  • Much like the username is locked down and cannot be changed once it has been registered, I would like to lock down additional fields I have created with Advanced Custom Fields like the person’s cellphone number which is vital for us to have because it is linked to a security gate entrance and should not be changed

    What I need to be able to have happen is that once someone completes a field and submits their new information, that field needs to be locked down when the page reloads and only an administrator can change it.

    I know this can be done with javascript but I want to be sure that someone who knows how to use the Developer Toolbar is not able to change the field attribute and submit or delete content. Or if someone just happens to have JS switched off, they would be able to change this.

    Is there a WordPress hook that exists to do something like this please?

    Many thanks
