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<br />$paramsExcel = ''; //这个参数是控制接收view层GridView::widget filter的参数<br />if ( ($params = Yii::$app->request->queryParams) )<br />{<br />    if ($params && isset($params['xxSearch']) && $params['xxSearch'])<br />    {<br />        foreach ($params['xxSearch'] as $k => $v) <br />        {<br />            if ($v)<br />            {<br />                $paramsExcel .= $k.'='.$v.'&';<br />            }<br />        }<br /><br />    }<br />    $paramsExcel = rtrim($paramsExcel, '&');<br />}

//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;"><br />        <?= Html::a('导出', 'javascript:ed();', ['class' => 'btn btn-success']) ?><br />        开始时间：<input type="text" name="start_time" /><br />        结束时间：<input type="text" name="end_time" /><br /></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<br />function ed ()<br />{<br />    var paramsExcel = "<?php echo $paramsExcel; //controller传递过来的参数?>", <br />        url = '/xx/export-data', //此处xx是控制器<br />        startTime = $.trim($('input[name=start_time]').val()), <br />        endTime = $.trim($('input[name=end_time]').val()),<br />        temp = '';<br />    <br />    //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<br />    if (paramsExcel)<br />    {<br />        temp += '?'+paramsExcel;<br />        if (startTime)<br />            temp += '&start_time='+startTime;<br />        <br />        if (endTime)<br />            temp += '&end_time='+endTime;<br />    } <br />    else if (startTime)<br />    {<br />        temp += '?start_time='+startTime;<br />        if (endTime)<br />            temp += '&end_time='+endTime;<br />    }<br />    else if (endTime)<br />    {<br />        temp += '?end_time='+endTime;<br />    }<br />    url += temp;<br />    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<br />}

//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;<br />    /**<br />     * @DESC 数据导出<br />     */<br />    public function actionExportData ()<br />    {<br />        $where = '1';<br />        $temp = '';<br />        if ($_GET)<br />        {<br />            foreach ($_GET as $k => $v)<br />            {<br />                if ($k == 'start_time')<br />                {<br />                    $t = date('Y-m-d', strtotime($v)).' 00:00:00';<br />                    $temp .= 'create_time >= \''. $t . '\' AND ';<br />                }<br />                elseif ($k == 'end_time')<br />                {<br />                    $t = date('Y-m-d', strtotime($v)).' 23:59:59';<br />                    $temp .= 'create_time <= \''. $t . '\' AND ';<br />                }<br />                else<br />                {<br />                    $temp .= $k . '=\'' . $v . '\' AND ';<br />                }<br />            }<br />            $temp = rtrim($temp, ' AND');<br />        }<br /><br />        if ($temp) $where .= ' AND '.$temp;<br />        <br />        //查询数据<br />        $data = ......<br /><br />        if ($data)<br />        {<br />            //数据处理<br />        }<br />        <br />        $header = ['id', '用户账号', '创建时间']; //导出excel的表头<br /><br />        CommonFunc::exportData($data, $header, '表头', '文件名称');<br />    }

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：

   /**<br />     *  @DESC 数据导出 <br />     *  @notice max column is z OR 26,overiload will be ignored<br />     *  @notice 缺点：导出数据的列数大于26时报错<br />     *  @example <br />     *  $data = [1, '小明', '25'];<br />     *  $header = ['id', '姓名', '年龄'];<br />     *  Myhelpers::exportData($data, $header);<br />     *  @return void, Browser direct output<br />     */<br />    public static function exportData ($data, $header, $title = 'simple', $filename = 'data')<br />    {<br />        //require relation class files<br />        require(Yii::getAlias('@common').'/components/phpexcel/PHPExcel.php');<br />        require(Yii::getAlias('@common').'/components/phpexcel/PHPExcel/Writer/Excel2007.php');<br />    <br />        if (!is_array ($data) || !is_array ($header)) return false;<br /><br />        //列数<br />        $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'];<br /><br />        $objPHPExcel = new \PHPExcel();<br /><br />        // Set properties<br />        $objPHPExcel->getProperties()->setCreator("Maarten Balliauw");<br />        $objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");<br />        $objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");<br />        $objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");<br />        $objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");<br /><br />        // Add some data<br />        $objPHPExcel->setActiveSheetIndex(0);<br /><br />        //添加头部<br />        $cheader = count($header);<br />        for ($ci = 1; $ci <= $cheader; $ci++) <br />        {<br />            if ($ci > 25) break; <br />            $objPHPExcel->getActiveSheet()->SetCellValue($captions[$ci-1].'1', $header[$ci-1]);<br />        }<br /><br />        //添加数据<br />        $i = 2;<br />        $count = count($data);<br /><br />        foreach ($data as $v)<br />        {<br />            $j = 0;<br />            foreach ($v as $_k => $_v)<br />            {<br />                $objPHPExcel->getActiveSheet()->SetCellValue($captions[$j].$i, $_v);<br />                $j++;<br />            }<br />            if ($i <= $count)<br />            {<br />                $i ++;<br />            }<br />        }<br /><br />        // Rename sheet<br />        $objPHPExcel->getActiveSheet()->setTitle($title);<br /><br />        // Save Excel 2007 file<br />        $objWriter = new \PHPExcel_Writer_Excel2007($objPHPExcel);<br /><br />        header('Pragma:public');<br />        header("Content-Type:application/x-msexecl;name=\"{$filename}.xls\"");<br />        header("Content-Disposition:inline;filename=\"{$filename}.xls\"");<br /><br />        $objWriter->save('php://output');<br />    <br />    }

下面是最终的解决方案，也是非常实用的数据导出方案
