Summary of Changes

Fixed the tag feed (RSS) to properly respect the Show Intro Text article parameter when displaying content items.

File changed: components/com_tags/views/tag/FeedView.php

What was changed:

The tag feed previously used only core_body from the UCM content table, which contains only the intro text. Full text after Read More was completely missing from the feed.

The fix:

1. Detects when a tagged item is a Joomla article (com_content.article)
2. Pre-fetches fulltext and attribs from the #__content table for all articles in a single optimized query
3. Parses article parameters from attribs to determine the show_intro setting
4. Builds the feed description based on:
   • feed_summary (com_content parameter: 0 = intro only, 1 = full text)
   • show_intro (article parameter: 1 = show intro, 0 = hide intro)
5. Falls back to the global com_content show_intro setting if not set at article level

Testing Instructions

Prerequisites:

• Joomla 5.4 or later
• A tag created (e.g., "TestTag")
• A Tagged Items menu item created for that tag
• RSS feeds enabled

Step 1: Configure Article Options

1. Log in to Joomla Administrator
2. Navigate to Content → Articles → Options
3. Click the Articles tab
4. Set Show Intro Text to Hide
5. Click the Integration tab
6. Set Include in Feed to Full Text
7. Click Save & Close

Step 2: Create an article with Read More and assign a tag

1. Navigate to Content → Articles
2. Click New
3. Title: "Tags RSS Feed Test"
4. In the content area:
   • Type "AA" (intro text)
   • Click the Read More toggle (CMS Content → Read More)
   • After the read more break, type "BB" (full text)
5. In the Tags field, select a tag (e.g., "TestTag")
6. Click Save & Close

Step 3: Create a Tagged Items menu item (if not already exists)

1. Navigate to Menus → Main Menu
2. Click New
3. Menu Title: "Tags RSS Feed Test Menu"
4. Menu Item Type: Click Select → under Tags → Tagged Items
5. Tags: Select your test tag (e.g., "TestTag")
6. Click Save & Close

Step 4: Access the RSS feed

Use the URL of your tagged items menu item with feed parameters:

http://localhost/tags-rss-feed-test-menu?format=feed&type=rss

Or use the direct route:

http://localhost/index.php?option=com_tags&view=tag&id=XX&format=feed&type=rss

Step 5: Observe the feed output

Look at the <description> tag of your article in the feed.

Actual result BEFORE applying this Pull Request

<description><![CDATA[<p>AA</p>]]></description>

Only the intro text (AA) appears. The full text (BB) is completely missing from the feed.

Expected result AFTER applying this Pull Request

<description><![CDATA[<p>BB</p>]]></description>

Only the full text (BB) appears. The intro text (AA) is correctly hidden because Show Intro Text = Hide.

Additional verification

Test with Show Intro Text = Show:

1. Change Show Intro Text back to Show in Article Options
2. Access the feed again

Expected result:

<description><![CDATA[<p>AA</p><p>BB</p>]]></description>

Both intro text (AA) and full text (BB) appear.

Performance notes

The fix uses a single optimized query to fetch fulltext and attribs for all articles in the feed, regardless of the number of articles. This avoids N+1 query issues and maintains good performance even with larger feed limits.

Additional Notes

• Only com_content.article items are affected by this fix
• Other content types (com_contact, com_newsfeeds, etc.) continue to work as before
• The fix respects both the article-specific show_intro setting and the global com_content default
