typecho常用代码记录

最近改typecho特别痛苦，我虽然学过php，那也是十几年前了，现在脑袋空空，看不懂了，只好把要用的记录下来，以备不时之需

Typecho调用分类目录的位置添加以下代码

<?php $this->widget('Widget_Archive@index', 'pageSize=6&type=category', 'slug=缩略码')
->parse('<li><a href="{permalink}">{title}</a></li>'); ?>

调用自定义字段

<?php $this->fields->fieldName ?>
<img  class="tubiao"src="<?php Helper::options()->themeUrl('img/linju.svg'); ?>" alt="邻居">

 <?php
    $period = time() - 999592000; // 999592000秒
    $counts = Typecho_Db::get()->fetchAll(Typecho_Db::get()
    ->select('COUNT(author) AS cnt','author', 'url', 'mail')
    ->from('table.comments')
    ->where('created > ?', $period )
    ->where('status = ?', 'approved')
    ->where('type = ?', 'comment')
    ->where('authorId = ?', '0')
    ->group('author')
    ->order('cnt', Typecho_Db::SORT_DESC)
    ->limit(25)
    );
    $mostactive = '';
    $avatar_path = 'http://www.gravatar.com/avatar/';
    foreach ($counts as $count) {
      $avatar = $avatar_path . md5(strtolower($count['mail'])) . '.jpg';
      $c_url = $count['url']; if ( !$c_url ) $c_url = Helper::options()->siteUrl;
      $mostactive .= "<a href='" . $c_url . "' title='" . $count['author'] . " (参与" . $count['cnt'] . "次互动)' target='_blank'><img src='" . $avatar . "' alt='" . $count['author'] . "的头像' class='avatar' width='32' height='32' /></a>\n";
    }
    echo $mostactive; ?>
