is there a barcode program in PHP?
i just found a PHP bracode program on the net, but how can i use it? how will i start? any idea?
You are being very vague. What "barcode program" have you found? If we don't know what it is, how do you expect us to tell you how to use it? Have you even tried reading the provided documentation?
What exactly are you trying to do with barcode?
i got this PHP Barcode Image Generator v1.0 [9/28/2000] available at this link http://www.sid6581.net/cs/php-script...e/barcode.phps
how can i use this with a barcode reader? for example when the barcode reader reads a ceratin number it has its correspondent item.. how can i do that?
i am currently using a form for the user to input product,
but instead of inputting product i will use the barcode reader.
heres my form:
PHP Code:<?
session_start();
include("conn_db.php");
$call = mysql_query("SELECT invoice_no FROM cash_invoice");
while($row = mysql_fetch_array($call))
{
$invoice_no = $row["invoice_no"];
if($invoice_no==" ")
{
$invoice_no = 1;
}
else
{
$invoice_no = invoice_no + 1;
}
}
if(isset($_POST['save']))
{
include("insert_invoice.php");
}
?>

A barcode scanner simply acts as a keyboard. It will type exactly what the barcode says, and then simulate the return key. In order to read it, all you need is an input that keeps focus. Since it automatically simulates the return key, if you put it in a form, it will submit the form upon reading the barcode.
MOD what do you mean by "simulate the return key"? Is there no need for me to use the PHP Barcode Image Generator v1.0 program?
If you want to generate barcodes, then yes, you will need a generator. But, if you are just attempting to read them, then no.
