Så här gör du Relaterade inlägg med inläggsminiatyrer i WordPress utan tillägg

Vill du visa en lista över relaterade inlägg på din WordPress website och föredrar att använda kod snarare än ett plugin?

När besökarna på din blogg har slutfört att läsa en artikel som de är intresserade av, kommer en lista med relaterade inlägg att hålla dem engagerade och hjälpa dem att hitta new content att läsa.

I den här artikeln kommer vi att visa you hur du visar relaterade inlägg med WordPress med hjälp av kod, utan något plugin obligatoriskt.

How to: Related Posts with Thumbnails in WordPress Without Plugins

Varför visa Relaterade inlägg i WordPress?

När din WordPress blogg börjar växa kan det bli svårare för användarna att hitta andra posts i samma ämne.

Att displaya en lista med relaterat content i slutet av varje blogginlägg är ett bra sätt att hålla kvar dina besökare på din website och öka antalet sidvisningar. Det bidrar också till att förbättra synligheten för dina viktigaste pages genom att ditt bästa content visas där folk lätt kan hitta det.

Om du ej är bekant med kod kommer du att tycka att det är enklare att välja ett av de många tillägg för relaterade inlägg i WordPress som kan visa relaterade inlägg utan kod.

Men om du någonsin har undrat om du kan visa relaterade inlägg utan att använda ett plugin, kommer vi att dela två olika algoritmer som du kan använda för att generera relaterade inlägg med inläggsminiatyrer med enbart kod:

Obs/observera: Om du vill visa en thumbnail med varje relaterat inlägg, se till att du först lägger till en featured image till dessa inlägg.

Metod 1: Hur man visar Relaterade inlägg i WordPress med Tags

Ett effektivt sätt att hitta relaterat content är att leta efter andra posts som delar samma taggar. Tags används ofta för att fokusera på de specifika detaljer som finns i ett post.

Med det i åtanke kanske du vill gå vidare och add to några gemensamma taggar till de posts du vill relatera till varandra. Du kan enter dem i ”Tags”-boxen i WordPress editor.

The ‘Tags’ Settings Box in the WordPress Editor

Följ efter att du har lagt till taggar till dina posts, nästa sak att göra är att add to följande code snippet till ditt temas single.php mall.

Om du behöver hjälp med att lägga till kod på din site kan du läsa vår guide om hur du klistrar in snippets från webben i 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();

Den här koden letar efter taggar som är associerade med en page och runar sedan en sökning i en database för att hämta pages med liknande tags.

Var ska du placera koden? Det beror på ditt theme, men i de flesta fall bör du kunna klistra in koden i ditt temas single.php template efter huvudinlägget och precis ovanför avsnittet med kommentarer.

Om du använder temat Twenty Twenty-One som vi gör på vår demo-site, är ett bra ställe att klistra in koden i filen template-parts/content/content-single.php efter headern och precis efter <?php the_content();.

Related Content by Tags Preview

Detta kommer automatiskt att visa relaterat content på alla WordPress-poster. Du måste ändra styling och appearance för dina relaterade inlägg för att matcha ditt tema genom att lägga till custom CSS.

Related Posts example

Tips: Istället för att editera dina theme-filer, vilket kan förstöra din website, rekommenderar vi att du använder ett code snippets plugin som WPCode.

WPCode gör det säkert och enkelt att add to custom kod i WordPress. Dessutom kommer det med ”Insertion” alternativ som låter dig automatiskt insert och exekvera snippets på specifika locations på din WordPress site, till exempel efter en post.

WPCode insertion options for custom code snippets

För mer detaljer, se vår guide om hur du lägger till custom code i WordPress. Du kan också kontrollera vår detaljerade WPCode-review för att lära dig mer om pluginet.

Metod 2: Hur man visar Relaterade inlägg i WordPress efter Category

Ett annat sätt att displayed relaterat content är att lista posts som är i samma kategori. Fördelen med den här metoden är att listan över Relaterade inlägg nästan aldrig kommer att vara tom.

Likes Method 1, you need to add a code snippet to your theme’s single.php template or in a code snippets plugin like WPCode. För mer detaljer, se Metod 1 och vår guide om hur du lägger till customize-kod i 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();

Nu kommer du att se en lista med relaterat innehåll längst ner i varje post.

Om du vill ändra styling och appearance på dina related pages måste du add to custom CSS för att matcha ditt theme.

