Hi woutervanerp,

The acf/save_post action should help you here.

This code should suffice for what you want, though I haven’t tested it:

<?php

function my_acf_save_post_callback( $success ) {
    // Do what you'd like here
}

function my_acf_save_post( $post_id ) {
    if ( !isset( $_POST['acf'] ) ){
        return;
    }

    $fields = $_POST['acf'];

    add_action( 'acf/save_post', function( $post_id ) use ( $fields ) {
        remove_action( 'acf/save_post', $this );
        $db_fields = array();
        foreach( $fields as $field_key => $value ) {
            $db_fields[$field_key] = get_field( $field_key, $post_id );
        }
        // Serialize the value arrays from $_POST and the Database, so that they are single-level arrays, and array_diff_assoc them to generate the array of differences...
        $success = empty( array_diff_assoc( array_map( 'serialize', $fields ), array_map( 'serialize', $db_fields ) ) );
        my_acf_save_post_callback( $success );
    }, 11 );
}

add_action( 'acf/save_post', 'my_acf_save_post', 9 );

?>

EDIT:

Actually, that would work for a form save, but not for update_field or add_row, which works entirely server-side.

Code Update:

function my_acf_update_field_wrapper( $field_key, $value, $callback, $post_id = null ) {
    $new_values = array(
        $field_key => $value
    );

    // We need to hook the default WordPress save_post action
    add_action( 'save_post', function( $post_id ) use ( $new_values ) {
        remove_action( 'save_post', $this );
        $db_fields = array();
        foreach( $new_values as $field_key => $value ) {
            $db_fields[$field_key] = get_field( $field_key, $post_id );
        }
        // Serialize the value arrays from $new_values and the Database, so that they are single-level arrays, and array_diff_assoc them to generate the array of differences...
        $callback ( empty( array_diff_assoc( array_map( 'serialize', $fields ), array_map( 'serialize', $db_fields ) ) ) );
    } );
    if ( $post_id == null ) {
        update_field( $field_key, $value );
    } else {
        update_field( $field_key, $value, $post_id );
    }
}

function my_acf_save_post_callback( $success ) {
    // Do what you'd like here
}

function my_func() {
    // We need to update a value here
    my_acf_update_field_wrapper( 'field_abcdef123456', 'new-value', 'my_acf_save_post_callback' );
}
