More Information

• The “the_content_feed” filter is used to filter the content of the post after it is retrieved from the database and filtered by “the_content” hook and before it is sent to RSS reader (or browser).
• The filter callback function must return the content after it is finished processing, or feed readers will see a blank item and other plugins also filtering the feed content may generate errors.
