How to delete all the post_object fields when a post item is deleted.
I.e. if you have a repeater, where one of the columns is a post_object referencing a post from your blog. If later on I delete the post from the blog, how can I delete all the references on ACF to it.
I was thinking on something like this:
add_action('delete_post', 'my-function-on-delete');
function my-function-on-delete($post_id) {
$post = get_post($post_id);
if ($post->post_type == 'my-custom-post-type') {
//My function
}
}
The thing left is how do I delete all the ACF entries that contain the $post_id ?
Thanks for your time.
Hi @aldoreyes
This is a bit of a tricky one, but is possible with some logic as such:
1. Search the wp_postmeta table for any rows which have a value of $post_id
2. Delete these rows!
The database query will have to be a custom FIND sql statement, but this is easy to create thanks to the wpdb functions. You can read more about this here:
