Kürzlich wurden wir gefragt, wie eine begrenzte Anzahl von Tags nach jedem Beitrag in Ihrem WordPress-Theme angezeigt werden kann. Normalerweise verwendet man eine Funktion the_tags(), um einen Link zu den Tags anzuzeigen, zu denen ein Beitrag gehört. Diese Funktion hat jedoch keinen Parameter, um die Anzahl der angezeigten Tags zu begrenzen. Wenn Ihr Beitrag also 12 Tags hat, Ihr Theme aber nur Platz für 5 bietet, sieht das im Design vielleicht nicht so gut aus. Viele Leute schränken die Verwendung von Tags einfach ein oder nehmen sie gar nicht erst in ihre Vorlagen auf. Aber in diesem Artikel zeigen wir Ihnen, wie Sie die Anzahl der Tags nach Beiträgen in Ihrem WordPress-Theme begrenzen können, ohne die Anzahl der Tags zu begrenzen, die Sie jedem Beitrag hinzufügen.
Edit: Nachdem ich diesen Artikel geschrieben hatte, antwortete mir der großartige Otto (@otto42) auf meinem Google+-Konto und teilte mir mit, dass es einen einfacheren Weg gibt, dies zu erreichen.
Zuerst müssen Sie die Datei functions.php Ihres Themes öffnen und diese Funktion hinzufügen:
add_filter('term_links-post_tag','limit_to_five_tags');
function limit_to_five_tags($terms) {
return array_slice($terms,0,5,true);
}
Sie können die Zahl 5 in die von Ihnen gewünschte Höchstzahl ändern.
Öffnen Sie dann Ihre loop.php, single.php, index.php oder wo auch immer Sie diese Post-Tags hinzufügen möchten (muss innerhalb einer Post-Loop sein), und fügen Sie den folgenden Code ein:
<?php the_tags() ?>
Das ist auf jeden Fall viel einfacher als das, was ich mir ausgedacht hatte, was ich in diesem Beitrag für diejenigen, die es interessiert, stehen lassen werde.
Alte komplizierte Methode
Sie müssen lediglich den folgenden Code in Ihre Themadatei einfügen (innerhalb der Beitragsschleife):
<?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
}
}
?>
Mit dem obigen Code werden 6 Tags im Theme angezeigt. Wenn Sie weniger oder mehr Tags anzeigen möchten, passen Sie einfach die Zeile $count > 5 mit der gewünschten Zahl an. Denken Sie daran, dass wir 6 Tags sehen, obwohl die Zahl größer als 5 ist. Das liegt daran, dass die Zählung bei 0 beginnt. Wenn Sie also nur 4 Tags anzeigen möchten, müsste die Zahl 3 sein.
Wenn Sie das Trennzeichen ändern wollen, müssen Sie Zeile 9 ändern. Der aktuelle Code trennt durch Kommas. Sie können auch das Styling anpassen, indem Sie Divs, Listenelemente oder etwas anderes hinzufügen.

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
