控制器:功能pdf_question()如何在codeigniter中使用mpdf?

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"); 
} 

觀點:

<html> 
<head> 
</head> 
<body> 
    <div class="container"> 
     <div class="col-lg-12" style="background:#38558a;"> 
      <h3 style="color:#ff7900;"><b>Quiz Questions</b></h3> 
      <hr> 
     </div> 
     <div class="row"> 
      <div class="col-md-12"> 
      <br/> 
       <div class="login-panel panel panel-default"> 
        <div class="panel-body"> 
         <a href="javascript:void(0)" class="btn btn-danger" style="float:right;" id="pdf">PDF</a> 
         <div class="col-lg-12" id="target"> 
          <?php 
           $this->db->select('*'); 
           $this->db->from('qbank'); 
           $query = $this->db->get(); 
           $result = $query->result_array(); 
           foreach($result as $row) 
           { 
            $qid = $row['qid']; 
            $question = $row['question']; 
          ?> 
            <div class="col-div-container">

在您的pdf_question函數中做一個簡單的修改。

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