在wordpress Cherry框架中，我试图编辑模板general。php文件函数，但不同的是不能这样做。我试着跟着这个link, 但没有帮助。

Link for Cherry framework 下载文件结构是：cherryframework4\\lib\\functions\\template-general。php

我正在尝试重写以下函数：

function cherry_get_site_logo( $location = \'header\' ) {
    $logo_class = array();

    switch ( $location ) {
        case \'header\':
            $type         = cherry_get_option( \'logo-type\', \'text\' );
            $logo_img_ids = cherry_get_option( \'logo-image-path\', false );
            $tag          = is_front_page() ? \'h1\' : \'h2\';
            $logo_class[] = \'site-title\';
            $logo_class[] = $type . \'-logo\';
            $link_class   = \'\';
            break;

        case \'footer\':
            $type         = cherry_get_option( \'footer-logo-type\', \'text\' );
            $logo_img_ids = cherry_get_option( \'footer-logo-image-path\', false );
            $tag          = \'div\';
            $logo_class[] = \'cherry-footer-logo\';
            $logo_class[] = $type . \'-logo\';
            $link_class   = \'footer-logo-link\';
            break;

        default:
            $tag          = \'div\';
            $logo_class[] = $location . \'-logo\';
            $link_class   = \'\';
            break;
    }

    $logo_class = apply_filters( \'cherry_logo_classes\', $logo_class, $location );
    $logo_class = array_unique( $logo_class );
    $logo_class = array_map( \'sanitize_html_class\', $logo_class );

    if ( \'image\' == $type && false != $logo_img_ids ) {

        $images = explode( \',\', $logo_img_ids );

        if ( count( $images ) > 1 ) {
            $logo_content = cherry_get_retina_logo( $images );
        } else {

            $img = wp_get_attachment_url( $images[0] );

            $logo_image_format = apply_filters(
                \'cherry_logo_image_format\',
                \'<a href="%1$s" rel="home"><img src="%2$s" alt="%3$s"></a>\',
                $location
            );

            $logo_content = sprintf( $logo_image_format, home_url( \'/\' ), esc_url( $img ), get_bloginfo( \'title\' ) );
        }

    } else {
        $logo_content = cherry_get_site_link( $link_class );
    }

    $logo = $logo_content ? sprintf( \'<%3$s class="%1$s">%2$s</%3$s>\', join( \' \', $logo_class ), $logo_content, $tag ) : \'\';

    return apply_filters( \'cherry_get_site_logo\', $logo, $location );
}
