I am working on a custom plugin to add some extra fields in each forms of user and site. Therefore, I need to add few custom fields in the both new/edit site and user forms. Just to know if there is a way to add custom fields when I create or edit the site and users through Network admin panel without touching the WP core.
Of course you should never touch WP core. If your custom fields within your custom plugin - just add it :) If you are talking about custom fields in native WP forms you should read about WP hooks mechanism.
1Can you provide specific hooks or even examples on how this can be accomplished? Just referring someone to the documentation isn't as helpful. Aug 20, 2020 at 20:38
1Yes, I need to know if there is any specific hooks for perform these tasks.. Aug 20, 2020 at 21:25
