最近、ある読者から「WordPressで投稿のアイキャッチ画像を一括削除するにはどうすればいいですか？WPBeginnerでは、何度もおすすめ画像（投稿サムネイル）について説明してきました。WordPressでおすすめ画像を追加する方法、WordPressで新しい画像サイズを追加する方法、サムネイルを再生成する方法、WordPressで複数のおすすめ画像を投稿に追加する方法までご紹介しました。今回は、WordPressの投稿からアイキャッチ画像を一括削除する方法をご紹介します。
投稿サムネイルやおすすめ投稿画像の一括削除の問題点
Imagelyの初期設定では、各投稿を編集してアイキャッチ画像を削除するしかありません。もしユーザーが何百もの投稿でアイキャッチ画像を使用している場合、1つ1つ削除するのは非常に時間のかかる作業になります。そこで、別の方法を試してみましょう。データベースのクエリーを実行し、すべての投稿のアイキャッチ画像を削除します。
先に進む前に、以下のコードを貼り付けるだけで、WordPressサイトのすべての投稿からアイキャッチ画像が削除されることに注意してください。また、このコードによってアップロードした画像が削除されるわけではなく、メディアアップローダーで利用可能なままなので、いつでも再利用することができます。
このコードをテーマのfunctions.phpファイルにコピー＆ペーストするだけです。
[cbk1］
すべてです。functions.phpファイルを保存するとすぐに、このスクリプトがデータベースクエリーを実行し、すべての投稿からアイキャッチ画像を削除します。
重要：functions.phpファイルを保存したら、すぐにこのコードを削除してください。このコードは投稿からアイキャッチ画像を削除し続けるので、WordPressでアイキャッチ画像を設定することができなくなります。
この投稿が、WordPressの投稿からアイキャッチ画像を一括削除し、時間を節約するのにお役に立てば幸いです。ご質問やご意見がありましたら、以下にコメントをしてください。

This little line of code saved me a lot of hassle. Thanks for that! I had imported about 50 articles and WordPress was saying each one had a featured image when it did not have one.
I already know why it was doing that…long story…however, how am I to remove the featured image when there is nothing to remove?? Just paste these lines of code into the functions.php file like the article says and voila! All ghost images removed
wpbeginner makes me SO happy

Deleting all the server images assigned to the thumbnails is relatively simple, now, how to condition to delete all uploads not used by the server as featured images? This should be the most interesting, clean the images not used by the system, in order to polish the machine resources deleting junk images, not used.
Peter says
Yes! So helpful, thank you!!!

Followed the instructions to the letter. Got this error message: Parse error: syntax error, unexpected ‘$wpdb’ (T_VARIABLE) in /home/ruznnjep/public_html/wp-content/themes/natalie/functions.php on line 411
Blog broken. Had to reinstall. Thanks.
Dan says
Thank you! It is an excellent advice to remove all featured images
Jax says
Is there anyway to undo this? I didnt realise it would remove thumbnail images as well. I have tried restoring the thumbnails but it is not working. Thanks
Mike says
#1. Are we 100% positive that the current code does NOT delete any images from my media folder? And simply “unset” them from featured image?
#2. You mention “However, the query can be modify to exclude certain post types.” Can you share the code I would use to avoid a category with ID=25?
Thank you so much,
Mike

After delete my related images my images from homepage desappeared, but when I go to post details it appears normally. Before run the script, the homepage used the images from inside the post and not from related images, so I really don’t know why they desappeared from my homepage. Do you have any idea why this happened?
Robin Solanki says
Thanks a lot, you helped me saved a lot of time.
Rahul says
Is there a plugin or codes to remove both post and images attached to a post when we delete it? I mean if i delete a post i also want to delete images related to that post also.
WPBeginner Support says
You will have to delete images from media library.
管理者
Rahul says
Wish someone would have made a plugin like that because deleting images from 100-200 posts is very time consuming… ?? if any plugin of that kind comes up pls do update it in ur site.. thanks for your reply
Nicholas says
Is it possible to query a specific category and remove just those categories posts featured images?
Biriisi says
Thanks man!!
Justin Edwards says
BEWARE
I used this code yesterday to try to delete the featured images as part of an upgrade to a new WordPress theme. While it did delete the featured images from posts, it also deleted them from the media library and I think it’s also deleted the original files from the server.
Having used this code to try and speed thing up, I now find myself having to re-install and re-link over 2,500 images for my site.
WPBeginner Support says
Justin, we tested the code again. It does not delete files from your media library or your server. It just unsets featured images.

Sudip says
I am facing the same problem. After adding this code, few images are being erased from media library.
WPBeginner Support says
Sudip, thank you for notifying us. We have updated the article. Please try the new code instead.
UaMV says
One should also note that this deletes featured images not just from standard post, but from all posts (including custom post types), correct?
WPBeginner Support says
Yes this is correct. However, the query can be modify to exclude certain post types.

James DiGioia says
Wouldn’t it be easier to just run a query on DB directly?
WPBeginner Support says
Yep, and this is exactly what this code is doing.
