Hi @debosseta

If you want to use post revision, I suggest you get in touch with WordPress community instead for better support.

Another method would be using a number field that will hold the total count. Then you can update the total count by using the acf/save_post hook like this:

function my_acf_save_post( $post_id ) {
    
    if( get_post_type($post_id) == 'orders' ){
        
        // Set the required field name and keys
        $select_field_name = 'select_field_name';
        $select_field_key = 'field_1234567890abc';
        $number_field_name = 'number_field_name';
        $number_field_key = 'field_abcdefghij123';
        
        // Get the old data from database and the new data (posted data)
        $old_select_value = get_field($select_field_name, $post_id);
        $new_select_value = $_POST[$select_field_key];
        
        // If the value changed
        if( $old_select_value != $new_select_value ){
            
            // Get the total count from the database
            $old_count = get_field($number_field_name, $post_id);
            
            // Change the posted data to make sure it's correct
            // This will be saved automatically later
            $_POST[$number_field_key] = $old_count + 1;
        }
        
    }
    
}

// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);

You can also disable the field by using CSS so the value can’t be edited from the backend.

If you want to have timestamps, I suggest you use the repeater field instead.

I hope this helps 🙂
