Create product attribute programmatically in Magento

Create product attribute programmatically in Magento – In Magento, product is an EAV Model so to add a custom product attribute we need to create an EAV attribute. Before starting, make sure that you already prepared your own module. If you haven’t, you can create a simple module following this post.

In this tutorial, you need to to:
– edit your config.xml file
– create file /app/code/local/YourVendor/YourVendor/Model/Mysql4/Setup.php
– create file /app/code/local/YourVendor/YourModule/sql/yourmodule_setup/mysql4-install-1.0.0.php

Edit your config.xml file, add this content:

Create file /app/code/local/YourVendor/YourVendor/Model/Mysql4/Setup.php

with content:

Create file /app/code/local/YourVendor/YourModule/sql/yourmodule_setup/mysql4-install-1.0.0.php

with content:

In this file:
“1.0.0” is your module version which is declared in /etc/config.xml file.

To create a new product attribute, we will use function addAttribute of model eav/entity_setup. You can find that function in file /app/code/core/Mage/Eav/Model/Entity/Setup.php and this is the function:

 

After editing the file, if you already installed your module on your server before, you need to re-install in to execute mysql4-install-1.0.0.php file. You also can upgrade your module to higher version as 1.1.0 by editing config.xml file and rename file ‘mysql-install-1.0.0.php‘ to ‘mysql4-upgrade-1.0.0-1.1.0.php

To re-install your module, go to your phpmyadmin, find table core_resouce and delete row which has code ‘yourmodule_setup‘.

Finally, flush cache storage.

When everything is done, you could see your new product attribute in ‘Backend->Catalog->Attribute->Manage Attributes‘ search ‘new_product_attribute‘ for Attribute Code.
