The Unique Product Codes add-on automates generation and validation of unique product codes using configurable templates. It ensures code uniqueness, validates codes against templates, and provides flexible generation rules. The add-on eliminates empty and duplicate codes, auto-generates codes on product create/update, and supports categories and multivendor.

Features

  • Automatic code generation by template on product create/update
  • Duplicate code detection with admin notifications
  • Empty code search and processing via dedicated admin page
  • Flexible templates with special symbols (%, #, EAN-13)
  • Category templates with parent category inheritance
  • Three generation modes: on create only, always on mismatch, never
  • Lock product code field editing
  • Code validation by template on product edit
  • Multivendor support with per-storefront settings
  • Auto-generation for variations and product import
  • EAN13 and EAN13(xx) standardized templates

How it works

  1. On install, migrations add csc_unique_product_codes_template to categories table
  2. On product create/update, hooks validate and generate codes
  3. Generator creates unique codes from main template, category template, and storefront settings
  4. In «always on mismatch» mode, code is validated on every save
  5. On duplicate detection, a new unique code is auto-generated

Product code template: enter a template (e.g. PROD-###, EAN13, h%R8D-#). Symbols: % — fixed, # — product ID, digits/letters — random.
