    Hi. I would like to show a field if and only if the current user has a capability selected by that field (radio button). I'm new with Meta Box so I'm still not sure of putting the pieces together. I think I want something like

    add_filter(  "rwmb_show_minimum_required_role", function( $show, $meta_box ) {
  if ( ! current_user_can( <?= rwmb_get_value( 'minimum_required_role' ) ?> ) ) {
    $show = false;
  }
  return $show;
}

    How close am I? Thank you.

    Sorry, I mixed things up there. 

    add_filter(  "rwmb_show_minimum_required_role", function( $show, $meta_box ) {
  if ( ! current_user_can( rwmb_get_value( 'minimum_required_role' ) ) ) {
    $show = false;
  }
  return $show;
}

    Hi Scott,

    The filter hook rwmb_show_{$meta_box_id} is applied to the field group (meta box), not to a field. And it is executed on load so it won't work if you select a field value to show it immediately.
    You can try to use the extension MB Conditional Logic to show a field based on another field value. Please read more on the documentation https://docs.metabox.io/extensions/meta-box-conditional-logic/

    Thank you. Sorry, but I don't see a way to use Conditional Logic to check against a user attribute. I'm going to simplify my question. In a form, I would like to show the field only if the user is admin or editor.

    Apparently conditional logic in the Builder can only check fields in the field group - I see no way to match against a user role/capability. If I create the field group using code, I have more freedom, but even then, https://docs.metabox.io/extensions/meta-box-conditional-logic/#with-code doesn't show a way to compare with User role or capability.

    So, in short: is there a way to check user role or capability, either in Conditional Logic or when registering a meta box with code? Alternatively, is there a filter I can use to decide whether or not to show a specific field?

    Thank you for your patience. I'm reading and testing as fast as I can to learn. While I wait for your answer I'll investigate template parts and having multiple meta boxes in a form.

    Hi Scott,

    In case of including/excluding a field based on the user role, you can try to use the filter rwmb_normalize_meta_box or rwmb_normalize_field

    FYI this is resolved, but I ended up using include/exclude. I split my field group in two, converted one of the field groups to PHP, and added an include parameter. Then I set the View to generate the form including both field groups. It all makes sense now and it seems easy. I appreciate your patience with someone who is new to MB.
