Twig 模板中 WCK 自定义字段的 Wordpress、Timber、打印字段

Question

我已经使用字段的 WCK 插件为自定义 post 类型创建了自定义字段，并希望将这些字段添加到我的 Timber Twig 模板中。（我知道 Timber 为此推荐 ACF，但我首先尝试 WCK，因为这是一个非营利性网站，WCK 在其免费插件版本中提供了 ACF 没有的东西）。这是 php 文件的相关行：

$context['home_page_content'] = Timber::get_posts('post_type=vopthomepage');

在我的树枝模板中打印：

{{ dump(home_page_content) }}

我得到的相关部分（我想？）是：

public 'object_type' => string 'post' (length=4)
public 'post_type' => string 'vopthomepage' (length=12)
public 'are_you' => // this is the field group
public 'question_1' => string 'New to the area, looking for a church to join?' (length=46) // this is the field

所以为了获得我试过的字段 {{ post.question_1 }} ，没有快乐，所以然后尝试 {{ post.get_field('question_1') }} 我也尝试按照 ACF 的建议使用 {{ post.meta('are_you').question_1 }} 但 none这些打印页面上的任何内容。

这是完整转储：

Answer 1

您的内容在 home_page_content 中，它是 Timber\Post 个对象的数组。要获取内容，您必须像这样遍历它们：

{% for post in home_page_content  %}
  {{ post.question_1 }}
{% endfor %}

或者，如果您只需要数组中单个特定元素的数据，您可以执行类似

的操作

{{ home_page_content[0].question_1 }}

其中数字（在本例中为 0）指的是您想要的元素。
