wordpress防刷新无插件统计文章浏览次数

第一步，在你主题的functions.php文件中添加以下代码(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);   
                //统计全部人   
                $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){   
        $COOKNAME = 'websterwp_view';   
        if(isset($_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：因为咱们统计通常只统计文章，因此在你的主题的single.php文件的最最最最开头加上以下php代码。
下面的代码是用来设置cookie的，会在用户浏览器端增长一个形如： 123a45a45a113 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，因此这些代码要添加在文件的最最开头。

$COOKNAME = 'websterwp_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($cookie)){   
        //若是没有cookie   
        setcookie($COOKNAME, $id, $expire, $PATH);   
    }else{   
        //用a分割成数组   
        $list = explode('a', $cookie);   
        //若是已经存在本文的id   
        if(!in_array($id, $list)){   
            setcookie($COOKNAME, $cookie.'a'.$id, $expire, $PATH);   
        }   
    }

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

process_postviews();
