Czy chcesz wyświetlić listę powiązanych wpisów na twojej witrynie internetowej WordPress i wolisz używać kodu zamiast wtyczki?
Gdy odwiedzający twojego bloga skończą czytać interesujący ich artykuł, zaoferowanie listy powiązanych wpisów utrzyma ich zaangażowanie i pomoże im znaleźć nowe treści do przeczytania.
W tym artykule pokażemy, jak wyświetlić powiązane wpisy w WordPressie za pomocą kodu, bez konieczności korzystania z wtyczki.
Dlaczego warto wyświetlać wpisy powiązane w WordPress?
Kiedy twój blog WordPress zaczyna się rozrastać, użytkownikom może być trudniej znaleźć inne wpisy na ten sam temat.
Wyświetlanie listy powiązanych treści na końcu każdego wpisu na blogu to świetny sposób na zatrzymanie odwiedzających na twojej witrynie internetowej i zwiększenie liczby odsłon. Pomaga również poprawić widoczność twoich najważniejszych stron, wyświetlając najlepsze treści tam, gdzie ludzie mogą je łatwo znaleźć.
Jeśli nie jesteś obeznany z kodem, to łatwiej będzie ci wybrać jedną z wielu wtyczek WordPress do wyświetlania wpisów powiązanych bez kodu.
Ale jeśli kiedykolwiek zastanawiałeś się, czy możesz wyświetlać powiązane wpisy bez użycia wtyczki, podzielimy się dwoma różnymi algorytmami, których możesz użyć do generowania powiązanych wpisów z miniaturami za pomocą samego kodu:
Uwaga: Jeśli chcesz wyświetlać miniaturkę przy każdym powiązanym wpisie, upewnij się, że najpierw dodałeś obrazek wyróżniający do tych wpisów.
Metoda 1: Jak wyświetlić powiązane wpisy w WordPressie za pomocą tagów?
Jednym ze skutecznych sposobów na zlokalizowanie powiązanych treści jest wyszukiwanie wpisów, które mają te same tagi. Tagi są często używane do skupienia się na konkretnych szczegółach zawartych we wpisie.
Mając to na uwadze, możesz dodać kilka wspólnych tagów do wpisów, które chcesz ze sobą powiązać. Możesz je wpisz w polu „Tagi” w edytorze WordPress.
Po dodaniu tagów do twoich wpisów, następną rzeczą do zrobienia jest dodanie następującego fragmentu kodu do szablonu single.php twojego motywu.
Jeśli potrzebujesz pomocy w dodaniu kodu do twojej witryny, zapoznaj się z naszym przewodnikiem na temat wklejania fragmentów kodu z sieci do WordPressa.
$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();
Ten kod szuka tagów powiązanych ze stroną, a następnie uruchamia zapytanie do bazy danych w celu pobrania stron z podobnymi tagami.
Gdzie należy umieścić kod? To zależy od twojego motywu, ale w większości przypadków powinieneś być w stanie wkleić kod do szablonu single.php twojego motywu po głównym wpisie i tuż nad sekcją komentarzy.
Jeśli korzystasz z motywu Twenty Twenty-One, tak jak my na naszej witrynie demonstracyjnej, dobrym miejscem do wklejenia kodu jest plik template-parts/content/content-single.php po nagłówku i zaraz po <?php the_content();.
Spowoduje to automatyczne wyświetlanie powiązanych treści w dowolnym wpisie WordPress. Będziesz musiał zmienić styl i wygląd powiązanych wpisów, aby dopasować je do twojego motywu, dodając własny CSS.
Wskazówka: Zamiast edytować pliki motywu, co może zepsuć twoją witrynę internetową, zalecamy użycie wtyczki fragmentów kodu, takiej jak WPCode.
WPCode umożliwia bezpieczne i łatwe dodawanie własnego kodu w WordPress. Ponadto zawiera opcje „Insertion”, które pozwalają automatycznie wstawić i wykonać fragmenty kodu w określonych miejscach na twojej witrynie WordPress, na przykład po wpisie.
Aby uzyskać więcej informacji, zapoznaj się z naszym przewodnikiem na temat dodawania własnego kodu w WordPress. Możesz również sprawdzić naszą szczegółową recenzję WPCode, aby dowiedzieć się więcej o wtyczce.
Metoda 2: Jak wyświetlić powiązane wpisy w WordPressie według kategorii?
Innym sposobem wyświetlania powiązanych treści jest lista wpisów, które znajdują się w tej samej kategorii. Zaletą tej metody jest to, że lista powiązanych wpisów prawie nigdy nie będzie pusta.
Podobnie jak w metodzie 1, musisz dodać fragment kodu do szablonu single. php twojego motywu lub we wtyczce fragmentów kodu, takiej jak WPCode. Aby uzyskać więcej informacji, zapoznaj się z Metodą 1 i naszym przewodnikiem na temat dodawania własnego kodu w 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();
Teraz zobaczysz listę powiązanych treści na dole każdego wpisu.
Jeśli chcesz zmienić styl i wygląd powiązanych stron, będziesz musiał dodać własny CSS, aby dopasować go do twojego motywu.

