Magento loadByAttribute for Custom Category Attributes
- by Chris
I have created custom attributes for a category in my module's install script like so:
$attrib = array(
'type' => 'varchar',
'group' => 'My Data',
'backend' => '',
'frontend' => '',
'label' => 'My Custom Field',
'input' => 'text',
'class' => '',
'source' => '',
'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_STORE,
'visible' => true,
'required' => false,
'user_defined' => false,
'default' => '',
'searchable' => false,
'filterable' => false,
'comparable' => false,
'visible_on_front' => false,
'unique' => true,
);
$installer->addAttribute(3, 'custom_field', $attrib);
The field shows up fine in the admin, and when I create the category in my script like so:
$p_category = Mage::getModel('catalog/category')
->setStoreId(0)
->load(2);
$category = Mage::getModel('catalog/category');
$category->setStoreId(0)
->setName('Test Category')
->setCustomField('abcd')
->setDisplayMode('PRODUCTS')
->setAttributeSetId($category->getDefaultAttributeSetId())
->setIsActive(1)
->setIsAnchor(1)
->setPath(implode('/',$p_category->getPathIds()))
->setInitialSetupFlag(true)
->save();
I can see the value 'abcd' in the Magneto admin interface. But when I call the code below:
<?php
$category = Mage::getModel('catalog/category')->loadByAttribute('custom_field', 'abcd');
print_r($category);
?>
I get no result. But if I loadByAttribute using the 'name' field set to 'Test Category', I DO get a result.
So, in the database, I looked into the catalog_category_entity_varchar table and noticed that the 'name' attribute had an entry for both store_id = 0 AND store_id = 1 whereas the 'custom_field' attribute had only an entry for store_id = 1.
When I added a store_id = 0 entry for 'custom_field' with the value set to 'abcd' in the catalog_category_entity_varchar table, loadByAttribute got the expected result.
My question is, why is the 'name' field getting a store_id = 0 entry in catalog_category_entity_varchar and my custom field is not?
How do I load categories by custom attributes?
