TCPDF and FPDI with multiple pages

Question

This looks like the simplest thing but I can't get it to work.

I need to add text to the first page of a multi-page pdf (could be any number of pages)

Using this code on a two page pdf (without the for loop, just using $pdf->importPage(2)) I end up with two pages but the second page is a repeat of page one. The text is written on the first page only which is good but I need all pages included in the output pdf. Here is my code

// Original file with multiple pages 
$fullPathToFile = 'full/path/to/file.pdf';

class PDF extends FPDI {

    var $_tplIdx;

    function Header() {

        global $fullPathToFile;

        if (is_null($this->_tplIdx)) {

            $this->setSourceFile($fullPathToFile);
            $this->_tplIdx = $this->importPage(1);

        }
        $this->useTemplate($this->_tplIdx);

    }

    function Footer() {}

}

// initiate PDF
$pdf = new PDF();
$pdf->setFontSubsetting(true);


// add a page
$pdf->AddPage();

// The new content
$pdf->SetFont("helvetica", "B", 14);
$pdf->Text(10,10,'Some text here');

// How to get the number of pages of original pdf???
// $numPages = $pdf->getNumPages(???);

// Carry on adding all remaining pages starting from page 2
for($i=2;$i<=$numPages;$i++) {
    // Add another page
    $pdf->AddPage();
    // Do I need to declare the source file here?
    // $pdf->setSourceFile($fullPathToWD);
    $pdf->importPage($i);
}

// Output the file as forced download
$pdf->Output('theNewFile.pdf', 'D');

Answer 1

Solved my problem...

// Original file with multiple pages 
$fullPathToFile = 'full/path/to/file.pdf';

class PDF extends FPDI {

    var $_tplIdx;

    function Header() {

        global $fullPathToFile;

        if (is_null($this->_tplIdx)) {

            // THIS IS WHERE YOU GET THE NUMBER OF PAGES
            $this->numPages = $this->setSourceFile($fullPathToFile);
            $this->_tplIdx = $this->importPage(1);

        }
        $this->useTemplate($this->_tplIdx);

    }

    function Footer() {}

}

// initiate PDF
$pdf = new PDF();
$pdf->setFontSubsetting(true);


// add a page
$pdf->AddPage();

// The new content
$pdf->SetFont("helvetica", "B", 14);
$pdf->Text(10,10,'Some text here');

// THIS PUTS THE REMAINDER OF THE PAGES IN
if($pdf->numPages>1) {
    for($i=2;$i<=$pdf->numPages;$i++) {
        $pdf->endPage();
        $pdf->_tplIdx = $pdf->importPage($i);
        $pdf->AddPage();
    }
}

// Output the file as forced download
$pdf->Output('theNewFile.pdf', 'D');

You get the number of pages by adding the first part of this line

$this->numPages = $this->setSourceFile($fullPathToFile);

And see the second last block of code - the for loop adds the remainder of the pages.

Don't know if this is how it should be done? I read in a few places that it wasn't even possible to achieve this, also the code is not supplied in the docs. However, this works, hope it helps someone.

You could also just have put the useTemplate in that for loop instead of extending the class, that would probably make the for loop more intuitive (i.e. get data (importPage), print data (useTemplate)). But good question/answer nevertheless, it inspired me to solve my own issue! – Stearns

Answer 2

I struggled with this a little and tried to come up with simplest way to add some text to the last page of a multi-page document. Here is the very simple code that worked for me:

require_once('fpdf/fpdf.php');
require_once('fpdf/fpdi.php');
$pdf = new FPDI();
$fullPathToPDF = '/usr/local/common/my.pdf';
$pageCount = $pdf->setSourceFile($fullPathToPDF);
for ($i = 1; $i <= $pageCount; $i++) {
    $pdf->importPage($i);
    $pdf->AddPage();
    $pdf->useTemplate($i);
}
$pdf->SetFont('Helvetica');
$pdf->SetXY(110, 225);
$pdf->Write(8, 'A complete document imported with FPDI');
$pdf->Output($fullPathToPDF);

Just change the full path to file to a location where you have a multi-page PDF.

Answer 3

$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);
...
$pdf->SetMargins(10, 10, 10);
$pdf->SetAutoPageBreak(true, 10);
foreach($array as $item)
{
  $pdf->AddPage(); //add new page for new item
  $txt = some_long_long_text;
  $pdf->Write(0, $txt, '', 0, 'C', true);
  $pdf->endPage(); //do end of page
  $pdf->lastPage(); //set cursor at last page, because autopagebreak not do it
}

In example, you have 10 pupils in array, and you need create resume for each. In exam, one resume have 3 pages. So in out u get pdf with 30 pages, with correct text. SetAutoPageBreak(true, 10), not set cursor at last page, so you need to do it manually with function $pdf->lastPage();

Answer 4

that code wont work, try this:

$pdf = new PDI();
$pdf->AddPage();
$pdf->setSourceFile('zzz.pdf');
$pdf->numPages = $pdf->setSourceFile('zzz.pdf');
$tplIdx = $pdf->importPage(1);
$pdf->useTemplate($tplIdx, 10, 20, 200);
    if($pdf->numPages>1) {
for($i=2;$i<=$pdf->numPages;$i++) {
    $pdf->AddPage();
    $tplIdx = $pdf->importPage($i);
    $pdf->useTemplate($tplIdx, 10, 20, 200);
}
}
