自定义标签库（在公共的html）

[php]代码库

一：在配置中载入标签库

	'APP_AUTOLOAD_PATH' => '@.TagLib',
	'TAGLIB_BUILD_IN' => 'Cx,Hd',  //Cx是tp里的核心标签 Hd是自己写的自定义标签名
二：写一个自定义标签类
<?php
import('TagLib');
/*
*自定义标签库
*/
Class TagLibHd extends TagLib{

	Protected $tags =array(
		'nav' => array('attr' => 'limit,order','close' => 1),         //定义属性   close=>1闭合标签  
		'hot' => array('attr' => 'limit','close' => 1),
		'new' => array('attr' => 'limit','close' => 1)
		);

	Public function _nav ($attr,$content) {
		$attr = $this->parseXMLAttr($attr);
		$str = <<<str
<?php
		\$_nav_cate = M('cate')->order("{$attr['order']}")->select();
		import('Class.Category',APP_PATH);
		\$_nav_cate = Category::unlimitedForLayer(\$_nav_cate);
		foreach (\$_nav_cate as \$_nav_cate_v) :
			extract(\$_nav_cate_v);
                        \$url = U('/c_'.$id);

?>
str;
		$str .= $content;
		$str .= '<?php endforeach;?>';
		return $str;
	}

	Public function _hot ($attr,$content) {
		$attr = $this->parseXMLAttr($attr);
		$limit = $attr['limit'];
		$str = <<<str
<?php
		\$field = array('id','title','hits');
		\$_hot_blog = M('blog')->field(\$field)->limit({$limit})->order('hits DESC')->select();
		foreach (\$_hot_blog as \$_hot_value) :
			extract(\$_hot_value);
			\$url = U('/'.\$id);
?>
str;
		$str .= $content;
		$str .= '<?php endforeach;?>';
		return $str;
	}

	Public function _new ($attr,$content) {
		$attr = $this->parseXMLAttr($attr);
		$limit = $attr['limit'];
		$str = <<<str
<?php
		\$field = array('id','title','time','hits');
		\$_hot_blog = M('blog')->field(\$field)->limit({$limit})->order('time DESC')->select();
		foreach (\$_hot_blog as \$_hot_value) :
			extract(\$_hot_value);
			\$url = U('/'.\$id);
?>
str;
		$str .= $content;
		$str .= '<?php endforeach;?>';
		return $str;
	}

}
?>
三：在模板中使用标签
