开头

可以在Typecho博客上展示当前文章日期在过去几年的今天所发的其他文章
之前在一些博客上看到这个那年今日,感觉还不错,就借鉴了一下,并进行优化处理,且兼容了sqlite。

代码

  1. 将以下代码放入functions.php

    function historyToday($created)
    {
     $date = date('m/d', $created);
     $date_m = date('m月', $created);
     $date_d = date('d日', $created);
     $time = time();
     $db = Typecho_Db::get();
     $prefix = $db->getPrefix();
     $limit = 5;//显示多少篇文章
      $adapter = $db->getAdapterName();
      if ("Pdo_SQLite" === $adapter || "SQLite" === $adapter) {
     $sql = "SELECT * FROM `{$prefix}contents` WHERE strftime('%m-%d',datetime(datetime(created, 'unixepoch'))) = '{$date}' and created <= {$time} and created != {$created} and type = 'post' and status = 'publish' and (password is NULL or password = '') LIMIT ".$limit;
      }
      if ("Pdo_Mysql" === $adapter || "Mysql" === $adapter || "Mysqli" === $adapter) {
           $sql = "SELECT * FROM `{$prefix}contents` WHERE DATE_FORMAT(FROM_UNIXTIME(created), '%m/%d') = '{$date}' and created <= {$time} and created != {$created} and type = 'post' and status = 'publish' and (password is NULL or password = '') LIMIT ".$limit;
      }
     $result = $db->query($sql);
     $historyTodaylist = [];
     if ($result instanceof Traversable) {
             foreach ($result as $item) {
                 $item = Typecho_Widget::widget('Widget_Abstract_Contents')->push($item);
                 $title = htmlspecialchars($item['title']);
             $permalink = $item['permalink'];
             $date = date('Y年m月d日',$created);
             $historydate = date('Y年m月d日',$item['created']);
                 $historyTodaylist[] = array(
                     "title" => $title,
                     "permalink" => $permalink,
                     "date" => $historydate
                 );
     }
     }
      if (count($historyTodaylist) > 0){
       echo "<div class='bs-today'>
     <fieldset>
         <legend><h5>那年今日</h5></legend>
         <div class='today-date'><div class='today-m'>{$date_m}</div><div class='today-d'>{$date_d}</div></div><ul>
         ";
         foreach ($historyTodaylist as $item){
             echo "<li><span>{$item['date']}</span><a href='{$item['permalink']}' title='{$item['title']}' target='_blank'>{$item['title']}</a></li>";
         }
         echo "</ul></fieldset></div>";
      }
    }
  2. 在文章页面合适的地方插入如下代码:

    <?php historyToday($this->created)?>

这样就大功告成了

总结

仅展示PHP部分,至于样式则可以自己写,这里就不过多讲述