It is good to show related post in wordpress blog without plugiN. iIt will consume less bandwidth and time to load. http://shareitto.com Thanks for your suggestion.
zioneyemedia
I do have a question on this: I’m wrestling on the code to capture posts from child categories versus parent categories. Any advice?
AmandaLong
This rocks … Thanks!
dustinporchia
I’m trying to use the related posts by category and I noticed that you said the code has to come before the comments in the main loop. In my code I want the related posts to come after the comments in the loop. When I do this I notice my disqus comment plugin takes longer to load now. Is that because of an error with the comments or is that normal?
dustinporchia
Nevermind…I just switched to livefyre as this is more of what I’m looking for in a comment system anyways…thanks!
subzerokh
please
could someone help a newbie like me customize this script so it’ll display related post in an horizontal way?
from left to right..
instead of currently showing it from up to down, vertically…
zioneyemedia
Hey,
How I did it is I replaced the and codes with my own html and css. The codes create lists for each post, and that is usually in a vertical fashion.
——————
<a href="” rel=”bookmark” title=””> <a href="” rel=”bookmark” title=””>
——————
I replaced the opening with and replaced the closing with as my html tags. Then I write my CSS to fit that specific div class needs on your website. For example, a sample pleft class could look like this:
.pleft {float:left; padding:2px; margin:10px; width:278px; height:190px;}
I use the float: selector on my CSS to move posts horizontally, and the margins and padding to give each post spacing within each other. I added in a specific width and height for additional examples.
Hope this helps.
Simos
@zioneyemedia thank you!
gcog
I’ve got related tags for sure, but when I add the code I see nothing. Also, when I add your code to restrict to a custom post type, it gives me an error. I did change the post type to my specific post type.
subzerokh
@wpbeginner hello
thanks for your quick answer…
but i’m a real novice at all you are saying..
can you please give a litlle exemple?
for making them horizontal as on your own blog?
can get in touch by my mail: khiloc at gmail dot com
wpbeginner
@subzerokh You would have to edit the styling. It is not that hard. Simply wrap each post in a div. Specify a width for that div and then set a float left property. Adjust the margins and such and you have it.
subzerokh
hello all!! thanks for this wonderfull script!!
It’s the only thing i found doing exactly what i wanted!!!
But it’s just showing related post in vertical way (from up to down)
I would like it to be shown from left to right (horizontally)
How to do that please??

Can I have a CSS For this please
Editorial Staff
The CSS we used was for a client’s site. You can add your own CSS on how you want to display this.
Administrator
titusmagnet
Thanks..im searching for this kinda Code
jaffa
This is great, just what I have been looking for. I wonder though, how could I combine the two above and if there are no tags then it displays posts from the same category?
Trying to figure this out but not getting very far yet
nikbanks
Thanks for the code it worked but how do I style it. I’d like it to be 4 stories side by side like yours. It is listed one on top of another on my site and not listed like yours.
Editorial Staff
That is CSS. We are not using this code to show related stories. Second, i believe what you are talking about is featured stories on our sidebar. We have written another post about that in our site.
Administrator
Coolguy
is ther a way to dispay the thumbs in related post without using featured images or post thumbs??
i.e to use any image used in the post …
Editorial Staff
Yes, you can utilize the fallback techniques shared by other developers which pulls the first image from the post. But we recommend using the WordPress post thumbnails…
Administrator
Hetal
Thanks for this article. I was wondering if there is a way to auto-tag posts without having to manually enter them.
Editorial Staff
No you have to tag each post manually.
Administrator

Great!
What if I want to display related posts by category without thumbnails?
Thanks
Editorial Staff
Just remove the thumbnail code from the code above

Thank you for posting this tutorial, it helps me a lot.

Hi there…Just wanted to say that I’ve been building my wordpress website from the ground up and this code works perfectly for me using WP 3.1….All I need to do now is style the CSS and get some thumbnails happening for the posts. Thanks for your help with the code.

thanks, i’m looking this hack for so long and you got it to me!
Patricia
Hi, is there a way to exclude categories? I have two main categories where all the categories get assigned to. The main categories have sub-categories and I would like to show just related posts from the sub-categories.
Is this possible, by excluding the id’s of the main categories?
Thanks for your advice!
BTW…love the code…and it works great!!!
Editorial Staff
You should be able to use category not in <<
Administrator

