TCPDF/FPDF - Interruzione pagina

Question

Sto provando a creare un file PDF con una tabella di dati .. Ma quando viene soddisfatta un'interruzione di pagina, salta a una nuova pagina ogni volta che un nuovo multicell viene aggiunto alla pagina al punto di rottura ..!?

ho cercato di fare esattamente la stessa cosa con TCPDF, ma ancora lo stesso problema con un'interruzione di pagina ogni volta che una nuova cella ho aggiunto intorno al livello di punto di interruzione di pagina ...

esempio:

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; 
    private $col_vat = 12; 
    private $col_sum = 22;

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

Answer 1

il problema è che nel metodo Cell() (che è chiamato in MultiCell()) FPDF aggiunge allways una nuova pagina se la posizione attuale Y + l'altezza della nuova cella è maggiore del allowe d altezza della pagina.

L'altezza di pagina predefinita sembra essere 297, con SetAutoPageBreak() si sottrae 150 da esso. Quindi, quando Y + cell_height è più grave di 147, ricevi sempre una nuova pagina quando chiami il tuo cnstr_cell().

Per evitare questo è necessario chiamare da soli AddPage(). Aggiungere questo controllo nel metodo 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. Ho anche dovuto generare un PDF dinamico di recente, ho finito per usare wkhtmltopdf, era molto più facile da usare e personalizzare rispetto a tutte le librerie PHP. Suggerisco di dare un'occhiata a questo.
