'.date('ymd',time()).'.xls';
//8.设置当前激活的sheet表格名称；
$objPHPExcel->getActiveSheet()->setTitle('防伪码');
//9.设置浏览器窗口下载表格
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header('Content-Disposition:inline;filename="'.$filename.'"');
//生成excel文件
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
//下载文件在浏览器窗口
$objWriter->save('php://output');
exit;
