Answer 2

I have done pdf generation with tcpdf library but with a slightly different approach from you. Here is my solution with tcpdf. You can try it with Dompdf.

Download tcpdf and put in third_party folder Make a file PDF.php in libraries folder with the following contents

 require_once APPPATH."third_party/tcpdf/tcpdf.php";

    class PDF extends TCPDF {
        public function __construct() {
            parent::__construct();
        }
    }

In controllers folder create a file Createpdf.php with following codes

defined("BASEPATH") OR exit("No direct script access allowed");

    class Createpdf extends CI_Controller {

        public function pdf()
        {
            $this->load->library("pdf");
            $data["content"] = "Hello from CodeIgniter with TCPDF...";
            $this->load->view("pdfreport", $data);
        }
    }

and the pdfreport.php view is:

$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->AddPage();
$obj_pdf->writeHTML($content, true, false, true, false, '');
$obj_pdf->Output('output.pdf', 'I');

Answer 3

First install it by composer

composer require dompdf/dompdf

And use this in pdf library .

 require 'vendor/autoload.php';
 use Dompdf\Dompdf as Dompdf;

Answer 4

Starting with v0.7.0 Dompdf uses namespaces. You probably need to add a use statement prior to referencing the class. Or reference it using the full namespace path.

Try:

require_once(dirname(__FILE__) . '/dompdf/autoload.inc.php');
use Dompdf\Dompdf;
class Pdf extends Dompdf
{
...
}

Usage is available in the readme or on the wiki usage page.
