BARCODE Implementation in php

papsrockz · Aug 22, 2012

I am having a freaking out problem about how to implement barcode in a php web page.I want to embed barcode in my php project.After printing the web page in chrome it is displaying as barcode format but not scanning where as in mozilla it is returning the value itself.Any one having the solution please help me out.

I don't know what your issue is b/c I can't see any code or anything that you have attempted.....

I did however just finish a project working with code 128 and found this class by Mike Leigh to be very handy. It generates PNG's for the actual bar code and tested fine in WebKit, Gecko and Trident. It also printed fine and scanned well.

Maybe that class will help you as it did for myself.

I am posting here the code I have used....Can you please provide me the full code to implement barcode in php??? I want your assistance in this regard...

jeepin81 · Aug 23, 2012

Ummmmm nope! I cannot give you the full code. I did however give you the class I used. It's a good class and easy to use.

Here's sample of how I followed the instructions on how the class works:

//call class to generate code
include('code128.class.php');

echo "<h2>generate bar code</h2>";

$barcode = new phpCode128('whaaaaaat...scan me', 110, 'fonts/Arial.ttf', 12);
$barcode->setBorderWidth(0);
$barcode->setBorderSpacing(2);
$barcode->setPixelWidth(1);
$barcode->setEanStyle(false);
$barcode->setAutoAdjustFontSize(false);
$barcode->saveBarcode('barCodes/ImBarCode.png');

That should point you in the right direction.....

@: Sir I am also having the same problem regarding Barcode implementation in PHP..we r thankful to u coz u have helped us..but the problem is we dont write PHP5 codes,rather we write php4 code..so we cant understand where to use these class file and how to implement this in our project.we have got a code regarding BARCODE..i am posting the code..please tell me how to how to implement the following code in php4..

Due to some problem I am unable to post the entire code..I think the code we have is correct..just need ur help to implement this in proper way..Please help..

clever333 · Aug 13, 2013

I suggest you use a barcode generator or barcode font to do this. It would be very easy to add the barcode in PHP. You just need to add the third party control in the program and then do as the guide says.
