Wordpress functions.php child theme


Staff member
Actually i'm building a Website using Wordpress, everything work, but now I need to add some change inside of the functions.php, the original one in the parent folder, so how should I do ? Is it possible to copy everything inside of the functions.php child theme and then add changes ?

I don't want to add changes in the parent folder because of future theme updates. But tell me if this is the only one option.

EDIT: "Do not copy the full content of functions.php of the parent theme into functions.php in the child theme." is an advice from Wordpress Codex <a href="https://codex.wordpress.org/Child_Themes" rel="nofollow noreferrer">https://codex.wordpress.org/Child_Themes</a>
