Then using <a href="http://www.gravityhelp.com/documentation/page/Gform_pre_submission" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_pre_submission</a> you can calculate the difference in dates based on what they selected and populate your hidden field so the value is sent to the database.</p> <p>To figure out the difference, you'll have to come up with some PHP code using the date function.<br /> <a href="http://php.net/manual/en/function.date.php" rel="nofollow">http://php.net/manual/en/function.date.php</a> </p> https://legacy.forums.gravityhelp.com/topic/calculate-a-date#post-58674 Fri, 11 May 2012 10:57:19 +0000 clicknathan 58674@https://legacy.forums.gravityhelp.com/ <p>Would anyone know how I might calculate a month based on the date a user input? </p> <p>This isn't specific to the new "calculations" functionality or anything, but probably something that involves a little extra work on my part.</p> <p>For example, I want to allow the user to choose between three options in a dropdown question that asks, "How soon do you want this?":</p> <p>1. 1-13 days<br /> 2. 14 - 21 days<br /> 3. 22 days or more</p> <p>And then have a date input (that isn't shown to the user, just for internal purposes) display the applicable month. So depending on what they chose:</p> <p>1. We'd leave the month as the current month.<br /> 2. We'd put it as the following month.<br /> 3. We'd put it as 2 months out.</p> <p>Any ideas? </p>
