  1. Hello,
    Is there a hint to show valuation days?
    For example, how can I show [original_cost_hint] - 10% discount for 7 days stay = new cost?
    Thank you

    • Hello.
      Unfortunately, there are no shortcode for showing cost before and discounted cost after.
      You can show only real booking cost, by using [cost_hint] shortcode.
      Please use shortcode generator at the right side of the Booking > Settings > Form page for the fast and correct creation of booking form fields shortcodes.

  2. Thank you .
    I see how to create shortcodes and I'm doing it successfully.
    But I don't see what kind of conditional hidden element on the form I could use to calculate the amount of the discount and its percentage(i.e: 10% for 1 week, 15% for 2 weeks)..

    Another question:
    I've checked the Advanced Cost box in Payment Settings
    I have a select box for extra beds in the room (10€/night) in the booking form
    I have a 10% discount for stays over 7 days and more
    Everything works well except the extra bed doesn't get discounted
    What am I doing wrong??

    • Hello.
      Discount for stays over 7 days and more it's configuiration of "Valuation days" at the Booking > Resources > Cost and rates page.
      Check more about this feature here: https://wpbookingcalendar.com/overview/#valuation-days
      Watch it in this video guide https://wpbookingcalendar.com/help/valuation-days-cost-video-overview/

      It's does not relative to the additional cost at the Booking > Resources > Advanced cost page.
      Such additional cost at the Booking > Resources > Advanced cost page useful, only if you need to set some additional cost depend from the selection of options in the booking form. Also please note, the additional cost, can not depend from the selected dates. it's can be only as fixed cost or as percentage from the total booking cost.
      Kind Regards.

      • Sorry, I didn't clearly explain
        2 things:
        1) I have a valuation day set for 10% after 7 days stay. It works fine
        My first question is: how can I make an invoice(in email) where the discount shows (i.e: 100€ - 10%discount for 7 day stay = 90€) ?

        2) I have an advanced cost for xtra bed (select box 1,2,3 at 10€.day per xtra bed). It works well.
        When I select 7 days stay, I get the discount on the room but not on the extra bed.
        My question is : how do I get the 10% discount also for this option and not just for the 7 days?

        • Hello.
          1) It's does not possible to show such cost in details. Sorry.
          You can show only total booking cost 90 EUR by using the [cost_hint] shortcode.

          2) It's also does not possible to apply such discount to the extra beds, if you have defined additional cost as fixed cost 10 EUR per bed.
          If you will set additional cost per beds as percentage, for example cost per 1 bed as 5% from total booking cost, so in this case, it's will work, of course. But based on fixed cost it's does not possible to apply such discount in 10% from days selection. Sorry.
          Kind Regards.

  3. Hello,
    we are having trouble with the results we obtain from a search template. We have different bookable items, some of them have only one single resource and others have various resources (different types of rooms). When searching for a specific date range we only get as a result those which have only one resource (as they show the booking calendar in their specific page), whereas those that show not the calendar, but a drop-down menu to choose the specific resource. It seems the template does not identify those, that have no calendar visible.
    How can we get the complete search results?

    Best regards

  4. Hello when I click on the calender icon while installing as a post the screen becomes grey. Does anybody had this?
    Thanks, Robert

    • Hello.
      Probably, its because of conflict with some other plugin or actual theme.
      Please try to deactivate one by one all your active plugins at the WordPress > Plugins menu and make testing after each plugin deactivation.
      If its not help, please deactivate all your plugins and active the default WordPress theme. And then retest it again.
      We just need to find the reason of this issue.

      Otherwise please configure the Booking Calendar shortcodes manually.
      Please read how manually to configure Booking Calendar shortcodes here https://wpbookingcalendar.com/help/booking-calendar-shortcodes/
      Kind Regards.

  5. I need to upgrade from the 2 site developer personal to the 2 site developer Business Small - how do I start that process. I purchased yesterday, how do I provide proof of purchase and pay the difference?

    • Hello.
      You can make upgrade to the higher version of Booking Calendar from your exist version of plugin by clicking on the “Upgrade” menu item at the top right side of General Booking Settings page in your admin panel.
      Kind Regards.

  6. Hi,

    has anybody else used the wpbc_api_is_dates_booked() function in the dev-api file to check an array of dates against existing bookings in a calendar resource. It works fine but is incrdibly slow! just checking 1 array of 7 dates takes multiple seconds to complete.

    What's making it so slow? And is there any way to speed it up? A different function? Or maybe hacking the code? We only need to check dates (not times).

    Any ideas?

    thanks, John

    • Hello.
      It's seems that  at these search  pages,  you are try  to  implement your own search  availability.
      I can suggest that  the issue at these pages,  does not relative to that  function  of checking dates availability,  but relative to  the type of requests that  you are sending. It's seems,  like you sending several  Ajax requests for each  property  and check in each  request if the dates available or not. If it's true,  so then  much  time each  request  can  take for sending and receiving and also  for checking in database,  of course.
      You need to  have one request  for searching availability  among all  booking resources, and then  send one response for showing all  your properties.
      Otherwise recheck your error.log in your server configuration, about any relative errors. If you can not find error.log file, please contact support of your hosting company about helping in finding this file.

  7. Hi,
    This solution has worked for us since i implemented it but today i got a call and for some reason it has stopped working, now you can only start bookings on mon - thur and bookings can not be longer than friday the same week. thus leaving the weekends unbookable.

    setting are dynamic days, min & max 8 days and start day of range is set to friday.

    then using the following shortcode for each day of the week.

    , {select-day condition="season" for="kop-laug" value="1-6,8"}, {select-day condition="season" for="kop-sunn" value="1-6,8"}

    any idea what might have happened and how i could fix it?

    • nevermind, figured it out 2 mins after i posted 🙂 seems someone was tinkering with things they do not understand 🙂

  8. Hi, Whenever I add the booking calendar widget to a page and publish I am no longer able to switch to the default visual editor. I am using the latest version of WordPress with Avada builder. I can't seem to figure out the issue

      Kind Regards.

  9. Hi,

    It would be nice to be able to select timeslots depending on input selects or radio buttons.
    For example:
    Radio button Option 1 and button Option 2
    depending on the selection by the visitor the available timeslots vary.
    Option 1: 10:00-10:30 10:30-11:00 11:00-11:30 etc
    Option 2: 10:00-11:00 11:00-12:00 12:00-13:00 etc

  10. Hi Support

    I have the Personal SingleSite version of the plugin. I have inserted a popup in the header with the overview of all the calendars. When inserting the calendar on the single product, it just gives the label "Calendar is loading...". I have read the article about already having a booking calendar on the website (https://wpbookingcalendar.com/faq/why-the-booking-calendar-widget-not-show-on-page/). I thought this was only for the free version. Is there any way to make the calendar appear on the single product pages? I have tried shortcodes, with the same result. I hope you can assist me in this regard.
