Proprio come il titolo dice che ho problemi a combinare due classi. Anche se si tratta di FPDF, penso che questa sia una domanda regolare, dal momento che la domanda avrebbe potuto riguardare qualsiasi script.PHP: come combinare queste due classi?
Sto usando FPDF per creare documenti PDF al volo. Lo uso in combinazione con la classe FPDI per aggiungere immagini vettoriali al file PDF. La sceneggiatura può essere trovata qui sotto e funziona come un fascino.
<?php
// Add FPDF to generate PDF files
require_once('../fpdf16/fpdf.php');
// Add FPDI to add the functionality of importing PDF files for layout purposes
require_once('../fpdi131/fpdi.php');
// Code128 to create barcodes
require('code128.php');
// Function that extends FPDI to import a PDF file for layout purposes
class bezwaar extends FPDI
{
//Page header
function Header()
{
global $tplidx;
global $pagecount;
$this->SetFont('Arial','',8); // Font
if($this->PageNo()>1) $this->SetY(62); // Margins
$pagecount = $this->setSourceFile('standaardbezwaar.pdf'); // Open template
$tplidx = $this->importPage(1, '/MediaBox'); // Template import
$this->useTemplate($tplidx, 0, 0, 210); // Margins, Margins, Width.
}
}
#### General settings
$pdf = new bezwaar();
$pdf->AliasNbPages(); // Add headers
$pdf->SetTopMargin(34.7); // Margins top
$pdf->addPage(); // Open page
$pdf->SetFont('Arial','',8); // Set font
#### Content;
$pdf->MultiCell(0,4,$inhoud); // $inhoud is content from a database
$pdf->Output();
?>
Il problema è che vorrei aggiungere un'altra classe per aggiungere i codici a barre, ma non so come integrare questo. Lo script qui sotto funziona bene con FPDF, ma non con FPDI combinato.
<?php
$pdf=new PDF_Code128();
$code='CODE 128';
$pdf->Code128(50,20,$code,80,20);
$pdf->SetXY(50,45);
$pdf->Write(5,'A set: "'.$code.'"');
?>
Il problema è probabilmente perché ho bisogno di combinare questi due:
<?php
// I don't know how to combine the two below, especially not since both extend another class..
class bezwaar extends FPDI { } // Extends FPDI
class PDF_Code128 extends FPDF { } // Extends FPDF
// And/Or
$pdf = new PDF_Code128();
$pdf = new bezwaar();
?>

Domanda
Qualcuno potrebbe darmi una mano e dimmi come combinare entrambi gli script (sopra)? Io non sono nuovo in PHP, ma io sono nuovo con le classi, il che rende piuttosto difficile .. enter code here

Errore
Attenzione: Division by zero in /home/fpdf16/fpdf.php on line 812
Un altro tri al ed errore
Questo è ciò che di solito funziona, tranne questa volta. Sto aggiungendo le funzioni all'interno della classe codice a barre semplicemente nella classe FPDI estesa. Il risultato è che lo script va in timeout a meno che non abbia cancellato questa riga: $ pdf-> Code128 (50,20, $ code, 80,20), ma quella linea è indispensabile per creare il codice a barre. Qualcuno ha un'idea di dove potrebbe scadere?

io non comprendere appieno ciò che si sta cercando di raggiungere o cosa sta succedendo con il codice qui, ma può Basta passare l'output di 'PDF_Code128' a' bezwaar' come '$ pdf = new bezwaar ($ pdf);'. Quindi nel costruttore 'bezwaar' puoi avere pieno accesso all'output di' PDF_Code128'. – Treffynnon
