    Hi. Thank you for a great plugin.

    I'm using your plugin to create a post review system. I have a clonable group field like this:

    Criteria 1, Score 1
    Criteria 2, Score 2
    Criteria 3, Score 3

    ...

    I also create a hidden field called Total Score

    I wanna get Total Score = (Score 1 + Score 2 + Score 3 + ...) / n where n is the number of subfields in above group.

    Is there a way to alter value of Total Score before the post being saved?

    I'm a theme developer and I'/ good at filters & actions.

    Thank you so much.

    After digging into your code, I found the solution myself.

    Here's the solution for those who need:

    // there's a filter to alter value before post being saved
add_filter ( 'rwmb_NAME_value', 'somefunction' );

function somefunction() {

// get data
$get_data = isset( $_POST['SOMEKEY'] ) ? $_POST['SOMEKEY'] : null;

// do something with your data, multiple by 100 for instance
$modified_data = $get_data *100;

// return the modified data
return $modified_data;
}

    Anyway thank you for crafting many hooks for ease of use.

    Cheers.

    Glad that you find it! That's the correct way to do that. For more information about hooks, please look at this documentation.
