Volete creare un feed RSS personalizzato in WordPress?
WordPress è dotato di un feed RSS predefinito che mostra i contenuti del sito web. Tuttavia, se avete un tipo specifico di contenuti, potreste voler creare un feed RSS personalizzato.
In questo articolo vi mostreremo come creare facilmente un feed RSS personalizzato in WordPress.
Perché creare un feed RSS personalizzato in WordPress?
WordPress è dotato di un feed RSS integrato, al quale è possibile aggiungere facilmente contenuti personalizzati o miniature.
Tuttavia, se avete un tipo specifico di contenuto o un post type personalizzato sul vostro sito web WordPress, potreste voler creare un feed RSS personalizzato per esso.
Ad esempio, se fornite ai vostri abbonati contenuti esclusivi di autori specifici, potete creare un feed RSS personalizzato per tenere informati i vostri abbonati sui contenuti. Questo può migliorare il posizionamento sui motori di ricerca.
Inoltre, i feed personalizzati consentono una maggiore libertà, abilitando l’aggiunta del nome dell’autore, delle date di pubblicazione o di qualsiasi altra informazione rilevante, fornendo maggiori dettagli agli utenti.
Detto questo, vediamo come creare facilmente feed RSS personalizzati in WordPress, passo dopo passo.
Nota: è consigliabile creare un backup completo del sito web WordPress prima di apportare modifiche importanti a un sito web attivo.
Come creare un feed RSS personalizzato in WordPress
È possibile creare facilmente un feed RSS personalizzato in WordPress aggiungendo del codice personalizzato al file functions.php del tema .
Questo feed visualizza il titolo, il collega, la data di pubblicazione, l’autore e i riassunti degli articoli sul vostro sito WordPress.
Tuttavia, tenete presente che il più piccolo errore durante la digitazione di questo codice può rompere il vostro sito web e renderlo inaccessibile.
Ecco perché vi consigliamo di utilizzare WPCode. È il miglior plugin per gli snippet di codice di WordPress presente sul mercato che rende sicuro e facile aggiungere codice personalizzato al vostro sito web.
Per prima cosa, è necessario installare e attivare il plugin WPCode. Per istruzioni dettagliate, consultare la nostra guida per principianti su come installare un plugin di WordPress.
Nota: per questa esercitazione è possibile utilizzare il plugin gratuito WPCode. Tuttavia, l’aggiornamento al piano a pagamento sblocca altre caratteristiche come la modalità di test, la libreria cloud, la logica condizionale e altro ancora.
Dopo l’attivazione, visitare la pagina Code Snippets ” + Add Snippet dalla barra laterale dell’amministrazione di WordPress. Qui, fare clic sul pulsante “Usa snippet” sotto l’opzione “Aggiungi codice personalizzato (nuovo snippet)”,
Si accede così alla pagina “Crea snippet personalizzato”, dove si può iniziare a digitare un nome per lo snippet di codice.
Quindi, scegliere l’opzione “Snippet PHP” dal menu a discesa Tipo di codice sulla destra.
Una volta fatto ciò, aggiungere il seguente codice personalizzato nella casella “Anteprima codice”:
add_action('init', 'customRSS');
function customRSS(){
add_feed('Feed', 'customRSSFunc');
}function customRSSFunc(){
get_template_part('rss', 'feedname');
}<?php
/**
* Template Name: Custom RSS Template - Feedname
*/
$postCount = 5; // The number of posts to show in the feed
$posts = query_posts('showposts=' . $postCount);
header('Content-Type: '.feed_content_type('rss-http').'; charset='.get_option('blog_charset'), true);
echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>';
?>
<rss version="2.0"
xmlns:content="http://purl.org/rss/1.0/modules/content/"
xmlns:wfw="http://wellformedweb.org/CommentAPI/"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:atom="http://www.w3.org/2005/Atom"
xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"
xmlns:slash="http://purl.org/rss/1.0/modules/slash/"
<?php do_action('rss2_ns'); ?>>
<channel>
<title><?php bloginfo_rss('name'); ?> - Feed</title>
