Recentemente uno dei nostri lettori ci ha chiesto come rimuovere di massa le immagini in evidenza dagli articoli in WordPress. Su WPBeginner abbiamo parlato molte volte delle immagini in evidenza (miniature degli articoli). Vi abbiamo mostrato come aggiungere immagini in evidenza in WordPress, come aggiungere nuove dimensioni di immagini in WordPress, come rigenerare le miniature, e vi abbiamo anche mostrato come aggiungere più immagini in evidenza a un articolo in WordPress. In questo articolo vi mostreremo come rimuovere di massa le immagini in evidenza dagli articoli in WordPress.
Il problema della rimozione di massa delle immagini in evidenza o delle miniature degli articoli
Purtroppo, in modo predefinito è possibile rimuovere le immagini in evidenza solo modificando ogni articolo e rimuovendo l’immagine in evidenza. Se un utente ha centinaia di articoli con immagini in evidenza, rimuoverle una per una può richiedere molto tempo. Proviamo invece un approccio diverso. Eseguiremo una query del database e toglieremo le immagini in evidenza su tutti gli articoli.
Prima di procedere, notate che il codice sottostante rimuoverà le immagini in evidenza da tutti gli articoli del vostro sito WordPress semplicemente incollandolo. Si noti anche che questo codice non elimina nessuna delle immagini caricate, che saranno ancora disponibili nella Libreria dei media e potranno essere riutilizzate in qualsiasi momento.
Tutto ciò che dovete fare è copiare e incollare questo codice nel file functions.php del vostro tema.
global $wpdb;
$wpdb->query( "
DELETE FROM $wpdb->postmeta
WHERE meta_key = '_thumbnail_id'
" );
Tutto-in-uno. Non appena si salva il file functions.php, questo script eseguirà una query al database e rimuoverà le immagini in evidenza da tutti gli articoli.
Importante: NON SI TRADUCE questo codice subito dopo aver salvato il file functions.php. Non sarà possibile impostare immagini in evidenza in WordPress, poiché questo codice continuerà a rimuovere le immagini in evidenza dagli articoli.
Speriamo che questo articolo vi abbia aiutato a salvare un po’ di tempo e vi abbia permesso di rimuovere di massa le immagini in evidenza dagli articoli di WordPress. Per domande e feedback, lasciate un commento qui sotto.

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

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
Thank you! It is an excellent advice to remove all featured images
Jax
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
#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
Thanks a lot, you helped me saved a lot of time.
Rahul
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
You will have to delete images from media library.
Admin
Rahul
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
Is it possible to query a specific category and remove just those categories posts featured images?
Biriisi
Thanks man!!

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
Justin, we tested the code again. It does not delete files from your media library or your server. It just unsets featured images.
Admin
Sudip
I am facing the same problem. After adding this code, few images are being erased from media library.
WPBeginner Support
Sudip, thank you for notifying us. We have updated the article. Please try the new code instead.

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
Yes this is correct. However, the query can be modify to exclude certain post types.
Admin
James DiGioia
Wouldn’t it be easier to just run a query on DB directly?
WPBeginner Support
Yep, and this is exactly what this code is doing.
