Volete visualizzare un elenco di articoli correlati sul vostro sito web WordPress e preferite usare il codice piuttosto che un plugin?
Quando i visitatori del vostro blog hanno finito di leggere un articolo di loro interesse, offrire un elenco di articoli correlati li terrà impegnati e li aiuterà a trovare nuovi contenuti da leggere.
In questo articolo vi mostreremo come visualizzare gli articoli correlati con WordPress utilizzando il codice, senza bisogno di plugin richiesti.
Perché mostrare le pagine correlate in WordPress?
Quando il vostro blog WordPress inizia a crescere, può diventare più difficile per gli utenti trovare altri articoli sullo stesso argomento.
Visualizzare un elenco di contenuti correlati alla fine di ogni articolo del blog è un ottimo modo per mantenere i visitatori sul sito web e aumentare le pagine viste. Inoltre, contribuisce a migliorare la visibilità delle pagine più importanti, visualizzando i contenuti migliori dove gli utenti possono trovarli facilmente.
Se non avete dimestichezza con il codice, allora sarà più semplice scegliere uno dei tanti plugin per i post correlati di WordPress, in grado di visualizzare gli articoli correlati senza codice.
Ma se vi siete mai chiesti se sia possibile visualizzare gli articoli correlati senza utilizzare un plugin, allora condivideremo due diversi algoritmi che potete utilizzare per generare articoli correlati con immagini in evidenza utilizzando solo il codice:
Nota: se si desidera mostrare un’immagine in evidenza per ogni articolo correlato, assicurarsi di aggiungere prima un’immagine in evidenza a tali articoli.
Metodo 1: come mostrare gli articoli correlati in WordPress in base ai tag
Un modo efficace per individuare i contenuti correlati è cercare altri articoli che condividono gli stessi tag. I tag sono spesso utilizzati per concentrarsi sui dettagli specifici contenuti in un articolo.
Tenendo conto di ciò, è possibile aggiungere alcuni tag comuni agli articoli che si desidera mettere in relazione tra loro. Potete inserirli nel box “Tag” dell’editore di WordPress.
Dopo aver aggiunto i tag ai vostri articoli, la cosa successiva da fare è aggiungere il seguente frammento di codice al template single.php del vostro tema. Se avete bisogno di aiuto per aggiungere codice al vostro sito, fate riferimento alla nostra guida su come incollare snippet dal web in WordPress.
$orig_post = $post;
global $post;
$tags = wp_get_post_tags($post->ID);
if ($tags) {
$tag_ids = array();
foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
$args=array(
'tag__in' => $tag_ids,
'post__not_in' => array($post->ID),
'posts_per_page'=>5, // Number of related posts that will be shown.
'ignore_sticky_posts'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
echo '<div id="relatedposts"><h3>Related Posts</h3><ul>';
while( $my_query->have_posts() ) {
$my_query->the_post(); ?>
<li><div class="relatedthumb"><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_post_thumbnail(); ?--></a></div>
<div class="relatedcontent">
<h3><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_title(); ?--></a></h3>
<!--?php the_time('M j, Y') ?-->
</div>
</li>
<!--?php }
echo '</ul--></ul></div>';
}
}
$post = $orig_post;
wp_reset_query();
Questo codice cerca i tag associati a una pagina ed esegue una query del database per recuperare le pagine con tag simili.
Dove posizionare il codice? Dipende dal tema, ma nella maggior parte dei casi si dovrebbe poter incollare il codice nel template single.php del tema dopo l’articolo principale e proprio sopra la sezione dei commenti.
Se si utilizza il tema Twenty Twenty-One, come nel nostro sito dimostrativo, un buon posto dove incollare il codice è il file template-parts/content/content-single.php dopo l’header e subito dopo <?php the_content();.
Questo visualizza automaticamente i contenuti correlati su qualsiasi articolo di WordPress. È necessario modificare lo stile e l’aspetto degli articoli correlati in corrispondenza del tema aggiungendo CSS personalizzati.
Suggerimento: invece di modificare i file del tema, che potrebbero danneggiare il sito web, si consiglia di utilizzare un plugin per gli snippet di codice come WPCode.
WPCode rende sicura e facile l’aggiunta di codice personalizzato in WordPress. Inoltre, è dotato di opzioni di “inserimento” che consentono di inserire ed eseguire automaticamente gli snippet in punti specifici del sito WordPress, ad esempio dopo un articolo.
Per maggiori dettagli, consultate la nostra guida su come add-on di codice personalizzato in WordPress. Potete anche consultare la nostra recensione dettagliata di WPCode per approfondire chi siamo.
Metodo 2: Come mostrare articoli correlati in WordPress per categoria
Un altro modo per visualizzare i contenuti correlati è quello di elencare gli articoli che appartengono alla stessa categoria. Il vantaggio di questo metodo è che l’elenco degli articoli correlati non sarà quasi mai vuoto.
Come per il metodo 1, è necessario aggiungere uno snippet di codice al template single.php del tema o in un plugin di snippet di codice come WPCode. Per maggiori dettagli, fare riferimento al Metodo 1 e alla nostra guida su come add-on di codice personalizzato in WordPress.
$orig_post = $post;
global $post;
$categories = get_the_category($post->ID);
if ($categories) {
$category_ids = array();
foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
$args=array(
'category__in' => $category_ids,
'post__not_in' => array($post->ID),
'posts_per_page'=> 2, // Number of related posts that will be shown.
'ignore_sticky_posts'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
echo '<div id="related_posts"><h3>Related Posts</h3><ul>';
while( $my_query->have_posts() ) {
$my_query->the_post();?>
<li><div class="relatedthumb"><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_post_thumbnail(); ?--></a></div>
<div class="relatedcontent">
<h3><a href="<?php the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><!--?php the_title(); ?--></a></h3>
<!--?php the_time('M j, Y') ?-->
</div>
</li>
<!--?php }
echo '</ul--></ul></div>';
}
}
$post = $orig_post;
wp_reset_query();
Ora vedrete un elenco di contenuti correlati in fondo a ogni articolo.
Se si desidera modificare lo stile e l’aspetto delle pagine correlate, è necessario aggiungere CSS personalizzato in corrispondenza del tema.

