How do I make it so that the bars still draw correctly, but they don't draw from the code, they draw from $barcode. or how do I put the value of $barcode into there.........currently it has to be a 8 digit $barcode and I believe 4-5 random numbers either on front or back.  I want to be able to make $barcode have the value of an ean 13 barcode(which is how many numbers? 13 right?)  and so that that is the only thing dictating barcode(I do know how to make it more numbers, but I cant do that because of the 5 random ones).  does this make sense?

An EAN13 Bar-code is in fact 13 digits, BUT the last digit is a checksum, so only 12 digits are need to generate the bar-code,

As for what your attempting to do, it's quite unclear!

 

Bar-code are shouldn't contain "random number" and EAN13 has 12 usable digits, so that's a trillion bar-codes you can use!

let me try to explain this better then.  Basically, I need it just to be random digits, it isn't assigned to a product, it is going to be a piece in my database that will show up on a ticket, but right now, the last 4 numbers(besides for the extra) is being a random digit.  but 8 of them are what are in database.  I need to know how I can basically use a function that makes random numbers that I have print out all 12 digits(not the last) that can then use the barcode maker to make the bars.  how do I do this.  does this make more sense?

Erm... well

 

function getBarcodeNumber($barcode){
$barcode = (int)$barcode;
if(strlen($barcode) > 12) tigger_error('invalid barcode more that 12 digits supplied');
return str_pad($barcode , 12, "0", STR_PAD_LEFT);
}
$assetNo = 123;
$barcode = getBarcodeNumber($assetNo);
$pdf->EAN13(10, 120, $barcode);

I just need help as to where to put it in that code from before, I have this code, but I am pretty sure it isn't correct seeing as that I keep getting an error.  I can't get the error, because the server is down right now, but I bet it is probably pretty clear as to what it is......

//Page footer
function Footer()
{
    //Position at 1.5 cm from bottom
    $this->SetY(-15);
    //Arial italic 8
    $this->SetFont('Arial','B',;
    //Page number
    $this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');
}
}

//Instanciation of inherited class
$pdf=new PDF();
$pdf->AliasNbPages();
$pdf->AddPage();
$pdf->EAN13(10, 120, $barcode);
$pdf->SetFont('Arial','B',12);
$pdf->Output('ticket.pdf', 'I');
?> 
?> 

 

I am close to figuring it out, but now it cant find function EAN13
