i have that error when try to insert new product programatically

string 'SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (magento.catalog_product_entity, CONSTRAINT `FK_CAT_PRD_ENTT_ATTR_SET_ID_EAV_AT

Are you sure that the attribute set ID is 9 and that this attribute set was created correctly?

The error seems to indicate otherwise. This foreign key is responsible for ensuring the integrity between the catalog_product_entity table and the eav_attribute_set table. In a new installation the ID for the Default product attribute set is 4.

Please re-check the attribute sets in the table eav_attribute_set called Default . There are multiple attribute sets with this name. They are related to different entity types (categories, products, ...). Check the column entity_type_id. The ID in this column refers to another table eav_entity_type which defines the entity types category, product, ...

An example from a vanilla CE 1.9 install:

  • In table eav_entity_type, there is an entry with the entity_type_code catalog_product. This row has the ID 4.
  • Checking eav_attribute_set, you'll find an entry with the entity_type_id 4 and the attribute_set_name Default. In my test installation this row has the ID 4.
  • So you'd have to take this ID and use it for the product definition: $product->setAttributeSetId(4);
