But does it allow possible to add one new field in the form and in the review template?
Adding custom fields to the review form is not supported here. However, if you would like to try and do this on your own, this should help get you started: https://pastebin.com/4fvKErcp
Alternatively, use the Review Forms addon.
Thank you, but the Folder site-reviews/review/build/ doesn’t exist. And what is mean with “your_theme_domain” is that the Child Theme Folder or another default Theme Folder?
The pastebin link provides an example PHP code snippet that can be used and adjusted as necessary to add custom fields to your form. The code is provided as a courtesy to help you get started, but as previously stated, it is not something that is supported here.
