先概括下我們接下來要說的大致內容:
數據列表頁面導出excel數據,
1、可以根據GridView的filter進行搜索數據並導出
2、可以自行擴展數據導出的時間直接導出數據
//先來看controller層,接收GridView參數並做拼接處理
php controller
//傳參導出
$paramsExcel = ''; //這個參數是控制接收view層GridView::widget filter的參數
if ( ($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層我們需要做什麼
php 輸入頁面上的html按鈕
<div >
<?= Html::a('導出', 'javascript:ed();', ['class' => 'btn btn-success']) ?>
開始時間:<input type="text" name="start_time" />
結束時間:<input type="text" name="end_time" />
</div>
上面javascript:ed()方法如下,注意這裡我們拼接了controller層傳遞過來的參數,並自行擴展了時間進行搜索數據
//數據導出
function ed ()
{
var paramsExcel = "<?php echo $paramsExcel; //controller傳遞過來的參數?>",
url = '/xx/export-data', //此處xx是控制器
startTime = $.trim($('input[name=start_time]').val()),
endTime = $.trim($('input[name=end_time]').val()),
temp = '';
//需要把view層GridView::widget filter的參數與我們自行擴展的參數拼接融合
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是我們導出數據的地址,上面的處理都只是進行參數的處理
}
//下面我們來看下導出數據的action,暫且命名為controller層的 actionExportData,其中CommonFunc是我們引入的全局性質的公共方法
use common\components\CommonFunc;
/**
* @DESC 數據導出
*/
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;
//查詢數據
$data = ......
if ($data)
{
//數據處理
}
$header = ['id', '用戶賬號', '創建時間']; //導出excel的表頭
CommonFunc::exportData($data, $header, '表頭', '文件名稱');
}
上面CommonFunc::expertData方法是我們底層擴展php-excel類封裝的公共方法,這裡才是我們要說的關鍵,關於 PHPExcel類文件大家可自行下載
No1. 我們走了一個小的彎,分享給大家看看
CommonFunc::expertData方法如下:
/**
* @DESC 數據導出
* @notice max column is z OR 26,overiload will be ignored
* @notice 缺點:導出數據的列數大於26時報錯
* @example
* $data = [1, '小明', '25'];
* $header = ['id', '姓名', '年齡'];
* Myhelpers::exportData($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;
//列數
$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);
//添加頭部
$cheader = count($header);
for ($ci = 1; $ci <= $cheader; $ci++)
{
if ($ci > 25) break;
$objPHPExcel->getActiveSheet()->SetCellValue($captions[$ci-1].'1', $header[$ci-1]);
}
//添加數據
$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');
}
下面是最終的解決方案,也是非常實用的數據導出方案
/**
* @DESC 數據導
* @notice 解決了上面導出列數過多的問題
* @example
* $data = [1, '小明', '25'];
* $header = ['id', '姓名', '年齡'];
* Myhelpers::exportData($data, $header);
* @return void, Browser direct output
