Question

我有一项有趣的任务。我为wordpress编写了自定义404处理程序并提取了一个URL。在做了一些逻辑后，我有一个wordpress帖子ID，我需要显示而不是404页面。

如何显示wordpress帖子页面而不是404页面？我唯一能想到的就是做

TypeError: Cannot set property 'route' of null

    at restangularizeElem (http://localhost:8080/Students/app/lib/restangular.js:788:35)

但有没有其他方法可以做到这一点？感谢

我无法通过重写模板的404.php来做到这一点。而且我认为那将是模板依赖的。相反，我设法使用template_redirect操作显示帖子。插件函数的代码如下所示：

    function func_404_redirect($query){
        global $wp_query;
        $post = get_post(2);
        $wp_query->queried_object = $post;
        $wp_query->is_single = true;
        $wp_query->is_404 = false;
        $wp_query->queried_object_id = $post->ID;
        $wp_query->post_count = 1;
        $wp_query->current_post=-1;
        $wp_query->posts = array($post);
    }
    add_filter('template_redirect','func_404_redirect');

我在主题中使用的代码：

<?php
global $my_theme;
$content_id = $my_theme->option( OPT_GENERAL, '404_page_id', TRUE );
$my_theme->prepare( $content_id, '404' );
get_header();
?>
<!-- [BEGIN 404] -->
<div class="row">
    <?php
        get_sidebar( 'left' );
    ?>
    <div id="primary" class="content-area <?php echo $class; ?>">
        <main id="main" class="site-main" role="main">
            <section class="error-404 not-found">
                <?php
                // Load the content from the selected page
                    $content_loaded = FALSE;
                    if( $content_id > 0 )
                    {
                        $query = new WP_Query( array( 'page_id' => $content_id ) );
                        while( $query->have_posts() )
                        {
                            $query->the_post();
                            get_template_part( 'content', 'page' );
                            $content_loaded = TRUE;
                        }
                        wp_reset_postdata();
                    }
                // Fallback content
                    if( !$content_loaded )
                    {
                ?>
                <header class="page-header">
                    <h4 class="page-title well text-center"><?php _e( 'Page not found', 'my_theme' ); ?></h4>
                </header>
                <div class="page-content alert alert-danger text-center">
                    <p><?php _e( 'It looks like nothing was found at this location', 'my_theme' ); ?></p>
                </div>
                <?php
                    }
                ?>
            </section>
        </main>
    </div>
    <?php get_sidebar( 'right' ); ?>
</div>
<?php get_footer(); ?>
<!-- [END 404] -->

您可以在主题（或儿童）中创建404.php页面而不是404处理程序，请参阅reference - 从那里您可以执行任何您喜欢的操作：加载帖子列表，加载单个帖子等等。
