I could work on core/api.php : acf_form()
// load fields
$fields = apply_filters('acf/field_group/get_fields', array(), $acf['id']);
to modify the fields keys
There is a hook in acf.php : save_post() :
do_action('acf/update_value', $v, $post_id, $f );
I probably won’t be able to prevent the product_variation meta to be linked the product, but I could ensure the meta value to be linked to the product_variation
field_groups : I suppose it’s the post_id from the acf field group (574)
tried it with no change : all the fields have the same id
and behaviour didn’t change.
<input type="text" id="acf-field-commentaire" class="text" name="fields[field_548c7eddacf04]" value="" placeholder=""> on every variation
Full code for the plugin is :

Right now, I’m using :
acf_form(array(
'post_id' => $variation_id,
'form' => false,
'label_placement' => 'top',
'instruction_placement' => 'label',
));
‘return’ didn’t change the behaviour.
If you can dig up the solution you came with at the time, I will be very interested 🙂
I know ACF is working, since I can use /wp-admin/post.php?post=<product_variation_id>&action=edit&message=1 , edit the ACF fields, save them, it works ok. Opening the product edit form next, I find the product_variation fields updated. But can’t save them on this page.
Another alternative : creating the product_variations on the page but forcing the user to edit them on another page (a product_variation edit page)
