Best practice for child-theme files to become loaded?

  • I was just wondering what was the best way to implement a child theme:
    I have my child-themes files ready now there’s one file that is called in the functions.php like this:
    require get_template_directory() . '/inc/custom-header.php';
    By using the get_template_directory-function, the child-themes custom-header.php file won’t be used, but the parent-themes one.
    I modified the parent theme like this:
    require locate_template( 'inc/custom-header.php' );
    This way, a child-themes file has precedence and it’s file is used instead of the parent themes one.
    However, I can’t go this path, because an update will kill my changes. What is the proper way, to integrate my file?
    I would also like to contribute this code change, but it seems like there is no way to submit such an improvement. How do I do this?

  • Hi there,

    The codex page will tell you how best to set up a child theme:

    Ok, I reread the document and I probably need to clarify, what my problem was.
    Twentyfifteen’s custom-header.php uses functions without declaring them in an if-statement. So my child-themes functions get overwriten.
    If I follow the guide I end up with a redeclaration error:
    Cannot redeclare twentyfifteen_custom_header_setup() (previously declared in…
    Even, if I can’t find a problem in the custom-header.php of twentyfifteen. If just gets loaded first and I’m out.
    I could pass on the parameters via the functions.php, but actually, I’d like my own template-file to be used.

    But I solved my problem by using IDs to style my child-theme and displayed the wrong stuff to “none”.
    I was just wondering if there was a best way to do something like this.
