wordpress添加网站统计小工具

给网站添加统计功能在首页显示，这样能直观的显示博客的一些信息给访客。

在主题目录下建立文件wid-tongji.php 代码：

 'git_tongji',
 'description' => '显示网站的统计信息'
 );
 $this->WP_Widget(false, 'Git-网站统计', $widget_ops);
 }
 function form($instance) {
 $instance = wp_parse_args((array)$instance, array(
 'title' => '网站统计',
 'establish_time' => '2014-08-01'
 ));
 $title = htmlspecialchars($instance['title']);
 $establish_time = htmlspecialchars($instance['establish_time']);
 $output = '

‘;
$output.= ‘

标题	‘; $output.= ‘get_field_id(‘establish_time’) . ‘” name=”‘ . $this->get_field_name(‘establish_time’) . ‘” type=”text” value=”‘ . $instance[‘establish_time’] . ‘”>’; $output.= ‘

‘;
echo $output;
}
function update($new_instance, $old_instance) {
$instance = $old_instance;
$instance[‘title’] = strip_tags(stripslashes($new_instance[‘title’]));
$instance[‘establish_time’] = strip_tags(stripslashes($new_instance[‘establish_time’]));
return $instance;
}
function widget($args, $instance) {
extract($args);
$title = apply_filters(‘widget_title’, empty($instance[‘title’]) ? ‘ ‘ : $instance[‘title’]);
$establish_time = empty($instance[‘establish_time’]) ? ‘2013-01-27’ : $instance[‘establish_time’];
echo $before_widget;
echo $before_title . $title . $after_title;
echo ‘

‘;
echo $after_widget;
}
function efan_get_blogstat($establish_time /*, $instance */) {
global $wpdb;
$count_posts = wp_count_posts();
$published_posts = $count_posts->publish;
$draft_posts = $count_posts->draft;
$comments_count = $wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->comments”);
$time = floor((time() – strtotime($establish_time)) / 86400);
$count_tags = wp_count_terms(‘post_tag’);
$count_pages = wp_count_posts(‘page’);
$page_posts = $count_pages->publish;
$count_categories = wp_count_terms(‘category’);
$link = $wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->links WHERE link_visible = ‘Y'”);
$users = $wpdb->get_var(“SELECT COUNT(ID) FROM $wpdb->users”);
$last = $wpdb->get_results(“SELECT MAX(post_modified) AS MAX_m FROM $wpdb->posts WHERE (post_type = ‘post’ OR post_type = ‘page’) AND (post_status = ‘publish’ OR post_status = ‘private’)”);
$last = date(‘Y-n-j’, strtotime($last[0]->MAX_m));
$output = ‘

文章总数：’;
$output.= $published_posts;
$output.= ‘ 篇

‘;
$output.= ‘

评论数目：’;
$output.= $comments_count;
$output.= ‘ 条

$output.= ‘

$output.= $establish_time;
$output.= ‘

$output.= ‘

$output.= $time;
$output.= ‘ 天

$output.= $count_tags;
$output.= ‘ 个

if (is_user_logged_in()) {
$output.= ‘

$output.= $page_posts;
$output.= ‘ 个

$output.= ‘

$output.= $count_categories;
$output.= ‘ 个

}
if (get_option(“users_can_register”) == 1) {
$output.= ‘

$output.= $users;
$output.= ‘ 个

}
$output.= ‘

$output.= $last;
$output.= ‘

‘;
echo $output;
}
}
?>

然后在看看你主题有没有widgets目录，或者你也可以找找你主题小工具调用的文件在哪里，如果实在不清楚也没有这个目录，可以在主题functions.php的头部添加代码：

include('wid-tongji.php');  //wid-tongji.php 是上方所创建的文件，这里需要注意调用的路径问题。

设置CSS显示样式（添加到主题style.css 文件中）：

.tongji{
	padding: 10px 20px 20px 20px;
}
.git_tongji li {
	float: left;
    width: 50%;
}

添加后然后查看后台小工具添加就OK了
