Very New to Codeigniter need help

#11
I don't know if the problem is still relevant.
First you have to download the domPdf folder in the libraries folder. Then you have to create a php class at the root of the libraries folder. Then you have to create a view that will receive the data to display in pdf. Then you create a function in the controller of your choice in which you call the model which will allow you to fetch your data in bdd to then transmit them to your view.

I put the minimum code for it to work.
To display the images in the view, you must not use the base_url () function of the url helper but use the php variable $ _SERVER ['DOCUMENT_ROOT']

This code works fine.

I am French so sorry if my English is not correct

/**
* your personal class which will instantiate the dompdf library
*/
<?php defined('BASEPATH') OR exit('No direct script access allowed');

require 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;

class Pdf extends Dompdf   
{
    public function __construct()
    {
        parent::__construct();
        $dompdf = new Dompdf();
    }
}
/**
* your fonction in the ctrl
*/
public function showBill($billID, $toDown)
    {
$billDatas = $this->bills_model->get($billID);
        $datas = array(
            'infos'        => "PDF bill creation",
            'title'        => "Bill - ".$this->config->item('appName'),
            'description'  => "PDF bill creation",
            'keywords'      => "Facture",
            'billDatas' => $billDatas
        );
// load your view in variable
        $pageHTML  = $this->load->view('billpdf', $datas, true);
        $fileName = $billDatas['beneficiaryDetails']['beneficiaryName']."-";
        $fileName = $fileName.$billDatas['beneficiaryDetails']['beneficiarySurname']."_";
        $fileName = $fileName.$billDatas['billInfos']['billRef']."_";
        $fileName = $fileName.$billDatas['billInfos']['billPeriod'];
        // load the dompdf library through your class
$this->load->library('pdf');
// load the view with dompdf
        $this->pdf->loadHtml($pageHTML);
// I put in comments what is optional
        // $customPaper = array(0,0,570,570);
        // $this->pdf->set_paper($customPaper);
        // $this->pdf->setPaper('A4','portrait');//landscape
        $this->pdf->render();
// il $toDown = 1 -> download file, if = 0 show in navigator
        $this->pdf->stream($fileName, array('Attachment' => $toDown));
}
