I'm not having much luck, creating barcodes on a HTML page
using:
<?php
require_once("/usr/local/lib/php/Image/Barcode/Code39.php");
$bc = new Image_Barcode;
$code = "123456789";
$bc->draw($code, "Code39", "jpg");
//$bc = new Image_Barcode_Code39('',2,4);
//$bc->draw('123456', 'jpg', false, 120);
?>
The last 2 lines give me nothing (hence commented out), the current code gives me I think the binary for the image:
 ě ÓJFIF ■>CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), default quality █C   $.' ",#(7),01444'9=82<.342 █C 2!!222222222222222222222222222222222222222 └2 ░
Etc:

Anyone got any ideas? or a better way of doing barcodes in php

Cheers
Jonathan

Your require_once call is wrong. You'll run sooner or later into problems with PEAR packages if you don't adjust your include_path setting.

Apart from this issue, I don't see the problem with your code? Are you aware that you need an <img> tag in your HTML page that references the PHP script in the "src" attribute?

The path is set by our hosting company but we are having a dedicated server build. I don't understand what you mean so could you explain about the path then I can tell our hosting company so they can get it right on our new server?

Also please could you give me a quick example of the img tag

Many thanks

Well, the include_path should include the PEAR directory, e.g.:
include_path = ".:/usr/share/pear/"

You can then shorten your require_once calls to e.g 'Image/Barcode.php' or 'HTML/QuickForm.php'.

<img src="your_barcode_script.php">, with your_barcode_script.php being the few lines of code that you've posted here.
