TP5使用Composer安装PhpSpreadsheet类导出Excel

1.加载

use PhpOffice\PhpSpreadsheet\Spreadsheet;

use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

 

2.方法

public function outExcel()

{

// 1.查询列表

$week_start_time = input('param.week_start_time');

$week_end_time = input('param.week_end_time');

$user_id = input('param.user');

 

// 统计

$sql = "SELECT a.*,b.title,c.nickname,d.depart_name

from boot_weekly a

left join boot_product b on a.pd_id = b.id

left join boot_admin c on a.mt_user_id = c.id

left join boot_depart_group d on c.depart_id = d.id

where 1=1 and a.`status`='0' and b.`status`='0' and c.`status`='0' and d.`status`='0' ";

 

// 查询条件--日期

if (!empty($week_start_time) && !empty($week_end_time)) {

$week_end_time = date($week_end_time, strtotime('+1 day'));

$sql .= ' and week_start_time between "' . $week_start_time . '" and "' . $week_end_time . '"';

} else if (!empty($week_start_time) && empty($week_end_time)) {

$sql .= ' and pd_start_time >= "' . $week_start_time . '"';

} else if (empty($week_start_time) && !empty($week_end_time)) {

$week_end_time = date($week_end_time, strtotime('+1 day'));

$sql .= ' and week_start_time <= "' . $week_end_time . '"';

}

if ($user_id !== '0' && !empty($user_id)) {

$sql .= ' and c.id= ' . $user_id;

}

$sql .= ' order by d.id';

$list = db("boot_weekly")->query($sql);

 

// 2.导出

$newExcel = new Spreadsheet(); //创建一个新的excel文档

$objSheet = $newExcel->getActiveSheet(); //获取当前操作sheet的对象

$objSheet->setTitle('周报信息表'); //设置当前sheet的标题

 

$newExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('E')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('F')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('G')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('H')->setAutoSize(true);

$newExcel->getActiveSheet()->getColumnDimension('I')->setAutoSize(true);

 

$objSheet->setCellValue('A1', '序号')

->setCellValue('B1', '周报期号')

->setCellValue('C1', '部门')

->setCellValue('D1', '人员')

->setCellValue('E1', '项目')

->setCellValue('F1', '完成事项')

->setCellValue('G1', '工作日期')

->setCellValue('H1', '截止日期')

->setCellValue('I1', '困难/难点');

 

/*--------------开始从数据库提取信息插入Excel表中------------------*/

//$i=2; //定义一个i变量，目的是在循环输出数据是控制行数

$count = count($list); //计算有多少条数据

 

for ($i = 2; $i <= $count + 1; $i++) {

$id = $i - 1;

 

$objSheet->setCellValue('A' . $i, $sql[$i - 2][$id])

->setCellValue('B' . $i, '第' . $list[$i - 2]['week_start_time'] . '期')

->setCellValue('C' . $i, $list[$i - 2]['depart_name'])

->setCellValue('D' . $i, $list[$i - 2]['nickname'])

->setCellValue('E' . $i, $list[$i - 2]['title'])

->setCellValue('F' . $i, $list[$i - 2]['pd_mt'])

->setCellValue('G' . $i, $list[$i - 2]['mt_start_time'] . '至' . $list[$i - 2]['mt_end_time'])

->setCellValue('H' . $i, $list[$i - 2]['mt_deadline'])

->setCellValue('I' . $i, $list[$i - 2]['mt_df']);

}

 

/*--------------下面是设置其他信息------------------*/

header('Content-Type: application/vnd.ms-excel');

header("Content-Disposition: attachment;filename=".'周报信息' . ".xls");

header('Cache-Control: max-age=0');

$objWriter = new Xlsx($newExcel);

$objWriter->save('php://output');

 

//通过php保存在本地的时候需要用到

//$objWriter->save($dir.'/demo.xlsx');

 

//以下为需要用到IE时候设置

exit();

}

 

3.前端

html中：

style="line-height: 25px;"> 导出

js：

$('#export').click(function () {

var url = "{:url('admin/Search/outExcel')}"

+ '?week_start_time=' + $('#week_start_time').val()

+ '&week_end_time=' + $('#week_end_time').val()

+ '&user=' + $("#user").val();

$('#export').attr('href', url);

}）
