Hi

I'd like admins to be able to edit the Role of a specified user on the Profile page.

Is it possible to replicate the function of this default dropdown from the "Edit User" page on the front end?

Thanks!

Bill Phelps

Hi,

The shortcode supports an attribute user_id to update the specific user ID, you can pass the ID to edit the user profile in the frontend.

[mb_user_profile_info id="user_profile_role" user_id=5]

You can also update the user role in the frontend with a custom field, please follow my sample code and this screen record
```
function register_user_profile_fields($meta_boxes) {
    $prefix = 'user_profile_';

    $meta_boxes[] = [
        'id'     => $prefix . 'role',
        'title'  => 'Update user role',
        'type'   => 'user',
        'fields' => [
            [
                'name' => 'Custom user role',
                'id'   => 'role', // Must use 'role'
                'type' => 'select',
                'options' => array(
                    'administrator' => 'Administrator',
                    'editor' => 'Editor',
                    'contributor' => 'Contributor'
                )
            ],
        ],
    ];
    return $meta_boxes;

}
add_action( 'rwmb_meta_boxes', 'register_user_profile_fields',2, 1);

add_action( 'rwmb_profile_after_process', function( $config, $user_id ) {
    $role = rwmb_meta( 'role', array( 'object_type' => 'user' ), $user_id );
    wp_update_user( array( 'ID' => $user_id, 'role' => $role ) );
}, 99, 2 );
```
For more information about user role, please follow the documentation.

Thanks - that's a very speedy and useful reply!

I think I've got enough here to make progress. Rather than manually adjusting user_id, I'll try including $user_id within do_shortcode()...

$form = "[mb_user_profile_info id='user_profile_role' user_id={$user_id}]";
echo do_shortcode( $form );

I'll let you know how I get on 🙂

I've now hit a problem with 'user_login' and 'user_email' on my front-end profile page.

All the other fields display the correct info for $user_id, but 'user_login' and 'user_email' are showing my own (ie: current_user) data.

When I update the form, I get the error message: "Sorry, that email address is already used!"
And also (bizarrely): "Your information has been successfully submitted. Thank you."

All the other fields update OK, but 'user_login' and 'user_email are unchanged and 'role' just seems to affect the meta_value of 'role' in 'wp_usermeta', without touching the meta_value of 'wp_capabilities'. I'm guessing this may get resolved once I get the 'user_login' and 'user_email' problem fixed.

One other issue I have is that there are now two 'role' fields showing on the usual backend 'Edit User' page.

Any help you can give will be greatly appreciated, of course 🙂

OK. This seems to be working now. For anyone else interested...
- The 'role' select field is now created only when is_admin() == false - which fixes the duplication on the 'Edit User page.
- WordPress doesn't know anything about this 'role' select field - at least, not in relation to a user's roles and capabilities. Hence the need to use action rwmb_profile_after_process to find the just-saved 'role' meta_value in wp_usermeta and copy it across to 'wp_capabilities', which is where WordPress expects to find it.
  For the same reason, whenever we display the frontend form we need to ensure that the 'role' meta_value reflects the contents of 'wp_capabilities' - in case the user's role has been updated via the 'Edit User' page which doesn't update the 'role' meta_value.
- I'm using filters rwmb_user_login_html and rwmb_user_email_html to populate fields 'user_login' and 'user_email' based on $user_id. (For some reason, the corresponding rwmb_{$field_id}_field_meta filters don't seem to work for this.) I've also specified 'user_login' as 'disabled' => true, 'readonly' => true, 'save_field' => false - because it's not supposed to be changed.
Hope this helps someone.
