Drawing a background image onto every page is straight out of example 51 in the documentation. We can add something similar to$img_file = $this->page % 2 ? 'recto.jpg' : 'verso.jpg';
to put a different background on odd and even pages.
Then it's just a case of adding a new page every time an even page is created. I've done this by extendingendPage()
which works a bit better with the final page than extendingstartPage()
.
You'll want to set some margins so that the text starts in the right place if it overruns the initial page.
class MyPDF extends TCPDF
{
public function Header()
{
// get the current page break margin
$bMargin = $this->getBreakMargin();
// get current auto-page-break mode
$auto_page_break = $this->AutoPageBreak;
// disable auto-page-break
$this->SetAutoPageBreak(false, 0);
// set background image
$img_file = $this->page % 2 ? 'recto.jpg' : 'verso.jpg';
$this->Image($img_file, 0, 0, 210, 297, '', '', '', false, 300, '', false, false, 0);
// restore auto-page-break status
$this->SetAutoPageBreak($auto_page_break, $bMargin);
// set the starting point for the page content
$this->setPageMark();
}
public function endPage($tocpage = false)
{
parent::endPage($tocpage);
if ($this->page % 2) {
$this->startPage();
$this->endPage();
}
}
}