Is there a way to have related post based on the post title. I do not have tags and my categories really don’t do the trick since there is no distinction between them.
This would be of great help if you had a code to show related content based on the post title.

Thank you for your nice post.
Here “ignore_sticky_posts” should be used instead of “caller_get_posts”. Because “caller_get_posts” is deprecated.

Frank says
Can you direct me as to where to add what categories I would like to limit the related posts to?
WPBeginner Support says
This method limits the posts to the category the post is in. To limit the categories you would need to create an if statement to exclude certain categories.
Admin
Greg says
Is it possible where there are more than X related posts by category that are related that you can randomise say 3 posts?
WPBeginner Support says
While it is possible, it would require adding far more to this, you may want to look into a plugin for that type of customization.

I found a way to make the smaller thumbnails, but it shows them in a column and not horizontally. How can this be modified?
Luis says
The script is working well. The only problem I have is that the thumb-nails are very large. Would there be some way to make them smaller?
WPBeginner Support says
Hi Luis,
It uses the default post-thumbnail size. You can create a new thumbnail size and then use it in the code like this:

Hello,
I’m a beginner in WorldPress.
I’d like to show Related Posts.
In the main menu I have Category A, and in Category A – Subcategories A, B and C. The posts are in Category A, but they can also be present in all 3 Subcategories.
When choosing one of the Related Posts something goes wrong and the posts from the initially chosen Subcategory don’t show correct anymore.

pawan singh says
Hi Admin, Very informative article. I like your site because of simplicity and straightforwardness. All articles are to the point but when it comes to sharing the knowledge of code you become too technical. Just ignore the fact that much of the visitors are not coding expert. Wouldn’t it be much better if you just add 2or 3 more lines in your explanation to make it complete and easily understandable to all. Anyway, great article But I want to know which code or plugin is Wpbeginner using?
Ahmad says
really helpful, thanks !
Tracy says
what really sucks about your articles is you never actually say HOW to do something. It’s all well and good to tell me to put code into my single.php, but as a beginner I don’t know what that is or where to find it. You might want to think about putting this kind of critical information into your articles instead of assuming we know what it means, or that we have surfed every one of your articles to figure it out.
Victor Siyaya says
I Agree. I have no idea where to paste this code too.
Rose says
Thanks for the great post, very useful. I came across an error in the code so wanted to share in hope it may be useful for others in the future. The error was:
WP_Query was called with an argument that is deprecated since version 3.1.0! “caller_get_posts” is deprecated. Use “ignore_sticky_posts” instead.
So I simply replaced it and it worked fine. I am also using namespacing so I needed to change WP_Query to \WP_Query plus I changed the order of the below:
global $post;
$orig_post = $post;
Thanks again
Rose

Hi,
I have a ‘Related post’ option from my wordpress theme and i am already using it. I have displayed 6 posts after the content. The problem is, it only shows 3 related posts and next three can be seen when you slide it horizontally. I don’t want that option, i want the site to display all 6 posts outright. Can you tell me how to do it?
Gyuricza Laszlo says
Hello,
Your guidance was amazing but how can i exclude a specific category from the related posts in order to not display it?
Thank you, in advance!

You can try one of the related posts plugins.

Hi Tuta,
You can use #relatedposts .relatedthumb and .relatedcontent selectors in your CSS to style it.

