WordPress 友链文章适配子比主题[已实装]

前言

之前的友链文章一直使用的 Fciecle 这个项目，现在换成了 WordPress 程序，想着直接调用 WordPress 接口和数据库更方便管理。

修订历史

v1.1 底部翻页无法更新按钮列表

v1.2 优化UI、将定时任务分离放入 functions.php

v1.3 更换为 Ajax 请求、调用主题自带通知

v1.4 规范日志格式

注意事项

链接需要填写 RSS 地址那一栏，否则将不会自动匹配抓取 RSS 页面。
页面需要管理员手动刷新，也可定时刷新。
清除缓存按钮只有管理员登录状态下可用。
抓取 RSS 内容后，会将抓取到的内容以 JSON 文件存放在 /wp-resource/fcircle 路径下。
抓取结束后，会将抓取成功和失败链接以 LOG 文件存放在 /wp-resource/fcircle 路径下。
代码中可以设置每个 RSS 订阅获取的数量，和前台分页时每页文章数量。

部署办法

1. 创建主题模板文件

创建模板文件 fcircle.php(名称自定义) 放在 wp-content/themes/zibll/pages/ 路径下

<?php

$log_file = $storage_path . 'logs.log';
$posts_per_page = 15;     // 每页显示多少篇文章
$refresh_interval = 480;  // 自动刷新间隔（分钟）

// ========== 确保存储目录存在 ==========
if (!file_exists($storage_path)) {
    mkdir($storage_path, 0755, true);
}

// ========== 日志函数 ==========

2. 修改 Nginx 伪静态文件

修改该站点伪静态规则，加入以下链接重写规则

# 为 /fcircle/page/1 格式的 URL 添加重写规则
rewrite ^/fcircle/page/([0-9]+)/?$ /index.php?pagename=fcircle&rss_page=$1 last;

注意：其中的 fciecle 为友链文章页面设置的 Permalink