<atom:link href="<?php self_link(); ?>" rel="self" type="application/rss+xml" />
<link><?php bloginfo_rss('url') ?></link>
<description><?php bloginfo_rss('description') ?></description>
<lastBuildDate><?php echo mysql2date('D, d M Y H:i:s +0000', get_lastpostmodified('GMT'), false); ?></lastBuildDate>
<language><?php echo get_option('rss_language'); ?></language>
<sy:updatePeriod><?php echo apply_filters( 'rss_update_period', 'hourly' ); ?></sy:updatePeriod>
<sy:updateFrequency><?php echo apply_filters( 'rss_update_frequency', '1' ); ?></sy:updateFrequency>
<?php do_action('rss2_head'); ?>
<?php while(have_posts()) : the_post(); ?>
<item>
<title><?php the_title_rss(); ?></title>
<link><?php the_permalink_rss(); ?></link>
<pubDate><?php echo mysql2date('D, d M Y H:i:s +0000', get_post_time('Y-m-d H:i:s', true), false); ?></pubDate>
<dc:creator><?php the_author(); ?></dc:creator>
<guid isPermaLink="false"><?php the_guid(); ?></guid>
<description><![CDATA[<?php the_excerpt_rss() ?>]]></description>
<content:encoded><![CDATA[<?php the_excerpt_rss() ?>]]></content:encoded>
<?php rss_enclosure(); ?>
<?php do_action('rss2_item'); ?>
</item>
<?php endwhile; ?>
</channel>
</rss>
Ora è possibile cambiare il nome del feed RSS personalizzato con quello che si desidera, sostituendo il testo Feed dopo la riga add_feed del codice.
Una volta creato il feed, sarà possibile visualizzarlo andando all’URL del feed RSS. L’aspetto sarà il seguente: yourdomain.com/feed/feedname.
Scorrete poi verso il basso fino alla sezione di inserimento e scegliete la modalità “Inserimento automatico”.
Il feed RSS personalizzato verrà creato automaticamente all’attivazione del codice.
Infine, tornate in alto e spostate l’interruttore “Inattivo” su “Attivo”.
Quindi, fare clic sul pulsante “Salva snippet” per salvare le impostazioni.
Una volta fatto ciò, visitate la pagina Impostazioni ” Permalinks dalla dashboard di WordPress.
Qui è sufficiente fare clic sul pulsante “Salva modifiche” per cancellare le regole di riscrittura e generare nuovi permalink per il sito web.
Ora è possibile visualizzare il feed RSS personalizzato visitando l’URL yourdomain.com/feed/feedname.
Ecco un esempio di feed RSS personalizzato sul nostro sito web WordPress demo:
Bonus: Risoluzione dei problemi dei feed RSS personalizzati
Ecco un elenco di alcuni errori che possono verificarsi quando si cerca di creare un feed RSS personalizzato e come è possibile risolverli.
Ricevo un errore 404 quando cerco di visualizzare il mio feed!
Se si ottiene l’errore 404 quando si cerca di visualizzare il feed personalizzato, verificare se si sta utilizzando il nome corretto del feed nell’URL.
Deve essere quello fornito nella funzione add_feed. Se il nome del feed è corretto, è possibile che le regole di riscrittura non siano state cancellate correttamente. Si può facilmente rimediare salvando i permalink.
Se avete salvato i permalink e il problema persiste, potete forzare una riscrittura aggiungendo questo codice nel vostro snippet WPCode accanto alla funzione add_ feed:
global $wp_rewrite;
$wp_rewrite->flush_rules();
Il mio feed non è valido!
Il W3C offre un servizio di convalida dei feed che consente di convalidare il feed risultante e fornisce dettagli specifici sui punti in cui il feed non è valido.
È quindi possibile modificare facilmente lo snippet di codice per correggere questi problemi.
Ricevo un errore di validazione <language />!
Questo accade spesso quando la lingua RSS non è stata configurata sull’installazione di WordPress.
A tale scopo, è possibile aggiungere il seguente codice a WPCode per aggiornare l’opzione della lingua:
function rssLanguage(){
update_option('rss_language', 'en');
}
add_action('admin_init', 'rssLanguage');
Una volta fatto ciò, modificare il secondo argomento della funzione update_option per cambiare la lingua con quella desiderata. Si veda l’elenco completo dei codici di lingua RSS.
Una volta salvato lo snippet, l’errore verrà rimosso e si potrà visualizzare il feed RSS personalizzato.

