php - 如何将多个 View 加载到 mpdf

Question

只是一个简短的问题。任何人都知道是否可以将多个 View 从 codeigniter 加载到 mpdf Controller 并将其转换为 pdf？我的 Controller :`

<?php

class C_Pdf extends CI_Controller {

private $params = array();

  function __construct() {
    parent::__construct();
    $this->params['set_tag'] = array();
    $this->params['set_css'] = array();
    $this->params['set_js'] = array();
    $this->params['title_auto'] = true;
    $this->params['title'] = '';
  }
public function index(){

//this data will be passed on to the view
$data['the_content']='mPDF and CodeIgniter are cool!';
$data['other']="siema heniu cos przeszlo";
//load the view, pass the variable and do not show it but "save" the output into $html variable
 $this->load->view('common/default_header',$this->params);
$html=$this->load->view('reservation/complete', $data,true);  
$this->load->view('common/default_footer');
//this the the PDF filename that user will get to download

//load mPDF library
$this->load->library('m_pdf');
//actually, you can pass mPDF parameter on this load() function
$pdf = $this->m_pdf->load();
//generate the PDF!
$pdf->WriteHTML($html);
//offer it to user via browser download! (The PDF won't be saved on your server HDD)
$pdf->Output();

}

}?>

我想从其他 View 添加页脚和页眉。

Answer 1

只需将页眉和页脚模板预取到变量中，然后将它们解析后的字符串传递给主视图，如下所示:

$data['header'] = $this->load->view('common/default_header',$this->params, true);
$data['footer'] = $this->load->view('common/default_footer', true);
$html = $this->load->view('reservation/complete', $data, true); 

注意第三个参数为true，这样您就可以在字符串中获取 View ，而不是将其发送到输出(最常见的是客户端浏览器)。

然后在您的主模板中，将 $header 和 $footer 变量放在您需要的任何位置。
