Question

当我使用MPDF下载pdf文件时，我收到此错误。我在下面加载代码：

    $html = $this->load->view('customer/case_report',$this->data, true);
    $pdfFilePath = "output_pdf_name.pdf";
    $this->load->library('M_pdf');
    $this->M_pdf->pdf->WriteHTML($html);
    $this->M_pdf->pdf->Output('CaseReport_CaseNo_'.$caseNo.'.pdf', 'D');

更新在此处附加屏幕截图：

任何帮助将不胜感激。谢谢

Answer 1

好吧我已经模拟了案例，工作内容如下

从mPDF Library using Codeigniter下载图书馆

将其放在application / third_party中。在application / libraries中创建了一个文件M_pdf.php

<?php
  if (!defined('BASEPATH')) exit('No direct script access allowed');
  include_once APPPATH.'/third_party/mpdf/mpdf.php';

  class M_pdf {

    public $param;
    public $pdf;
    public function __construct($param = "'c', 'A4-L'")
    {
      $this->param =$param;
      $this->pdf = new mPDF($this->param);
    }
 }
?>

在My Controller中创建一个Test功能进行测试。起初我试图保存它并得到像

这样的错误

然后我将输出中的F开关替换为D进行下载

public function mdfTest()
{
  $pdfFilePath = time()."_order.pdf";
  $this->load->library('M_pdf');
  $html="<html><h1>This is test pdf</h1></html>";
  $this->m_pdf->pdf->WriteHTML($html);

  //download it.
  $this->m_pdf->pdf->Output($pdfFilePath, "D");

}

它有效。创建了一个像

这样的PDF文件

Answer 2

文件名：libraries / M_pdf.php
文件夹名称：third_party / mpdf

include_once APPPATH。＆＃39; /third_party/mpdf/mpdf.php' ;;

类M_pdf {

public $param;
public $pdf;

public function __construct($param = '"en-GB-x","A4","","",10,10,10,10,6,3')
{
    $this->param =$param;
    $this->pdf = new mPDF($this->param);
}

}

控制器文件

    public function pdf_create()
    {
        $this->load->library('M_pdf');
        $pdffile = time()."_order.pdf";
        $this->m_pdf->pdf->WriteHTML("My First Codeigniter in First Pdf 
        Create.");
        $this->m_pdf->pdf->Output($pdffile, "I");
    }
