typecho常用文章数据调用方法，汇总整理
此文章内包括typecho热门文章调用，热评文章调用，随机调用，字数排行，根据指定id调用，调用相关文章，根据分类调用，以及根据标签调用的方法，看起来是不是特别的全，基本汇总了网上所有的方法，不过值得一提的是，我提供的方法自由度更高，而不是直接像常用的那样，把html的标签代码都写在了function.php里面。好吧，我承认是之前写过一篇这样的文章，typecho二级开发实例，新增Widget接口，然后看到qq爹博客大佬里一篇这样的文章，Typecho自定义调用如热门文章随机文章等，顿时觉得惊为天人，原来wdget也是可以直接在function，php里面定义的。于是这篇文章就诞生了，做个汇总也好，以后开发模板直接来复制。
部分内容直接复制的泽泽博客，望大佬海量。调用热评文章：class Widget_Contents_Post_Comments extends Widget_Abstract_Contents
{
public function execute()
{
$this->parameter->setDefault(array('pageSize' => $this->options->postsListSize));
$this->db->fetchAll($this->select()
->where('table.contents.status = ?', 'publish')
->where('table.contents.created < ?', $this->options->time)
->where('table.contents.type = ?', 'post')
->order('commentsNum', Typecho_Db::SORT_DESC)
->limit($this->parameter->pageSize), array($this, 'push'));
}
}前台模板写法：<?php $this->widget('Widget_Contents_Post_Comments','pageSize=10')->to($Comments);while($Comments->next()): ?>
循环内代码
<?php endwhile; ?>
调用热门文章（注意先实现阅读量功能）：class Widget_Post_hot extends Widget_Abstract_Contents
{
public function __construct($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'));
}
}
前台模板写法：<?php $this->widget('Widget_Post_hot@hot', 'pageSize=6')->to($hot);while($hot->next()): ?>
循环内代码
<?php endwhile; ?>调用随机文章：class Widget_Contents_Post_Rand extends Widget_Abstract_Contents
{
public function execute()
{
$this->parameter->setDefault(array('pageSize' => $this->options->postsListSize));
$this->db->fetchAll($this->select()
->where('table.contents.status = ?', 'publish')
->where('table.contents.created < ?', $this->options->time)
->where('table.contents.type = ?', 'post')
->order('RAND()', Typecho_Db::SORT_DESC)
->limit($this->parameter->pageSize), array($this, 'push'));
}
}
```
前台模板写法：
```
<?php $this->widget('Widget_Contents_Post_Rand','pageSize=10')->to($Rand);while($Rand->next()): ?>
循环内代码
<?php endwhile; ?>
```
根据字数调用：
```
class Widget_Contents_Post_Size extends Widget_Abstract_Contents
{
public function execute()
{
$this->parameter->setDefault(array('pageSize' => $this->options->postsListSize));
$this->db->fetchAll($this->select()
->where('table.contents.status = ?', 'publish')
->where('table.contents.created < ?', $this->options->time)
->where('table.contents.type = ?', 'post')
->order('LENGTH(text)', Typecho_Db::SORT_DESC)
->limit($this->parameter->pageSize), array($this, 'push'));
}
}
```
前台模板写法：
```
<?php $this->widget('Widget_Contents_Post_Size','pageSize=10')->to($Size);while($Size->next()): ?>
循环内代码
<?php endwhile; ?>
```
调用指定文章：
```
class Widget_Post_fanjubiao extends Widget_Abstract_Contents
{
public function __construct($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'));
}
}
```
前台模板写法：
```
<?php $week1="728,1197";
$this->widget('Widget_Post_fanjubiao@fanjubiao', 'fanjubiao='.$week1)->to($fanju);while($fanju->next()): ?>
循环内代码
<?php endwhile; ?>
```
调用相关文章（文章详情页面使用）
```
<?php $this->related(6)->to($relatedPosts); ?>
循环内代码
<?php endwhile; ?>
```
根据分类调用文章：
```
<?php $this->widget('Widget_Archive@index1', 'pageSize=5&type=category', 'mid=分类ID')->to($categoryPosts);while($categoryPosts->next()):?>
循环内代码
<?php endwhile;?>
```
根据标签调用：
```
<?php $this->widget('Widget_Archive@indexessence', 'pageSize=2&type=tag', 'slug=精华')->to($indexessence);while($indexessence->next()): ?>
循环内代码
<?php endwhile; ?>
```
