Array and Class Construct Help, Please (newbie)

[Jezza22]

I have found a FPDF Class script that produces a basic invoice pdf document and I am trying to work out how to pass data to the LineItems() section. I believe that you achieve this through the public function __construct, but I am not sure how?

 

The data that I want to pass to LineItems also needs to be an Array, because I need to pass multiple lines to it.

 

So I neet to :-

 

1. How do I create an Array like the following: -

 

$data[] = array("Product Line 1", 1, 1750, 112.50, 862.50);
	$data[] = array("Product Line 2", 1, 750, 112.50, 862.50);

 

2. How can I pass this Array to the following Class: -

 

^{class InvoicePDF extends FPDF {}

 

 

 

^{private $PG_W = 190;}

 

^{public function __construct() {}

^{parent::__construct();}

^{$this->LineItems();}

 

^}

 

^{public function Header() {}

 

 

 

^{$this->SetFont('Arial', 'B', 16);}

^{$this->Cell($this->PG_W, 8, "True Track Software Ltd", 0, 0, 'C');}

^$this->Ln();

 

^{$this->Cell($this->PG_W, 5, "INVOICE", 0, 0, 'L');}

^{$this->Ln(10);}

 

^{$this->SetFont('Arial', 'B', 10);}

 

 

^{$this->Cell(165, 5, "Account:", 0, 0, 'R');}

^{$this->Cell(0, 5, "SHA001", 0, 0, 'R');}

 

^$this->Ln();

 

^{$this->Cell(165, 5, "Invoice No.:", 0, 0, 'R');}

^{$this->Cell(0, 5, "1", 0, 0, 'R');}

 

^$this->Ln();

 

^{$this->Cell(165, 5, "Date:", 0, 0, 'R');}

^{$this->Cell(0, 5, date("d/m/Y", time()), 0, 0, 'R');}

 

^{$this->Ln(10);}

^}

 

^{public function LineItems($value) {}

 

^{$header = array("Description", "Qty.", "Unit", "VAT", "Total");}

 

^{// Data}

 

 

^{$textWrap = str_repeat("This is a word wrap test ", 1);}

^{$textNoWrap = "There will be no wrapping here thank you";}

 

^{for($i = 0; $i < count($data); $i++) {}

^{$data[] = array("Product Line 1", 1, 1750, 112.50, 862.50);}

^{$data[] = array("Product Line 2", 1, 750, 112.50, 862.50);}

^}

^}

^{/* Layout */}

 

^{$this->SetDataFont('Arial', 'B', 12);}

^{$this->AddPage();}

 

^{// Headers and widths}

 

^{$w = array(85, 25, 20, 20, 20, 20);}

 

^{for($i = 0; $i < count($header); $i++) {}

^{$this->Cell($w[$i], 7, $header[$i], 1, 0, 'C');}

^}

 

^$this->Ln();

 

^{// Mark start coords}

 

^{$x = $this->GetX();}

^{$y = $this->GetY();}

^{$i = 0;}

 

^{foreach($data as $row)}

^{

^{$y1 = $this->GetY();}

^{$this->MultiCell($w[0], 6, $row[0], 'LRB');}

^{$y2 = $this->GetY();}

^{$yH = $y2 - $y1;}

 

^{$this->SetXY($x + $w[0], $this->GetY() - $yH);}

 

^{$this->Cell($w[1], $yH, $row[1], 'LRB');}

^{$this->Cell($w[2], $yH, number_format($row[2], 2), 'LRB', 0, 'R');}

^{$this->Cell($w[3], $yH, number_format($row[3], 2), 'LRB', 0, 'R');}

^{$this->Cell($w[4], $yH, number_format($row[4], 2), 'LRB', 0, 'R');}

 

 

^$this->Ln();

 

^$i++;

^}

 

^{$this->Ln(10);}

 

^{$this->setTextFont('Arial', 'B', 12);}

^{$this->Cell($w[0] + $w[1] + $w[3], 6, 'Total', 'TB', 0, 'L');}

^{$this->setDataFont(true);}

^{$this->Cell($w[2], 6, number_format(2, 2), 'TB', 0, 'R');}

^{$this->Cell($w[2], 6, number_format(2, 2), 'TB', 0, 'R');}

^{$this->Cell($w[2], 6, number_format(2, 2), 'TB', 0, 'R');}

^$this->Ln();

 

^{$this->setTextFont();}

 

^{$this->Write(10, "Notes: " . "Thank you for your business.");}

^{$this->Ln(10);}

^}

 

^{public function Footer() {}

 

^$this->Ln();

^{$this->Cell($this->PG_W, 5, "Payment Terms: " . "On Receipt", 0, 0, 'L');}

^{$this->Ln(10);}

^{$this->setTextFont(false);}

^$this->Ln();

^{$this->Cell($this->PG_W, 5, "Bank A/C No: 000000000", 0, 0, 'L');}

FPDF is written in PHP4 so it doesn't have __construct() method. It's constructor is in FPDF() method.

Ummm... I am sorry but I don't entirely get what you mean? The above Class works and produces a PDF document when I initialise the Object/Class and then use $pdf->output();

 

 

1. I am trying to work out how to assign a value to a property within a method LineItem()

2. Work out how to make the value that I want to assign to the method into an Array

 

The good news is I have worked number 2, I need to create a multi dimensional Array as follows: -

 

$data = array ( 	array($a1,$a2,$a3,$a4,$a5),
             array($a6,$a7,$a8,$a9,$a10),
                   ); 

 

This works and displays two lines on the PDF document. However I want to assign values to  $a1,$a2,$a3 etc outside of the Class????

 

I have an Index.php as follows that initialises the Class and creates the PDF document... Do I have do something in here...

 

define('FPDF_FONTPATH','font/');
require('fpdf.php');
require ('InvoicePDF.class.php');


$a1="ffefe";

$pdf = new InvoicePDF();


$pdf->Output();
