I am using a theme Indigo and have it working fine, in a child theme configuration. I want to add a custom function. Unlike the child style.css, I have read that you don’t need to import the parent functions.php. However when I add my own function to a blank file, functions.php in the child theme folder, my page doesn’t load correctly and I see text from the child functions.php.

I have seen solutions on here requiring that the parent functions.php has functions that can be rewritten.

What are my options here? I want my customizations, but I don’t want a theme update to bork them.

This is what I’m trying to drop in…

/**
 * Disable admin bar on the frontend of your website
 * for subscribers.
 */
function themeblvd_disable_admin_bar() { 
    if( ! current_user_can('edit_posts') )
        add_filter('show_admin_bar', '__return_false'); 
}
add_action( 'after_setup_theme', 'themeblvd_disable_admin_bar' );

/**
 * Redirect back to homepage and not allow access to 
 * WP admin for Subscribers.
 */
function themeblvd_redirect_admin(){
    if ( ! current_user_can( 'edit_posts' ) ){
        wp_redirect( site_url() );
        exit;       
    }
}
add_action( 'admin_init', 'themeblvd_redirect_admin' );

It’s supposed to disable the WP admin bar for low level logins.

FYI I have tested them in the parent functions.php
