2. Installation / Upgrade


Before uploading any file, enable Magento caches (System > Cache Management), this will prevent Magento from installing this extension as long as all files aren’t uploaded.

If you have any : APC cache, Memcache or Rediscache, please disable them.

Finally, make sure Magento’s compilation (System > Tools > Compilation) is disabled.


First, upload the extension file structure to your server on the same file structure provided by Magento :


Make sure all the files have been correctly transferred (Have a look at the tabs framed in black on the previous picture), you shouldn’t have any “Failed transfers”.


No code files will be erase by this extension.

All the extension’s code files will be available into app/code/community/MDN .

Once all files are uploaded, please follow these 2 steps to make sure it’s correctly installed:

  1. Refresh Magento caches (System > Cache Management).


If you get an error message at this stage, that means Barcode Label is not correctly installed.

Try to upload all extension files again.

  1. Logout and login yourself from Magento’s back office.

Barcode Label is now correctly installed.


If you want to disable the extension :

  1. Edit the file MDN_BarcodeLabel.xml in app/etc/modules.
  2. Replace True by False.
  3. Refresh caches (System > Cache Management).

Create barcode attribute

First, go to Catalog > Attributes > Manage Attributes and click on [Add new attribute]

When it’s done, click on [Save] and then go to Catalog > Attributes > Manage attributes sets

For each attribute set, drag and drop barcode attribute from Unassigned attributes to Groups list (in General directory)

Click on [Save], and then refresh your Magento indexes (System > Index Management)
