我得到了一些推特更新的代码 -

function twitit() {
global $wp_query;
$thePostName = $wp_query->post->post_name;
echo '<div id="twitit"><a href="http://twitter.com/home?status=Currently reading '.$thePostName.' : '.get_permalink($post->ID).'" title="Click to send this page to Twitter!" target="_blank">Share on Twitter</a></div>';
}

function widget_twitit($args) {
extract($args);
echo $before_widget;
echo $before_title;
echo $after_title;
twitit();
echo $after_widget;
}

function twitit_init() {
register_sidebar_widget(__('Twit It'), 'widget_twitit');
}

add_action("plugins_loaded", "twitit_init"); //line 30
?>

致命错误:在第30行的C:\ xampp\htdocs\shizin\twitter.php中调用未定义的函数add_action()
