How to delete blank page in mPdf - php

Question

I am converting an html file to PDF by using mPdf, but the returned PDF file includes blank pages. I want to delete those blank pages.

Answer 1

Had the same problem and realized that my CSS was forcing these page breaks. Make sure you don't have this in your CSS:
page-break-after: always;

Answer 2

It may be for many reasons:
1) Make sure the elements doesn't have unnecessary margins nor Paddings
2) Configure correctly the page properties (specially margins) :
$page_orientation = 0;
$page_size = 'Letter';
$page_margins = array('LEFT(int)','RIGHT(int)','UP(int)','BOTTOM(int)');
$pdf_output = 'I';
$css_files = array(
'path/file.css',
'path/file_2.css',
);
$orientationPage = array('','-L');
/* ===== [ MPDF ] =====*/
$mpdf=new mPDF('utf-8', $page_size.$orientationPage[$page_orientation],'','',$page_margins[0],$page_margins[1],$page_margins[2],$page_margins[3]);
// Loading CSS
for($i = 0; $i < count($css_files); $i++){
$stylesheet = file_get_contents('../../'.$css_files[$i]);
$mpdf->WriteHTML($stylesheet,1); // 1 para indicar que es CSS
}
// Set header & Footer (This are variables with html code)
$mpdf->SetHTMLHeader($header);
$mpdf->SetHTMLFooter($footer);
$mpdf->SetDisplayMode('fullpage');
$mpdf->SetTitle($title);
$mpdf->WriteHTML($html); // <-- insert HTML
// Create PDF
$mpdf->Output($titulo.'.pdf',$pdf_output);
3) Make sure you haven't unnecessary "Page Breaks" on the HTML
<pagebreak type="NEXT-ODD" resetpagenum="1" pagenumstyle="i" suppress="off" />
I hope it can help you!

I had the same problem and i fixed it by removing the AddPage property from my code
I changed the following code
// Code with bug
$mpdf = new mPDF('utf-8', array(380,500));
$mpdf->WriteHTML($htmlContent);
$mpdf->AddPage('P'); // It will add extra page - I that i removed this line
$mpdf->Output();
Into this
// code after resolving the bug
$mpdf = new mPDF('utf-8', array(380,500));
$mpdf->WriteHTML($htmlContent);
$mpdf->Output();
