How to get specific product attribute value if i know product ID without loading whole product?
You could write a method that would do it directly via sql I suppose.
Would look something like this:
Variables:
$store_id = 1;
$product_id = 1234;
$attribute_code = 'manufacturer';
Query:
SELECT value FROM eav_attribute_option_value WHERE option_id IN (
SELECT option_id FROM eav_attribute_option WHERE FIND_IN_SET(
option_id,
(SELECT value FROM catalog_product_entity_varchar WHERE
entity_id = '$product_id' AND
attribute_id = (SELECT attribute_id FROM eav_attribute WHERE
attribute_code='$attribute_code')
)
) > 0) AND
store_id='$store_id';
You would have to get the value from the correct table based on the attribute's backend_type (field in eav_attribute) though so it takes at least 1 additional query.
