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, $header); * @return void, Browser direct output */ public static function exportData ($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;
$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 $hk = 0; foreach ($header as $k => $v) { $colum = \PHPExcel_Cell::stringFromColumnIndex($hk); $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($colum.‘1‘, $v); $hk += 1; }
$column = 2; $objActSheet = $objPHPExcel->getActiveSheet(); foreach($data as $key => $rows) //行写入 { $span = 0; foreach($rows as $keyName => $value) // 列写入 { $j = \PHPExcel_Cell::stringFromColumnIndex($span); $objActSheet->setCellValue($j.$column, $value); $span++; } $column++; }
// 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‘); }
