先概括下我们接下来要说的大致内容:
数据列表页面导出excel数据,
1、可以根据GridView的filter进行搜索数据并导出
2、可以自行扩展数据导出的时间直接导出数据
//先来看controller层,接收GridView参数并做拼接处理
php controller
//传参导出
$paramsExcel = ''; //这个参数是控制接收view层GridView::widget filter的参数
if ( ($params = Yii::$app->request->queryParams) )
{
if ($params && isset($params['xxSearch']) && $params['xxSearch'])
{
foreach ($params['xxSearch'] as $k => $v)
{
if ($v)
{
$paramsExcel .= $k.'='.$v.'&';
}
} }
$paramsExcel = rtrim($paramsExcel, '&');
}
//看view层我们需要做什么
php 输入页面上的html按钮
<div style="margin-bottom: 30px;">
<?= Html::a('导出', 'javascript:ed();', ['class' => 'btn btn-success']) ?>
开始时间:<input type="text" name="start_time" />
结束时间:<input type="text" name="end_time" />
</div>
上面javascript:ed()方法如下,注意这里我们拼接了controller层传递过来的参数,并自行扩展了时间进行搜索数据
//数据导出
function ed ()
{
var paramsExcel = "<?php echo $paramsExcel; //controller传递过来的参数?>",
url = '/xx/export-data', //此处xx是控制器
startTime = $.trim($('input[name=start_time]').val()),
endTime = $.trim($('input[name=end_time]').val()),
temp = '';
//需要把view层GridView::widget filter的参数与我们自行扩展的参数拼接融合
if (paramsExcel)
{
temp += '?'+paramsExcel;
if (startTime)
temp += '&start_time='+startTime;
if (endTime)
temp += '&end_time='+endTime;
}
else if (startTime)
{
temp += '?start_time='+startTime;
if (endTime)
temp += '&end_time='+endTime;
}
else if (endTime)
{
temp += '?end_time='+endTime;
}
url += temp;
window.location.href=url; //url是我们导出数据的地址,上面的处理都只是进行参数的处理
}
//下面我们来看下导出数据的action,暂且命名为controller层的 actionExportData,其中CommonFunc是我们引入的全局性质的公共方法
use common\components\CommonFunc;
/**
* @DESC 数据导出
*/
public function actionExportData ()
{
$where = '1';
$temp = '';
if ($_GET)
{
foreach ($_GET as $k => $v)
{
if ($k == 'start_time')
{
$t = date('Y-m-d', strtotime($v)).' 00:00:00';
$temp .= 'create_time >= \''. $t . '\' AND ';
}
elseif ($k == 'end_time')
{
$t = date('Y-m-d', strtotime($v)).' 23:59:59';
$temp .= 'create_time <= \''. $t . '\' AND ';
}
else
{
$temp .= $k . '=\'' . $v . '\' AND ';
}
}
$temp = rtrim($temp, ' AND');
} if ($temp) $where .= ' AND '.$temp;
//查询数据
$data = ...... if ($data)
{
//数据处理
}
$header = ['id', '用户账号', '创建时间']; //导出excel的表头 CommonFunc::exportData($data, $header, '表头', '文件名称');
}
上面CommonFunc::expertData方法是我们底层扩展php-excel类封装的公共方法,这里才是我们要说的关键,关于 PHPExcel类文件大家可自行下载
No1. 我们走了一个小的弯,分享给大家看看
CommonFunc::expertData方法如下:
/**
* @DESC 数据导出
* @notice max column is z OR 26,overiload will be ignored
* @notice 缺点:导出数据的列数大于26时报错
* @example
* $data = [1, '小明', '25'];
* $header = ['id', '姓名', '年龄'];
* Myhelpers::exportData($data, $header);
* @return void, Browser direct output
*/
public static function exportData ($data, $header, $title = 'simple', $filename = 'data')
{
//require relation class files
require(Yii::getAlias('@common').'/components/phpexcel/PHPExcel.php');
require(Yii::getAlias('@common').'/components/phpexcel/PHPExcel/Writer/Excel2007.php');
if (!is_array ($data) || !is_array ($header)) return false; //列数
$captions = ['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']; $objPHPExcel = new \PHPExcel(); // Set properties
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes."); // Add some data
$objPHPExcel->setActiveSheetIndex(0); //添加头部
$cheader = count($header);
for ($ci = 1; $ci <= $cheader; $ci++)
{
if ($ci > 25) break;
$objPHPExcel->getActiveSheet()->SetCellValue($captions[$ci-1].'1', $header[$ci-1]);
} //添加数据
$i = 2;
$count = count($data); foreach ($data as $v)
{
$j = 0;
foreach ($v as $_k => $_v)
{
$objPHPExcel->getActiveSheet()->SetCellValue($captions[$j].$i, $_v);
$j++;
}
if ($i <= $count)
{
$i ++;
}
} // Rename sheet
$objPHPExcel->getActiveSheet()->setTitle($title); // Save Excel 2007 file
$objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel); header('Pragma:public');
header("Content-Type:application/x-msexecl;name=\"{$filename}.xls\"");
header("Content-Disposition:inline;filename=\"{$filename}.xls\""); $objWriter->save('php://output');
}
下面是最终的解决方案,也是非常实用的数据导出方案
/**
* @DESC 数据导
* @notice 解决了上面导出列数过多的问题
* @example
* $data = [1, '小明', '25'];
* $header = ['id', '姓名', '年龄'];
* Myhelpers::exportData($data, $header);
* @return void, Browser direct output
