Loading a product collection by a specific attribute drop-down value

Question
I am trying to load a specific virtual products with its custom options, but instead I keep getting an empty array.
My attribute is 'part_identifier' in the attribute set 'boat_part' It is a drop-down type attribute with several options. The option I am trying to pull by is 'Look'.
Here is my code:
$attribute = 'msh_boat_part_identifier';
$boatLookProducts = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('*')
->addAttributeToFilter($attribute, array('like'=>'Look'))
->load()
->getItems();
foreach($boatLookProducts as $boatLookProduct)
{
$return[] = array(
"id" => (int)$boatLookProduct->getEntityId(),
"name" => $boatLookProduct->getName(),
"type" => "profile",
"shortDesc" => $boatLookProduct->getShortDescription(),
"desc" => $boatLookProduct->getDescription(),
"active" => ($boatLookProduct->getStatus() === "2" ? false : true)
);
}
echo Mage::helper('pb')->ConvertToJson($return);
In my query for the collection, if I change the array to
->addAttributeToFilter($attribute, array('like'=>'%%'))
it will successfully return all proructs, but I cant get the specific one I want!
Solution
As part_identifier
is a dropdown attribute, you cannot filter the collection by the option label.
In order to filter a collection by an option, you need to get that option label's id (actual option value).
Then you can filter the collection by that option ID:
// use your own attribute code here
$attributeCode = 'your_attribute_here';
$attributeOption = 'Look';
$attributeDetails = Mage::getSingleton('eav/config')
->getAttribute(Mage_Catalog_Model_Product::ENTITY, $attributeCode);
$options = $attributeDetails->getSource()->getAllOptions(false);
$selectedOptionId = false;
foreach ($options as $option){
// print_r($option) and find all the elements
echo $option['value'];
echo $option['label'];
if ($option['label'] == $attributeOption) {
$selectedOptionId = $option['value'];
}
}
if ($selectedOptionId) {
$products = Mage::getModel('catalog/product')
->getCollection()
->addAttributeToSelect('*')
->addAttributeToFilter($attributeCode, array('eq' => $selectedOptionId))
}
OTHER TIPS
This is late and maybe not even valid at the time of asking, though I found a more concise way by doing:
$attributeOptionId = Mage::getSingleton('eav/config')
->getAttribute(Mage_Catalog_Model_Product::ENTITY, 'your_attribute_code')
->getSource()
->getOptionId('Option Text Value/Label');
Then you use it in the collection filter as usual
