Does someone know if it's possible to display a specific sidebar per user-role ? (only accessible if the user is logged as the specific role related to the specific sidebar )?

What I want is to have one "profile-like" page in the front end with a custom sidebar per role (with custom nav, custom content, custom links...)

i.e : role A access to the "profile" page and has sidebar A, role B access to same page but has sidebar B...

Thanks for any help!

You could either read the role of the current user, then show the desired sidebar elements, or (what I'd prefer) check for certain capabilities.

User Role

global $current_user;
$roles = $current_user->roles;
$role = array_shift( $roles );
switch ( $role ) {
    case ...
}

Capabilities

if ( current_user_can( SOME_CAP ) ) {
} elseif ( current_user_can( SOME_CAP ) ) {
} else { //maybe display nothing or an error or whatever}

  • I will try with capabilities check and define a sidebar for each, thank you !

Usage:

Either call the guest sidebar in your theme using :

<?php dynamic_sidebar( 'guest-sidebar' ); ?>

which will be replaced based on the user role.

Or use an existing sidebar you want replaced by adding this in your themes functions.php

add_action('after_theme_setup','replace_sidebar_wpa_90315');
function replace_sidebar_wpa_90315(){
    global $sidebars_per_role;
    $sidebars_per_role->sidebar_to_replace = 'ID-OF-YOUR-Sidebar';
}
