Hello.
You will be need to make this customization.
1) Please open this file ../booking/

then find this code:
// Check if dates in range format and fix it to the coma seperated dates function createDateRangeArray($strDateFrom,$strDateTo) {

and replace it to this code:

// Return the number of days between the two dates: function getbkDatesDiff ($d1, $d2) { return round( (strtotime($d1)-strtotime($d2))/86400); } function getbkSortedDates($booking_days) { if (strpos($booking_days,' - ')!== FALSE) { $booking_days =explode(' - ', $booking_days ); $booking_days = createDateRangeArray($booking_days[0],$booking_days[1]); } $days_array = explode(',', $booking_days); $only_days = array(); foreach ($days_array as $new_day) { if (! empty($new_day)) { $new_day=trim($new_day); if (strpos($new_day, '.')!==false) $new_day = explode('.',$new_day); else $new_day = explode('-',$new_day); $only_days[] = $new_day[2] .'-' . $new_day[1] .'-' . $new_day[0] . ' 00:00:00'; } } if (! empty($only_days)) { sort($only_days); } return $only_days; } // Check if dates in range format and fix it to the coma seperated dates function createDateRangeArray($strDateFrom,$strDateTo) {

2) Please open this file ../booking/inc/biz_s.php

then find this code:

$summ_deposit = apply_bk_filter('fixed_deposit_amount_apply', $summ , $booking_form, $booking_type );

and replace it to this code:

$summ_deposit = apply_bk_filter('fixed_deposit_amount_apply', $summ , $booking_form, $booking_type, $booking_days_count );

3) Please open this file ../booking/inc/biz_m.php

then find this code:

$summ_deposit = apply_bk_filter('fixed_deposit_amount_apply', $summ_total , $_POST['form'], $_POST['bk_type'] );

and replace it to this code:

$summ_deposit = apply_bk_filter('fixed_deposit_amount_apply', $summ_total , $_POST['form'], $_POST['bk_type'], $_POST[ "all_dates" ] );

4) Then find this code:

function fixed_deposit_amount_apply($summ , $post_form, $booking_type ) { $original_summ = $summ; // Original cost for booking

and replace it to this code:

// Apply fixed deposit cost to the cost from paypal form function fixed_deposit_amount_apply($summ , $post_form, $booking_type , $booking_days = false ) { if ($booking_days !== false) { $sortedDates = getbkSortedDates($booking_days); if ( ! empty($sortedDates) ) { $dates_diff = getbkDatesDiff('+6 weeks', $sortedDates[0]); if ($dates_diff > 0) return $summ; } } $original_summ = $summ; // Original cost for booking
