That functionality is provided on the front end by JavaScript. You can use jQuery to modify the date pickers on your web page. You can find documentation here: <a href="http://jqueryui.com/datepicker/" rel="nofollow">http://jqueryui.com/datepicker/</a></p> <p>Regarding the number of days between the two, you will have to write the PHP to do the math yourself. You can compare dates and then store the number of days, in the entry, using the gform_pre_submission_filter <a href="http://www.gravityhelp.com/documentation/page/Gform_pre_submission_filter" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_pre_submission_filter</a></p> <p>This sort of data-based functionality is not built in to Gravity Forms but can be added by using the built in hooks and filters offered by Gravity Forms. </p> https://legacy.forums.gravityhelp.com/topic/check-in-check-out-date-selection#post-100307 Sat, 08 Dec 2012 07:57:08 +0000 geekyumang 100307@https://legacy.forums.gravityhelp.com/ <p>I have to setup the form in such a way that Check Out date is post Check In date selected and also, I am able to find out the number of days between the two.</p> <p>It would be helpful if someone could post on how to achieve this. </p>
