TCPDF/FPDF - Salto de página problema

Question

Estoy tratando de crear un archivo PDF con una tabla de datos .. Pero cuando se cumple un salto de página, salta a una nueva página cada vez que se agrega una nueva multicélula a la página en el romper nivel de punto ..!?

he tratado de hacer exactamente lo mismo con TCPDF, pero sigue siendo el mismo problema con un salto de página cada vez que una nueva célula he añadido alrededor del nivel de punto de salto de página ...

ejemplo:

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 $col_discount = 12;

$PDF = new File_PDF(); 
$PDF->generate(); 

Answer 1

el problema es que en el Cell() método (que se llama en MultiCell()) FPDF añade Allways una nueva página si el la corriente posición Y + la altura de la nueva célula es mayor que la allowe d altura de la página.

La altura de página predeterminada parece ser 297, con SetAutoPageBreak() resta de 150. Por lo tanto, cuando Y + cell_height tiene una graduación superior a 147, siempre obtendrá una nueva página cuando llame a su cnstr_cell().

Para evitar esto, necesita llamar al AddPage() por su cuenta. Añadir este cheque en su método de add_product():

$x = $this->width; 
$y = $this->pdf->GetY(); 

if (($y + $this->line_height) >= 147) { 
    $this->pdf->AddPage(); 
    $y = 0; // should be your top margin 
} 

BTW. También tuve que generar un PDF dinámico recientemente, terminé usando wkhtmltopdf, era mucho más fácil de usar y personalizar que todas las bibliotecas de PHP. Sugiero echarle un vistazo.
