Here is the for the above question, hope this helps someone in the future.

您将添加过滤器:

• 在传递给过滤器的函数中，您需要将 CONTEXT 变量设置为运行所有魔法的函数
• 然后返回 CONTEXT，以便您可以自行决定在整个网站中使用它

代码示例:

add_filter( 'timber_context', 'fancySquares_show_instagram_results'  );

function fancySquares_show_instagram_results( $context ) {
    $context['fancySquaresInstagram'] = fancySquares_get_instagram();
    return $context;
}


function fancySquares_get_instagram()
{
  if(get_transient('instagram')) 
    {
        return get_transient('instagram');
    } 
    else 
    {
      $api = wp_remote_request("instagram-api-url");
      $api = json_decode($api['body']);
      $images = [];

      for($i = 0; $i < 20; $i++)
      {
        $images[$i] = [];
        $images[$i]['image'] = $api->data[$i]->images->standard_resolution->url;
        $images[$i]['url'] = $api->data[$i]->link;
        $images[$i]['likes'] = $api->data[$i]->likes->count;
      }


        set_transient('instagram', $images, 60*60*24); // expires every day
        return $images;
    }

}

然后您将输出:

{% for insta in fancySquaresInstagram %}

    {{insta['url']}}

  {% endfor %} 

或者可以打印整个内容以更好地了解里面的内容:

or could print the whole thing to get a better idea of whats inside:

{{ fancySquaresInstagram|print_r }}
