header and footer line in FPDI/TCPDF - php

Question

I'm stamping my PDF documents with FPDI and TCPDF functions, and I'm trying to figure it out, how can I add a line below the text in Header, and upon the text in footer. Here is my code:
<?php
require_once('lib/tcpdf/tcpdf.php');
require_once('fpdi.php');
$fullPathToFile = "TestClanek6.pdf";
class PDF extends FPDI {
var $_tplIdx;
function Header() {
global $fullPathToFile; //global
if(is_null($this->_tplIdx)) {
// number of pages
$this->numPages = $this->setSourceFile($fullPathToFile);
$this->_tplIdx = $this->importPage(1);
}
if($this->page > 0) {
//$this->SetPrintHeader(true);
$this->SetFont('times', 'I', 11);
$this->SetTextColor(0);
$this->Write(15, "Vol. 1, No. 15, Year: 2015, duff");
$this->Image('logo.png', 100, 2, 75,7);
} //end of IF
$this->useTemplate($this->_tplIdx, 0, 0,200);
} //end of HEADER
function Footer() {
if($this->page > 0) {
$this->SetY(-20);
$this->SetFont('times', 'I', 11);
$this->SetTextColor(0,0,0);
$this->Write(0, "Page", '', 0, 'C');
} //end of if
} // end of footer
} //end of CLASS
// new PDF file
$pdf = new PDF();
$pdf->addPage();
if($pdf->numPages>0) {
for($i=1;$i<=$pdf->numPages;$i++) {
$pdf->endPage();
$pdf->_tplIdx = $pdf->importPage($i);
$pdf->AddPage();
//$pdf->SetPrintHeader(false);
//$pdf->SetPrintFooter(false);
}
}
$file_time = time();
$pdf->Output("$file_time.pdf", "F");//, "I");
echo "Link: '<a href=$file_time.pdf>Stamped article</a>'";
?>
I've tried a lot of things like setPrintHeader(), etc. but nothing what I've found works for me. Could i please somebody to help?
Thank you.

Answer 1

You can use the Line method to draw a line in FPDF. If you want a straight horizontal line, just make sure the ordinates (y values) for the start and end of the line are the same. Something like this for example:
$pdf->Ln(15,$pdf->y,200,$pdf->y);
You would modify the values to suit your needs and insert it in the overridden methods for Header and Footer as appropriate for your application.

Answer 2

Better would be to leave the two methods (Header and Footer) empty. this way you would overwrite the drawing from super-class.
like this:
class EmptyFPDI extends FPDI
{
public function Header()
{
}
public function Footer()
{
}
}
