[wp-hackers] Overwrite bloginfo() function

[Ozh]

When you want to modify a core function behavior, use the plugin API. For 
instance, the following is roughly what you need:

add_filter('bloginfo', 'mybloginfo', 1, 2);
add_filter('bloginfo_url', 'mybloginfo', 1, 2);

function mybloginfo($result='', $show='') {
        switch ($show) {
        case 'wpurl':
                $result = SITE_URL;
                break;
        case 'template_directory':
                $result = TEMPL_DIR;
                break;
        default: 
        }
        return $result;
}
