  • Hi @frazecolder

    You could create a text field in your backend to hold the sum of prices which would get populated dynamically and then post this value on the frontend.

    You can make use of the acf/load_field filter like so:

    function my_acf_load_field( $field ) {
        //get the value of the price field
        $value = $_POST['acf']['field_key'];
        $fee = '20';
        $sum = $value+$fee;
        $field['value'] = $sum;
        return $field;
    // name
    add_filter('acf/load_field/name=my_select', 'my_acf_load_field');
