Using HubL code for multiple topics in RSS feed

[LaurenO]

Hi all, 

I'm trying to figure out how to build an RSS feed using the HubL coding so I can pull in two topics from my blog. 

1. Main topic > Parts

2.  Secondary topic > C-arm 

Therefore, it will pull in the PARTS articles and from the 'parts' articles, it will pull in anything labeled under the topic C-ARM. 

Is this possible? If so, how is it possible?

Thank you!

Hey Lauren, 

You can pull posts from a topic using blog_recent_topic_posts, so the below would get the posts from topic1 and topic2 respectively:

{% set topic1_posts = blog_recent_topic_posts('default', 'topic1', 5) %}
{% set topic2_posts = blog_recent_topic_posts('default', 'topic2', 5) %}

You should then be able to combine the two lists: 

{% set combined_topics = topic1_posts + topic2_posts %}

And can work with the combined_topics list, e.g.: 

{% for post in combined_topics %}
  <div class="post-title">{{ post.name }}</div>
{% endfor %}

EDIT: this post has similar code to the above but with more detail (and the sort filter).

I hope that helps!

Thank you, Stephanie. You answered what I asked, but I didn't make my original question very clear.

It makes sense that you can bring in two different topics of blog posts. Now, can it go one step farther?

For instance

Step 1:  Bring all blogs relating to the 'Imaging Equipment Parts' topic

Step 2: Put another filter on step 1 = Filter the 'Imaging Equipment Parts' topic on another topic, 'C-Arms'. 

Therefore, the RSS feed will have only 1 listing - only blog posts that have both 'Imaging Equipment Parts' and 'C-Arms' in the topics tag. 

Is that possible?
