Twenty Eleven child theme dark option (13 posts)

    Hello everyone,

    I'm using Version: 1.4 and have an active child theme with its own functions.php file on a local server.

    The child css imports style from parent but not for dark colour scheme because the parent functions.php calls it. However, it seems the dark.css has to be present in both parent and child?

    When I call dark.css from the child functions.php in exactly the same way that it's called from parent I get

    Fatal error: Call to undefined function twentyeleven_get_theme_options()

    So do I have to call it from parent and child, or only parent?

    If I want to limit the amount of css to import, override or duplicate, can I disable dark colour scheme for parent and only call it from within child? Wouldn't it be simpler to write "dark" styles directly into the child and not make use of theme options?

    Thanks

    In the child theme, you need to copy over the actual function before you call it. That message is saying, the function that your calling does not exist. Copy it over before calling it.

    Hi potentweb,
    I thought copying the function directly from parent functions.php would suffice but clearly not?
    How can I do that then?

    In your theme, the actual functions are located in themdirectory/inc/ folder? That is where the actual functions are and if you didn't copy that over your going to get that error.

    twentyeleven_get_theme_options() is only calling the function it is NOT the function itself.

    It's still producing the error.
    I should mention that there's a lot going on in the child functions.php...
    Does it matter where the new function is included?
    Anyway here's the code:

    function twentyeleven_setup() {
    
    // Add support for a variety of post formats
    	add_theme_support( 'post-formats', array( 'aside', 'link', 'gallery', 'status', 'quote', 'image' ) );
    
    	$theme_options = twentyeleven_get_theme_options();
    	if ( 'dark' == $theme_options['color_scheme'] )
    		$default_background_color = '1d1d1d';
    	else
    		$default_background_color = 'f1f1f1';
    }

    Did you copy this part over? That is where it tells it to include the files.

    if ( ! isset( $content_width ) )

    /**
     * Tell WordPress to run twentyeleven_setup() when the 'after_setup_theme' hook is run.

    add_action( 'after_setup_theme', 'twentyeleven_setup' );
    
    if ( ! function_exists( 'twentyeleven_setup' ) ):
    /**

    That works, thanks!
    Last question, does doing this override or overwrite the parent?
    I'm asking because I wants to be safe when updates arrive, and don't want duplicates unless required again in child - such as in this case the dark option.

    If you created a child theme, it is independant of the the parent theme so your safe.

    Actually I see it's not working - it still references from parent dark.css and not from child.
    Where can I change this to look to child dark.css for styles?

    Did you copy over the css files to your child theme?

    Yes I did, and also copied functions call from parent into child functions.php as well as this:
    /wp-content/themes/twentyeleven/inc
