FPDI does not import specified number of pages

Question

I have a problem with FPDI/FPDF. I have a form that according to the chosen option (1, 2 or 3), either uses the source template for 1, 2 or 3 pages each.

$num_experiencias = $_POST["totalExpPdf"];

if($num_experiencias == "1"){
    $pdf->setSourceFile(dirname(dirname(__FILE__)) .'/pdfs/guia_uno_blanco.pdf'); // one blank page             
} else if($num_experiencias == "2"){
    $pdf->setSourceFile(dirname(dirname(__FILE__)) .'/pdfs/guia_dos_blanco.pdf'); // two blank pages
} else{
    $pdf->setSourceFile(dirname(dirname(__FILE__)) .'/pdfs/guia_tres_blanco.pdf'); // three blank pages
}

So if $num_experiencias is 1, I write something in the pdf and likewise I write other stuff if the number is 2 or 3.

// ******** PAGE 1 ********
$pageId = $pdf->ImportPage(1);
$pdf->AddPage();
$pdf->useTemplate($pageId, null, null, 0, 0, true); 

// IMAGE
$pdf->Image($imagen1,10,10,234,170);

// NUM EXP
$pdf->SetXY(30, 35);
$pdf->SetFont('Quicksand-Regular', '', 16);
$pdf->SetTextColor(255, 255, 255);
$pdf->MultiCell(50, 13, utf8_decode('Experiencia 1/'.$num_experiencias), 0, 'C');

// ******** PAGE 2 ********
 if ($num_experiencias >= "2"){
    $pageId = $pdf->ImportPage(2);
    $pdf->AddPage();
    $pdf->useTemplate($pageId, null, null, 0, 0, true); 

    // IMAGE
    $pdf->Image($imagen2,10,10,234,170);
}

// ******** PAGE 3 ********
if($num_experiencias == "3"){
    $pageId = $pdf->ImportPage(3);
    $pdf->AddPage();
    $pdf->useTemplate($pageId, null, null, 0, 0, true); 

    // IMAGE
    $pdf->Image($imagen3,10,10,234,170);
}

The problem is that if I want only 1 page ($num_experiencias == 1), the output pdf is 6 pages long (instead of 1). If $num_experiencias is 2, the pdf is now 12 pages long (when it should be 2) and if $num_experiencias is 3, the pdf is now 18 pages long (when it should be 3). What's going on? O.o

Your code seems to trigger automatic page breaks.

If you set the font color to something other than white you should see which items are triggering this.

To disable it just call

$pdf->SetAutoPageBreak(false);

before you write any content to the page/document.
