How to set default value with EAV AddAttribute
I want to set up a new attribute for my products in magento. This attribute must be a selection type from some parameters.
$installer->addAttribute('catalog_product', 'reserve', array(
'backend_label' => 'Attribute Reserve',
'type' => 'varchar',
'input' => 'select',
#'backend' => 'eav/entity_attribute_source_boolean',
'frontend' => '',
'source' => '',
#'default' => 1,
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'visible_in_advanced_search' => false,
'unique' => false,
'option' => array(
'value' => array(
'optionone' => array( 'O' ),
'optiontwo' => array( 'P' ),
'optionthree' => array( 'Kein Angabe' ),
)
),
));
How do I set the optionthree
default?

There was the same problem. My decision:
$installer->addAttribute('catalog_product', 'reserve', array(
'backend_label' => 'Attribute Reserve',
'type' => 'int',
'input' => 'select',
#'backend' => 'eav/entity_attribute_source_boolean',
'frontend' => '',
'source' => 'eav/entity_attribute_source_table',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'unique' => false,
'visible_in_advanced_search' => false,
'option' => array(
'value' => array(
'optionone' => array( 'O' ),
'optiontwo' => array( 'P' ),
'optionthree' => array( 'Kein Angabe' ),
)
),
));
Note the different type ( int
instead of varchar
) and source ( eav/entity_attribute_source_table
). This is how Magento represents typical selection attributes. Now you can set the default like this:
$model = Mage::getModel('eav/entity_attribute')
->load($installer->getAttributeId('catalog_product', 'reserve'));
$model
->setDefaultValue($model->getSource()->getOptionId('Keine Angabe'))
->save();

Please use this script: -
$installer->addAttribute('catalog_product', 'reserve', array(
'backend_label' => 'Attribute Reserve',
'type' => 'varchar',
'input' => 'select',
#'backend' => 'eav/entity_attribute_source_boolean',
'frontend' => '',
'source' => '',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'unique' => false,
'visible_in_advanced_search' => false,
'option' => array(
'value' => array(
'optionone' => array( 'O' ),
'optiontwo' => array( 'P' ),
'optionthree' => array( 'Kein Angabe' ),
)
),
/**
* This will set the default values,
* as "array" data type is being used to set proper default value
*/
'default' => array(
'optionthree'
),
));
Hope it helps.
