Recentemente ci è stato chiesto come visualizzare un numero limitato di tagga dopo ogni articolo nel tema di WordPress. Normalmente, si utilizza la funzione the_tags() per visualizzare un collega ai tag a cui appartiene un articolo. Tuttavia, questa funzione non ha un parametro per limitare il numero di tag visualizzati. Quindi, se il vostro articolo ha 12 tag e il tema ha spazio solo per 5, il design potrebbe non avere un bell’aspetto. Molti limitano l’uso dei tagga o non lo includono nemmeno nei template. In questo articolo vi mostreremo come limitare il numero di tag dopo i temi di WordPress senza limitare il numero di tag aggiunti a ciascun articolo.
Modifica: A quanto pare, dopo aver scritto questo articolo, il fantastico Otto (@otto42) mi ha risposto sul mio account di Google+ per farmi sapere che esiste un modo più semplice per ottenere questo risultato.
Per prima cosa è necessario aprire il file functions.php del tema e aggiungere questa funzione:
add_filter('term_links-post_tag','limit_to_five_tags');
function limit_to_five_tags($terms) {
return array_slice($terms,0,5,true);
}
È possibile cambiare il numero 5 con il numero massimo che si desidera.
Poi aprite il vostro loop.php, single.php, index.php, o dovunque vogliate aggiungere questi tagga (deve essere all’interno di un loop di post), quindi incollate il seguente codice:
<?php the_tags() ?>
Questo è sicuramente molto più semplice di quello che avevo escogitato io, che lascerò in questo articolo per coloro che sono interessati.
Vecchio metodo complicato
È sufficiente incollare il seguente codice nel file del tema (all’interno del loop dell’articolo):
<?php
$posttags = get_the_tags();
$count=0; $sep='';
if ($posttags) {
echo 'Tags: ';
foreach($posttags as $tag) {
$count++;
echo $sep . '<a href="'.get_tag_link($tag->term_id).'">'.$tag->name.'</a>';
$sep = ', ';
if( $count > 5 ) break; //change the number to adjust the count
}
}
?>
Il codice qui sopra visualizza 6 tag nel tema. Se si desidera mostrare meno tag o più tag, è sufficiente regolare la riga $count > 5 con il numero desiderato. Ricordate che, anche se il numero del conteggio è maggiore di 5, noi vediamo 6 tag. Questo perché il conteggio parte da 0. Quindi, se si desidera mostrare solo 4 tagga, il numero deve essere 3.
Se si desidera cambiare il separatore, è necessario modificare la riga 9. Il codice attuale separa con le virgole. È inoltre possibile personalizzare lo stile aggiungendo div, elementi di elenco o qualsiasi altra cosa si desideri.

This code snippet works great.
But I need one modification: I need to only show the first three tags that I enter for each blog post. It’s now showing three tags, which is a good step.
However, I specifically need the first three in the order I specify. This is because of the purpose my website serves and how research data is presented. For example:
Jennifer Weaver, Case #4455883, New Mexico
That’s how I’m entering tags: Name, case number, location — and then I have some additional tags. But I only want the first three to display in the entry meta.
Any suggestions how to do this? The code you shared chooses any order it wants. If my tags are entered like this — one, two, three, four, five — it chooses its own arrangement, such as:
five, four, one
Thanks for any help you can offer with this!!

Hello!
How can I do this “limit the usage of tags”. I want only 3 tags per post/product. And if I select a 4, the number is erased.
Thank you!
WPBeginner Support says
@Hector Thanks for the suggestion. We have published a new article on how to set maximum tags for WordPress posts. Please take a look, let us know if it helps.

Hi, how can i add if is statement to this function?
I want to show 5 tags on my main Blog Page(Static page with id=99),
and then show all tags in single-post page
Is it possible to combine this function, to work with post category?
Like Above, i want 5 categories and 5 tags on main page, and full list on single-post…
Sorry for my English ;/
WPBeginner Support says
For that you will have to edit your theme or child theme’s template file. For tags you can try this code:
<?php $posttags = get_the_tags(); $count=0; if ($posttags) { $output = ''; foreach($posttags as $tag) { $count++; $output .= $tag->name . ' '; if( $count >5 ) break; } } echo $output; ?>1-click Use in WordPress

Great info. I came to this site though google search looking for an answer to another problem I need the tag pages to display their tag names as a heading for their individual tag pages. Is there any theme that does this? I am currently using the Divi theme and that feature is not available.

You probably didn’t paste it in the right syntax.

What about duplicate content (after Panda update) using tags as same article will be on the post and tag pages.
Also, i read on wp forum regarding the negative impact of using excessive tags (more than 10 tags) for each post.
wpbeginner says
@ata People should not use Tags for SEO. Tags are built-in to WordPress to improve the usability of your site. You can have 500 tags for one post for all that matters. What is crucial is that you follow, noindex the tags pages. So search engines go to those pages and follow all the links, but don’t index those pages. That will solve the SEO problem. There are too many self-proclaimed SEO experts who don’t know what the heck they are doing. Putting generic statements like the ones you mentioned above are totally wrong as long as you follow what we are saying.
ata says
Actually tags does increase traffic for some sites. You can find proof on Google. Especially long tail keywords attached to a post.
Not sure how the search engine can find your tag links if it is set as ‘noindex’. Maybe the post url but not the tag links as it doesn’t make sense.
The ‘generic statement’ was not a statement.at all. If you read my comment, it is more of a query/question so there is no need to bite my head off.
wpbeginner says
@ata First of all let me be clear. I am not biting your head off. The frustration was expressed toward those experts that go along making generic claims like that. WordPress allows for many ways of indexation. Most folks use category as their primary method of archives. In order to prevent duplicate content, you can only use ONE primary method of archive that is indexable. All secondary methods need to be no-index in order to prevent duplicate content.
We use Categories as our main method of archiving. If you want you can use tags as a primary source of archiving. We find that categories tend to perform better for our blogs. If you want to use tags as a primary source of archiving, then no-index categories, and date based archives. If you are the only author on the site, then you might as well no-index author archives because that will just produce duplicate content as well.Will not argue SEO theories any further in this article because this is a tutorial for design not SEO.

I was looking for this. Thanks for sharing. I agree with @mrahmadawais the first method works just fine and it is simple too.

the first method is just great
