FPDI, FPDF SetAutoPageBreak add template to page after break - php

Question

I've created a form that allows users to create a pdf that has an unlimited number of pages, I've got SetAutoPageBreak set so that it continues onto a second page however I cannot get the pages created after the page break to continue to use the original template file. The basic code can be seen below.
require('fpdf.php');
require('fpdi.php');
$pdf = new FPDI('P','mm','A4');
$pageCount = $pdf->setSourceFile("source_file.pdf");
$tplIdx = $pdf->importPage(1);
$pdf->AddPage();
$pdf->useTemplate($tplIdx);
$pdf->SetTextColor(63,76,89);
$pdf->SetMargins(5,39,5,20);
$pdf->SetAutoPageBreak(true,22); //page created doesn't have template attached
$pdf->SetDrawColor(225,225,225);
$pdf->SetFillColor(248,248,248);
$pdf->SetLineWidth(1);
$pdf->SetXY(82, 40);
$pdf->MultiCell(165,5,$company.$block,0,L,false);
$pdf->SetXY(19, 45);
$pdf->MultiCell(165,5,$date.$block,0,L,false);
$pdf->Output();
Having looked around, this question is the closest I can find however I'm not sure whether it is even relevant: FPDF/FPDI UseTemplate
Thanks

Answer 1

Just place the imported page in the Header method:
class PDF extends FPDI
{
protected $_tplIdx;
public function Header()
{
if (null === $this->_tplIdx) {
$this->_tplIdx = $this->importPage(1);
}
$this->useTemplate($this->_tplIdx);
}
}
$pdf = new PDF('P','mm','A4');
$pdf->AddPage();
...
...and everything should work as expected.

in addition to #JanSlabon`s answer: (i dont have the needed reputation to write a comment, so i´ll post this here, hope that´s ok)
If you only want to use a certain template for the first page and a different one for all other pages, you can do so as follows:
class PDF extends FPDI
{
protected $_tplIdx;
public function Header()
{
if (null === $this->_tplIdx) {
$this->setSourceFile('paper1.pdf');
$this->_tplIdx = $this->importPage(1);
} else {
$this->setSourceFile('paper2.pdf');
$this->_tplIdx = $this->importPage(1);
}
$this->useTemplate($this->_tplIdx);
}
}
i know its not exactly what #Searlee was looking for, but maybe it helps someone else.
