Question

controller：function pdf_question（）

htaccess

观点：

public function pdf_question()
{
    $data = [];
    $pdfFilePath = "output_pdf_name.pdf";
    $this->load->library('m_pdf');
    $this->m_pdf->pdf->WriteHTML($this->load->view('pdf-question'));
    $this->m_pdf->pdf->Output($pdfFilePath, "D");  
}

在这段代码中，我创建了一个名为pdf-question.php的视图文件，现在我想将这些问题导出为pdf formate，我正在使用mpdf codeigniter，我在第三方加载了M_pdf.php库和mpdf但它没有工作，它显示我的错误，即

那么，我该如何解决这个问题？请帮助我。

谢谢

Answer 1

对pdf_question函数进行简单的更改。

$html=$this->load->view('pdf-question', $data,true);
$this->m_pdf->pdf->WriteHTML($html);

Answer 2

自动加载集成后，您将在函数中使用Mpdf

        public function pdf_question(){
                $pdfFilePath = "output_pdf_name.pdf";
                $this->load->library('mpdf');
                $mpdf = new mPDF('bn', 'Legal');
                $mpdf->SetImportUse();
                $mpdf->AddPage('L');
                $html = $this->load->view('ViwewFileLocation', $data,true); 
                $mpdf->WriteHTML($html);
                $mpdf->Output($pdfFilePath, "D");
                 }

如何在codeigniter中使用mpdf？