Jonathan says
Following this tutorial, for some reason changing the $postCount does not work.
Eg,
$postCount = 20; // The number of posts to show in the feed
Only by changing the default number inside of WordPress Reading settings does it work. Very weird. How do we overwrite the wordpress settings, or stop the wordpress settings from overriding our code?
WPBeginner Support says
Your specific theme may be overriding the number of posts to show, we would first recommend checking with the support for your specific theme and they should be able to assist.

Hi.
How i can add custom post types and custom fields in feed?
WPBeginner Support says
You would want to take a look at two of our other articles below for that information.

Dexter Nelson says
Is there any way to make this permanent? I keep having to repeat this step every few weeks when the theme is updated.
WPBeginner Support says
For that, you would want to create a child theme following our guide below:
https://www.wpbeginner.com/wp-themes/how-to-create-a-wordpress-child-theme-video/
Admin
Dexter Nelson says
Thanks. But doesn’t that mean when the theme is updated I’ll have to update the child theme? If that’s the case and I have to put in the work either way, I might as well put in the work to create and maintain a plugin and help out others instead of just myself, right?
WPBeginner Support says
Child themes should not be affected by updates to the parent theme but if you have the ability to create a plugin then you can certainly go down that path to help others as well.
Thommy Kusbin says
is there any plugin to do this kind of custom rss feed XML? I want to use my own tag xml.
WPBeginner Support says
We do not have a recommended plugin at this time, we will be sure to keep an eye out.

John Snyder says
I need to create an XML feed for a specific page on my WordPress website. Here is the page will I have to edit my functions.php file or is there an easier way?
Alok Shrestha says
Hello,
This article is very helpful but I got some issue.
I did exactly like in your code. But it gives me an error as
This page contains the following errors:
error on line 1 at column 7: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error.
Could you please help me out what could possibly go wrong here?
This is very important for me.
Thank you.
Nathan says
I got the same error. Did you figure out the fix?
Rich says
Use ob_clean(); after php tag
Guillermo says
Hi, is it possible to change de order of the posts in my feeds without creating a new custom feed? I want to use the current feed files but just want to change the displayed order of theme. Using PHP queries as an example, changing order from DESC to RAND()
I will appreciate you help. Thanks.
Jeremy says
Great post! I definitely fall under the rookie status. Many feed readers/aggregators don’t seems to like the /feed/ URL structure, even through the xml returned validates. Is there a way to append the url to end with rss.xml?
Dave says
Did you get this to work with .xml at the end?
JDURAN says
Sorry to say, however, implementing the codes for custom rss has effectively wiped out my entire blog. Having to do a restore and it is taking a long time to get my blog back up. Any advise?
Mark says
You need to connect to your site via FTP or your hosting’s file browser in cPanel, and simply remove what you added. If you added the code as a custom plugin, then just rename the plugin folder. If you added the code in functions.php, edit the file and remove the code. Don’t forget to backup the file before editing. Hope this helps for the next time.
jim says
Fantastic! This works as advertised!
DrLightman says
Never mind, it does. I had a bug with YOAST SEO that with the /category/ prefix removal. I have warned them of it I hope they will fix it.
DrLightman says
Hello, thank you for the article, but it seems this will only work for the main site feed, not for the specific catgories feeds:
mysite.com/category/mycat/feed/feedname/
Manuel says
Doesn’t work anymore.
I got a 404 error, so I activated debug mode. Debug mode says “Notice: The Called Constructor Method For WP_Widget Is Deprecated Since Version 4.3.0! Use __construct()”
Manuel says
Ok, I think the problem was elsewhere and this notice is from a different plugin.
git says
unfortunately this is restricted in its usefulness. inserting screenshots and sample pages would be very helpful, particularly for amateurs/rookies like me.
Tiffany says
Great article. Any way to add the featured image for the post to the feed?
WPBeginner Support says
Please see our guide on how to add featured image to your WordPress RSS feed.

Please see below screenshots – what determines the “…” or “[…]” or “Read More ->” etc etc in feeds?

Apologizes but that code did not come through clear lol. Lets try that again. Go here to see the exact, raw code I’m looking to remove:

This code is added by Yoast SEO plugin to RSS feeds. You can turn it off by visting SEO » Advanced page.

How do you add multiple feeds? Array is not working. Thanks.
Jon Harvey says
How would you add multiple custom feeds? Couldn’t get an array to work.
Thanks
Jon Harvey says
Got it to work neatly thanks to birgire at Stack exchange:
add_action( ‘init’, ‘custom_feeds’ );
function custom_feeds()
{
foreach( array( ‘feedname1’, ‘feedname2’ ) as $name )
{
add_feed( $name,
function() use ( $name )
{
get_template_part( ‘rss’, $name );
}
);
}
}

Sorry, but everything about this is misleading. this is not “beginner” work. and it is not worded for beginners. This is totally irresponsible and can cause major issues to people’s websites.

I got this working (kind of). The feed page exists, but will not validate and says there is an error on line 1.
I copied the code exactly from this page and haven’t changed anything. What could be going wrong here?

W3 will not validate mine as well and says there is an error on line 17.

Hi.
I would like to change the update pattern of the feed with
sy:updatePeriod
echo apply_filters( ‘rss_update_period’, ‘weekly’ );
/sy:updatePeriod
sy:updateFrequency
echo apply_filters( ‘rss_update_frequency’, ‘1’ );
/sy:updateFrequency>
sy:updateBase
2015-03-29T01:00:00+09:00
/sy:updateBase
But whatever I tried, it automatically adds a new post when I publish it and does not wait till Sunday ( as defined in the code above) to add it to the RSS.
Do you have any suggestions? Do I maybe need to find a solution within the WP Query?
Your help would be much appriciated.

