在这段代码中，我创建了一个名称为income_reports.php的视图文件，现在我想将这些问题导出为pdf格式，为此我使用的是mpdf CodeIgniter，其中我已加载了{ {1}}第三方库和pdf，但无法正常工作，它显示了一个错误。

那么，如何解决此问题？请帮助我。

错误：1）

遇到PHP错误严重程度：注意消息：未定义的属性：m_pdf :: $ pdf 文件名：controllers / Home.php 行号：156

2）

遇到未捕获的异常类型：错误消息：在null上调用成员函数WriteHTML（）文件名：C：\ xampp \ htdocs \ income_expence_manage \ application \ controllers \ Home.php 行号：156

谢谢

尝试一下：

1.application / libraries / M_pdf.php：

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class M_pdf {

    function m_pdf()
    {
        $CI = & get_instance();
        log_message('Debug', 'mPDF class is loaded.');
    }

    function load($param=NULL)
    {
        include_once APPPATH.'/third_party/mpdf/mpdf.php';

        if ($params == NULL)
        {
            $param = '"en-GB-x","A4","","",10,10,10,10,6,3';                
        }

        //return new mPDF($param);
        return new mPDF();
    }
}
?>

2。将mpdf文件夹复制到application / third_party /

3.Controller：

$html = $this->load->view('filename',$data,true);
$pdfFilePath = 'path/filename';
$pdf = $this->m_pdf->load();
$pdf->AddPage('','','','','',5,5,5,5,10,10); //set margin
$pdf->WriteHTML($html,2);
ob_clean();
$pdf->Output($pdfFilePath, "F");

在codeigniter中将HTML转换为pdf
