I have this code

add_action( 'delete_post', 'my_delete_function' );
 function my_delete_function() { 
   global $wpdb;
    DELETE FROM wp_votes WHERE post=".$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?

I haven't tested so I'm providing you with two possibilities, Inside a loop, use the following:

$post_id = get_the_ID();

Outside a loop, use the following:

global $wp_query;
$post_id = $wp_query->post->ID;


global $post;
$post_id = $post->ID

Or you can pass the post ID in a function, much like

function my_function($post_id){
    // code

Inside the loop, it is probably best to use get_the_ID() – v0idless Jan 8 '12 at 16:15
Good point. I edited my answer. Thank you :) – Asko Jan 8 '12 at 16:22
There's no reason whatsoever to use a solution other than the one passed as a function parameter - all others are void and risk breaking! – TheDeadMedic Jan 8 '12 at 16:31

Add a parameter to your function, which will be passed the ID of the current post being deleted.

add_action( 'delete_post', 'my_delete_function' );
function my_delete_function( $post_id /* <- ID of post being deleted */ )
    global $wpdb;
    $wpdb->query( $wpdb->prepare( "DELETE FROM {$wpdb->prefix}_votes WHERE post = %d", $post_id ) );

Using any external variable (like a global in @Asko's answer) removes any guarantee that the post actually being deleted is the one you're working on within your function - it could either fail completely, or even delete data for the wrong post!
