实现wordpress路由功能
经过两天的正则表达式的学习，和研究wordpress的路由函数，成功实现了自定义wordpress路由功能，以下是路由规则的实现。
如果有自定义的url参数，要通过路由传递，必须通过wordpress的函数将参数添加进去：
<br />
//add query_args<br />
function add_query_vars($aVars) {<br />
$aVars[] = 'score';<br />
$aVars[] = 'type'; // represents the name of the product category as shown in the URL<br />
return $aVars;<br />
}<br />
add_filter('query_vars', 'add_query_vars');//wordpress过滤器<br />
$type=isset($wp_query->query_vars['type'])?urldecode($wp_query->query_vars['type']):'';
<br />
//路由规则-根据时间排序以及各类别的最新条目<br />
function add_rewrite_rules($aRules) {<br />
$aNewRules = array(<br />
'text/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$' => 'index.php?cat=2&score=$matches[1]&paged=$matches[3]',<br />
'image/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&score=$matches[1]&paged=$matches[3]',<br />
'video/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&score=$matches[1]&paged=$matches[3]',<br />
'resource/([^latest][^/]+)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=5&score=$matches[1]&paged=$matches[3]',<br />
'text/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=2&type=$matches[1]&paged=$matches[3]',<br />
'image/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=3&type=$matches[1]&paged=$matches[3]',<br />
'video/(latest)/?(/page/([0-9]+)?)?/?$'=>'index.php?cat=4&type=$matches[1]&paged=$matches[3]',<br />
'resource/(latest)/?$'=>'index.php?cat=5&type=$matches[1]',<br />
'(month)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',<br />
'(24hr)/?(/page/([0-9]+)?)?/?$'=>'index.php?score=$matches[1]&paged=$matches[3]',<br />
);<br />
$aRules = $aNewRules + $aRules;<br />
return $aRules;<br />
}<br />
add_filter('rewrite_rules_array', 'add_rewrite_rules');<br />
<br />
//路由规则-类别<br />
add_rewrite_rule('^text/?(/page/([0-9]+)?)?/?$','index.php?cat=2&paged=$matches[2]','top'); //http://www.ke6.com/text/ 段子对应的类别ID<br />
add_rewrite_rule('^image/?(/page/([0-9]+)?)?/?$','index.php?cat=3&paged=$matches[2]','top'); //http://www.ke6.com/image/ 趣图对应的类别ID<br />
add_rewrite_rule('^video/?(/page/([0-9]+)?)?/?$','index.php?cat=4&paged=$matches[2]','top'); //http://www.ke6.com/video/ 视频对应的类别ID<br />
add_rewrite_rule('^resource/?(/page/([0-9]+)?)?/?$','index.php?cat=5&paged=$matches[2]','top'); //http://www.ke6.com/resource/ 视频对应的类别ID<br />
