Wordpress rest API自定义端点，使用Jquery .getJSON模板文字，只有一个项目不显示的问题。

Question

因此，为了进一步深入了解我的标题，我目前正试图通过我在wordpress rest API中创建的自定义端点来显示。我能够检索到我所需要的东西，除了有一部分总是出现未定义。我相信我只是输入了我认为正确的语法，但每次都会导致未定义的结果。这里是自定义端点，用于从邮递员那里搜索查询一个位置。我试图从JSON翻译到模板文字的代码是gallery部分，我将在下面的代码部分后对其进行更多评论。

现在，这里是我写的代码，以显示在我的页面上的div。

    $menuPosts =  $("#search-section");
    $('.getResults').on("click", function(e) {
      //console.log("im clicked");
      //console.log($(this).prop("value"));
      $.getJSON('http://olson-landscaping.local/wp-json/wp/v1/projects?s=' + $(this).prop("value"), posts => {
        $menuPosts.html(`
          ${posts.map(item => `


            <div class="projectFeaturedImage" style="background-image:url(${item.image});"></div>

            <p class="projectTitle">${item.post_title}</p>

            <div class="projectDescription">
              <div class="projectDescription__top">
                <div class="projectDescription__title">
                  <p>project profile</p>
                  <img src="https://olson-landscaping.flywheelsites.com/wp-content/themes/olson/resources/images/logoGreenSmall.png">
                  <p>form o.l. 1298_1</p>
                </div><!-- projectDescription__title close -->

                <div class="projectDetails">
                  <div class="projectDetail">
                  <p class="projectDetail__title">Title</p>
                  <p class="projectDetail__content">${item.post_title}</p>
                  </div>
                  <div class="projectDetail">
                  <p class="projectDetail__title">Acreage</p>
                  <p class="projectDetail__content">${item.acf.acreage}</p>
                  </div>
                  <div class="projectDetail">
                  <p class="projectDetail__title">Completed</p>
                  <p class="projectDetail__content">${item.acf.completed}</p>
                  </div>
                  <div class="projectDetail">
                  <p class="projectDetail__title">Days of Sun</p>
                  <p class="projectDetail__content">${item.acf.days_sun}</p>
                  </div>
                </div>

                <div class="projectContent">
                  <p class="projectDetail__title">Project Notes</p>
                  ${item.post_content}
                </div>

              </div>
              <div class="projectDescription__bottom">scroll for more <img src="https://olson-landscaping.flywheelsites.com/wp-content/themes/olson/resources/images/arrowUp.png"></div>
            </div>

            <div class="projectFeaturedImage projectGallery" style="background-image:url(${item.gallery.full_image_url});"></div>
            <div class="projectEnd"><p>the end</p></div>


          `).join('')}
        `);
      });

    }); //json request close

另外还有一点，这是我的functions.php代码，用于添加自定义端点，不知道这是否会对改变画廊端点的输出有帮助。

function project_endpoint( $request_data ) {
// setup query argument
$args = array(
'post_type' => 'project',
'posts_per_page'=> -1,
'numberposts'=> -1,
's' => $request_data['s'],
);

// get posts
$posts = get_posts($args);

// add custom field data to posts array
foreach ($posts as $key => $post) {
$posts[$key]->acf = get_fields($post->ID);
$posts[$key]->link = get_permalink($post->ID);
$posts[$key]->image = get_the_post_thumbnail_url($post->ID);
$posts[$key]->gallery = acf_photo_gallery('gallery', $post->ID);
}


return $posts;
}

// register the endpoint
add_action( 'rest_api_init', function () {
register_rest_route( 'wp/v1', '/projects/', array(
'methods' => WP_REST_Server::READABLE,
'callback' => 'project_endpoint',
)
);
});

除了最后一个div的底部的画廊部分，所有的东西都完美地出来了。"projectFeaturedImage" 随着 ${item.gallery.full_image_url}

另外，我希望每篇文章都能显示每张图片，而不是只显示这个例子中的三张图片之一。

谁能帮我找到正确的语法？我也可以用PHP写出来，但我真的希望这是一个ajax，而不是一个动画来让每个人在页面上。任何帮助都是非常感激的。谢谢你的帮助
