TCPDF / FPDF - Page break issue
The problem is that in the Cell()
method (which is called in MultiCell()
) FPDF allways adds a new page if the the current Y position + the height of the new cell is greater than the allowed page height.
The default page height seems to be 297, with SetAutoPageBreak()
you substract 150
from it. So when Y
+ cell_height
is graeter than 147 you allways get a new page when calling your cnstr_cell()
.
To prevent this you need to call AddPage()
by yourself. Add this check in your add_product()
method:
$x = $this->width;
$y = $this->pdf->GetY();
if (($y + $this->line_height) >= 147) {
$this->pdf->AddPage();
$y = 0; // should be your top margin
}
Btw. I also had to generate a dynamic PDF recently, I ended up using wkhtmltopdf, it was way more easy to use and customize than all the PHP libraries. I suggest to take a look at it.

I'm trying to create a PDF file with a table of data.. But when a page break is met it jumps to a new page everytime a new multicell is added to the page at the break point level..!?
I have tried to do exactly the same with TCPDF, but still the same issue with a page break each time a new cell i added around the page break point level...
example:
http://www.online-økonomi.dk/_tst_fpdf.php
require_once '../class/download/fpdf/fpdf.php'; class File_PDF { private $pdf; private $col_product = 25; private $col_unit = 12; private $col_price = 20; private $col_count = 14; private
