适用于Typecho的那年今日代码 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.phpfunction 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!

typecho 实现“那年今日”功能 经常逛 QQ 空间的人会发现，它就有这个功能。这个功能是展示与今天同一天发生的事、写的文章，上传的图片等等。其实，在之前使用 Wordpress 程序时，我用的知更鸟主题集成了这个功能，他叫历史上的今天。改用了 typecho 程序后，JOE主题的作者不断加强主题，而这个"那年今日"的功能也在网友提出建议后如约而至了。作者只是写好了函数，前端并没有调用，所以也就没有具体的样式。我简单的写了一个样式，把这个功能用起来了，下面我把使用的方法分享一下吧。函数部分function _getHistoryToday($created) { $date = date('m/d', $created); $time = time(); $db = Typecho_Db::get(); $prefix = $db->getPrefix(); $sql = "SELECT * FROM `{$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 5"; $result = $db->query($sql); if ($result instanceof Traversable) { foreach ($result as $item) { $item = Typecho_Widget::widget('Widget_Abstract_Contents')->push($item); $title = htmlspecialchars($item['title']); $permalink = $item['permalink']; echo " <li class='item'> <a class='link' href='{$permalink}' title='{$title}'>{$title}</a> </li> "; } } }前端调用1、 文章页内<?php _getHistoryToday($this->created) ?>2、 全局调用<?php _getHistoryToday(time()) ?>效果查看本站的侧边栏，可以看到。CSS代码：.joe_history{margin:15px 0;padding:15px;position:relative;border:1px dashed var(--classA);line-height:26px}.joe_history .title{position:absolute;top:0;left:15px;font-size:15px;-webkit-transform:translateY(-50%);transform:translateY(-50%);background:var(--background);padding:0 5px;color:var(--main);font-weight:600}.joe_history .title-date{color:var(--theme)}.joe_history .item{display:flex;align-items:center;line-height:30px}.joe_history .item strong{color:var(--routine);margin-right:20px}.joe_history .item .link{position:relative;color:var(--routine);max-width:85%;overflow:hidden;text-overflow:ellipsis;white-space:nowrap}.joe_history .item .link::after{content:'';position:absolute;bottom:0;left:0;width:0;height:1px;background:var(--theme);transition:all 0.35s}.joe_history .item .link:hover{color:var(--theme)}.joe_history .item .link:hover::after{width:100%}.joe_history .item .icon{fill:var(--routine)}侧边栏详细代码，添加到public/aside.php的恰当位置 <section class="joe_aside__item hot"> <div class="joe_aside__item-title"> <svg class="icon" viewBox="0 0 1024 1024" xmlns="http://www.w3.org/2000/svg" width="18" height="18"> <path d="M704 199.68h28.16c25.6 0 46.08-20.48 46.08-43.52V69.12c0-25.6-20.48-43.52-46.08-43.52h-28.16c-25.6 0-43.52 20.48-43.52 43.52v87.04c-2.56 25.6 17.92 43.52 43.52 43.52z m268.8 25.6v-102.4c0-20.48-17.92-38.4-38.4-38.4h-84.48-46.08v56.32c0 51.2-40.96 92.16-92.16 92.16h-5.12c-51.2 0-92.16-40.96-92.16-92.16V84.48h-171.52v56.32c0 51.2-40.96 92.16-92.16 92.16h-5.12c-51.2 0-92.16-40.96-92.16-92.16V84.48H179.2h10.24-99.84C69.12 84.48 51.2 102.4 51.2 122.88v844.8c0 20.48 17.92 38.4 38.4 38.4H184.32h-12.8H844.8h-15.36 97.28c20.48 0 38.4-17.92 38.4-38.4V232.96c7.68-2.56 7.68-5.12 7.68-7.68z m-58.88 663.04c0 53.76-5.12 58.88-58.88 58.88H168.96c-53.76 0-58.88-5.12-58.88-58.88V320h803.84v568.32zM332.8 199.68h28.16c25.6 0 46.08-20.48 46.08-43.52V69.12c0-25.6-20.48-43.52-46.08-43.52H332.8c-25.6 0-46.08 20.48-46.08 43.52v87.04c0 25.6 20.48 43.52 46.08 43.52zM302.08 640h391.68c-12.8 25.6-25.6 48.64-43.52 71.68-15.36 20.48-33.28 38.4-53.76 56.32-20.48 15.36-40.96 30.72-64 43.52-17.92 10.24-35.84 17.92-56.32 25.6-10.24 2.56-12.8 12.8-10.24 23.04 2.56 5.12 5.12 7.68 10.24 10.24 5.12 2.56 10.24 2.56 15.36 0 23.04-7.68 46.08-20.48 69.12-33.28 28.16-15.36 51.2-35.84 76.8-56.32 23.04-23.04 43.52-48.64 64-76.8 15.36-23.04 28.16-48.64 38.4-76.8 5.12-12.8-5.12-25.6-17.92-25.6H537.6v-66.56c0-10.24-7.68-17.92-17.92-17.92-10.24 0-17.92 7.68-17.92 17.92v66.56h-199.68c-10.24 0-17.92 7.68-17.92 17.92v2.56c-2.56 10.24 7.68 17.92 17.92 17.92z m17.92-102.4l74.24-76.8 12.8-12.8c10.24-7.68 17.92-12.8 30.72-15.36 5.12-2.56 12.8-2.56 23.04-2.56h122.88c7.68 0 15.36 0 23.04 2.56 5.12 0 12.8 2.56 17.92 5.12 10.24 5.12 17.92 12.8 25.6 20.48l71.68 76.8c7.68 7.68 17.92 7.68 25.6 0 5.12-5.12 5.12-7.68 5.12-12.8s-2.56-7.68-5.12-12.8L675.84 435.2l-17.92-17.92c-5.12-5.12-12.8-7.68-20.48-12.8-15.36-7.68-35.84-10.24-56.32-10.24h-122.88c-20.48 0-38.4 2.56-56.32 10.24-7.68 5.12-12.8 7.68-20.48 12.8l-17.92 17.92-71.68 76.8c-5.12 5.12-5.12 7.68-5.12 12.8s2.56 10.24 5.12 12.8c7.68 7.68 20.48 7.68 28.16 0z"></path> </svg> <span class="text">那年今日</span> <span class="line"></span> </div> <ol class="joe_aside__item-contain"> <?php _getHistoryToday(time()) ?> </ol> </section>
