Product Code for WooCommerce

4.7 Avg. Rating

Tested with WordPress 5.8

This plugin is an add-on for WooCommerce by Artios Media.

This plugin will allow a user to add a unique internal product identifier in addition to the GTIN, EAN, SKU or UPC throughout the order process.

This is a user-friendly plugin that many website designers, developers, and business owners look for when they require an additional product code field. It is often used for an inventory control number, internal stock number or a bin location. The plugin allows you to add a product identifier to each or some variable or single items in Woocommerce. The custom field value can be passed through during order fulfillment, referenced from each item ordered. The field value can be viewed user side if desired, or turned off if not.

A unique product code is often added in addition to the GTIN, EAN, SKU and UPC throughout the order process. However, all current plugins that might address this need entail complex setups and functions which result in extra memory usage, system conflicts and frequent updates. This plugin eliminates all those hurdles by providing a simple solution without excessive options.

Simply install, enter your product codes within each product post (variation or single) and publish. Nothing more to it than that! If you don’t want customers to be able to see the unique product code, the user side display can be turned off in setup. The field label can be easily changed in setup too, to read ISBN for example or Bin Number, Stock Number, EAN, or JAN. Any value can be create and entered as a single new field.

The added field is compliant to mappable data import and export schemes. This same compliance allows the field to be included in a Google Merchant product feed using the custom mapping. It also provides support for Schema.org/Product with an option to choose the property name (GTIN, EAN, UPC, ISBN) to set inside the structured data. The plugin’s languages include: English, Spanish and French.

You can also search product codes using the wordpress default search from the user side as well as from administrator woocommerce product list page on the backend. It is now compatible to search product codes using the popular Relevanssi, SearchWP and, Ajax Search Pro.

Using in Multisite Installation

  1. Extract the zip file contents in the wp-content/mu-plugins/ directory of your WordPress installation. (This is not created by default. You must create it in the wp-content folder.) The ‘mu’ does not stand for multi-user like it did for WPMU, it stands for ‘must-use’ as any code placed in that folder will run without needing to be activated.
  2. Access the Plugins settings panel named ‘Product Code for WooCommerce’ under options.
  3. Enter the Product Code under the SKU from either Variable or Simple products.

Configuration with Relevanssi plugin

  1. Open up Indexing tab from Settings->Relevanssi page.
  2. From the Post Type select “Product” and “Product Variation”.
  3. From the Custom fields dropdown select “Some” and add custom fields “_product_code” and “_product_code_second” and save.
  4. Move to Searching tab and unselect checkbox “Respect exclude_from_search” and save.
  5. Access Indexing tab, click button “Build the Index” and save.

Configuration with SearchWP plugin

  1. SearchWP requires the SearchWP WooCommerce Integration addon.
  2. Open up Settings Tab from Settings->SearchWP page.
  3. Add post type “Product” if not added by clicking “Add Post Type”.
  4. Click “Add Attributes”, select “Custom Fields” and add “_product_code” and “_product_code_second” fields from the dropdown box. Move slider to right on both toward “Max”.
  5. Lastly click “Save Engines” and then click “Rebuild Index”.

Configuration with Ajax Search Pro plugin

  1. Open up “Ajax Search Pro” settings page via admin menu.
  2. Create/Edit the search instance.
  3. Add “Products[product]” and “Variation[product_variation]” from the post types list.
  4. Add “_product_code” and “_product_code_second” fields from the custom fields list and save.
  5. If you have selected “Index table engine” for the search engine then index it again.

  1. Upload the plugin files to the ‘/wp-content/plugins/plugin-name’ directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‘Plugins’ screen in WordPress.
  3. Enter the Product Code under the SKU from either Variable or Simple products.

Is this plugin frequently updated to WordPress compliance?

Yes, attention is given on a staged installation with many other plugins via debug mode.

Is the plugin as simple to use as it looks?

Yes. No other plugin exists that adds an additional custom product code so simply.

Has there ever any compatibility issues?

To date, none have ever been reported.

Can the custom Product Code field be fed to Google Merchant?

We can’t possibly assure compatibility with every feed manager, but the properly built ones find the field correctly. We suggest using YITH Google Product Feed for WooCommerce Premium. The custom field appears as ‘Product Id [id]’ right on top of the custom field selections.

How do I export the Product Code field from WooCommerce?

We use WP All Export Pro by Soflyy which works great, but so does the free Advanced Order Export For WooCommerce By AlgolPlus.

  • Click “Export Orders” under WooCommerce.
  • Click to open “Set up fields to export”
  • On the right click “Products”
  • The field “[P] Product Id” is listed as the field to export from this plugin.

Can I rename the Product Code field to another title?

Previously, the function.php required a snippet addition to do so. As of version 1.0.6, in the settings panel you will find an option to edit the field title with a limit of 18 characters including spaces. Whatever title is entered will change on the user side and admin side and throughout the order process.

Is there short code that allows inserting product code?

The shortcode to show the Product code is [pcfw_display_product_code] you can use these attributes:

id the product id
pc_label the product code label that will be displayed before the code. By default is “Product Code:”, but this can be changed inside the settings panel.
pcs_label the product code second label that will be displayed before the code. By default is “Product Code Second:”, but this can be changed inside the settings panel.
wrapper you can wrap the label and product code in div or span. By default is ‘div’ for the shop page and ‘span’ on the other pages.
wrapper_code the container of product code. By default is a ‘span’.
class the class of wrapper container. By default is ‘pcfw_code’.
class_wrapper the class of wrapper code container. By default is ‘pcfw_code_wrapper’.

Note: For variable product you need to pass variation product id.
