Multiselect attributes can be set as a comma separated list (or also an array) containing the attribute value ids.
So first we have to convert the actual values to Magento's internal ids.
$attrCode = 'color_base'; $sourceModel = Mage::getModel('catalog/product')->getResource() ->getAttribute($attrCode)->getSource(); $valuesText = explode(',', 'red,green,blue'); $valuesIds = array_map(array($sourceModel, 'getOptionId'), $valuesText); $product->setData($attrCode, $valuesIds); $product->save(); - this is not working, the page is keep on loading with this codeNetorica– Netorica2013-11-25 06:34:36 +00:00Commented Nov 25, 2013 at 6:34
Modify last line of the above code
$product->save(); with
$product->getResource()->saveAttribute($product, $attrCode); It works
$attrCode = 'color_base'; $sourceModel = Mage::getModel('catalog/product')->getResource() ->getAttribute($attrCode)->getSource(); $valuesText = explode(',', 'red,green,blue'); $valuesIds = array_map(array($sourceModel, 'getOptionId'), $valuesText); $OptionIds = implode(',', $valuesIds); $product->setColorBase($attrCode, $OptionIds); $product->getResource()->saveAttribute($product, 'color_base');
