Taking Bookings with validation that prevent multiple booking for same day

    Hi,

    On our site we need to take bookings for a hall that can be booked for numbers of occasions, like the Birthday Party, Conference Meeting Room, Corporate Training, or for any such other purpose. We have a different landing page for all such purposes for SEO. However, we have the single hall as an inventory, so we can take a single booking per a day.

    Gravity form works well for all we need including payment, however we're unable to figure out how to make it validate if the hall is already booked for that particular day.

    I need some advise on how to prevent gravity form accept booking for any such day where it has been already booked, and allow booking only for the days where it is not booked. So its a date against which we might need to validate. But how to do it?

    Any idea?

    Thank you in advance.

    Displaying previous booking as mentioned here might also work...

    Are you allowing the visitors to type in their date or use the datepicker, or do you present them with a list of available dates?

    Hi Chris, thank you for your response.

    I prefer a date picker. But I'm open to options and your suggestions.

    Awaiting your response.

    Thanks

    To show the previously submitted dates (the dates where the hall is already booked) you could use a shortcode like this to say "Hall is unavailable on these dates" and then list the date. Here is the shortcode I used to grab one field for all entries in one specific form: http://pastebin.com/FUF9HA6B

    That would be one approach you mentioned in your second post.

    The other way would require using the gform_validation hook and some custom code to check the date entered against all dates already submitted. http://www.gravityhelp.com/documentation/page/Gform_validation

    You can use the same function to pull out the field from all the entries to compare to the submitted data.
