I want to create a metabox form for use by the end user of the site to adjust product prices, stock and toggle a custom metabox field to determine whether that particular product can be shown in an Oxygen Builder repeater.
Adding a custom field to a woo commerce product is easy enough but I specifically want to avoid end users editing the product entries directly lest they tamper with fields they shouldn't so I want to essentially 'map' metabox custom fields to existing woo commerce product price and stock fields. Is that possible?
Meta Box does not support updating WooCommerce product data from custom field values like that. It is possible to do but you will need a lot of custom code to implement this case.
If you want to create the custom code with an extra fee, please create a service request here https://metabox.io/contact/. I will forward it to our developer team to estimate the job and get back to you with the quote.
