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.

  3. 8MEDIA

    amazing post ,, thanks :D

  4. shaileshtr

    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.

  5. 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?

  6. AmandaLong

    This rocks … Thanks!

  7. 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!

  8. 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.

  9. 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.

  10. 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

  11. 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.

  12. 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??

  14. xavpro

    hey,

    great post! maybe you could help me:

    i have a auto thumb if none is defined,

    if ($thumb_array[’thumb’] == ”) $thumb_array[’thumb’] = ’link to your default thumbnail image’;return $thumb_array;

    now my question is how to define a thumb for each category, which will be used if none is defined at post.

  15. dehahs

    works nicely, thanks for sharing!

    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.

      Administratör

  19. titusmagnet

    Thanks..im searching for this kinda Code

  20. 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

  21. 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.

      Administratör

  22. 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…

      Administratör

  23. Hetal

    Thanks for this article. I was wondering if there is a way to auto-tag posts without having to manually enter them.

  24. Sisko

    Great!
    What if I want to display related posts by category without thumbnails?
    Thanks

  25. Terry

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

  26. Adrian

    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.

  27. 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!!!

  28. usman

    I was searching for related post with thumbnails plugins but the code that you paste above, solve my problem.

  29. 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’
      );

    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.

      Administratör

      • 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 :)

  31. John

    Nevermind, I got it figured out. Thanks for the post!

      • John

        I didn’t have any other posts with the same tags, i.e. no related posts. Dummy mistake.

  32. 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

  33. 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!

      • 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.

  35. 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.

      Administratör

  36. Anthony

    Is it possible to exclude a category from this module ?

    Thanks a lot,

      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!

  39. 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.

      Administratör

        • 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.

  40. 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

  41. Heather Hill

    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.

      Administratör

  42. Jez

    Thanks for this, exactly what I was looking for! I love how straight to the point your articles are, no confusion.

  43. 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?

  44. 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?

    I’m still learning php.

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

    • Editorial Staff

      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.

      Administratör

        • Editorial Staff

          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.

        • Liam

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

  47. Shahab

    Nice tutorial!
    Right now i am using YARPP but would love to give this a try!
