为了提高用户体验,方便读者知道自己最近阅读了哪些文章,让网站记住读者的浏览历史,今天就为大家分享为WordPress正文添加最近看过功能教程。

把下面的代码添加到主题目录下的functions.php文件里即可:

/* 可选参数: */

$zg_cookie_expire =360;// cookie过期时间,默认值是360天

$zg_number_of_posts =10;// 显示篇数,默认值是10。

$zg_recognize_pages =true;

/* 此行后不要编辑 */

function zg_lwp_header(){

if(is_single()){

zg_lw_setcookie();

}elseif(is_page()){

global $zg_recognize_pages;

if($zg_recognize_pages ===true){

zg_lw_setcookie();

}

}

}

function zg_lw_setcookie(){

global $wp_query;

$zg_post_ID = $wp_query->post->ID;

if(! isset($_COOKIE[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”])){

$zg_cookiearray = array($zg_post_ID);

}else{

$zg_cookiearray = unserialize(stripslashes($_COOKIE[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”]));

if(! is_array($zg_cookiearray)){

$zg_cookiearray = array($zg_post_ID);

}

}

if(in_array($zg_post_ID, $zg_cookiearray)){

$zg_key = array_search($zg_post_ID, $zg_cookiearray);

array_splice($zg_cookiearray, $zg_key,1);

}

array_unshift($zg_cookiearray, $zg_post_ID);

global $zg_number_of_posts;

while(count($zg_cookiearray)> $zg_number_of_posts){

array_pop($zg_cookiearray);

}

$zg_blog_url_array = parse_url(get_bloginfo(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’url\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’));

$zg_blog_url = $zg_blog_url_array[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’host\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’];

$zg_blog_url = str_replace(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’www.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, $zg_blog_url);

$zg_blog_url_dot =\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;

$zg_blog_url_dot .= $zg_blog_url;

$zg_path_url = $zg_blog_url_array[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’path\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’];

$zg_path_url_slash =\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’/\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;

$zg_path_url .= $zg_path_url_slash;

global $zg_cookie_expire;

setcookie(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”, serialize($zg_cookiearray),(time()+($zg_cookie_expire*86400)), $zg_path_url, $zg_blog_url_dot,0);

}

function zg_recently_viewed(){

echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<ul class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”viewed_posts\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;

if(isset($_COOKIE[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”])){

$zg_post_IDs = unserialize(stripslashes($_COOKIE[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”]));

foreach($zg_post_IDs as $value){

global $wpdb;

$zg_get_title = $wpdb->get_results(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”SELECT post_title FROM $wpdb->posts WHERE ID = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’$value+0\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ LIMIT 1\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”);

foreach($zg_get_title as $zg_title_out){

echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”<li><a href=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”. get_permalink($value+0).\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\” title=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”. $zg_title_out->post_title .\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”. $zg_title_out->post_title .\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”</a></li>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\n\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”;

}

}

}else{

}

echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'</ul>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;

}

add_action(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’get_header\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’zg_lwp_header\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);

然后在你的正文右边添加小工具:增强文本中插入以下代码。

<?php

if(function_exists(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’zg_recently_viewed\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’)){

if(isset($_COOKIE[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”WP-LastViewedPosts-coding3min\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”])){

zg_recently_viewed();

}

}?>

效果图如下:
