Here is a very useful piece of code that will allow you to create a new RSS feed in WordPress.

Indeed, we sometimes need to provide an RSS feed independent of the native feed. For this, there is a piece of code that I discovered on Yoast!

1) Create a new page template called pagerss.php

Start from a blank page in Notepad and insert the following code, before uploading it to your theme folder:

Please leave this field empty

Don't miss business advice by email

E-mail address *

No spam, just an email when new content is published.

Check your inbox or spam folder to confirm your subscription.

<?php
/*
Template Name: Custom Feed
*/

$numposts = 10;

function custom_rss_date($timestamp = null) {
$timestamp = ($timestamp==null) ? time(): $timestamp;
echo date(DATE_RSS, $timestamp);
}

$posts = query_posts('showposts='.$numposts);

$lastpost = $numposts – 1;

header(“Content-Type: application/rss+xml; charset=UTF-8”);
echo ' ';
?>
<channel>

Your URL
your description
fr-fr
post_date_gmt) ); ?>
post_date_gmt) ); ?>
Your mail
<?php foreach ($posts as $post) { ?>
<item>

ID); ?>
<![CDATA[ post_content; ?>]]>
post_date_gmt) ); ?>
ID); ?>
</item>
<?php } ?>
</channel>
</rss>

You can replace the “Your…” fields with your own fields.

2) Create a new page in WordPress

Publish a new page from your WordPress admin, affiliating it with the “Custom Feed” page template that we have just created above.

3) Launch your published page

Once the page is published, launch it. You should see your new RSS feed!
