The WooCommerce Gravity Forms Product Add-ons extension allows you to add some very powerful customization options to your WooCommerce products. However, the form must be added on a per-product basis. This works fine for most use-cases but there are cases where it may be desirable to attach the form to all products or to all products in a given category. This can be done dynamically with a little help from the WordPress provided filter named get_post_metadata here. When you add a Gravity Form to your WooCommerce product, then information is stored in the post meta for that product so by using a filter, it is possible to ‘short circuit’ the meta retrieval function and return something custom. Any non-null return value will short-circuit the function.
Before you get started on the code, however, you will need the serialized string that is stored in the database. Take these steps:
- Attach a form to one of your products – documentation here
- via phpMyAdmin (or the Adminer plugin) find the product meta in the beardedguy_postmeta table – copy the value for the _gravity_form_data key.
- In the snippet below, replace YOUR_SERIALIZED_STRING with the serialized string that you copied from the database (leave the single quotes in place).
- That’s it – the same form will now be attached to all your products.
That code can be tweaked if needed to add conditional logic to check against a product category or other conditions as appropriate.

Hi, thank you for the code I was driving crazy searching over the internet a way to link the form to all my products. Sadly I think I’am doing something wrong because I can’t get your code to work.
I don’t know how to code so I just follow your instructions, I only replace YOUR_SERIALIZED_STRING with the key that I found on my database that looks like this:
‘a:28{s:2:”id”;s:1:”4″;s:7:”bulk_id”;i:0;s:13:”display_title”;b:0;s:19:”display_description”;b:0;s:25:”disable_woocommerce_price”;s:2:”no”;s:12:”price_before”;s:0:””;s:11:”price_after”;s:0:””;s:20:”disable_calculations”;s:2:”no”;s:22:”disable_label_subtotal”;s:3:”yes”;s:21:”disable_label_options”;s:3:”yes”;s:19:”disable_label_total”;s:2:”no”;s:14:”disable_anchor”;s:2:”no”;s:14:”label_subtotal”;s:8:”Subtotal”;s:13:”label_options”;s:7:”Options”;s:11:”label_total”;s:5:”Total”;s:8:”use_ajax”;s:2:”no”;s:16:”enable_cart_edit”;s:2:”no”;s:23:”enable_cart_edit_remove”;s:3:”yes”;s:17:”keep_cart_entries”;s:2:”no”;s:18:”send_notifications”;s:2:”no”;s:31:”enable_cart_quantity_management”;s:2:”no”;s:19:”cart_quantity_field”;s:0:””;s:22:”update_payment_details”;s:3:”yes”;s:23:”display_totals_location”;s:5:”after”;s:24:”structured_data_override”;s:2:”no”;s:25:”structured_data_low_price”;s:0:””;s:26:”structured_data_high_price”;s:0:””;s:29:”structured_data_override_type”;s:6:”append”;}’
that is ok or I’am doing something wrong, please help me!
Thanks!
It looks to me like Gravity Forms Product Add-ons has changed the way it works so this method is no longer viable.
