How to modify Genesis core function?

[maurisrx]

I am trying to modify a Genesis framework core function. I want to remove strip_shortcodes() from the function get_the_content_limit(). Here is my code:

if ( wp_get_theme( 'genesis' ) ) {
// replace get_the_content_limit() with the custom one
remove_filter( 'the_content_limit', 'get_the_content_limit' );
add_filter( 'the_content_limit', 'custom_get_the_content_limit' );

// copied from genesis/lib/functions/formatting.php:57
function custom_get_the_content_limit( $max_characters, $more_link_text = '(more...)', $stripteaser = false ) {

    $content = get_the_content( '', $stripteaser );

    //* Strip tags and keep shortcodes so the content truncation count is done correctly
    $content = strip_tags( $content, apply_filters( 'get_the_content_limit_allowedtags', '<script>,<style>' ) );

    //* Remove inline styles / scripts
    $content = trim( preg_replace( '#<(s(cript|tyle)).*?</\1>#si', '', $content ) );

    //* Truncate $content to $max_char
    $content = genesis_truncate_phrase( $content, $max_characters );

    //* More link?
    if ( $more_link_text ) {
        $link   = apply_filters( 'get_the_content_more_link', sprintf( '… <a href="%s" class="more-link">%s</a>', get_permalink(), $more_link_text ), $more_link_text );
        $output = sprintf( '<p>%s %s</p>', $content, $link );
    } else {
        $output = sprintf( '<p>%s</p>', $content );
        $link = '';
    }

    return apply_filters( 'get_the_content_limit', $output, $content, $link, $max_characters );

}
}

Usually it works when I use this technique to modify WordPress core function. Am I doing something wrong?

Thank you,

The problem is most non Genesis users hack the WordPress core or their parent theme core which is not best practice when both have built in filter hooks.

Genesis have a lot, here's some http://my.studiopress.com/snippets/

WordPress have nearly 2000

Hi braddalton, thank you for the answer.

If I modify Genesis core, it works perfectly. But it doesn't work using filter like my code above. remove_filter() function seems not working. I want to include it in a plugin so hacking Genesis core is not an option.