How to Show Related Post It In two Columns Like here in WPBeginner??
Tom says
Nice solution but not definitive for my exigence. Infact the mean problem is that this code sort the related posts from the most recent in the same category or tags. The result is that when you browse inside a category/tag you’ll always display the same few last posts, limiting hardly the older posts of your site. That’s a right conclusion? Please if you tried it share your opinion!
Joy says
1. After ‘caller_get_posts’=>1 put a comma(,)
2. Hit enter button [next line]
3. Add ‘orderby’=>’rand’
You are done. Now related posts will be shown randomly. Thank you.
Zane DeVault says
This code works great. I was wondering if you could explain what this part of the code does?
$orig_post = $post;
global $post;
…
$post = $orig_post;
I think I have a grasp on what the rest is doing, but this is throwing me for a loop.
Thanks for all your great content!

Hi! Great post!
Is there a way to combine both option, in order to call related tags only in the current category ?
Bambang says
my single.php layout :
//the_content bla bla bla code here
//Copy paste Related Posts by Tags code here
//comments_template bla bla bla code here
——————————-
the result i got error :
Parse error: syntax error, unexpected ‘endwhile’ (T_ENDWHILE) in …
——————————-
after i change ” <? } " to " <?php } " it worked,
just sugestion, maybe it better if you put complete php open tag
thanks
Alex says
Works perfect. How to exclude the definite tag from Related Posts by Tags? I mean how to change the code when algorithm would find other posts with any one of the tag (except tag 595 for instance) that the current post has and will list them.
Mohammad says
Thanks for the great code
It works great but you didn’t address any css codes for a more beautiful look for this section. Can you please do this? I’m newbie to coding and I tried some codes but they didn’t work. In your codes there is:
echo ‘Related Posts’;
but in some similar codes I found in other resources there is:
and in css some codes like this:
.relatedposts {
font-size: 12px;
width: 640px;
}
.relatedposts h3 {
font-size: 20px;
margin: 0 0 5px;
}
will get that a nice look but it didn’t work with your code.
Thanks

Parse error: syntax error, unexpected end of file in C:\xampp\htdocs\beingusefull\wp-content\themes\TechPlus\single.php on line 78
WPBeginner Staff says
That will depend on your individual theme and template. You need to add the conditional tag after the WordPress loop begins. After this line:
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>Jenny says
I got that error too and this is my updated code:
ID);
if ($tags) {
$tag_ids = array();
foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
$args=array(
‘tag__in’ => $tag_ids,
‘post__not_in’ => array($post->ID),
‘posts_per_page’=>5, // Number of related posts that will be shown.
‘caller_get_posts’=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) { ?>
Related Posts
have_posts() ) : $my_query->the_post(); ?>
<a href="” rel=”bookmark” title=””>
<a href="” rel=”bookmark” title=””>

When the post i share on facebook, the thumbnail getting from related post, can i get the thumbnail from the main page? thx
Lacey Tech Solutions says
If you’re using Yoast’s WordPress SEO plugin you can specify the thumbnail URL under the social tab for the post. If the social tab isn’t shown then you need to click the Yoast SEO link in the WordPress admin menu then click “Social”. In the social page tick the option for, “Add Open Graph meta data” and save. Go back into your post and you can specify the thumbnail image you want to use when the post is shared. If you don’t implicitly set the post image the user has the option of selecting any image that appears on the page, which is why your recent post images are being pulled in when you share the article link.
Gretchen Louise says
Any thoughts on how much of a database/server load this would be on a large self-hosted site? Looking for a related posts alternative now that #nRelate is no longer available.
WPBeginner Staff says
Use conditional tag if (is_single()) on the first line of the code.

This doesn’t work in the single.php for me, b/c related posts show up at the very bottom of the page. It works with loop.php but then they also show up on the homepage – any ideas on a fix so it just shows in single posts and not the homepage?

Jonathan says
Is there a way to choose a single category (let’s call it Brands) and then have it display related posts only affiliated with the child categories under Brands? So, the hierarchy for the cats would be Brands > JCPenny. I want to only show related posts for JCPenny. But, that child category could be different per post. So if a post uses a different child category it’ll show related posts for that child cat. Can this code be modified to handle that somehow?
Jonathan says
OH! I think I’ve got it. I just added ‘parent’ => ‘the cat id number’, to the args and I think that did it.
Jonathan says
wait… no, that didn’t work
Miro says
Hi, thanks for the code, but instead of grabbing the featured image as a thumb, can i grab instead the first image in my posts? Thanks

It would be great if you guys would make a post on it. Thank you very much and will be waiting. Hope that you can kindly post here a notification once you made the post so we know.
Caleb says
Great post thanks! I run a website that uses WP more as a CMS with a large number of pages rather than posts. Can I do this with as related pages instead, so that it’s grabbing related pages and not posts? If so how do I go about doing this.
