Creating a multi-channel RSS Feed

Question

I am trying to get a multi-channel RSS feed working. The feed seems to populate correctly if I use: <link>{title_permalink="site/index"}</link>, but as you can guess then each article just takes the subscriber to the index of the site.

I tried <link>{title_permalink="{page_url}"}</link>, but that broke the feed completely and it wouldn't populate.

How do I get it so that each entry in the feed links directly to the specific content item, regardless of channel?

My full XML code is here:

{preload_replace:master_channel_name="articles|blogs|news|reports"}
{preload_replace:master_channel_status="OPEN"}
{preload_replace:master_rss_uri="https://ntecheresearch.com/rss/content"}

{exp:rss:feed channel="{master_channel_name}" status="{master_channel_status}"}
<?xml version="1.0" encoding="{encoding}"?>
<rss version="2.0"
    xmlns:dc="https://purl.org/dc/elements/1.1/"
    xmlns:atom="https://www.w3.org/2005/Atom">
    <channel>
    <title>{exp:xml_encode}n-tech Rearch RSS Feed{/exp:xml_encode}</title>
    <link>{channel_url}</link>
    <description></description>
    <dc:language>{channel_language}</dc:language>
    <dc:creator>{email}</dc:creator>
    <dc:rights>Copyright {gmt_date format="%Y"}</dc:rights>
    <pubDate>{gmt_date format="%D, %d %M %Y %H:%i:%s %T"}</pubDate>
    <atom:link href="{master_rss_uri}" rel="self" type="application/rss+xml" />   
{exp:channel:entries channel="{master_channel_name}" limit="30" rdf="off" dynamic_start="on" disable="member_data|trackbacks" status="{master_channel_status}"}
    <item>
      <title>{exp:xml_encode protect_entities="yes"}{title}{/exp:xml_encode}</title>
      <link>{title_permalink="{page_url}"}</link>
      <guid isPermaLink="false">{title_permalink="site/index"}#id:{entry_id}#date:{gmt_entry_date format="%H:%i"}</guid>
      <description><![CDATA[{summary}]]></description>
      {categories}<category>{exp:xml_encode protect_entities="yes"}{category_name}{/exp:xml_encode}</category>
      {/categories}
      <pubDate>{gmt_entry_date format="%D, %d %M %Y %H:%i %T"}</pubDate>
    </item>
{/exp:channel:entries}
    </channel>
</rss>
{/exp:rss:feed}

Answer 1

<link>{title_permalink="{page_url}"}</link> will never work because the title_permalink will be parsed before page_url. page_url also just works on Page Module.

It looks like the channels you're trying to add to the feed use different templates, which makes impossible to use the {url_title_path=""}. Is it?

If so, you have two options.

first one

You can use {relative_url}, which returns the value of the Channel URL on its settings.

For each <item>, use:

<link>{relative_url}/{url_title}</link>

Or, if you're using root relative links on channels settings, which I prefer:

<link>{site_url}{relative_url}/{url_title}</link>

second one

Conditionals! Check for the channel_short_name:

{if channel_short_name == "x"}
    <link>{title_permalink='x_template_group'} [...]
{if:else}
    <link>{title_permalink='y_template_group'} [...]
{/if}
