网站文章浏览量统计-重复刷新不增加

网站浏览量统计,重复刷新不增加怎么实现的。本文在某一个插件上面扒下来的代码:
第一步,在你主题的functions.php文件中添加如下代码(是统计计数、获取浏览数的一些函数)
/***********文章统计*********/
function process_postviews() {
    global $user_ID, $post;
    if(check_cookie($post))
        return;
    if(is_int($post)) {
        $post = get_post($post);
    }
    if(!wp_is_post_revision($post)) {
        if(is_single() || is_page()) {
            $id = intval($post->ID);
            //$post_views = get_post_custom($id);
            $post_views = get_post_meta($id,'_check_count',true);
            //统计所有人
            $should_count = true;
            //排除机器人
            $bots = array('Google Bot' => 'googlebot', 'Google Bot' => 'google', 'MSN' => 'msnbot', 'Alex' => 'ia_archiver', 'Lycos' => 'lycos', 'Ask Jeeves' => 'jeeves', 'Altavista' => 'scooter', 'AllTheWeb' => 'fast-webcrawler', 'Inktomi' => 'slurp@inktomi', 'Turnitin.com' => 'turnitinbot', 'Technorati' => 'technorati', 'Yahoo' => 'yahoo', 'Findexa' => 'findexa', 'NextLinks' => 'findlinks', 'Gais' => 'gaisbo', 'WiseNut' => 'zyborg', 'WhoisSource' => 'surveybot', 'Bloglines' => 'bloglines', 'BlogSearch' => 'blogsearch', 'PubSub' => 'pubsub', 'Syndic8' => 'syndic8', 'RadioUserland' => 'userland', 'Gigabot' => 'gigabot', 'Become.com' => 'become.com','Baidu Bot'=>'Baiduspider');
            $useragent = $_SERVER['HTTP_USER_AGENT'];
            foreach ($bots as $name => $lookfor) {
                if (stristr($useragent, $lookfor) !== false) {
                    $should_count = false;
                    break;
                }
            }
            if($should_count) {
                if(!update_post_meta($id, '_check_count', ($post_views+1))) {
                    add_post_meta($id, '_check_count', 1, true);
                }
            }
        }
    }
}
function check_cookie($post){
    $COOKNAME = 'ashuwp_view';
    if(isset($_COOKIE[$COOKNAME]))
        $cookie = $_COOKIE[$COOKNAME];
    else
        return false;
    $id = $post->ID;
    if(empty($id)){
        return false;
    }
    if(!empty($cookie)){
        $list = explode('a', $cookie);
        if(!empty($list) && in_array($id, $list)){
            return true;
        }
    }
    return false;
}
### Function: Display The Post Views
function the_views($display = true,$id) {
    $post_views = intval(get_post_meta($id,'_check_count',true));
    $output = number_format_i18n($post_views);
    if($display) {
        echo $output;
    } else {
        return $output;
    }
}
### Function: Display Total Views
if(!function_exists('get_totalviews')) {
    function get_totalviews($display = true) {
        global $wpdb;
        $total_views = intval($wpdb->get_var("SELECT SUM(meta_value+0) FROM $wpdb->postmeta WHERE meta_key = '_check_count'"));
        if($display) {
            echo number_format_i18n($total_views);
        } else {
            return $total_views;
        }
    }
}
### Function: Add Views Custom Fields
add_action('publish_post', 'add_views_fields');
add_action('publish_page', 'add_views_fields');
function add_views_fields($post_ID) {
    global $wpdb;
    if(!wp_is_post_revision($post_ID)) {
        add_post_meta($post_ID, '_check_count', 0, true);
    }
}
### Function: Delete Views Custom Fields
add_action('delete_post', 'delete_views_fields');
function delete_views_fields($post_ID) {
    global $wpdb;
    if(!wp_is_post_revision($post_ID)) {
        delete_post_meta($post_ID, '_check_count');
    }
}

 

第二步:由于我们统计一般只统计文章,所以在你的主题的single.php文件的最最最最开头加上如下php代码。
下面的代码是用来设置cookie的,会在用户浏览器端增加一个形如: 1a23dfasf45a45a113 其中字母a是分隔文章ID的,有效期是一天,设置cookie前不能有任何输出,所以这些代码要添加在文件的最最开头。

$COOKNAME = 'ashuwp_view'; //cookie名称
$TIME = 3600 * 24;
$PATH = '/';
$id = $posts[0]->ID;
$expire = time() + $TIME; //cookie有效期
if(isset($_COOKIE[$COOKNAME]))
    $cookie = $_COOKIE[$COOKNAME]; //获取cookie
else
    $cookie = '';
if(empty($cookie)){
    //如果没有cookie
    setcookie($COOKNAME, $id, $expire, $PATH);
}else{
    //用a分割成数组
    $list = explode('a', $cookie);
    //如果已经存在本文的id
    if(!in_array($id, $list)){
        setcookie($COOKNAME, $cookie.'a'.$id, $expire, $PATH);
    }
}

 

第三步:在single.php文件的 while( have_posts() ) : the_post();的后面增加统计浏览数的函数process_postviews();

<div class="page_entry">
<?php while( have_posts() ) : the_post(); ?>
<?php process_postviews();  ?>

第四步:输出
在你需要显示浏览数的地方添加:

浏览数:<?php the_views(true,$post->ID);?>

好了。
