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
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'>{$item['title']}</a></li>"; } echo "</ul></fieldset></div>"; } }
在文章页面合适的地方插入如下代码:
<?php historyToday($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!
