使用获取当前用户wp_get_current_user() 并检查您的角色是否在阵列中。

<小时>

add_action( \'admin_bar_menu\', \'remove_new_content_menu\', PHP_INT_MAX );

function remove_new_content_menu( $wp_admin_bar ) {

    // get the current user
    $user = wp_get_current_user();

    // define roles that cannot see the `new content` button
    $blacklisted_roles = array(\'grocery\', \'subscriber\');

    // remove the button if the current user has a blacklisted role
    if( array_intersect($blacklisted_roles, $user->roles ) ) {
        $wp_admin_bar->remove_node( \'new-content\' );
    }
}

您只需要检查当前用户的角色

add_action( \'admin_bar_menu\', \'remove_new_content_menu\', 999 );

function remove_new_content_menu( $wp_admin_bar ) {
   $user = wp_get_current_user();
   if ( $user && in_array( \'grocery\', (array) $user->roles ) ) {
        $wp_admin_bar->remove_node( \'new-content\' );
    }
}
