fpdf custom header - pippuccio76 - 05-01-2020

hi , sorry for english , i want extend fdpf ,  i create in library a new file :

PHP Code:
<?php

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

require ('fpdf/fpdf.php');

class PDF_print_a4 extends FPDF {

    private $intestazione;

    function __construct($orientation = 'P', $unit = 'mm', $size = 'A4',$intestazione) {
        parent::__construct($orientation, $unit, $size);
        $CI = & get_instance();
        $this->intestazione = $intestazione;
    }

    // Page header
    function Header()
    {    
        if($this->intestazione->logo!=''){

            $logo= './uploads/'.$_SESSION['user_id'].'/'.$intestazione->logo ;

        }else{


            $logo= './assets/assets_client/img/no_image.jpg';
        }

        // Logo
        $this->Image($logo,10,6,30);
        // Arial bold 15
        $this->SetFont('Arial','B',15);
        // Move to the right
        $this->Cell(80);
        // Title
        $this->Cell(30,10,'Title',1,0,'C');
        // Line break
        $this->Ln(20);
    }

    // Page footer
    function Footer()
    {
        // Position at 1.5 cm from bottom
        $this->SetY(-15);
        // Arial italic 8
        $this->SetFont('Arial','I',8);
        // Page number
        $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
    }    

    // Colored table
    function FancyTable($header, $data)
    {
        // Colors, line width and bold font
        $this->SetFillColor(255,0,0);
        $this->SetTextColor(255);
        $this->SetDrawColor(128,0,0);
        $this->SetLineWidth(.3);
        $this->SetFont('','B');
        // Header
        $w = array(40, 35, 40, 45);
        for($i=0;$i<count($header);$i++)
            $this->Cell($w[$i],7,$header[$i],1,0,'C',true);
        $this->Ln();
        // Color and font restoration
        $this->SetFillColor(224,235,255);
        $this->SetTextColor(0);
        $this->SetFont('');
        // Data
        $fill = false;
        foreach($data as $row)
        {
            $this->Cell($w[0],6,$row[0],'LR',0,'L',$fill);
            $this->Cell($w[1],6,$row[1],'LR',0,'L',$fill);
            $this->Cell($w[2],6,number_format($row[2]),'LR',0,'R',$fill);
            $this->Cell($w[3],6,number_format($row[3]),'LR',0,'R',$fill);
            $this->Ln();
            $fill = !$fill;
        }
        // Closing line
        $this->Cell(array_sum($w),0,'','T');
    }

} 

in my controller i call the library :

PHP Code:
      $this->load->library('PDF_print_a4');

      $intestazione =  $this->user_model->get_user($_SESSION['user_id']);

      $pdf = new PDF_print_a4('L','mm','a4',$intestazione);

      $pdf->AliasNbPages();
      $pdf->AddPage();

      $pdf->header();



      $pdf->output(); 


but i have this error :

Too few arguments to function PDF_print_a4::__construct(), 0 passed

Why ?

FWIW this constructor doesn't make sense. If 4th argument is mandatory, there is no point in specifying default values for arguments 1-3. You have to pass them anyway.
