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'));
       $db = Typecho_Db::get();
    }
}

前台调用文章

<?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(); ?>
文章缩略图：<?php $hot->fields->img(); ?>
<!--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'));
    }
}

前台调用

<?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; ?>
