Magento - Adding Attributes programatically with default and searchable - magento

Question

I've searched everywhere for the answer, muddled through Magento and I can't find a working solution. I'm creating magento attributes dynamically and that's fine, but when it comes to
setting the values
setting the default value
adding more options
making the attribute searchable
nothing seems to work.
Here is my code for adding an attribute
$key = "Brand";
$name = "brand";
$specific = "Cola";
$installer->addAttribute('catalog_product', $name, array(
'type' => 'varchar',
'input' => 'select',
'backend' => '',
'frontend' => '',
'label' => $key,
'class' => '',
'source' => '',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'default' => '',
'searchable' => true,
'filterable' => true,
'comparable' => true,
'visible' => true,
'visible_on_front' => true,
'visible_in_advanced_search' => true,
'unique' => false,
'apply_to' => '',
'is_configurable' => false,
'option' => array(
'values' => array($specific)
)
));
$installer->endSetup();
$attrID = $installer->getAttribute('catalog_product', $name,'attribute_id');
$attr = Mage::getModel('eav/entity_attribute')->load($attrID);
$attr->setStoreLabels(array(1 => $key))->save();
It add's it fine, it even adds the option for me, but I can't seem to set that option as default (to add more later) and I can't make it searchable.
I really hope someone can help.
Thanks
Update:
Ok i've managed to get it adding the default (still not searchable etc) using this code.
$key = "Brand";
$name = "brand";
$specific = "Cola";
$installer->startSetup();
$installer->addAttribute('catalog_product', $name, array(
'type' => 'int',
'input' => 'select',
'backend' => '',
'frontend' => '',
'label' => $key,
'class' => '',
'source' => 'eav/entity_attribute_source_table',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
'visible' => true,
'required' => false,
'user_defined' => true,
'default' => '',
'searchable' => true,
'filterable' => true,
'comparable' => true,
'visible' => true,
'visible_on_front' => true,
'visible_in_advanced_search' => true,
'unique' => false,
'apply_to' => '',
'is_configurable' => false,
'option' => array(
'value' => array(
$this->getAttributeName($specific) => array($specific)
)
)
));
$installer->endSetup();
$attrID = $installer->getAttribute('catalog_product', $name,'attribute_id');
$attr = Mage::getModel('eav/entity_attribute')->load($attrID);
$attr->setStoreLabels(array(1 => $key));
$attr->setDefaultValue($attr->getSource()->getOptionId($this->getAttributeName($specific)));
$attr->save();
however when i go to add a new option using this code where $specific = "Pepsi";
$model = Mage::getModel('catalog/resource_eav_attribute');
$option = array();
$option['attribute_id'] = $attr;
$option['value'][$this->getAttributeName($specific)][1] = $specific;
$setup = new Mage_Eav_Model_Entity_Setup('core_setup');
$setup->addAttributeOption($option);
I get the error: "Default option value is not defined"

Answer 1

Did you have tried with 'is_searchable' => true instead of 'searchable' => true?

Answer 2

Look in to catalaog_eav_attribute. There is a column 'is_searchable' which type is smallint
Try this:
'is_searchable' => 1,

Answer 3

Referring to the error:
"Default option value is not defined"
When you add the option: ---------------------------------------> /
$option['value'][$this->getAttributeName($specific)][1] = $specific;
Here the [0] is the option's "default admin value" and [1] is the "default store value".
$option['value'][$this->getAttributeName($specific)][0] = $specific;
Your code is not making $specific the default option, but setting $specific the defaults store's value.
