Following on from my post about mass exporting Magento data, I had the requirement to also mass generate EAN13 barcodes from scratch for all Magento products in a store.

The barcode graphic functionality came courtesy of Folke Ashberg and I simply added the functionality to my basic export php script.

The script creates the EAN code and checksum (currently programmed for EAN13) using the a 5 digit product number derived from the Magento product id and your registered manufacturer code. The barcode image is generated on the fly and cached locally.

My requirement was to generate the EAN code and not the barcode image so I am not 100% if the image is to the EAN standard, I think the font may need to be changed, however if you require EAN numbers and images, e.g. for Amazon etc. then this is a good place to start!

Magento EAN Generator

You can download a standalone version of my Magento EAN Generator from GitHub here. Install the code in a web accessible folder, or in your Magento installation folder. Open the application config file and configure the correct path to your Magento installation. Also configure your EAN prefix code.

Run the script by browsing to http://www.yoursite/eaninstallfolder/ean.php?export, this will generate a delimited txt file containing SKU and EAN13 code for all visible products in your store.

Or run the script from the command line using

php php.ean debug

< MAGENTO EAN -> D E B U G >

You can see an example of the scripts output here.

You might want to validate the generated EAN codes, specifically to validate the 13th checksum code, do this here.
