PHP开发的一个小小项目，记录下实现思路（附上实现功能的示例代码）（三）

接着上次的功能：

   Excle表的导入：

   前端页面：

<form action="__URL__/impUser" method="POST" enctype="multipart/form-data">
		<select name="select" id="" class="form-control">
			<option value="1">基本信息</option>
			<option value="2">工作情况</option>
			<option value="3">奖惩情况</option>
			<option value="4">资助情况</option>
			<option value="5">xxxxxxx</option>
			<option value="6">xxxxxxx</option>
		</select>
<input type="file" class="form-control" name="file" id="file1"/>

<div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">关闭
  </button>
  <input type="submit" class="btn btn-primary" id="sureChange" value="确认导入" />			
</div>
</form>

控制器中：

function impUser(){
        if($_FILES['file']['name']==''){
            echo "<script type='text/javascript'>alert('导入文件不能为空');</script>";
            $URL=U('admin/TheList/index');
            echo "<script type='text/javascript'>
            window.location.href = '$URL';
            </script>";
            exit;
        }

	D(Member)->impUser();
}

模版中：

function impUser(){
    $impType = $_POST['select'];  //接收select,用于选择导入类型
        if (!empty($_FILES)) {
            $config=array(
                'allowExts'=>array('xlsx','xls'),
                'savePath'=>'./Public/upload/',
                'saveRule'=>'time',
            );
            $upload = new \Think\UploadFile($config);
            if (!$upload->upload()) {
                $this->error($upload->getErrorMsg());
            } else {  // 上传成功 获取上传文件信息
                $info = $upload->getUploadFileInfo();  
                
            }
    //导入PHPExcel类库，因为PHPExcel没有用命名空间，只能inport导入
		import("Org.Util.PHPExcel");
		import("Org.Util.PHPExcel.Reader.Excel5");
		import("Org.Util.PHPExcel.Reader.Excel2007");
		import("Org.Util.PHPExcel.IOFactory.php");
                import("Org.Util.PHPExcel.Shared.Date.php");

                /*有文件上传引用上传类，返回文件名*/             
                
                $file=$info['0']['savepath'].$info['0']['savename'];  
                if($file){                 
                 //导入excel类                                        
                 /*获取Excel文件类型，确定版本*/                 
                 $extend=pathinfo($file);         //返回文件路径的信息          
                 $extend = strtolower($extend["extension"]);     //将字符串转化为小写            
                 $extend=='xlsx'?$reader_type='Excel2007':$reader_type='Excel5';                 
		 $objReader =  new \PHPExcel_IOFactory;
		 $objReader = $objReader::createReader($reader_type);
                 if(!$objReader){                     
                 //执行失败，直接抛出错误中断          
                    echo "<script type='text/javascript'>alert('抱歉！excel文件不兼容。');</script>";
                               //echo "<script type='text/javascript'>alert($value);</script>";
