WordPress’te Yazı Küçük Resimleri Nasıl Eklenir

Editoryal Not: WPBeginner üzerindeki ortak bağlantılardan komisyon kazanıyoruz. Komisyonlar, editörlerimizin görüşlerini veya değerlendirmelerini etkilemez. Editoryal Süreç hakkında daha fazla bilgi edinin.

Yazı Küçük Resimleri her geçen gün daha popüler hale geliyor. Birçok dergi teması, daha sonra ana sayfada veya gönderi sayfasında gösterecekleri belirli bir gönderiyle bir görüntü ilişkilendirir. Hem yazı sayfasında hem de kategori sayfasında yazılarımızla birlikte bir küçük resim gösteriyoruz. Eski sürümlerde bu işlevsellik, çok kullanıcı dostu olmayan özel alan yönteminin kullanılmasıyla elde ediliyordu. WordPress Çekirdek Geliştiricileri sayesinde WordPress 2.9’daki birçok önemli özellikle birlikte bu işlev de çekirdeğe eklendi.

Sadece videoyu izleyin veya aşağıdaki öğreticiyi okuyun :)

Video

Yeni Başlayanlar İçin Rehber

WordPress Panosundaki Yazı Yaz Panelinizin kenar çubuğunda buna benzer bir seçenek göreceksiniz.

Post Thumbnails in WordPress

Bağlantıya tıkladığınızda bir resim yükleme sayfasına yönlendirileceksiniz. Resmi yüklediğinizde şuna benzer bir şey göreceksiniz:

Post Thumbnails in WordPress

Küçük resim olarak kullan yazan bağlantıya tıklamanız yeterlidir. Bunu yaptığınızda, aşağıdaki gibi bir ekran göreceksiniz:

Yukarıdaki ekran, işinizin bittiği anlamına gelir. Yayınla’ya tıkladığınızda görsel sitenizde gösterilecektir.

Geliştirici Kılavuzu

Bu işlevsellik çekirdeğe eklenmiş olsa da her kullanıcı bu seçeneği yazı yazma panelinin kenar çubuğunda göremeyecektir. Bu, yalnızca tema destekliyorsa etkinleştirilebilen işlevlerden biridir. Eski ücretsiz temalar bunu desteklemeyebilir, bu nedenle geliştiriciden güncelleme yapmasını istemeniz gerekir veya bu öğreticiyi izleyerek bunu kendiniz yapabilirsiniz.

Öncelikle temalar klasörünüzdeki functions.php dosyanızı açmanız ve aşağıdaki kodu yapıştırmanız gerekecektir:

add_theme_support( 'post-thumbnails' );

Bu kod hem yazılar hem de sayfalar için tema desteğini etkinleştirecektir. Yani artık kontrol panelinizde bir seçenek görebileceksiniz. Ancak temalarınızda görüntülenmeyecek çünkü kodu henüz temaya eklemedik.

Bu kodu kullanarak küçük resmi Döngü içinde herhangi bir yerde görüntüleyebilirsiniz:

<?php the_post_thumbnail(); ?>

Bu temel işlevdi, ancak yazı küçük resim boyutunu belirtmek gibi daha ileri düzeylere ulaşmak istiyorsanız, functions.php dosyanızı açmanız ve kodu aşağıdaki gibi yapıştırmanız gerekir:

add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 50, 50, true );

Boyutlar şu sırayla ayarlanır: genişlik x yükseklik ve bunlar pikseldir.

Bu satırı ekleyerek öne çıkan görseliniz için ek görsel boyutları da ekleyebilirsiniz:

add_image_size( 'single-post-thumbnail', 590, 180 ); // Permalink thumbnail size

Daha sonra belirli küçük resim boyutlarını gönderi döngüsünde şu şekilde çağırabilirsiniz:

<?php the_post_thumbnail('single-post-thumbnail'); ?>

Bu, bu özelliğin tam işlevselliğinin kırılmış versiyonudur. Herkesin takip edebilmesi için basit tutmaya çalıştık. Bu işlevsellik hakkında daha fazla bilgi istiyorsanız, göz atın:

    Is this necessary with Genesis Child Themes. They seem to have a featured image for their posts already. Thanks

  3. Kathleen Smitheram says

    So… I tried this and I think I broke my site. I now get this error

    Parse error: syntax error, unexpected ‘”‘ in /home/content/21/10729521/html/wp-content/themes/desk-mess-mirrored/functions.php on line 642

    and can’t get into my dashboard. I’m new to self-hosting and I have no idea how to fix this. HELP!

