RSS feed from 2.1.4 no longer works with conditionals in 3.2.0

Question

We just upgraded to 3.2.0 from 2.1.4, and the move seems to have broken my RSS feeds completely. I used several conditionals to assign the correct paths to each template group section, but none of those seem to work now. See the following for a representative example – perhaps you can divulge what I need to change for parsing to work in the new EE. (You’re seeing part of code that has worked for eight years until we updated.)

    {preload_replace:master_channel_name="restaurants|arts|community|kids|blogs|rural_road_trips|style|food|parties"}
{exp:rss:feed channel="{master_channel_name}"}

You get the idea… What is going wrong in 3.2.0?

Thanks!

Answer 1

Robin Sowell at EE found the problem, and of course it had to do with parsing -- but was in the last place I would have thought to look!

The long and short of it: We cannot nest {categories} tags any longer and get away with it. Never was a good idea - won't work at all now.

Here is a short example of what DOES work!

    {exp:channel:entries channel="{master_channel_name}" limit="19" rdf="off" dynamic_start="on" status="open" disable="member_data|trackbacks" category_group="1|2|3|4|5|6|7|8|13|14|15"}
    <item>

{categories}
{if channel_id=="12" AND category_id=="16"}

      <title><![CDATA[{title} -- Arts Section -- {category_name} ]]></title>
      <link>{title_permalink=arts_section/arts_articles_movies}</link>
      <guid>{title_permalink=arts_section/arts_articles_movies}</guid>
      <description><![CDATA[{article}]]></description>
      <dc:subject><![CDATA[{category_name}, ]]></dc:subject>
      <dc:date>{gmt_entry_date format="%Y-%m-%dT%H:%i:%s%Q"}</dc:date>
{/if}{/categories}

Now the conditionals work and parse-out just fine. I hope this helps someone else in a similar situation where you need to direct categories to specific template groups and templates.
