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, '&');
}

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>

javascript方法 ed()

//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
}

php controller层数据导出的方法

use common\components\Myhelpers;
/**
* @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

Myhelpers::exportData($data, $header, '表头', '文件名称');
}

php 导出excel方法（缺点：导出数据的列数大于26时报错，优化见下）

*  @return void, Browser direct output
