Typecho自定义调用如热门文章随机文章等 Typecho自定义调用这是面向模板开发者的一篇干货文章，通过学习下面的两个事例，你可以通过调整数据库语句来实现自定义调用文章，如随机文章等。调用热门文章在functions.php中加入如下代码class Widget_Post_hot extends Widget_Abstract_Contents { public function __construct($request, $response, $params = NULL) { parent::__construct($request, $response, $params); $this->parameter->setDefault(array('pageSize' => $this->options->commentsListSize, 'parentId' => 0, 'ignoreAuthor' => false)); } public function execute() { $select = $this->select()->from('table.contents') ->where("table.contents.password IS NULL OR table.contents.password = ''") ->where('table.contents.status = ?','publish') ->where('table.contents.created <= ?', time()) ->where('table.contents.type = ?', 'post') ->limit($this->parameter->pageSize) ->order('table.contents.views', Typecho_Db::SORT_DESC); $this->db->fetchAll($select, array($this, 'push')); } }然后在前台调用热门文章时就可以这样写了<?php $this->widget('Widget_Post_hot@hot', 'pageSize=6')->to($hot); ?> <?php while($hot->next()): ?> 文章链接：<?php $hot->permalink() ?> 文章标题：<?php $hot->title(); ?> <!--等等--> <?php endwhile; ?>这种写法非常原生，使用方法也同typecho调用某分类下的文章语法一致调用指定文章集合在functions.php中加入如下代码class Widget_Post_fanjubiao extends Widget_Abstract_Contents { public function __construct($request, $response, $params = NULL) { parent::__construct($request, $response, $params); $this->parameter->setDefault(array('pageSize' => $this->options->commentsListSize, 'parentId' => 0, 'ignoreAuthor' => false)); } public function execute() { $select = $this->select()->from('table.contents') ->where("table.contents.password IS NULL OR table.contents.password = ''") ->where('table.contents.type = ?', 'post') ->limit($this->parameter->pageSize) ->order('table.contents.modified', Typecho_Db::SORT_DESC); if ($this->parameter->fanjubiao) { $fanju=explode(",",$this->parameter->fanjubiao); $select->where('table.contents.cid in ?', $fanju); } $this->db->fetchAll($select, array($this, 'push')); } }然后在前台调用热门文章时就可以这样写了<?php $week1="728,1197";//指定文章id集合多个文章中间用英文逗号隔开 $this->widget('Widget_Post_fanjubiao@fanjubiao', 'fanjubiao='.$week1)->to($fanju); ?> <?php while($fanju->next()): ?> 文章链接：<?php $fanju->permalink() ?> 文章标题：<?php $fanju->title(); ?> <!--等等--> <?php endwhile; ?>这种写法非常原生，使用方法也同typecho调用某分类下的文章语法一致总结这样的写法只要懂得数据库语句，就可以定制各种自己所需的调用文章！语法贴近原生且内部支持调用各种函数，比如缩略图函数等等！来源：泽泽社长https://qqdie.com/archives/typecho-custom-call.html
