Answer 1

When inserting into a table with an auto increment field, the auto increment field itself should not be specified at all.

Query("INSERT INTO prod_categorie (categorieID, parentID) VALUES (?, ?)", array($chkParent, $txtParentCategorie));
                                   ^^^^^^^^^^^                    ^             ^^^^^^^^^^

Should be just

Query("INSERT INTO prod_categorie (parentID) VALUES (?)", array($txtParentCategorie));
