Error : - File doesnot begin with '%Pdf- '
I recommend avoid hidden input fields to parse variables. Better use the url itself when calling to action: action="printpdf.php?cname=XXXX". If the variable can be spoiled by the user, do one of three things: i)store the variable in server session: $_SESSION['cname']=XXXX; where it can't hardly be manipulated; ii)encode, hash or encrypt the url string; iii) sanitize the variable when recovering in the printpdf.php file. Hidden fields are easy to manipulate and are a primitive way of parsing data.
Try this way:
<?php
require('fpdf.php');
class PDF extends FPDF
{
function Header()
{
$this->Image('image.jpg',5,5,200);
$this->Ln(20);
}
//Page footer
function Footer()
{
$this->SetFont('Arial','I',8);
$this->Image('image1.jpeg',5,275,200);
$this->SetXY(5, 284);
$this->Cell(0,5,'This is a system generated ',0,2,'C');
$this->Cell(0,5,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}
//Instanciation of inherited class
if(isset($_POST['cname']))
{$c_n = $_POST['cname'];
$pdf=new PDF();
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->SetFont('Times','B',15);
$pdf->SetXY(5,42);
$pdf->Cell(190,10,'Challan', 0,0,'C');
$pdf->SetXY(5,52);
$pdf->SetFont('Times','B',12);
$pdf->Cell(150,18,'Name :-'.$c_n, 1,0,'L');
$pdf->Cell(15,0,$c_n, 0,0,'L');
$pdf->SetXY(155,52);
$pdf->Cell(50,9,'Challan No. :-', 1,2,'L');
$pdf->Cell(50,9,'Date :-', 1,0,'L');
$pdf->SetXY(5,70);
$pdf->Cell(15,15,'Sno', 1,0,'C');
$pdf->Cell(35,15,'Type', 1,0,'C');
$pdf->Cell(45,15,'Make', 1,0,'C');
$pdf->Cell(45,15,'Model', 1,0,'C');
$pdf->Cell(45,15,'Serial No.', 1,0,'C');
$pdf->Cell(15,15,'Qty', 1,0,'C');
$pdf->SetXY(5,85);
$pdf->SetFont('Times','',12);
$pdf->Cell(15,165,'', 1,0,'L');
$pdf->Cell(35,165,'', 1,0,'L');
$pdf->Cell(45,165,'', 1,0,'L');
$pdf->Cell(45,165,'', 1,0,'L');

I was also stuck at same point where i wanted to generate question paper with array of question and options.
Whatever you php code is, it must go before require('fpdf.php');
FPDF dont want any other code to come in between his code.
I hope, that solves the issue.
Error is here
$pdf->Cell(35,165,'', 1,0,'L');
$pdf->Cell(45,165,'', 1,0,'L');
$pdf->Cell(45,165,'', 1,0,'L');//*
$pdf->Cell(45,165,, 1,0,'L'); <<<<<<<<<<-----------------
$pdf->Cell(170,165,'', 1,0,'L');
$pdf->Cell(15,165,'', 1,0,'L');
$pdf->SetXY(5,245);
$pdf->SetFont('Times','B',12);
$pdf->Cell(35,20,'Reciever Name :- ', 0,0,'L');
$pdf->SetXY(125,245);
$pdf->Cell(35,20,'Reciever Signature :- ', 0,0,'L');
//*/
$pdf->Output();
change that line to $pdf->Cell(45,165,'', 1,0,'L');
put attention to your reference i.e. i use
$str = '../fpdf/fpdf.php';
require($str);
because there is where my code is an in images i.e. $this->Image($_SESSION['raiz'].'imagens/mmp.png',5,5,200); if you have your fpdf library and images in the same folder then all is right. by the way. i test the code correct error and it runs well
