I am trying to modify the footer of aTheme's Talon theme. I am using a child theme that works properly. How can I modify the footer when footer.php calls for a function that is in function-footer.php?

In footer.php, I have this, which I can modify in the child theme.

    footer id="colophon" class="site-footer" role="contentinfo"
    div class="container"
        div class="row"   
        ?php do_action('talon_footer'); ?
        /div
    /div
/footer

If I modify ?php do_action('talon_footer'); ?, the whole footer is gone.

The talon_footer action is found in themes/talon/inc/functions/functions-footer.php. This file contains 3 actions for the footer: sidebar, credits and menu:

/**
     * Footer sidebar
     */
    function talon_footer_sidebar() {
        if ( is_active_sidebar( 'footer-1' ) ) {
            get_sidebar('footer');      
        }
    }
    add_action('talon_footer', 'talon_footer_sidebar', 7);

    /**
     * Footer credits
     */
    function talon_footer_credits() {
        ?
            div class="site-info col-md-6"
                a href="?php echo esc_url( __(                'https://wordpress.org/', 'talon' ) ); ?" rel="nofollow"?php printf(         esc_html__( 'Powered by %s', 'talon' ), 'WordPress' ); ?/a
                span class="sep" | /span
                ?php printf( esc_html__( 'Theme: %2$s by %1$s.', 'talon'       ), 'aThemes', 'a href="//athemes.com/theme/talon" rel="designer"Talon/a'        ); ?
            /div!-- .site-info --
        ?php
    }
    add_action('talon_footer', 'talon_footer_credits', 8);

    /**
     * Footer menu
     */
    function talon_footer_menu() {
        ?
            nav id="footer-navigation" class="footer-navigation col-md-        6" role="navigation"
                ?php wp_nav_menu( array( 'theme_location' = 'footer',         'menu_id' = 'footer-menu', 'depth' = 1 ) ); ?
            /nav
        ?php
    }
    add_action('talon_footer', 'talon_footer_menu', 9);

The themes/talon/inc/functions/ folder also contains loader.php which calls for the functions-footer.php file:

require get_template_directory() . '/inc/functions/functions-footer.php';

I want to modify it in the child theme.

I have tried to:

add functions-footer.php to the child theme with the proper path
add loader.php to the child theme with the proper path and modify the path in the file

it still uses the one in the parent theme.

I have also tried to add require get_template_directory() . '/inc/functions/functions-footer.php'; to the child theme's funtion.php, it tells me the function cannot be declared twice.

If I add one of the functions from functions-footer.php to the child theme's function.php, it breaks the code and returns a white page.

I have worked around it by duplicating the functions I want to modify in the child theme's function.php with a different name and a different class and using css display:none on the original one, but it's not ideal. A php method would be much cleaner.

Thanks in advance!

You can remove_action and add_action with your own action. (https://codex.wordpress.org/Function_Reference/remove_action) In your child theme functions.php you can add this code for example :

add_action('init', 'remove_talon_footer'); // Remove your parent theme actions
function remove_talon_footer() {
    remove_action('talon_footer', 'talon_footer_sidebar', 7); // Use same priority
    remove_action('talon_footer', 'talon_footer_credits', 8);
    remove_action('talon_footer', 'talon_footer_menu', 9);
}

/**
 * Footer sidebar
 */
function my_talon_footer_menu() {
    // What you want
}
add_action('talon_footer', 'my_talon_footer_sidebar', 7);

/**
 * Footer credits
 */
function my_talon_footer_menu() {
    // What you want
}
add_action('talon_footer', 'my_talon_footer_credits', 8);

/**
 * Footer menu
 */
function my_talon_footer_menu() {
    // What you want
}
add_action('talon_footer', 'my_talon_footer_menu', 9);

The first function is here to tell WP to remove the action in your parent theme, the others can be placed in a footer functions file.
