TCPDF / FPDF - page break problem

I am trying to create a PDF file with a data table. But when a page break is performed, it jumps to a new page every time a new page is added to the page at the breakpoint level ..!?

I tried to do the same with TCPDF, but still the same question with page break every time a new cell I added around the level of the page break point ...

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

The problem is that in the Cell() method (which is called in MultiCell() ) FPDF always adds a new page if the current position Y + the height of the new cell is greater than the allowed page height.

By default, the page height is 297, and SetAutoPageBreak() you extract 150 from it. Therefore, when Y + cell_height is more than 147, you always get a new page when you call cnstr_cell() .

To prevent this, you need to call AddPage() yourself. Add this check to 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 dynamic PDF recently, I ended up using wkhtmltopdf , it was easier to use and configure than all PHP libraries. I suggest taking a look at it.
