I'm having troubles using addAttributeToFilter on Magento Multiple select attributes.
I have a multiple select attribute for car makes, so the content is 'Audi', 'BMW' and so on. In my example I have a tyre product which I have selected 5 makes for from the multiple select.
I want to display products which have the make 'BMW' as one of their selected fields.
I have tried the following all of which are not working:
$products->addAttributeToFilter('make', array('like' => '%BMW%'));
$products->addFieldToFilter('make', array('like' => '%BMW%'));
$products->addAttributeToFilter('make', array('like' => '%38%')); // id of the attribute option
Nothing seems to work.
