Modify WordPress RSS2 Preview

I made an aggregator site weeks a go. One of the aggregated site got lower expectation. I think it’s because anyone prefer to read from this aggregator site than go to a “real” site. The aggreator used RSS tech, i should modify WordPress RSS. The aggregator site only read the title and author. How about the content? The idea is to make people go to a “real” site, that’s why i don’t need the content shows in RSS.

I choose to modify RSS2 because it is suitable with the theme.
WordPress RSS2 file located inside wp-includes folder. Duplicate feed-rss2.php to avoid any mistakes in the future, you can use the duplicate file is something goes wrong. Open feed-rss2.php with notepad or other editors.

We don’t need the content, find this line :

<guid isPermaLink="false"><?php the_guid(); ?></guid>

You’ll get the content xml code.

<?php if (get_option('rss_use_excerpt')) : ?>
<description>
<![CDATA[<?php the_excerpt_rss() ?>]]>
</description>
<?php else : ?>
<description>
<![CDATA[<?php the_excerpt_rss() ?>]]>
</description>
<?php if ( strlen( $post->post_content ) > 0 ) : ?>
<content:encoded>
<![CDATA[<?php the_content() ?>]]>
</content:encoded>
<?php else : ?>
<content:encoded>
<![CDATA[<?php the_excerpt_rss() ?>]]>
</content:encoded>
<?php endif; ?>
<?php endif; ?>
<wfw:commentRss>
<?php echo comments_rss(); ?>
</wfw:commentRss>

Delete all. Save and upload. Test the new RSS2 feed by clicking the link from theme
