Question

I have this code

add_action( 'delete_post', 'my_delete_function' );
 function my_delete_function() { 
   global $wpdb;
   $wpdb->query("
    DELETE FROM wp_votes WHERE post=".$thePostID."
;);
 }

How can I get the id of the post being deleted?

Additionally, will this still work if multiple posts are deleted in the admin?

Answer 1

The hooks automatically pass the deleted post id into your function, so you can just catch that, check the docs here:

add_action( 'delete_post', 'my_delete_function' );
function my_delete_function($postId) { 
   global $wpdb;
   $wpdb->query("
       DELETE FROM wp_votes WHERE post=".$postId."
   ;);
}
