pretty sure I messed this up for the barcode can you help:

require('fpdf.php');

class PDF_EAN13 extends FPDF
{
function EAN13($x, $y, $barcode, $h=16, $w=.35)
{
    $this->Barcode($x,$y,$barcode,$h,$w,13);
}

function UPC_A($x, $y, $barcode, $h=16, $w=.35)
{
    $this->Barcode($x,$y,$barcode,$h,$w,12);
}

function GetCheckDigit($barcode)
{
    //Compute the check digit
    $sum=0;
    for($i=1;$i<=11;$i+=2)
        $sum+=3*$barcode[$i];
    for($i=0;$i<=10;$i+=2)
        $sum+=$barcode[$i];
    $r=$sum%10;
    if($r>0)
        $r=10-$r;
    return $r;
}

function TestCheckDigit($barcode)
{
    //Test validity of check digit
    $sum=0;
    for($i=1;$i<=11;$i+=2)
        $sum+=3*$barcode[$i];
    for($i=0;$i<=10;$i+=2)
        $sum+=$barcode[$i];
    return ($sum+$barcode[12])%10==0;
}

function Barcode($x, $y, $barcode, $h, $w, $len)
{
    //Padding
    $barcode=str_pad($barcode,$len-1,'0',STR_PAD_LEFT);
    if($len==12)
        $barcode='0'.$barcode;
    //Add or control the check digit
    if(strlen($barcode)==12)

Looks like the titles are stored in the database as title1, title2, ect.

 

Dose this not work:

 

<?php
      $sql = ("SELECT * FROM Events WHERE eventid='$eventid' && userid='$userid'");
$result = mysql_query($sql) or die(mysql_error());
while($row = mysql_fetch_array($result)){
$event = $row['event'];
$startdate = $row['startdate'];
$enddate = $row['enddate'];
$description = $row['description'];
$location = $row['location'];
$subevent1 = $row['title1'];
$subevent1 = $row['title2'];
$subevent3 = $row['title3'];
$subevent4 = $row['title4'];
$subevent5 = $row['title5'];
$subevent6 = $row['title6'];
}

if (!empty($subevent1)) { echo  "<br/>$subevent1"; }
if (!empty($subevent2)) { echo  "<hr><br/>$subevent2" ; }
if (!empty($subevent3)) { echo  "<hr><br/>$subevent3"; }
if (!empty($subevent4)) { echo  "<hr><br/>$subevent4"; }
if (!empty($subevent5)) { echo  "<hr><br/>$subevent5"; }
if (!empty($subevent6)) { echo  "<hr> <br/>$subevent6"; }
if (!empty($title7)) { echo  "<hr><br/>$title7"; }
if (!empty($title8)) { echo  "<hr><br/>$title8"; }
?>

The previous page stores it in the DB here:

 

$sql = "REPLACE INTO Events (name, event, eventid, userid, title1, title2, title3, title4, title5, title6, title7, title8, email, id, price1, price2, price3, price4, price5, price6, price7, price8) 
	VALUES('$name','$event','$eventid','$userid','$title1','$title2','$title3','$title4','$title5','$title6','$title7','$title8','$email','$id','$price1', '$price2', '$price3','$price4','$price5','$price6','$price7','$price8')";

 

So you should be able to just select it out of the DB on the next page.

 

For the barcode:

<?php
// code to popualte $total, ect. here.

class PDF extends FPDF

function EAN13($x, $y, $barcode, $h=16, $w=.35)
{

function UPC_A($x, $y, $barcode, $h=16, $w=.35)
{
    $this->Barcode($x,$y,$barcode,$h,$w,12);
}

function GetCheckDigit($barcode)
{
    //Compute the check digit
    $sum=0;
    for($i=1;$i<=11;$i+=2)
        $sum+=3*$barcode[$i];
    for($i=0;$i<=10;$i+=2)
        $sum+=$barcode[$i];
    $r=$sum%10;
    if($r>0)
        $r=10-$r;
    return $r;
}

function TestCheckDigit($barcode)
{
    //Test validity of check digit
    $sum=0;
    for($i=1;$i<=11;$i+=2)
        $sum+=3*$barcode[$i];
    for($i=0;$i<=10;$i+=2)
        $sum+=$barcode[$i];
    return ($sum+$barcode[12])%10==0;
}

function Barcode($x, $y, $barcode, $h, $w, $len)

    //Padding

ok, so with the barcode thing, how do I make it so that the 0 at start don't show up and the random number at end doesn't display.  will use a form to submit 13 numbers to database that is generated when the form is submitted and then I use those numbers to make the barcode, but I need to get rid of the 5(i believe) randomly generated numbers at beginning and end.  does this make sense?
