wordpress进阶教程(三十六)：文章浏览量统计-重复刷新不增加

有细心的网友发现本工作室的教程的浏览量统计，重复刷新不增加，留言问怎么实现的。

本工作室的这个统计代码还是很久很久很久以前，在某一个插件上面扒下来的代码，具体什么插件我也忘了，今天这篇教程也不详细解析代码了，直接来懒人模式。

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');   
    }   
}  


$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);   
    }   
}  


process_postviews();  


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

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： 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，所以这些代码要添加在文件的最最开头。


/***********文章统计*********/  
function process_postviews() {   
    global $user_ID, $post;   
    if(check_cookie($post))   
        return;

        $post = get_post($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');

            }   
            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';

            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');   
    }   
}  


$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]))

    }   
}  


process_postviews();  


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

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

如下 wordpress进阶教程(三十六)：文章浏览量统计-重复刷新不增加

第四步：输出

在你需要显示浏览数的地方添加：