Hi,
My feed is OK when this code is added:
global $wp_rewrite;
$wp_rewrite->flush_rules();
and returns a 404 when it is removed.
I only remove it as per your instructions, which is to remove it after reloading wordpress.
At this moment I am testing it on my local server. Could this be why?

Hi there. Thanks for this post! Really appreciated. Worked well at first go!
I would also like some assistance as Brian below. For the full text in the RSS instead of the post excerpt.
Thanks in advance.
Brian says
I am trying to add a second RSS feed that is full text (my first RSS feed is summary). If I wanted this custom RSS feed to be full text instead of summary excerpt, what would I change?
Thanks so much!
Steve Marks says
Thanks for this. Just what I was looking for!
I had an issue when I used add_feed(). I could view the RSS feed in the browser absolutely fine, but it would return a 404 when I entered the URL into a third party application (ie. MailChimp, W3C feed validator etc). I had tried flushing the permalinks etc.
The only way I could get round the issue was to create a new blank page and select the template as the one you’ve outlined in this article.
Not sure why it didn’t work, but hopefully this offers a viable solution for others in this situation.
Thanks again!
Josh McClanahan says
Your article is right on the path of what I was looking for. One question I have (as a noob to RSS), how can I add a link to an RSS feed?
The site that I need this for is a church and would like to have a custom feed that would make it easier for our members to be alerted to newly posted sermon posts (that have mp3 download links).
Currently, the feed shows the text for the links that I have created on the posts for the sermons. But it only acts as text. Any help would be appreciated.
Josh McClanahan says
Just noticed that I didn’t ask my question correctly.
What I was trying to ask was, how can I display a link in the RSS Feed? The links that are in the content of my posts are broken in the feed.
Thanks for your help and this article.
Josh McClanahan says
Still curious, if anyone knows why my links would be broken and only show as plain text in a feed?
To see what I mean checkout: http://amfmchurch.com/feed
You will see “Download” in plain text. I would like to make it so that people can click the anchor link and download the mp3. This works find on the actual site.
Thanks for any help.
Neil says
Hi, I have the default rss feed.. but I would like to be able to either reduce the size of the images from what is displayed in the post…. (to a maximujm width of 265px) OR to just use the post thumbnail in the rss.
Is either of the above possible?
The reason I am looking to do this is that my RSS feeds an APP and the APP will only display images up to 265px in width (before horizontal scrolling) and 265px is very limiting for online/pc blog posts…
Cathy Finn-Derecki says
Thank you for this! I am making a custom RSS location part of a plugin I’m developing. As a result, I have included the text for the custom RSS in the function, not in a theme template. It’s working. However, it does not seem to work when I want to restrict the feed to a category. It gives all posts regardless. Any thoughts?
WPBeginner Support says
try changing
$posts = query_posts('showposts=' . $postCount);1-click Use in WordPress
To:
$posts = query_posts('showposts=' . $postCount.'&category_name=staff');1-click Use in WordPress
Replace category_name with your category name.

the Off says
Hello,
Till yesterday afternoon, my WordPress (version 3.6.1) blog http://theoff.info/wordpress/ had no problem. And I successfully added new plugins.
In the night, problems started: (1) I could not login. (2) the RSS feed http://theoff.info/wordpress/?feed=rss2 got corrupted. The feed failed validation.
I searched the Web and WordPress Support Forum for solutions. I tried the following:
(i) successfully reset the password
(ii) deleted new plugins from ftp
(iii) renamed Theme folder by adding “-old” and plugin folder by adding “-hold” from ftp
Then I could login and up grade to 3.7.1 version and make changes to the blog.
However, login is still an issue. Every time I am following method mentioned in step (iii) to login.
RSS still does not validate.
Could you help in resolving both login and RSS feed problems?
Note: My webhost does not offer technical help. I am not an IT professional i.e. I have very little technical knowledge.
Thanks
WPBeginner Support says
It is difficult to figure out. Here is one thing you can try.
1. Using FTP download your plugins to your computer for backup and then delete your plugins directory.
2. Create a new plugins directory.
3. Install and all your plugins one by one by downloading fresh copy of the plugin from the source. After you activate each plugin log out and and log back in to see if the problem occurs again. You will probably find a plugin that may be causing the problem or you wont. This could mean that a plugin file on your site may have been compromised.
If this process does not help you, repeat this process process with your themes as well. If you have made a lot of changes to your existing themes then you might want to back it up on your computer by downloading theme folder through FTP. Then delete themes folder from your webserver and create a new themes directory in wp-content folder on your server. From WordPress admin area download and install a fresh copy of default twenty thirteen theme.
Let us know what happens when you do all that. Make Sure to Backup your Site first.
