博客文章的自定义页面模板只显示空白屏幕

Custom Page Template for Blog Posts just show blank screen

我正在构建一个 wordpress 主题,它使博客文章的自定义页面模板在测试时只显示空白屏幕。您可以查看以下脚本:

blog.php

<

?php
/**
 * The main template file.
 *
 * This is the most generic template file in a WordPress theme
 * and one of the two required files for a theme (the other being style.css).
 * It is used to display a page when nothing more specific matches a query.
 * E.g., it puts together the home page when no home.php file exists.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package testing
 */

/*
Template Name: blog
*/

get_header(); ?>

    <div id="primary" class="content-area">
        <main id="main" class="site-main" role="main">

        <?php if ( have_posts() ) : ?>

            <?php if ( is_home() && ! is_front_page() ) : ?>
                <header>
                    <h1 class="page-title screen-reader-text"><?php single_post_title(); ?></h1>
                </header>
            <?php endif; ?>


            <?php /* Start the Loop */ ?>
            <?php while ( have_posts() ) : the_post(); ?>

                <?php

                    /*
                     * Include the Post-Format-specific template for the content.
                     * If you want to override this in a child theme, then include a file
                     * called content-___.php (where ___ is the Post Format name) and that will be used instead.
                     */
                    get_template_part( 'template-parts/content', get_post_format() );
                ?>

            <?php endwhile; ?>

            <?php the_posts_navigation(); ?>

        <?php else : ?>

            <?php get_template_part( 'template-parts/content', 'none' ); ?>

        <?php endif; ?>

        </main><!-- #main -->
    </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

如何在自定义模板页面上显示博文?

我用自己制作的wordpress主题this generator

将代码行放在 while 循环之前。

<?php query_posts('post_type=post&post_status=publish&posts_per_page=10&paged='. get_query_var('paged')); 
?>
