我们做网站的时候经常要用到excel导入和导出的功能，我们通常的做法是用phpexcel工具包来完成，具体方法如下：
html代码：
<form action="{:U('Mall/updExcel')}" method="POST" enctype="multipart/form-data"> //提交form表单到Mall控制器下的upExcel方法中 <div style="float:left;width:41%;"> <div style="float:left;"> <input type='submit' value="更改价格" style="margin: 0px 0px 7px 10px;cursor: pointer;background-color:#C30D23;border:0px;color:#FFFFFF;width:90px;border-radius:5px;padding:3px 0;font-size:13px;"/> </div> <div style="float:left;width:45%"> <input type='file' value="" name="import"/> </div> <input type="hidden" id="url" name="url" value=""/> //添加一个隐藏域 传递url </div>
</form>
写ExcelController工具类：此类用来被实例化
<?php namespace Home\Controller; use Think\Controller; include "./Public/Plugin/PHPExcel.class.php"; include "./Public/Plugin/PHPExcel/Writer/Excel5"; include "./Public/Plugin/PHPExcel/IOFactory.php"; class ExcelController extends Controller { //导入功能 public function updExcel($file){ if(!file_exists($file)){ return array("error"=>0,'message'=>'file not found!'); } $objReader = \PHPExcel_IOFactory::createReader('Excel5'); $objPHPExcel = $objReader->load($file,$encode='utf-8'); $sheet = $objPHPExcel->getSheet(0); $highestRow = $sheet->getHighestRow(); // 取得总行数 $highestColumn = $sheet->getHighestColumn(); // 取得总列数 $j=0; for($i=2;$i<=$highestRow;$i++){ $data[$j]['id']= $objPHPExcel->getActiveSheet()->getCell("A".$i)->getValue(); $data[$j]['result_price']= $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue(); $j++; } return $data; }
下面书写控制器来上传excel表格：此类方法不用把excel表格传递到服务器，直接写入数据：
<?php namespace Admin\Controller; use Think\Controller; use Think\Page; use Home\Controller\IndexController; use Common; use Org\Util\Date; use Home\Controller\ExcelController; class MallController extends Controller { /*商品列表批量导入*/ public function updExcel(){ $excel=new ExcelController(); $goods=M('shop_goods_subinfo'); if(isset($_FILES["import"]) && ($_FILES["import"]["error"] == 0)){ $result = $excel->updExcel($_FILES["import"]["tmp_name"]); /* * 业务逻辑代码 * */ $true=""; $false=""; foreach($result as $value){ //$where=array('id'=>$value['id'],'status'=>0); $where=array( 'code'=>$value['id'], ); $data=array( 'result_price'=>$value['result_price'], ); $state=$goods->where($where)->save($data); if($state > 0){ $true .= ";".$value['id']; }else{ $false .= ";".$value['id']; } } echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />'; echo "<script type='text/javascript'>"; echo "alert('更改成功".$true.";更改失败".$false."');window.location.href='".I('param.url')."';"; echo "</script>"; exit; }else{ echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />'; echo "<script type='text/javascript'>"; echo "alert('文件读取失败');window.location.href='".I('param.url')."';"; echo "</script>"; exit; } } }
