I have the following code where I am trying to change a 'color' attribute option label:


require_once 'app/Mage.php';


$attributeId = 92; // color

/** @var $attribute \Mage_Catalog_Model_Resource_Eav_Attribute */
$attribute = Mage::getModel('catalog/resource_eav_attribute');

// Register attribute for the easy use of the existing block
Mage::register('entity_attribute', $attribute);

// Use options tab from edit to easy get values    
/** @var $block \Mage_Adminhtml_Block_Catalog_Product_Attribute_Edit_Tab_Options */
$block = Mage::app()->getLayout()

// Get current labels, easy...

$label = $block->getLabelValues();

// Build options array

$options = array('value' => array());
foreach ($block->getOptionValues() as $optionValue) {
    $storeOption = array();
    foreach (Mage::app()->getStores() as $store) {
        $key = 'store' . $store->getId();
        $storeOption[$store->getId()] = $optionValue->$key;
    $options['value'][] = $storeOption;

// Show output


// Update value 0 for store 2

$options['value'][0][2] = 'New value';

// Update and save data



When I am launching the script, I get the following Fatal Error:

Fatal error: Uncaught exception 'Mage_Core_Exception' with message 'Default option value is not defined' in C:\xampp\htdocs\mag\app\Mage.php:595 Stack trace: #0 C:\xampp\htdocs\mag\app\code\core\Mage\Eav\Model\Resource\Entity\Attribute.php(353): Mage::throwException('Default option ...') #1 C:\xampp\htdocs\mag\app\code\core\Mage\Eav\Model\Resource\Entity\Attribute.php(198): Mage_Eav_Model_Resource_Entity_Attribute->_saveOption(Object(Mage_Catalog_Model_Resource_Eav_Attribute))

Does anyone know why?

Thanks a lot!


Here is how the var_dump() of the $options variable looks like:

array(1) {
  array(2) {
    array(6) {
      string(0) ""
      string(5) "GREEN"
      string(9) "New GREEN"
      string(5) "GRUEN"
      string(5) "VERDE"
      string(5) "VERDE"
    array(6) {
      string(0) ""
      string(4) "BLUE"
      string(4) "BLEU"
      string(4) "BLAU"
      string(3) "BLU"
      string(4) "AZUL"

The exception is thrown in the method Mage_Eav_Model_Resource_Entity_Attribute::_saveOption by this code:

if (!isset($values[0])) {
    Mage::throwException(Mage::helper('eav')->__('Default option value is not defined'));

This means that $values[0] is not set

$values comes from this code in the same method foreach ($option['value'] as $optionId => $values) {

Apparently in your code $options['value'][Some numeric key here][0] is not set. See how the $options array looks like before passing it to the setOption method (last line in your code).

  • Thanks a lot marius! $options['value'][Some numeric key here][0] was the admin value that I do not want to change. I want it to remain the same and only update the other options for each StoreView. – Supersonic Mar 4 '15 at 13:53
  • How do you set the $options['value'][Some numeric key here][0] to what it actually is in the Database? Many thanks! – Supersonic Mar 4 '15 at 14:01
  • How do you set the $options['value'][Some numeric key here][0] to what it actually is in the Database? Do you have to save it again in order to update the other ones? Thank you very much! Promiss, no more fishing ;-). – Supersonic Mar 4 '15 at 14:10
  • Post in your question how the $values var looks like. – Marius Mar 4 '15 at 14:19
  • both of your array elements are missing the 0 key. that's the option label for the admin store. You should try to replace this line foreach (Mage::app()->getStores() as $store) { with foreach (Mage::app()->getStores(true) as $store) { – Marius Mar 4 '15 at 15:01