  4. Drew says

    Hi,

    Thanks for this post it totally helped me out!

    Question, now how would I also show the featured image (in a different size) within the actual post only (not in the loop)?

    Thanks :)

    • Mimo says

      Ignore my comments. I figured out why you wouldnt want to wrap them in img and anchor tags :D.

      Thanks for the post

    Keep writing, continue to inspire, to keep creating I like the idea and the website is fairly easy to use. I do wish that they would review more than the top 20 or so websites in the field. The web is a big place.

    Thanks for posting this info. I just want to let you know that I just check out your site and I find it very interesting and informative. I can’t wait to read lots of your posts.

  8. lakkolmahendra says

    Thank you very much for the wonderful information. It’s simple method to add thumnail in your homepage. I’ll try for my site today.

  9. LukeSwenson says

    I’m working on WorPress Version 3.2.1. I noticed that the module in the admin reads “Featured Image” rather than “Post Thumbnail.”

    Also, I get the following error when I try to add an image in the admin:

    Warning: Cannot modify header information – headers already sent by (output started at /——–/—-/——/——-/wp-content/themes/html5/functions.php:58) in /Applications/MAMP/htdocs/justine/wp-admin/async-upload.php on line 2648

  10. SagivHaalush says

    @wpbeginner Hey :) VERY(!) helpful post, However I got to the exact same problem after adding the 2 lines(at the bottom…). When I put them at the beginning, nothing happens…

    Can you please be more specific as for the placement in the loop(Which/where)? Thanks :)

  11. birdhammer says

    Hi there, I just tried to enter the code above by following instructions in the video, but when I updated it I got a parse error. I cannot even log into my dashboard. I feel like an idiot!

    I use wordpress with modularity lite theme and my site is birdhammer.com.

    Can you please help me?

  12. wpbeginner says

    The placement of the code in your functions.php file is probably causing the errors. Are you using a theme framework? Are you adding it way at the bottom??

  13. CaseyDennison says

    mines not working at all i keep gettin errors in the php and it is written up correctly. i dunno is screwed it keeps showing the functions code at the very top of my wp dashboard ??? thats weired

  14. davede says

    @wpbeginner Ah thanks, I resolved the problem. details here: (well seems i can’t paste a url in). that sucks.

  15. davede says

    Good stuff.Thank you.

    I’m having a hard time having the thumbnail appear only in the excerpt not on the post page.

    any ideas?

  16. wpbeginner says

    @kevin.m.kwok Yes, this sounds like a CSS issue. Your image css class needs to have float: left property.

  17. kevin.m.kwok says

    Hello, great tutorial. Everything works, except I can’t get the thumbnail to post “left” of my post on my homepage. It always goes on top of my post, even if I select left in the thumbnail options. Any Ideas?

  18. Peter Wolff says

    Hi WP Beginner.

    Great WP tutorial above from the Editorial Staff!

    I have a quick WP thunmbnail gallery page photo question. I’ve been trying to add some simple Custom Field php code to my Catefory.php template in order to add a small text caption title below each thumnail image. Very frustrated…anyway, I have attached below the Category.php thumbnail loop and was wondering if you can help me write the a Custom Field php code (field called “thumb_tag”) within this loop. Here’s the code:

    ID, ‘main_image’, true); ?>

    <a href="” ><img src="/resize.php?w=162&h=105&file=” alt=”” title=”” width=’162′ height=’105′ />

    Thank you very much!

    Pete

  19. shivam says

    i am new to wordpress,not knowing too much programming..i liked ur article.but can u tell me exact at which position we have to place this code..like fuctions.php is a file,which we have to edit,at what place we have to add that code,is there any demo for that?

  20. mark says

    Great tutorial – However, and I cant find this information anywhere – BUT, I want to add the thumbnail to the post-editor screen so that my writers can see what it would look like inline with the post before they publish. Where could I do that? Thanks in advance.

    • Editorial Staff says

      You see the thumbnail once you upload it, however there is no live preview on the admin screen. Your author can simply click Preview and see the post in the new tab <<

    Hi
    Thank you for the info. i followed the steps in my theme, however my pictures still do not show in the image box…they look like broken files on my Home page. When I click on them, then they appear. How can i make them visible on the home page? Thanks

  22. janine says

    Thanks for the great post – specifically about add_theme_support( ‘post-thumbnails’ ); – It worked great with the wootheme I am modifying

  23. saBEE says

    Thank you for the great information.

