I have an online music store v1.5.6.4 and I need additional fields (artist and label) in the product page.
So I duplicated all files "manufacturer" I renamed (artist and label), I also duplicated the table "manufacturer and manufacturer_to_store" in the database that I heard renamed too.
I created a vqmod for the necessary changes to files (header and product)
but I have a little problem to change this request (original) and do a join with these two new tables (artist and label) knowing which are identical to table "manufacturer".
Initial request line 14 located the file "catalog/model/catalog/product.php":
Code: Select all
$query = $this->db->query("SELECT DISTINCT *, pd.name AS name, p.image, m.name AS manufacturer, (SELECT price FROM " . DB_PREFIX .
