Implements entity-attribute-value pattern and provides a simple way to work with EAV-attributes. EAV-attributes are stored in the database as separate records but accessed and searched in such a way as if they were columns in the entity's table.

The following features are supported:

  • Eager and lazy loading of EAV-attributes.
  • Dynamic validation rules. The validation rules defined for the EAV-attribute will be added to the model dynamically.
  • Automatically inserting/updating/deleting EAV-attribute values.
  • Accessing and editing EAV-attributes in the same way as if they were real attributes of the model.
  • A simple search by EAV-attributes with using the find methods.


  • Yii 1.1.2 or above
  • PHP 5.1 or above


  1. Download and extract the release files under the folder "protected/components/eavactiverecord".
  2. Run the SQL-script mysql.sql or postgresql.sql (if your DBMS is PostgreSQL) It is located in the following folder: "protected/components/eavactiverecord/schema/". It creates tables needed to work with EAV attributes: eav_set, eav_attribute, eav_attribute_set, eav_attribute_date, eav_attribute_int, eav_attribute_varchar, eav_attribute_text.
  3. Add the following lines in the file "protected/config/main.php": ~~~ [php] array( 'import' => array( 'application.components.eavactiverecord.', 'application.components.eavactiverecord.datatypes.', 'application.components.eavactiverecord.helpers.*', ) ~~~

  4. It requires cache to be activated in the application: ~~~ [php] array( … 'components'=>array(

             array('host'=>'server1', 'port'=>11211, 'weight'=>60),
             array('host'=>'server2', 'port'=>11211, 'weight'=>40),

    ), ); ~~~ The extension will use own cache component if it is defined as the following: ~~~ [php] array( … 'components'=>array(

             array('host'=>'server1', 'port'=>11211, 'weight'=>60),
             array('host'=>'server2', 'port'=>11211, 'weight'=>40),

    ), ); ~~~ If you do not use cache, add the following code in the file "protected/config/main.php": ~~~ [php] 'components' => array(

     'eavCache' => array(
         'class' => 'system.caching.CDummyCache'

    ) ~~~

  5. Extend your model class from the class EavActiveRecord ~~~ [php] class Foo extends EavActiveRecord ~~~

  6. Call the method Foo::addColumn(). This method must only be called once for each model that extends EavActiveRecord class. It adds the new column "eav_set_id" in the associated database table. ~~~ [php] Foo::model()->addColumn(); ~~~

  7. Since v1.0.2 it includes the GUI module for user interaction (front-end module) based on the extension API. For detailed information about installing the module, reed the EavModule Installation Guide
