实现wordpress路由功能,该怎么处理

//add query_args
function add_query_vars($aVars) {
	$aVars[] = 'score';
	$aVars[] = 'type'; // represents the name of the product category as shown in the URL
	return $aVars;
}
add_filter('query_vars', 'add_query_vars');//wordpress过滤器

$type=isset($wp_query->query_vars['type'])?urldecode($wp_query->query_vars['type']):'';

//路由规则-根据时间排序以及各类别的最新条目
function add_rewrite_rules($aRules) {
	$aNewRules = array(
		'text/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$' => 'index.php?cat=2&score=$matches[1]&paged=$matches[3]',
		'image/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&score=$matches[1]&paged=$matches[3]',
		'video/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&score=$matches[1]&paged=$matches[3]',
		'resource/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=5&score=$matches[1]&paged=$matches[3]',
		'text/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=2&type=$matches[1]&paged=$matches[3]',
		'image/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&type=$matches[1]&paged=$matches[3]',
		'video/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&type=$matches[1]&paged=$matches[3]',
		'resource/(latest)/?$'=>'index.php?cat=5&type=$matches[1]',
		'(month)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',
		'(24hr)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',
	);
	$aRules = $aNewRules + $aRules;
	return $aRules;
}
add_filter('rewrite_rules_array', 'add_rewrite_rules');

//路由规则-类别
add_rewrite_rule('^text/?(/page/([0-9]+)?)?/?$','index.php?cat=2&paged=$matches[2]','top'); //http://www.ke6.com/text/ 段子对应的类别ID
add_rewrite_rule('^image/?(/page/([0-9]+)?)?/?$','index.php?cat=3&paged=$matches[2]','top'); //http://www.ke6.com/image/ 趣图对应的类别ID
add_rewrite_rule('^video/?(/page/([0-9]+)?)?/?$','index.php?cat=4&paged=$matches[2]','top'); //http://www.ke6.com/video/ 视频对应的类别ID
add_rewrite_rule('^resource/?(/page/([0-9]+)?)?/?$','index.php?cat=5&paged=$matches[2]','top'); //http://www.ke6.com/resource/ 视频对应的类别ID
