First of all, we have to create a module for adding custom category attribute.
Step 1. Create a new module.
We should let Magento know about our new module. The initial configuration file is located at ‘app/etc/modules/Namespace_Modulename.xml’.
Namespace_Modulename.xml
|
1 2 3 4 5 6 7 8 9 |
<?xml version="1.0"?> <config> <modules> <Namespace_Modulename> <active>true</active> <codePool>local</codePool> </Namespace_Modulename> </modules> </config> |
Step 2.
Module configuration file is located at ‘app/code/<code_pool>/<name_space>/<module_name>/etc’ and its name is config.xml – so this path looks like ‘app/code/local/Namespace/Modulename/etc/config.xml’.

<?xml version="1.0"?> <config> <modules> <Namespace_Modulename> <version>1.0.0</version> </Namespace_Modulename> </modules> <global> <resources> <add_category_attribute> <setup> <module>Namespace_Modulename</module> <class>Mage_Catalog_Model_Resource_Setup</class> </setup> <connection> <use>core_setup</use> </connection> </add_category_attribute> <add_category_attribute_write> <connection> <use>core_write</use> </connection> </add_category_attribute_write> <add_category_attribute_read> <connection> <use>core_read</use> </connection> </add_category_attribute_read> </resources> </global> </config> |
<add_category_attribute> presence that script must be located in the folder with the same name. ‘app/code/local/Namespace/Modulename/sql/add_category_attribute’
Step 3.
Create and install a script file in the folder ‘add_category_attribute’, and the file name depends on the module version.
