Question

我正在尝试使用Wordpress和bootstraps carousal。我创建了一个名为images的自定义帖子类型，并将其链接到我想要的帖子。然后我将图像上传到每个帖子，当我循环播放数组时，它最终会在旋转木马中输出我的所有图像。它意味着遍历我的自定义图像区域中的每个图像，并在旋转木马中回显它们。

它还在我的html页面上输出no-repeat center;">作为纯文本。我不知道为什么

  <?php 
get_header(); 
?>

<?php 

global $wp_query;
$postid = $wp_query->post->ID;
wp_reset_query();

$images = get_post_meta($postid, 'images', false);


?>


<div class="row">
    <div class="col-md-3">
        <div id="page_title">Case Studies</div>
    </div>
    <div class="col-md-9">
        <div id="page_excerpt">
            <div class="vertical_align_centre">
                <?php the_excerpt();?>
            </div>
        </div>
    </div>
</div>

Answer 1

从查询中看，您的数组中的所有帖子都可用。

你可以在顶部解决这个问题：

'numberposts' = 10, //or however many you want

或事后切断数组：

$attachments = array_slice($attachments ,0 ,10);

Answer 2

这就是我理解你的问题的方法。

您制作了一个名为images的自定义帖子类型，并为该帖子类型添加了帖子。那些包含图像的帖子（我假设您正在使用缩略图）。因此，您需要将这些图像用作引导轮播。

如果我在这里就是你的答案。请注意，此代码未经过测试。所以在尝试之前备份你的代码。
