I gave it a try, but did not work for me. It was passing a value of 1 instead of the actual # of days.</p> <p>I'll check with Cart66....but, I really appreciate the response. Gives me some place to start.</p> <p>Louise </p> https://legacy.forums.gravityhelp.com/topic/start-date-end-date-calculate-of-days-how#post-57054 Mon, 30 Apr 2012 16:59:34 +0000 Alex Cancado 57054@https://legacy.forums.gravityhelp.com/ <p>Hello Louise,<br /> I am not familiar with the details on how Cart66 integrates with Gravity Forms, so I can't give you a complete code snippet. However, you can use one of our hooks to calculate the number of days between two dates, come up with a total price based on a daily rate and finally store that result into another Gravity Forms field. Hopefully this will help you achieve your goal. If you still aren't able to make this work, I would suggest reaching out to the Cart66 folks. as they are the ones who built the integration with Gravity Forms and should be more familiar with it.</p> <pre><code>add_action(&quot;gform_pre_submission&quot;, &quot;pre_submission_handler&quot;); function pre_submission_handler($form){ $start_date = $_POST[&quot;input_2&quot;]; //NOTE: replace 2 with your actual start date input ID $end_date = $_POST[&quot;input_3&quot;]; //NOTE: replace 3 with your actual end date input ID $days = gf_date_diff($start_date, $end_date); $daily_rate = 6.00; $_POST[&quot;input_4&quot;] = floatval($daily_rate) * floatval($days); //NOTE: replace 4 with your actual total field ID (field that will be passed to Cart66) } function gf_date_diff($start, $end) { $start_ts = strtotime($start); $end_ts = strtotime($end); $diff = $end_ts - $start_ts; return round($diff / 86400); }</code></pre> <p>Cheers,<br /> Alex </p> https://legacy.forums.gravityhelp.com/topic/start-date-end-date-calculate-of-days-how#post-57051 Mon, 30 Apr 2012 16:48:22 +0000 studio57designs 57051@https://legacy.forums.gravityhelp.com/ <p>Ok, thanks so much!

Is it possible to enter both start and end date and then calculate the # of days?</p> <p>For example, the customer enters the start date of 5/1/2012 and end date of 5/6/2012 and the daily rate is $6.00 - we'd like to see the form pass the amount as $30 (5 days x $6) to the cart.</p> <p>Is there a way to create a function to do that or is it already built in and I've just not found it?</p> <p>Thanks,</p> <p>Louise </p>
