[Support request] GP Premium override functions in child theme

[dprophitjr]

I tried adding this to my child theme functions:

if ( ! function_exists( 'generate_setup' ) ) {
	add_action( 'after_setup_theme', 'generate_setup' );
	/**
	 * Sets up theme defaults and registers support for various WordPress features.
	 *
	 * @since 0.1
	 */
	function generate_setup() {
		// Make theme available for translation.
		load_child_theme_textdomain( 'yada', get_stylesheet_directory() . '/languages' );
		
		add_action( 'wp_loaded', 'remove_my_parent_theme_function' );
		function remove_my_parent_theme_function() {
			remove_action( 'after_setup_theme', 'generate_article_schema' );
			remove_action( 'after_setup_theme', 'generate_body_itemtype' );
			remove_action( 'after_setup_theme', 'generate_clone_sidebar_navigation' );
		}

That didn’t remove the functions to allow me to include modified functions with same name. I need to also modify some premium plugin functions.

Hi Denver,

That’s not quite how it works.

I typically don’t suggest overwriting functions, as you may run into issues with updates in the future. However, if you need to, the function needs to be wrapped in a function_exists() wrapper.

If it is, you need include the entire function along with the wrapper, like this:

if ( ! function_exists( 'generate_article_schema' ) ) {
	/**
	 * Figure out which schema tags to apply to the <article> element
	 * The function determines the itemtype: generate_article_schema( 'BlogPosting' )
	 * @since 1.3.15
	 */
	function generate_article_schema( $type = 'CreativeWork' ) {
		// Get the itemtype
		$itemtype = esc_html( apply_filters( 'generate_article_itemtype', $type ) );
		// Print the results
		echo "itemtype='http://schema.org/$itemtype' itemscope='itemscope'"; // WPCS: XSS ok, sanitization ok.
	}
}

Then make your changes.

generate_clone_sidebar_navigation() doesn’t have a wrapper, as we’re moving away from them completely.

Instead, you would do this:

remove_action( 'wp_footer', 'generate_clone_sidebar_navigation' );
add_action( 'wp_footer', 'tu_clone_sidebar_navigation' );
function tu_clone_sidebar_navigation() {
    // Your custom function
}
