Generate and Download PDF file in Codeigniter

After a long time, I am writing a new article. Thanks for everyone's support. Today we are going to see How to create and download PDF files by using CodeIgniter mPDF library. mPDF is a customized third-party library, using this simple library function we will convert our HTML template code to PDF. Follow the below step by step process.

Live Demo            Download Script 

Step 1: Download the latest version of mPDF library files. Load the files in your third-party (new directory)  or library folder.

Path: application\third_party\


Step 2: Create a new file in your library (mpdf.php) and paste the below code.
path: application\ibraries\

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

Step 3: Create a new controller or use your existing controller to load the below function,

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
 
class Welcome extends CI_Controller {
 
 
 public function index()
 {
  $html=$this->load->view('mypdfLayout',"", true); // html file
  $pdfFilename = "myfilename.pdf";
  $this->load->library('m_pdf');
  $this->m_pdf->pdf->WriteHTML($html);
  $this->m_pdf->pdf->Output($pdfFilename, "D");  
 }
}

Step 4: Create an HTML template and load in your view folder.