I was searching for related post with thumbnails plugins but the code that you paste above, solve my problem.
John
Just one question, is there a way to only pull tags from the same post type? Maybe using something like 'post_type=videos’?
John
By the way, got this figured out as well:
Just add it to the array:
$args=array(
'category__in’ => $category_ids,
'post__not_in’ => array($post->ID),
'posts_per_page’=> 2, // Number of related posts that will be shown.
'caller_get_posts’=>1,
'post_type’=>’videos’
);
marion
Hi,
Thank you for this tutorial. I’m wondering though if there’s anyway the related products can be randomized? I’ve checked different products in the same category and the same related products were shown.
Thanks
Editorial Staff
Yes use the Query_Post parameter for order and you can randomize it.
Administrator
Clarence Johnson
Good to know.
phdean
Hi,
I too would like to randomize the posts that display for the categories as, otherwise, they’ll display the same 2 every time. Can you please give me the code to do this?
Many thanks in advance
John
Nevermind, I got it figured out. Thanks for the post!
Editorial Staff
what was the issue?
Administrator
John
I didn’t have any other posts with the same tags, i.e. no related posts. Dummy mistake.
John
I copied this code and put it in my single.php without changing a thing and nothing gets outputted. Anything wrong with my code? pastebin.com/kg0SkrAg
James
This doesn’t bring up a thumbnail — there isn’t even a call for an image int eh code. I don’t see how anyone can get this to work.
Editorial Staff
The code for the image is: the_post_thumbnail(); << This is not static html where you will see img src code. The function calls in the database to search for a featured image aka thumbnail that is attached to each article. If found, it will output the image. Now if you do not have post thumbnails enabled in your theme, then you need to add it first:
https://www.wpbeginner.com/wp-themes/how-to-add-post-thumbnails-in-wordpress/
The article clearly stated that in the Note: section. You should consider reading it thoroughly.

hey man, I love your blog!
I have a question?
Can you do the same trick but ” BY Author” ?
showing the latest posts by author?
you will save my life
Btw thanks for this website!
Editorial Staff
Yes we will que the article soon
Administrator
Roberto Silva
yessss, thanks…
It will be a great article.
bacause „latest posts by author without plugin” is hard to find on internet.
you are the best.
Quinn
Thanks for this code! I’ve given it a try and it works somewhat.
I can get it to give a listing of the related articles, a huge benefit.
But I can’t seem to get any images to show up.
The articles have images if this code scrapes.
I also went in and created images for each post with the custom tag „relatedthumb”. But alas, still no images.
Is there something else I need to do?
Many thanks in advance!
Quinn
Editorial Staff
This trick is using the default WordPress thumbnails which was added in WP 2.9. If you have an image attached as that thumbnail, then it will pull it.
Administrator
Anthony
Is it possible to exclude a category from this module ?
Thanks a lot,
Anthony
Editorial Staff
It will only shows post on the category that the other post resides in…

I’m trying to modify his code in order to use it with categories within a custom post type. Can anyone help? I’m fairly new to php.
Thanks!
rulethenation
ok i got it to work, is there anyway to put a default pic if a thumbnail is unavailable
Editorial Staff
Yes, you can use the if paramter to check if there are plugins… if not then you can display a default image.
Administrator
rulethenation
how would i go about doing that? im a php noob lol
Quickbrown
In order to use default images when no post thumbnail available, replace with <?php if (has_post_thumbnail()) {the_post_thumbnail()} else {echo '’;} ?>
Then put a default-image.jpg under your themes’ image folder.
rulethenation
i cant get this to work, it just messes up my whole layout near the comments, am i missing something? i had to take it off my site

My posts are now enriched thanks to you and this tutorial.

HI!
Thanks for this information! This is exactly what I was looking for.
Is there a way to add an excerpt to this, along with the photo?
Thanks again for your help!
Editorial Staff
Yes. Just add the_excerpt(); where you want it to display excerpt.
Administrator
Jez
Thanks for this, exactly what I was looking for! I love how straight to the point your articles are, no confusion.
Omer Greenwald
Thanks for sharing. I’m using this code for a while now but it has a problem: when adding tags to a post, WP sorts them alphabetically regardless of the priority I added them. So this code displays related posts matching the first tag only which are less relevant sometimes.
Maybe you have an idea how to prevent this auto sorting of tags by WordPress or any other solution?
Editorial Staff
It is not using the first tag. This code is using all tags from the posts to find related posts.
Administrator
Clarence Johnson
I’m experiencing the same issue too.
Doug C.
All that first code did was put two instances of the same post on the page. It didn’t show any related anything.
Editorial Staff
Doug please contact us using the form with a live link example, and we can help. We know this code is working because a few of our client’s site is using it.

Great tutorial. Would someone mind showing me a working single.php with this code?

Unfortunately
Parse error: syntax error, unexpected T_ENDIF in C:\xampplite\htdocs\mock\wp-content\themes\scwd\single.php on line 76

Here is a working example Flowtown Blog.
Note that this code is so it will work inside the loop. Where are you trying to post this? If it is outside the loop then just add the end if code endif; << like that.

Don’t know what could be going wrong. After the clearfloat class it should work fine. That is how we put it in flowtown and it is working perfectly.

I will finish the theme and try it on a live site instead of xamp. I will let you know.
