我是 Codeigniter 的新手。我正在尝试将 gridview 数据导出到 pdf 文件，我正在使用 mpdf 库。我解压缩并放置 \system\helpers 的那个库，我创建了一个 pdfexport_helper.php，它放在 \system\helpers 上。pdfexport_helper.php 这个文件

<?php

if ( ! function_exists('exportMeAsMPDF'))
{
            function exportMeAsMPDF($htmView,$fileName) {

                        $CI =& get_instance();
                        $CI->load->library('MPDF54/mpdf.php');
                       // $CI->mpdf=new mPDF('c','A4','','',32,25,27,25,16,13);
                        $CI->mpdf->AliasNbPages('[pagetotal]');
                        $CI->mpdf->SetHTMLHeader('{PAGENO}/{nb}', '1',true);
                        $CI->mpdf->SetDisplayMode('fullpage');
                        $CI->mpdf->pagenumPrefix = 'Page number ';
                        $CI->mpdf->pagenumSuffix = ' - ';
                        $CII->mpdf->nbpgPrefix = ' out of ';
                        $CI->mpdf->nbpgSuffix = ' pages';
                        $CI->mpdf->SetHeader('{PAGENO}{nbpg}');
                        $CI->mpdf = new mPDF('', 'A4', 0, '', 12, 12, 10, 10, 5, 5);
                        $style = base_url().'/source/template/css/stylesheet.css';
                        $stylesheet = file_get_contents( $style);
                        $CI->mpdf->WriteHTML($stylesheet,1);                       
                        $CI->mpdf->WriteHTML($htmView,2);                       
                        $CI->mpdf->Output('mpdf.pdf','I');
            }
}

我的控制器包含

function pdf()
    {
        $this->load->helper('pdfexport_helper.php');
        $urlid  = $this->uri->segment('3');
         if($urlid == "export") 
         {

             $data['pageTitle'] = "Annual Report";
             $data['htmView'] = $this->load->view('site_view',$data,TRUE);
             $templateView  = $this->load->view('../template_export',$data,TRUE);
             exportMeAsMPDF($templateView,$data['filename']);     

        }
    }

我的观点是

<html>
    <head>
        <title><?=$page_title?></title>
    </head>
    <body>
   <p align="right"> <a href="<?php echo base_url();?>index.php/site/pdf" style="text-align:right">Export to PDF</a></p>

     <table border="1">
        <?php foreach($result as $row):?>

        <tr>
       <td><a href=""><?=$row->id?></a></td>
        <td><p><?=$row->firstname?></p></td>
        <td><p><?=$row->lastname?></p></td>
        <td><p><?=$row->email?></p></td>
        <td><a href="<?php echo base_url();?>index.php/site/update">Update</a></td>
         <td><a href="">Delete</a></td>    

        <?php endforeach;?>
        </tr>
        </table>
    </body>
</html>

当我单击导出 pdf 时，它显示空白页面。

任何人都可以帮助我。在此先感谢。
