经过几周的摆弄和各种各样的把戏，我终于明白了。有两件事我做错了，我希望wordpress能够访问位于斜杠之间的最后两个值作为get参数/examentraining/vak/VAKNAME/LEVELNAME/ 已提交给Wordpress。p=1316&vakname=VAKNAME&level=LEVELNAME => /examentraining/vak/VAKNAME/LEVELNAME/ 是不正确的，因为它起到了相反的作用。但当我改变重写规则时，它仍然不起作用。

我仍然需要找出确切的原因，但我从来没有设法通过。htaccess文件。然后我遇到了Kyle E Gentile的以下课程。

<?php
/*
//Author Kyle E Gentile
//To use this class you must first include the file.  
//After including the file, you need to create an options array.  For example:
$options = array(
    \'query_vars\' => array(\'var1\', \'var2\'),
    \'rules\' => array(\'(.+?)/(.+?)/(.+?)/?$\' => \'index.php?pagename=$matches[1]&var1=$matches[2]&var2=$matches[3]\')
);
//After creating our $option array, 
//we will need to create a new instance of the class as below:
$rewrite = new Add_rewrite_rules($options);
//You must pass the options array, this way. (If you don\'t there could be problems) 
//Then you can call the filters and action functions as below:
add_action(\'wp_head\', array(&$rewrite, \'flush_rules\'));
add_action( \'generate_rewrite_rules\', array(&$rewrite, \'add_rewrite_rules\') );
add_filter( \'query_vars\', array(&$rewrite, \'add_query_vars\') );
//That is it.
*/

//prevent duplicate loading of the class if you are using this in multiply plugins
if(!class_exists(\'add_rewrite_rules\')){

    class Add_rewrite_rules{

        var $query_vars;
        var $rules;

        function __construct($options){
            $this->init($options);
        }

        function init($options){
            foreach($options as $key => $value){
                $this->$key = $value;
            }
        }

        function rules_exist(){
            global $wp_rewrite;

            $has_rules = TRUE;

            foreach($this->rules as $key => $value){
                if(!in_array($value, $wp_rewrite->rules)){
                    $has_rules = FALSE;
                }   
            }

            return $has_rules;
        }

        //to be used add_action with the hook \'wp_head\'
        //flushing rewrite rules is labor intense so we better test to see if our rules exist first
        //if the rules don\'t exist flush its like after a night of drinking  
        function flush_rules(){
            global $wp_rewrite;

            if(!$this->rules_exist()){
                //echo "flushed"; // If want to see this in action uncomment this line and remove this text and you will see it flushed before your eyes
                $wp_rewrite->flush_rules();
            }
        }

        //filter function to be used with add_filter() with the hook "query_vars"
        function add_query_vars($query_vars){

            foreach($this->query_vars as $var){
                $query_vars[] = $var;
            }

            return $query_vars;
        }

        //to be used with a the add_action() with the hook "generate_rewrite_rules"
        function add_rewrite_rules(){
            global $wp_rewrite;

            $wp_rewrite->rules = $this->rules + $wp_rewrite->rules;
        }

    }

}
?>

我在插件的init中添加了以下函数。

public function rewriteRules()
{
//Add the query variables to the list so wordpress doesn\'t discard them or worse use them to try and find by itself what page to serve.
    $options = array(
        \'query_vars\' => array(\'trainingid\', \'vakname\'),
        \'rules\' =>
            array( \'uncategorized/vak/([^/]+)/([^/]+)/?$\' => \'index.php?p=1316&vakname=$matches[1]&level=$matches[2]\'
            )
    );

    //I use a autoloader but if you don\'t you have to include the class.
    //include_once(\'path/to/AddRewriteRules.php\');
    $rewrite = new AddRewriteRules($options);
    add_action(\'wp_head\', array(&$rewrite, \'flush_rules\'));
    add_action(\'generate_rewrite_rules\', array(&$rewrite, \'add_rewrite_rules\'));
    add_filter(\'query_vars\', array(&$rewrite, \'add_query_vars\'));


}

这解决了问题，但在这之前还有一步，你可能已经注意到我想要匹配examentraining/vak/VAKNAME/LEVELNAME/ 但我最终匹配了uncategorized/vak/VAKNAME/LEVELNAME/. 这是因为出于某种原因，Wordpress SEO或Wordpress本身会干扰我的请求。要找到正确的请求URL，请使用debug bar plugin. 它准确地告诉您将收到什么请求，以及符合哪些规则。

我希望这对任何人都有帮助！
