使用ACF在自定义wordpress页面模板中显示单个帖子内容

Question

我已经创建了一个自定义字段，允许我从站点中的各个帖子中进行选择。导出的acf xml

<title>Posts to page</title>
        <link>http://wp.wafisherinteractive.com/nabc/?acf=acf_posts-to-page</link>
        <pubDate>Wed, 01 Nov 2017 16:41:44 +0000</pubDate>
        <dc:creator>XXXX</dc:creator>
        <guid isPermaLink="false">XXXXXXXXXXX</guid>
        <wp:post_id>6505</wp:post_id>
        <wp:post_date>2017-11-01 11:41:44</wp:post_date>

        </wp:postmeta>
    </item>

我希望能够选择一篇文章，并在新页面上分配该内容。我将自定义字段的范围限定为自定义页面模板

<?php 

/* Template Name: Single Post */

get_header(); ?>



    <div class="row">
        <div class="large-12 columns">  

                <?php

                /*
                *  Loop through post objects (assuming this is a multi-select field) ( setup postdata )
                *  Using this method, you can use all the normal WP functions as the $post object is temporarily initialized within the loop
                *  Read more: http://codex.wordpress.org/Template_Tags/get_posts#Reset_after_Postlists_with_offset
                */

                $post_objects = get_field('post_objects');

                if( $post_objects ): ?>
                    <ul>
                    <?php foreach( $post_objects as $post): // variable must be called $post (IMPORTANT) ?>
                        <?php setup_postdata($post); ?>
                        <li>
                            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
                            <span>Post Object Custom Field: <?php the_field('post_to_page'); ?></span>
                        </li>
                    <?php endforeach; ?>
                    </ul>
                    <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
                <?php endif;

                /*
                *  Loop through post objects (assuming this is a multi-select field) ( don't setup postdata )
                *  Using this method, the $post object is never changed so all functions need a seccond parameter of the post ID in question.
                */

                $post_objects = get_field('post_objects');

                if( $post_objects ): ?>
                    <ul>
                    <?php foreach( $post_objects as $post_object): ?>
                        <li>
                            <a href="<?php echo get_permalink($post_object->ID); ?>"><?php echo get_the_title($post_object->ID); ?></a>
                            <span>Post Object Custom Field: <?php the_field('post_to_page', $post_object->ID); ?></span>
                        </li>
                    <?php endforeach; ?>
                    </ul>
                <?php endif;

                ?>

        </div>
    </div>

<?php get_footer(); ?>

所以当我用这个模板创建一个新页面时，我可以根据标题选择一个帖子

但是那篇文章的内容不会显示。

在您发布的示例中，您没有将内容写入页面的任何位置。有一个模板标签，也被称为“内容”
