Trying to check if a field is updated and if it is perform a function but can’t get it to work. Here is my code:

function smsemail_update( $post_id ) {

        $user_new=$_POST['user_new'];
    $user_saved=get_field('user_new', $post_id);

        
if  ($user_saved==$user_new){
}

else {
MY FUNCTION...
}
}
add_action( 'acf/pre_save_post', 'smsemail_update' );

Any ideas?

Hi @almemedia

The acf/pre_save_post is a FILTER which is only run from the front end form. This allows the $post_id variable to be modified.

Perhaps you would be better off attaching your custom code to a filter on the acf/update_value. Please read the docs for this filter to see how you can use it.

Thanks
