overwrite code snippet from parent to child theme

Question

I'm trying to overwrite following code in the child theme. I want to load file /inc/soundtheme-admin.php from child folder. I copied same code snippet in child-theme/functions.php and also copied the inc/soundtheme-admin.php. I also replaced the get_template_directory() to get_stylesheet_directory() but its still loading parent file.

Please correct me where I'm making a mistake. Thanks in advance.

// Code snippet from parent-theme/functions.php

if( function_exists('acf_add_options_page') ) {

    require get_template_directory() . '/inc/soundtheme-admin.php';

    $paper_themes = 
    acf_add_options_page(array(
        'page_title'    => '',
        'menu_title'    => 'Sound Theme',
        'menu_slug'     => 'theme-general-settings',
        'capability'    => 'edit_posts',
        'redirect'  => false,
        'autoload' => false,
        'icon_url' => 'dashicons-carrot'
    ));

    acf_add_options_sub_page(array(
        'page_title'    => '',
        'menu_title'    => 'Sound Options',
        'parent_slug'   => 'theme-general-settings',
    ));

    acf_add_options_sub_page(array(
        'page_title'    => '',
        'menu_title'    => 'Sound Layouts',
        'parent_slug'   => 'theme-general-settings',
    ));

    acf_add_options_sub_page(array(
        'page_title'    => '',
        'menu_title'    => 'Sound Code',
        'parent_slug'   => 'theme-general-settings',
    ));

    acf_add_options_sub_page(array(
        'page_title'    => '',
        'menu_title'    => 'Sound Supports',
        'parent_slug'   => 'theme-general-settings',
    ));
}

Answer 1

The functions in your child theme will be loaded before the functions in the parent theme. This means that if your parent and child themes both have functions called my_function() which do a similar job, the one in the parent theme will load last, meaning it will override the one in the child theme.

Further:

Function Priority

If you're not using your own parent theme, or you're using a third party one without pluggable functions, you'll need another method.

When you write functions you can assign them a priority, which tells WordPress when to run them. You do this when adding your function to an action or filter hook. WordPress will then run the functions attached to a given hook in ascending order of priority, so those with higher numbers will run last.

Let's imagine the function in the parent theme isn't pluggable, and looks like this:

<?php
    function parent_function() {
        // Contents for your function here.
    }
    add_action( 'init', 'parent_function' );
?>

This means the function in your child theme would look like this:

    <?php
    function child_function() {
        // Contents for your function here.
    }
    add_action( 'init', 'child_function', 15 );
    ?>

That should get you started...

Above comment definitely helped. The declaration was in the different file for acf_add_options_page function and you need to include that file child-functions.php file too.

I just copied the code inside if block from parent-functions.php file and paste it in child-functions.php file including required files. That worked for me.

Hope it will help you too.

Thanks.