    I was trying to correct WordPress-related posts but it was not happening when I saw this code and I used this code in my WordPressfile so now my WordPress-related posts coming properly

      Happy to hear our guide could help you!

    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.

  4. aman

    I want code to display random posts and pages with thumbnail

  5. karan4official

    Instead of using <? use <?php everywhere

    • WPBeginner Support

      Thank you for your feedback, this article should currently be using the php version everywhere :)

      Administratör

  6. Motahar Hossain

    Thank you for your nice post.

    Here ”ignore_sticky_posts” should be used instead of ”caller_get_posts”. Because ”caller_get_posts” is deprecated.

    • WPBeginner Support

      Thanks for pointing that out, we’ll be sure to look into updating the article :)

  7. Frank

    Can you direct me as to where to add what categories I would like to limit the related posts to?

    • WPBeginner Support

      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.

      Administratör

  8. Greg

    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

      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.

    Hi, is it possible to limit them by date? Show only those of the last year?

  11. Luis

    I found a way to make the smaller thumbnails, but it shows them in a column and not horizontally. How can this be modified?

  12. Luis

    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?

    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.

  16. Anthony Reese

    Thanks for the tutorial. This was incredibly useful and worked like a charm!

  17. pawan singh

    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?

  18. Ahmad

    really helpful, thanks !

  19. Tracy

    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

      I Agree. I have no idea where to paste this code too.

  20. Rose

    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

  22. Luan

    Hi,

    Thanks for your post. I added the code in content-single.php and it worked. However, it displays as 1 column not 3 columns like your example. Could you please help me on this? I want my related posts to be displayed in 1 row, 3 columns. Thanks so much.

    Hello!
    The first link on Aditional Sources, is broken.
    Thank you by the code.

  24. Abhijit Badgujar

    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?

  25. Gyuricza Laszlo

    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!
    Sincerely,

    Hi Syed. How do I style it?

    • WPBeginner Support

      Hi Tuta,

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

  28. Suraz

    How to Show Related Post It In two Columns Like here in WPBeginner??

  29. Tom

    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

      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.

  30. Zane DeVault

    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!

  31. may nghe len

    Let me ask the Code Related Posts by Category posted in public places. thank you

  32. atiq

    in Twentyfifteen default theme where should i insert this code in single.php file? If i inserted above the endwhile; it shows syntax error, unexpected ‘endwhile’ and if i inserted below the endwhile; but above the endif; it shows syntax error, unexpected ‘endif’

    Any solution for this?

    Thanks

    • Mohammad Kazemi

      You must use ’<?php' not '<?'

  33. atiq

    in Twentyfifteen default theme where should i insert this code in single.php file? If i inserted above the enwhile; it shows syntax error, unexpected ’endwhile’ and if i inserted below the enwwile but above the endif; it shows syntax error, unexpected ’endif’

    Any solution for this?

    Thanks

  34. Marcel Tripoux

    Hi! Great post!

    Is there a way to combine both option, in order to call related tags only in the current category ?

  35. Bambang

    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 :)

  36. Alex

    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.

  37. Mohammad

    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

  38. Muthu

    Dear collegue this is an error am getting while pasting this code on single.php file.kindly tell me exacctly where should i paste this code.

    Parse error: syntax error, unexpected end of file in C:\xampp\htdocs\beingusefull\wp-content\themes\TechPlus\single.php on line 78

  39. WPBeginner Staff

    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

      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=””>

  40. wiyono

    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

      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.

  41. Gretchen Louise

    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.

    • vipul

      can you tell where and how?

  42. Rachael

    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?

  43. kate // always craving //

    Hi, I must be the only one who is not doing this correctly. My theme supports featured images, I added this code before the comments within the single.php file. Any tips on exactly where to input in the code?

  44. Keyko Sakura

    All the codes I find never work. Or they don’t change anything on my page or they display an error message. I don’t know what else to do!

  45. Mason Coulter

    Is there a way to add pagination to the related posts query? I cant seem to get pagination to work on a secondary query within single.php. Thanks!

  46. Tom K.

    Hello , i want to ask , is there way to make , that related posts would be by category and tags in one place? Thanks.

  47. Jonas

    My thumbnails are too big, help. How can you limit the related posts thumbnails?

  48. Jonathan

    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

      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

      wait… no, that didn’t work :(

  49. Miro

    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

    • WPBeginner Support

      This sounds like a nice post idea, we will cover it soon in a new article. Thanks for the feedback.

      Administratör

      • Miro

        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.

  50. Caleb

    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.

    Thanks for the help :)