    Each of my posts has a photo. I am trying to get each post’s photo to show up as a thumbnail in the RSS feed. Will the above method work to do this?

  24. Bernard says

    I’ve gone through the steps in this tut, but for some reason I get the following error whenever I try to select an image from the gallery option:

    Fatal error: Call to undefined function: get_post_thumbnail_id() in /wp-admin/includes/media.php on line 1292

    Can anyone help me in sorting this out?

    thanks
    Bernard

  25. darren says

    is this actually cropping the image on upload? Or does it just display it at the appropriate height and width when it calls it on the page? I ask b/c we pull our feed from our blog onto a non wp site and link back to it but would like to be able to reference the thumbnails. It is a asp site so I don’t have the luxury of php’s native image manipulation

  26. Helen says

    Hello
    We have this code in theme functions (it came with theme skin) the theme has a image slider that uses the ‘post thumbnail’ function. yet it doest show in admin so we cant get slider to work;

    <?php

    help : ) thank you

  27. Ami says

    works great!! just one query.. how can i add a link or wrap a link around

    so that when someone click the link a lightbox opens with the original size.

    Just to clarify.

    At the moment in functions.php I have

    add_image_size(‘my-custom-image’, 640,9999); so the image in the post is 640 in width, this will then be linked to the original image which is say 1000px by 500px.

    I did find this: http://polymathworkshop.com/shoptalk/2010/03/19/get-the_post_thumbnail-direct-path-for-wordpress/ which works to a degree but opens the thumbnail in the lightbox.

  28. Eduardo Antunes says

    Cool!

    To remember:

    > add in functions.php

    add_theme_support(‘post-thumbnails’);
    set_post_thumbnail_size(70, 70, true);

    > add in the loop:

    php the_post_thumbnail();

  29. Ricky@twitter apps says

    Weel I was looking for the same thing. I have a quick question for ya. Is there any way to have default image of the category to show as a thumbnails? Or is there anyway to fetch first image of the post and use it as thumbnail as related post.
    I implemented the above technique on my blog but the major problem is my all the posts doesn’t have thumbnail enabled. Which makes the situation horrible as I have to update all the post with thumbnail.
    Is there anyway to use first image as default thumbnail using above technique?

  30. Jal says

    Editors,

    Do you use the wordpress’s post editor or some offline blog publishing software? I use Live Writer which has some decent options but sometimes I think of a switch-over to Wp’s post editor. Can you share some views on this please?

    Thank you

  31. Antonio says

    Wow thanks I’ve always wondered how to do this but never really had the patience to look for a solution. I didn’t know it was this simple. WOOOOT! Thanks. :)

  32. Trisha says

    Any idea if this works for Page thumbnails? I’m trying to list child pages using this code. (the 2nd one, in ‘post format’. Switched out all instances of ‘content’ with ‘excerpt’ and used Andrew Oz’s Excerpt Editor which is seriously cool.

    When I try to plug in the code for the thumbnail, it doesnt show.

    Any idea what I might be doing wrong?

  33. Cosmin says

    Guys, does this only work with square images?

    As in 50px by 50px?

    I heard someone mention it only takes the height value when specifying dimensions…
    (so 50px by 30px wouldn’t work)

    • Editorial Staff says

      It will work with any size. Sometimes the image quality will be lost if it is not the right ratio. We have it working on a client’s website and it works perfectly fine.

      Yönetici

  34. Luke says

    I’m a beginner and love what you’re doing. Would be nice to get very specific instructions for stuff like this. When I copy/paste to functions it doesn’t work.

    Thoughts on what I could be doing wrong? Maybe a functions for beginners post?

    Thank you and keep up the great work.

    • Editorial Staff says

      Are you using WordPress 2.9? If so then there is no way that it would not work. This is probably the best break down of this code.

      While we try to make everything as clear as possible, sometimes it requires prior knowledge to complete some tasks.

      If you want one of our staff to take a look and do this for you we can do it for a small fee.

      Yönetici

  35. Cosmin says

    Sweeeeeet!

    Thanks guys, perfect timing, as I’m working on a WordPress theme for a client and it requires just this!

    Now it will be sooo easy for the less-tech-savvy person that’ll write posts :)
