学习源自于:http://www.thinkphp.cn/topic/14005.html
- 1.下载PHPExcel包
参考:https://github.com/PHPOffice/PHPExcel -
2.解压PHPExcel
thinkphp中在路径为:ThinkPHP->Library->Vendor中新建文件夹PHPExcel,之后再把红框选中的两个文件,新建的PHPExcel文件夹中。
- 3.前端代码
<html>
<head>
</head>
<body>
<P><a href="__CONTROLLER__/expUser" >导出数据并生成excel</a></P><br/>
<form action="{:U('Index/impUser')}" method="post" enctype="multipart/form-data">
<input type="file" name="import"/>
<input type="hidden" name="table" value="tablename"/>
<input type="submit" value="导入"/>
</form>
</body>
</html>
- 4.后台代码
<?php
// 本类由系统自动生成,仅供测试用途
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
/**
*
* Enter 导出excel共同方法 ...
* @param unknown_type $expTitle
* @param unknown_type $expCellName
* @param unknown_type $expTableData
*/
function index(){
//显示前端页面
$this->display();
}
public function exportExcel($expTitle,$expCellName,$expTableData){
$xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称
$fileName = $_SESSION['account'].date('YmdHis');//or $xlsTitle 文件名称可根据自己情况设定
$cellNum = count($expCellName);
$dataNum = count($expTableData);
vendor("PHPExcel.PHPExcel");
$objPHPExcel = new \PHPExcel();
$cellName = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','AA','AB','AC','AD','AE','AF','AG','AH','AI','AJ','AK','AL','AM','AN','AO','AP','AQ','AR','AS','AT','AU','AV','AW','AX','AY','AZ');
$objPHPExcel->getActiveSheet(0)->mergeCells('A1:'.$cellName[$cellNum-1].'1');//合并单元格
// $objPHPExcel->setActiveSheetIndex(0)->setCellValue('A1', $expTitle.' Export time:'.date('Y-m-d H:i:s'));
for($i=0;$i<$cellNum;$i++){
$objPHPExcel->setActiveSheetIndex(0)->setCellValue($cellName[$i].'2', $expCellName[$i][1]);
}
// Miscellaneous glyphs, UTF-8
for($i=0;$i<$dataNum;$i++){
for($j=0;$j<$cellNum;$j++){
$objPHPExcel->getActiveSheet(0)->setCellValue($cellName[$j].($i+3), $expTableData[$i][$expCellName[$j][0]]);
}
}

header("Content-Disposition:attachment;filename=$fileName.xls");//attachment新窗口打印inline本窗口打印
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
}
/**
* 导出Excel
* 其实在使用导出excel时,只需要根据需求修改此函数即可
*/
function expUser(){//导出Excel
$xlsName = "User";
//excel表中的第一行各列的属性名,即取的数据
$xlsCell = array(
array('id','账号序列'),
array('name','名字'),
array('birth','出生年'),
array('create_time','创建时间'),
array('status','状态'),
);
//数据库中数据表
$xlsModel = M('New');
//取出的所有数据
$xlsData = $xlsModel->Field('id,name,birth,create_time,status')->select();
$this->exportExcel($xlsName,$xlsCell,$xlsData);
}
/**
*
* 显示导入页面 ...
*/
/**实现导入excel
**/
function impUser(){
if (!empty($_FILES)) {
//import("@.ORG.UploadFile");
$config=array(
'exts'=>array('xlsx','xls'),
'rootPath'=>"./Public/",
'savePath'=>'Uploads/',
//'autoSub' => true,
'subName' => array('date','Ymd'),
);
$upload = new \Think\Upload($config);
if (!$info=$upload->upload()) {
$this->error($upload->getError());
}
vendor("PHPExcel.PHPExcel");
$file_name=$upload->rootPath.$info['import']['savepath'].$info['import']['savename'];
//var_dump($file_name);exit;
$objReader = \PHPExcel_IOFactory::createReader('Excel5');
$objPHPExcel = $objReader->load($file_name,$encode='utf-8');
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumn = $sheet->getHighestColumn(); // 取得总列数
//循环遍历excel每一行数据,插入到数据表中
for($i=3;$i<=$highestRow;$i++)
{
$data['id'] = $objPHPExcel->getActiveSheet()->getCell("A".$i)->getValue();
$data['name'] = $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue();
$data['birth']= $objPHPExcel->getActiveSheet()->getCell("C".$i)->getValue();
$data['create_time']= $objPHPExcel->getActiveSheet()->getCell("D".$i)->getValue();
$data['status']= $objPHPExcel->getActiveSheet()->getCell("E".$i)->getValue();
M('New')->add($data);
}
$this->success('导入成功!');
}else
{
$this->error("请选择上传的文件");
}
}
}
5.在使用过程中函数exportExcel()不需要修改,只需要修改导出与导入函数对应对数据库的操作即可。
总结
好好学习,天天向上,今天也是。
