您好，我已经创建了自定义帖子类型和自定义分类法。自定义帖子类型页面名为page portfolio。php。我在其中创建了一个循环，我试图链接到每个帖子的单个页面。为此，我创建了一个单一投资组合模板。php，但由于某种原因，当我单击永久链接时，我会被发送到404。php页面。这是我的整个结构代码：

//custom post type and taxonomy declaration
<?php

add_action(\'init\' , \'portfolio_manager\');

function portfolio_manager(){
    $args = array(
            \'label\' => \'Portfolio Manager\',
            \'singular_label\' => \'Portfolio Manager\',
            \'public\' => true,
            \'show_ui\' => true,
            \'capability_type\' => \'post\',
            \'hierarchical\' => false,
            \'supports\' => array(\'title\' , \'editor\' , \'thumbnail\'),
            \'rewrite\' => array(
                \'slug\' => \'portfolio\',
                \'with_front\' =>false
            )
    );
    register_post_type(\'portfolio\' , $args);
}

add_action(\'init\' , \'portfolio_taxonomy\');

function portfolio_taxonomy(){
    register_taxonomy("portfolio-type", 
                      array("portfolio"),
                      array("hierarchical" => true, 
                                "label" => "Portfolio Types",
                                "singular_label" => "Portfolip Type", 
                                "rewrite" => true, 
                                "slug" => \'portfolio-type\'
                                )
                     );
}
?>
//page-portfolio.php loop
$portfolio = new WP_Query(array(
                        \'post_type\'=>\'portfolio\',
                        \'posts_per_page\'=>\'-1\'
                    ));
                    while($portfolio->have_posts()): $portfolio->the_post();
                     global $post;
                 ?>
                 <li class ="item" data-type="<?php echo str_replace(" " , "" , strip_tags(get_the_term_list($post->ID, \'portfolio-type\' , \'\' , \'\' , \'\'))); ?>" data-id="id-<?php the_ID(); ?>">
                            <span><a href="<?php the_permalink(); ?>">Details</a></span>
                      <?php
                        endif
                      ?> 
                 </li>

                 <?php
                     endwhile;
                 ?>       

如果是单一投资组合。php不是我应该为这个页面创建的页面模板，那么什么是corect模板？

如果是单一投资组合。php是corect模板，那么我在这里做错了什么呢。为什么permalink不让我单身呢。文件夹php？
