I'm trying to add a function when a post is delete.
I need to update a custom field value of a post when another post is deleted.
I've add in my function.php this function:

add_action( 'before_delete_post', 'myfunc' );
function myfunc( $postid ){
   $key_1_value = update_post_meta( 841, 'wpcf-priority', 3 );
}

But that code not works.

I can't be able to find the issue. Can you help me please?

Hello. Thank you for contacting the Toolset support.

Well - are you deleting posts from Trash? Could you please share more information from where you are trying to delete the posts - from backend (admin) or front-end?

Hi Minesh,
I delete posts form FRONT END using cred_delete_post_child button.

Well - the hook before_delete_post will only work when you try to delete the post permanently I mean when you delete posts from Trash.

Please check the following note:

It's important to note the hook runs only when the WordPress user empties the Trash. If you're using this hook note that it will not fire if the user is deleting an Attachment, since attachments are force deleted, i.e., not sent to the Trash. Instead use the delete_post() hook.

I've tried to do that, but not working yet....

add_action( 'delete_post', 'myfunc', 10 );
function myfunc( $postid ){
   $key_1_value = update_post_meta( 841, 'wpcf-priority', 3 );
}

Can you provide me a working piece of code please?

Thanks,
M.

Well - you should use the hook 'post_updated' and check if post_status changed to trash , then run your code.

For example:

function check_values($post_ID, $post_after, $post_before){

          if($post_after->post_status == 'trash'){
                  $key_1_value = update_post_meta( 841, 'wpcf-priority', 3 );
          }


}
add_action( 'post_updated', 'check_values', 10, 3 );

I've tried to add that piece of code, but nothing appened. I've tried alse to avoid if statement and do the update_post_meta function outside the if.

But the value priority of my post with ID 841 doesn't change...

I've also tried this hook:

add_action( 'trash_post', 'function_to_run_on_post_trash' );

from: https://codex.wordpress.org/Plugin_API/Action_Reference/trash_post

But I still have the issue..

*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.

I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).

I have set the next reply to private which means only you and I have access to it.

Could you please check now. I've added the following code to your current child theme's functions.php file:

function check_values($post_ID, $post_after, $post_before){
 
          if($post_after->post_status == 'trash' and $post_after->post_type=='slide-ipad'){
                  $key_1_value = update_post_meta( 969, 'wpcf-ordine-ipad', 9 );
          }
 
 
}
add_action( 'post_updated', 'check_values', 10, 3 ); 

Now, I can see that when I've deleted one entry - the last entry textbox value updated and displays 9. You can see that here:
=> hidden link

Perfect! It works, thank you so much!
So the problem was the plugin to add php functions?
