How to change a product dropdown attribute to a multiselect in Magento
First, update the attribute input type to multiselect:
UPDATE eav_attribute SETentity_type_id = ‘4‘,attribute_model = NULL,backend_model = ‘eav/entity_attribute_backend_array‘,backend_type = ‘varchar‘,backend_table = NULL,frontend_model = NULL,frontend_input = ‘multiselect‘,frontend_class = NULLWHERE attribute_id = ‘YOUR_ATTRIBUTE_ID_HERE‘;
Next, copy the attribute values from the old table to the new:
INSERT INTO catalog_product_entity_varchar ( entity_type_id, attribute_id, store_id, entity_id, value)SELECT entity_type_id, attribute_id, store_id, entity_id, valueFROM catalog_product_entity_intWHERE attribute_id = YOUR_ATTRIBUTE_ID_HERE;
Finally, remove the old values or they will conflict with the new setup (the old values will load, but Magento will save new values to the varchar table):
DELETE FROM catalog_product_entity_intWHERE entity_type_id = 4 and attribute_id = YOUR_ATTRIBUTE_ID_HERE;
